Per-object authorisation runs inside `invokeTool()` and yields a +structured `{isError: true, error: 'forbidden', ...}` payload on failure so the LLM can +explain the denial in natural language. + +**Alternatives considered:** filtering the catalogue per caller (would force the LLM to +re-fetch tools every turn; complicates caching in the dispatcher; punts the v2 hybrid +mode prematurely). **Why this:** matches the contract from hydra ADR-034 and keeps the +LLM's mental model stable. + +### D3: Service-container alias key `IMcpToolProvider::decidesk` + +Registration uses +`$context->registerServiceAlias('OCA\\OpenRegister\\Mcp\\IMcpToolProvider::decidesk', +DecideskToolProvider::class)` inside the existing `register()` body in +`lib/AppInfo/Application.php`. OpenRegister's `McpToolsService` enumerates aliases +matching the prefix `OCA\OpenRegister\Mcp\IMcpToolProvider::` and resolves each one. + +**Alternatives considered:** Event-based registration (heavier, no benefit at this +scale); auto-discovery by scanning `OCA\*\Mcp\` namespaces (fragile, breaks PHP +autoload semantics). **Why this:** matches the locked OR dispatcher contract; one line +change in `Application.php`. + +### D4: Strict validation pipeline — args → auth → state → business logic + +Each handler runs the same four-phase pipeline: + +1. **Validate arguments** against the tool's `inputSchema` (UUID format, enum values, + numeric ranges, required fields). Failure → `{error: 'invalid_arguments'}`. +2. **Authorise** the caller against the target object. Failure → `{error: 'forbidden'}`. +3. **Check state** (for `startMeeting`: must be `scheduled`). Failure → + `{error: 'invalid_state'}`. +4. **Delegate to service** and shape the success payload (including `sources`). + +**Alternatives considered:** auth-first ordering. **Why arg-first:** users typing bad +input shouldn't trigger expensive authorisation lookups; arg validation is cheap. +**Why not state-before-auth:** state checks would leak existence to unauthorised +callers. + +### D5: Sources array is mandatory on every success path + +Every successful tool return carries a `sources: array<{type, uuid, url, label}>` key. +The widget's `CnAiMessageList` (in `@conduction/nextcloud-vue`) renders these as +`[label]` inline citations. The truncation cap (20 items, with `sourcesTruncated` ++ `sourcesTotalCount`) prevents pathological tool calls from blowing up the LLM +context. + +**Alternatives considered:** optional sources, sources-by-request, sources via a +secondary tool call. **Why mandatory + capped:** citations are the load-bearing UX +feature; making them optional invites apps to skip them and degrade the chat +experience. + +## Reuse Analysis + +The provider is a thin adapter — almost all behaviour is reused. + +| Code path | Source | Reuse strategy | +|---|---|---| +| `IMcpToolProvider` interface | `openregister/openregister` (composer dep) | Declared in `require`; new dependency. Imported in `lib/Mcp/DecideskToolProvider.php` via `use`. | +| List recent meetings | `MeetingService` (existing) | Constructor inject; call existing list method with a per-user visibility filter. | +| Get meeting + agenda + decisions + action items | `MeetingService` + `AgendaService` + `TaskService` (existing) | Compose three calls into a single result object. | +| Transition `scheduled` → `in-progress` | `MeetingService::startMeeting()` (existing) | One call; provider only handles auth and result shaping. | +| List open action items | `TaskService` (existing) | Filter `completed = false`, optional `assigneeUserId = currentUser` when `scope=mine`. | +| Create action item | `TaskService::createForMeeting()` (existing) | One call. | +| Chair / participant / admin auth | `requireChairOrSecretary` / `requireChairOrAdmin` patterns in `lib/Controller/*Controller.php` | Lifted into private methods on the provider — controllers untouched. Returns boolean (auth pass/fail) rather than `JSONResponse` since the provider is not a controller. | +| Test stubs for `OCA\OpenRegister\*` | `tests/Stubs/` (existing) | Reused for unit tests that need to mock the interface without the full OR runtime. | +| Deep-link URLs | Existing route conventions (`/apps/decidesk/meetings/`, etc.) | Built as string concatenation in a private `buildDeepLink($type, $uuid)` helper on the provider. | + +The provider adds NO new business logic. If a tool needs a behaviour the services don't +already expose, that's a signal to extend the service — not to inline logic in the +provider. + +## Seed Data + +**N/A.** This change introduces no new OpenRegister schemas, registers, or objects, and +therefore no seed data. The 5 tools operate on existing decidesk objects (meetings, +agenda items, decisions, action items) that are seeded by the existing +`p2-meeting-management` / `p2-minutes-and-decisions` changes. + +## Declarative-vs-Imperative (ADR-031) + +**N/A.** Tool dispatch is a controller-style imperative pattern: a single class with +five handler methods, each delegating to existing services. No part of this change +touches: + +- OpenRegister lifecycles or state machines (the only state change uses an existing + imperative `MeetingService::startMeeting()` call). +- Derived fields, aggregations, or computed properties. +- Notifications (the chat widget renders results client-side from the `sources` array; + no email/push/in-app notifications dispatched by this change). +- Declarative relations / widgets / register-level metadata. + +ADR-031's guidance to prefer declarative over imperative does not apply because the +domain here (tool dispatch routed by `$toolId`) is intrinsically imperative — a `match` +expression on a closed enum of tool ids is the simplest possible expression of the +contract. + +## Risks / Trade-offs + +| Risk | Mitigation | +|---|---| +| **R1 — Schema drift between `getTools()` inputSchema and underlying service signature.** If `TaskService::createForMeeting()` adds/changes a required parameter, `decidesk.addActionItem`'s `inputSchema` will silently drift out of sync. | Integration test round-trips a real `decidesk.startMeeting` and `decidesk.addActionItem` end-to-end through the DI container against a fixture. Unit tests assert the descriptor shape. CI fails on drift. | +| **R2 — LLM hallucinating UUIDs.** The model may invent a plausible-looking UUID that doesn't reference any real object, or paste one from an unrelated tenant. | UUID format validation runs before lookup (REQ-DMCP-007). Lookups that resolve to no object return `not_found`. Authorisation runs before existence-leaking error text. | +| **R3 — ADR-005 IDOR (CRITICAL).** Every action tool MUST do per-object auth. Per user memory, `hydra-gate-orphan-auth` previously caught dead auth methods in decidesk; the stub-method exploit risk is logged on decidesk#60. | Every helper invoked in `invokeTool()` MUST actually run (no `return true` stubs). Unit tests assