It lets users configure MCP servers once and connect every AI client (Cursor, Claude Desktop, VS Code, Windsurf) through a single endpoint, with credentials encrypted in the OS keychain instead of plain-text JSON files. + +A more detailed map of the workspace lives in [`CLAUDE.md`](CLAUDE.md) at the repo root — read it for the crate layout, frontend architecture, and cross-project context. This file captures the minimum an agent needs to make safe, useful changes here. + +## Workspace Layout + +``` +mcp-mux/ +├── apps/desktop/ # Tauri shell — React frontend (src/) + Rust Tauri commands (src-tauri/) +├── crates/ +│ ├── mcpmux-core/ # Domain entities, repository traits, service layer, EventBus +│ ├── mcpmux-gateway/ # Axum gateway — routing, OAuth refresh, FeatureSet filtering +│ ├── mcpmux-storage/ # SQLite + AES-256-GCM field encryption + OS keychain +│ └── mcpmux-mcp/ # MCP protocol client wrapper (rmcp SDK) +├── packages/ui/ # Shared UI components (`@mcpmux/ui`) +├── schemas/ # JSON Schemas surfaced in the Monaco editor +└── tests/ # Rust integration, TS unit (vitest), desktop E2E (WDIO), web E2E (playwright) +``` + +## Build & Dev Commands + +Run everything from `mcp-mux/`: + +| Command | What it does | +|---------|--------------| +| `pnpm setup` | First-time dev environment setup (PowerShell on Windows). | +| `pnpm dev` | Tauri desktop dev mode (Rust + React hot-reload). | +| `pnpm dev:web` | Web UI only via Vite — no Rust, no Tauri shell. | +| `pnpm build` | Production Tauri build for the current platform. | +| `pnpm validate` | Full correctness gate — runs the items below in sequence. | +| `pnpm lint` | ESLint (recursive) + `cargo clippy --workspace -- -D warnings`. | +| `pnpm lint:fix` | Auto-fix lint issues. | +| `pnpm format` | `prettier --write .` + `cargo fmt --all`. | +| `pnpm format:check` | Formatting check (no writes). | +| `pnpm typecheck` | Recursive TypeScript typecheck. | + +**Before claiming a change is done**, run `pnpm validate` (or the relevant subset) — it mirrors what CI enforces. + +## Testing + +| Command | Scope | +|---------|-------| +| `pnpm test` | Rust + TypeScript, everything. | +| `pnpm test:rust` | `cargo nextest run --workspace`. | +| `pnpm test:rust:unit` | `cargo nextest run --workspace --lib`. | +| `pnpm test:rust:int` | `cargo nextest run -p tests` — integration crate in `tests/rust`. | +| `pnpm test:rust:doc` | `cargo test --workspace --doc`. | +| `pnpm test:ts` | Vitest run (`tests/ts/vitest.config.ts`). | +| `pnpm test:ts:watch` | Vitest watch. | +| `pnpm test:e2e` | Desktop E2E via WebDriver IO — requires `MCPMUX_REGISTRY_URL`. | +| `pnpm test:e2e:file -- tests/e2e/specs/foo.ts` | One WDIO spec file. | +| `pnpm test:e2e:grep -- "test name"` | WDIO tests matching a name. | +| `pnpm test:e2e:web` | Playwright on the web UI. | +| `pnpm test:coverage` | `cargo llvm-cov` + Vitest coverage. | + +Prefer narrow commands over `pnpm test` while iterating — the full suite is slow. + +## Code Style + +- **Rust:** 100-char max width, 4-space indent. Clippy runs with `avoid-breaking-exported-api = false`; all warnings are denied in CI. +- **TypeScript / JSX:** Prettier — single quotes, 2-space indent, 100-char width, trailing commas (es5), Tailwind CSS plugin for class ordering. +- **Path aliases:** `@/` → `apps/desktop/src/`; `@mcpmux/ui` → `packages/ui`. +- **No emojis in code or commits** unless the user explicitly asks for them. +- **Comments:** only when the *why* is non-obvious. Identifiers should explain the *what*. + +## Commit & PR Guidelines + +- Commits must be **signed off** (DCO): `git commit -s -m "..."`. CI rejects unsigned commits. +- Prefer conventional-style subjects — releases use release-please for semantic versioning. +- PRs follow [`.github/pull_request_template.md`](.github/pull_request_template.md): describe the change, how you tested, and check the `pnpm test` / `pnpm lint` / `pnpm typecheck` boxes. +- Don't bypass hooks (`--no-verify`) or DCO signing unless explicitly told to. + +## Platform Gotchas + +### Child-process flags + +Anything that spawns a child process (stdio MCP servers, installers, etc.) **must** go through `mcpmux_gateway::pool::transport::configure_child_process_platform()`. That helper applies: + +- **Windows:** `CREATE_NO_WINDOW` (`0x08000000`) — release builds use `windows_subsystem = "windows"`, so without this the OS briefly flashes a console window when a child starts. +- **Unix:** `process_group(0)` — stops SIGINT/SIGTSTP from the parent terminal from tearing down the child. + +`tokio::process::Command` already exposes `creation_flags()` (Windows) and `process_group()` (Unix). **Do not** import `std::os::*::process::CommandExt` — those traits are unused with Tokio's `Command` and trigger clippy. + +### Cross-platform CI + +- The pre-commit hook runs `cargo clippy --workspace -- -D warnings` on your dev machine. +- `#[cfg(unix)]` only compiles on Unix; `#[cfg(windows)]` only on Windows. CI is Linux, so Windows-gated code is **not** linted in CI, and Unix-gated code is not linted on a Windows dev box. +- When you touch platform-conditional code, check the *other* platform compiles before pushing — CI won't catch a Windows-only clippy regression. + +### Secret handling + +- Never log tokens, API keys, headers with auth material, or raw OAuth responses. Use the existing sanitised-log helpers in `mcpmux-gateway`. +- Credentials encrypt at rest via AES-256-GCM in SQLite plus DPAPI (Windows) / OS keychain (macOS, Linux). Don't add new code paths that persist secrets any other way. +- Secrets should be wiped from memory after use via `zeroize`. +- The gateway binds to `127.0.0.1`. Don't bind to `0.0.0.0` or expose it on the network. + +## Frontend Notes + +- Entry point: `apps/desktop/src/main.tsx` → `App.tsx`. +- Global state: a single Zustand store at `src/stores/appStore.ts`. +- Key hooks: `useServerManager` (server CRUD), `useSpaces` (workspace switching), `useDomainEvents` (Rust-side EventBus listener), `useDataSync`. +- UI: React 19, Tailwind CSS, Lucide icons, Monaco Editor for JSON config surfaces. +- Open external URLs through `openExternal` in `apps/desktop/src/lib/contribute.ts` — it routes through the Tauri opener plugin so links open in the user's default browser, not the webview. +- For UI changes, launch `pnpm dev` and exercise the feature in the running app before reporting done — typecheck and tests verify correctness, not UX regressions. + +## Rust Architecture Cues + +- Cross-layer communication goes through the `EventBus` in `mcpmux-core`. Prefer emitting a domain event over reaching across module boundaries directly. +- Storage is behind repository traits — don't call SQLx or SQLite APIs directly from gateway or app code; add or use a repo method. +- Services are wired up via the `ApplicationServices` builders in `mcpmux-core`. New services should follow the same DI pattern. + +## MCP Specification + +The full MCP spec is vendored at `../modelcontextprotocol/docs/specification/`. Default to the latest stable version (`2025-11-25`) and **read the relevant section before** implementing or modifying protocol behaviour (transports, lifecycle, capability negotiation, OAuth flows, tools / resources / prompts). For features targeting a specific protocol version, use that version's folder. + +## Server Definitions + +Server catalog entries live in the separate [`mcp-servers`](https://github.com/mcpmux/mcp-servers) repo — **not here**. If a task involves adding, editing, or fixing a server definition, switch to that repo and follow its `AGENTS.md`. + +## Things Not To Do + +- Don't add backwards-compatibility shims, deprecated aliases, or `// removed` placeholder comments when removing code — delete it cleanly. +- Don't introduce new fallbacks or input validation for states that are already framework-guaranteed. Trust internal invariants; validate only at the boundary (user input, external APIs). +- Don't edit generated files: `CHANGELOG.md`, release-please manifests, `bundle/*.json` in sibling repos, `packages/ui/dist`. +- Don't commit screenshots, videos, or large binaries to the repo — link out instead. diff --git a/Cargo.lock b/Cargo.lock index 987df857..a714f86c 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -4176,9 +4176,9 @@ dependencies = [ [[package]] name = "rmcp" -version = "0.17.0" +version = "1.5.0" source = "registry+https://github.com/rust-lang/crates.io-index" -checksum = "8a0ce46f9101dc911f07e1468084c057839d15b08040d110820c5513312ef56a" +checksum = "67d69668de0b0ccd9cc435f700f3b39a7861863cf37a15e1f304ea78688a4826" dependencies = [ "async-trait", "base64 0.22.1", @@ -4211,9 +4211,9 @@ dependencies = [ [[package]] name = "rmcp-macros" -version = "0.17.0" +version = "1.5.0" source = "registry+https://github.com/rust-lang/crates.io-index" -checksum = "abad6f5f46e220e3bda2fc90fd1ad64c1c2a2bd716d52c845eb5c9c64cda7542" +checksum = "48fdc01c81097b0aed18633e676e269fefa3a78ec1df56b4fe597c1241b92025" dependencies = [ "darling 0.23.0", "proc-macro2", @@ -5454,6 +5454,7 @@ dependencies = [ name = "tests" version = "0.0.2" dependencies = [ + "anyhow", "async-trait", "axum", "chrono", diff --git a/Cargo.toml b/Cargo.toml index a174a8b7..059f29a4 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -58,7 +58,7 @@ os_pipe = "1" # MCP Protocol # NOTE: Never use local path dependency - E:\one-mcp\rust-sdk is for source lookup only -rmcp = { version = "0.17.0", features = [ +rmcp = { version = "1.5", features = [ "client", "server", "transport-io", diff --git a/README.md b/README.md index a4444377..64d13a80 100644 --- a/README.md +++ b/README.md @@ -77,7 +77,7 @@ Lightweight and cross-platform — built in Rust with Tauri 2, McpMux uses minim } ``` -**3.** Done.

Tool-level enable can be added later as a degenerate case if a real use case shows up. | +| 2 | Default scope | **Session** (default), with `scope: "workspace"` as an opt-in arg | Session is the low-risk default; ephemerality is the point. Workspace scope falls back to the existing `WorkspaceBinding` write path, reusing PR #151 plumbing. | +| 3 | Composition with bindings | **Additive over `WorkspaceBinding`**: `effective = (binding ∪ session_enabled) − session_disabled` | Lets users keep their stable per-project bundle AND opportunistically add a server for a single session. Subtractive disable lets them mute a noisy server temporarily without unbinding. | +| 4 | Override lifetime | **In-memory, dies with `mcp-session-id`** | Matches `SessionRootsRegistry` semantics introduced by PR #151. Restart of gateway or client = fresh start. No DB persistence; no migration. | +| 5 | Approval flow | Session enables auto-allow by default (configurable); workspace writes require approval (existing flow) | Session-scope is ephemeral and safer than persistent state. App setting `gateway.session_overrides_require_approval` (default `false`) lets paranoid users gate everything. | +| 6 | Audit | Every override emits a `DomainEvent::MetaToolInvoked` (existing path) | No new event variants; the audit log already renders meta-tool calls. The "decision" field gets `"session_override"` for auto-allowed session writes. | +| 7 | Manifest format | `mcpmux_list_servers` returns server roster with `{id, name, tool_count, status}` where status ∈ `enabled_via_binding \| enabled_via_session \| disabled_via_session \| inactive` | The LLM needs to see current state, not just availability — otherwise it can't reason about whether to call enable or just call the tool. | +| 8 | Tier-0 placement | New `SessionOverrideRegistry` consulted **inside** `FeatureService` materialization, not as a new resolver tier | Resolver already returns `(space, feature_set_ids)` cleanly.

Adding tool-level later is additive — same approval flow, more specific `qualified_name` list. No real evidence yet that tool-level matters more than server-level for token budget. | +| Persistent session preferences across gateway restarts | Process-lifetime is the design — sessions die when the client reconnects. If a user wants stickiness, they should use a binding. Adding persistence here would duplicate the binding system poorly. | +| Auto-enable on tool-call hint ("LLM tried to call `github_create_issue` → silently enable github first") | Requires a "shadow tool list" mechanism in the handler (advertise more than is currently active). Possible follow-up, but design isn't obvious — silent enable defeats the audit trail. | +| Cross-client session sharing | `mcp-session-id` is per-MCP-session; two Cursor windows have two sessions and two override sets. By design — independent contexts. | +| Override expiry / TTL | Sessions are already ephemeral. A TTL would be a different concept and isn't asked for. | +| Tool-level disable inside an already-enabled server | Use `mcpmux_create_feature_set` + `mcpmux_bind_current_workspace` (PR #151's existing path) for fine-grained subsets. | + +--- + +## Key files referenced + +| File | Why | +| ---- | --- | +| [`crates/mcpmux-gateway/src/services/meta_tools/tools.rs`](../../crates/mcpmux-gateway/src/services/meta_tools/tools.rs) | Where the three new `MetaTool` impls land.

The LLM must guess parameter names (`issueNumber` vs `issue_number`) because schemas are not exposed through discovery APIs — only through client-side descriptor files that lag behind dynamic enablement. + +Competing gateways ([MikkoParkkola/mcp-gateway](https://github.com/MikkoParkkola/mcp-gateway), [abdullah1854/MCPGateway](https://github.com/abdullah1854/MCPGateway)) solve this with a **fixed meta surface** (~14–19 tools) and **progressive disclosure**: search → load schema → invoke. McpMux already has half the plumbing (`mcpmux_list_servers`, `mcpmux_enable_server`, `mcpmux_list_all_tools`) but lacks search-with-schema and a single invoke entry point. + +The user-facing ask (May 2026 session): + +> I'd rather 1–2 more calls that actually work well than hundreds of tool defs I can't call correctly. + +This doc defines that model for McpMux while preserving its product strengths: OS keychain credentials, Spaces, FeatureSets, per-client auth, and the server registry. + +--- + +## Decisions + +| # | Decision | Choice | Rationale | +| - | -------- | ------ | --------- | +| 1 | Client `tools/list` shape | **Meta tools + optional surfaced backend tools only** — never the full backend catalog | Fixes context bloat. Backend tools are invoked through `mcpmux_invoke_tool`, not registered in the client tool list (except surfaced exceptions). | +| 2 | Discovery API | **`mcpmux_search_tools` with `detail_level`**: `name` \| `description` \| `schema`** | Replaces dumping `mcpmux_list_all_tools` for agent workflows. Supports server_id filter, pagination, and query string. Start with substring + server_id filter; TF-IDF semantic rank is Phase D optional. | +| 3 | Schema API | **`mcpmux_get_tool_schema`** — single or batch, optional `compact: true`** | Agents must read schemas before invoke without relying on Cursor descriptor JSON files. Batch load for multi-tool workflows (e.g. issue read + comment write). | +| 4 | Invoke API | **`mcpmux_invoke_tool({ server_id, tool, args, filter? })`** — one entry point for all backend calls | Mirrors `gateway_invoke`. Routes through existing `RoutingService::call_tool` after permission checks. Optional `filter` arg activates result shaping (Phase B). | +| 5 | FeatureSet semantics | **FeatureSets define what is *invokable*, not what appears in `tools/list`** | Binding / grant / session-enable controls the candidate pool for search + invoke. Security boundary stays meaningful without polluting client context. | +| 6 | Surfaced tools escape hatch | **FeatureSet members may mark tools `surfaced: true` (0–N per set)** — promoted into `tools/list` for one-hop hot paths | Default: **zero surfaced everywhere**, including built-in bundles. No bundle auto-promotes backend tools. Opt-in only via FeatureSet editor (Phase C). | +| 7 | Invoke authorization | **Fail closed** — `invoke_tool` rejects when target server/tool is outside effective permission set | Same composition as today: `(binding_servers ∪ session_enabled) − session_disabled`, then FeatureSet member filter. Empty effective set → invoke denied with actionable error, not silent proxy. | +| 8 | Session enable/disable | **Keep existing `mcpmux_enable_server` / `mcpmux_disable_server`** — they gate invoke/search eligibility, not `tools/list` size | Mental model unchanged: "turn on github" expands what search/invoke can reach. `tools/list` size stays ~constant. | +| 9 | Error messages | **Actionable, bounded errors** — no dumping full available-tool lists | e.g. `"github inactive → mcpmux_enable_server('github')"`, `"unknown tool → did you mean github_list_issues?"`. Optional Levenshtein suggestions (Phase D). | +| 10 | Rollout | **Hard cut — no legacy opt-out** | Non-surfaced backend tools never appear in `tools/list` and direct `call_tool` is rejected with a redirect to `mcpmux_invoke_tool`. **Exception:** FeatureSet members marked `surfaced: true` are promoted into `tools/list` and callable in one hop. No `expose_backend_tools_in_list` setting. Ship in one release; document migration in CHANGELOG. | +| 11 | `mcpmux_list_all_tools` | **Keep as operator/diagnostic tool** — not the primary agent discovery path | Still useful for FeatureSet authoring and UI. Doc + descriptions steer agents to `search_tools`. Consider server_id filter arg in Phase A to avoid 855 KB dumps. | +| 12 | Result shaping scope | **Phase B only on `invoke_tool`** — opt-in via explicit `filter`: `max_rows`, `max_bytes`, `fields`, `format: summary`. Omit filter → backend response as-is. | Agents pass `filter` when they know a tool returns large payloads. No default truncation. | +| 13 | REST / OpenAPI capabilities | **Out of scope here** — Phase E / separate planning doc | [`web-admin-remote-access.md`](./web-admin-remote-access.md) covers admin REST, not REST→MCP capability YAML.

Hyphen suffix only — underscores are stripped by `normalize_server_id` and reserved as the tool-name delimiter. | +| 4 | Definition source | **Copy `cached_definition` from source install** into clone at creation time | Clone is self-contained for offline/gateway startup. Registry updates do not auto-propagate — acceptable tradeoff for v1; document in UI. | +| 5 | Prefix / alias | **Auto-set alias = suffix** (e.g. `posthog-work` → tools prefixed `posthog-work_*`) | Reuses `PrefixCacheService` first-come assignment. User can override alias in configure step. | +| 6 | Credentials | **Never copy secrets** — clone starts with empty `input_values` / no OAuth; user configures fresh | Prevents accidental credential sharing. Clone wizard opens configure flow immediately after create. | +| 7 | Source tracking | **`InstallationSource::ManualEntry`** + optional `cloned_from: Option` metadata on `InstalledServer` | Distinguishes registry installs from clones in UI (`SourceBadge`). `cloned_from` is display-only in v1 — not a FK. | +| 8 | Registry dedup UX | **"Add another account" disabled when source is already a clone-of-clone** (max depth 1) or when suffix collision detected | Prevents unbounded ID sprawl (`posthog-work-work-work`).

The killer detail: the plumbing for this is already wired — `SessionOverrideRegistry` exists, `FeatureService::get_tools_for_grants` is already the materialization chokepoint, per-peer `tools/list_changed` already fires after meta-tool writes. The change is additive: one new field on the registry, one new filter step at the bottom of the existing composition rule, two new `MetaTool` impls. + +A note on naming: `mcpmux_pin_this_session` is referenced verbatim in the meta-tools module docstring, in `SettingsPage.tsx`, in the approval-broker tests, and in the WDIO meta-tools spec — leftover from an early draft when the tool was intended to ship with the original meta-tools work. Reusing the name keeps every existing reference truthful instead of forcing a docs-only renaming pass. + +--- + +## Decisions + +| # | Decision | Choice | Rationale | +| - | -------- | ------ | --------- | +| 1 | New tool vs extend existing | **One new write tool (`mcpmux_pin_this_session`) + one new write tool (`mcpmux_clear_session_pin`)** — do not overload `enable_server`/`disable_server` | Server-level and tool-level have different composition semantics (additive overlay vs exclusive replacement). Conflating them would force every call site to disambiguate. Two narrowly-scoped tools keep the surface clean. | +| 2 | Composition with existing overrides | **Exclusive replacement applied AFTER server-level composition.** Effective = `(binding_servers ∪ session_on) − session_off`, materialize tools, then if `pinned_tools` non-empty: filter to `tools ∩ pinned_tools`. | Pin semantically means "lock to this set." Layering it on top means a pin to `["github_create_issue"]` works whether `github` is enabled via binding, via session-enable, or both — the user expresses intent (which tools they want) without caring about how those tools got into the candidate pool. | +| 3 | Empty list semantics | **Empty `tool_qualified_names` rejected as invalid argument** — clearing is done via `mcpmux_clear_session_pin` | Avoids two paths for the same operation. Reject-on-empty matches `mcpmux_create_feature_set` which already rejects empty `tool_qualified_names`. | +| 4 | Explicit clear vs implicit | **Dedicated `mcpmux_clear_session_pin` tool** — no args, operates on caller's session | Forces an intentional unpin, audited like any other write. Letting "pin with full list" act as clear would require the LLM to call `list_all_tools` first just to undo — wasteful and ambiguous. | +| 5 | Naming | **`mcpmux_pin_this_session`** | Matches every existing stale reference (mod.rs docstring, SettingsPage copy, approval tests, WDIO spec). The "this_session" suffix makes scope intuitive — ergonomic mirror to the existing `mcpmux_bind_current_workspace`. | +| 6 | Scope support | **`scope: "session"` (default) + `scope: "workspace"`** mirroring `mcpmux_enable_server` | Session is the ephemeral knob. Workspace persists the same pin set via a new auto-named custom FeatureSet bound to the caller's first reported root — single approval-gated atomic op instead of two-step `create_feature_set` + `bind_current_workspace`. | +| 7 | Workspace-scope FeatureSet naming | **Auto-named `"Pinned: {root_basename} {YYYY-MM-DD HH:MM}"`** unless caller supplies optional `name` arg | Discoverable in the Workspaces UI after creation. Optional override lets the LLM name it meaningfully (`"Gmail send-only"`) when the user prompt makes intent clear. | +| 8 | Approval default | **Session: auto-allow, gated by existing `gateway.session_overrides_require_approval`. Workspace: always required via `ApprovalBroker`.** | Reuses the existing setting — no new toggle. Session pin is ephemeral (dies with the MCP session) so the same risk profile as `enable_server`/`disable_server` applies. Workspace persists state, so it always shows the approval dialog with the full tool list in the diff. | +| 9 | Override store layout | **Extend `SessionOverrideRegistry` with `pinned_tools: DashMap>`** — do not introduce a sibling registry | Same lifecycle (process-only, dies with session reap), same factory, same GC hook in `MCPNotifier`. Keeping it co-located concentrates session-scoped override state in one struct so `reap_dead_sessions` only needs to know about one type. | +| 10 | Validation timing | **Validate every qualified name exists in caller's resolved Space at call time** (look up via `server_feature_repo::list_for_space`) | Rejects typos and stale tool names up-front with a clear error. Storing unresolved names would let the pin silently shrink to nothing if a server becomes unavailable. | +| 11 | Audit decision string | **`"session_pin"` for session-scope writes, `"allow_once"` for workspace-scope approvals** | Distinct from `"session_override"` used by enable/disable so the audit log + Workspaces UI can render pin-specific rows ("pinned 12 tools" vs "enabled github"). | + +--- + +## The Model + +### Override store extension + +```text +SessionOverrideRegistry { + enabled : DashMap>, // existing + disabled : DashMap>, // existing + pinned_tools : DashMap>, // NEW +} +``` + +`pinned_tools[sid]` stores fully qualified tool names (e.g. `"github_create_issue"`, `"google-workspace-mcp-uvx_send_email"`) — the same format `mcpmux_list_all_tools` returns and `mcpmux_create_feature_set` accepts. Empty/missing = no pin = pass-through. + +GC: `SessionOverrideRegistry::remove(session_id)` extended to drop `pinned_tools[sid]` alongside the existing two sets. `MCPNotifier::reap_dead_sessions` already calls `remove` per reaped session — no notifier change needed. + +### Composition rule + +The existing composition in `FeatureService::get_tools_for_grants` runs steps 1–6; this doc adds steps 7–8: + +```text +1.

Prompts and resources are unaffected — pinning is a tool-budget concept, not a capability-restriction concept. `get_prompts_for_grants` and `get_resources_for_grants` skip steps 7–8. + +A pin that resolves to zero matches (every name filtered out by `is_available`) returns an empty tool list. The caller's `tools/list` will show no tools; calling `mcpmux_clear_session_pin` is the recovery path.

This doc defines a **web admin mode**: an optional HTTP server that serves the built React SPA and exposes a REST API mirroring Tauri commands, gated by Cloudflare Access at the edge. + +--- + +## Decisions + +| # | Decision | Choice | Rationale | +| - | -------- | ------ | --------- | +| 1 | Deployment model | **Single-user homelab** — one McpMux instance on Gondor, one operator | Avoids multi-tenant auth, cloud KMS, and per-user DB isolation. The Rust process still runs locally with OS keychain access. | +| 2 | Auth | **Cloudflare Access at the tunnel edge** — app trusts `CF-Access-Jwt-Assertion` when `gateway.admin_trust_cf_access` is enabled | No login UI to build. Same pattern as `b.joe-hassio.com` (Beeper). Reject requests without a valid JWT when admin mode is enabled. | +| 3 | Admin server placement | **Separate Axum router on configurable port** (default `45819`), not mixed into MCP gateway routes | Keeps MCP protocol surface unchanged. Admin and MCP can be tunneled independently (`mux.joe-hassio.com` vs `mcp.joe-hassio.com`). Easier to disable admin without stopping the gateway. | +| 4 | Static UI | **Serve `frontendDist` from the Tauri build** at `/` with SPA fallback | Reuses the existing React app. No separate web bundle. | +| 5 | API shape | **REST JSON at `/api/v1/*`** mirroring Tauri command names (kebab → snake mapping) | Predictable mapping: `get_gateway_status` → `GET /api/v1/gateway/status`. One handler module per Tauri command group. | +| 6 | Frontend transport | **Transport abstraction in `lib/api/`** — `invoke()` in Tauri, `fetch()` in web mode | Detect via `window.__TAURI__` or build-time `import.meta.env.VITE_ADMIN_WEB`. Same function signatures, different backend. | +| 7 | OAuth consent | **Re-enable guarded HTTP consent endpoint** for web admin only — `POST /api/v1/oauth/consent/approve` behind CF Access + CSRF token | Production desktop keeps Tauri-IPC-only consent (existing security model). Web mode needs an HTTP path because there is no Tauri shell on Weathertop. | +| 8 | Bind address | **Default `127.0.0.1:45819`** — same loopback-first posture as MCP gateway | CF tunnel reaches localhost; no need to bind `0.0.0.0`. `AGENTS.md` loopback rule preserved. | +| 9 | Event streaming | **SSE at `/api/v1/events`** bridging existing `EventBus` | Replaces Tauri event listeners (`useDomainEvents`) in web mode. Desktop keeps Tauri events. | +| 10 | Scope phasing | **Read-only views first, then writes, then OAuth** | Each phase is independently testable behind CF Access.
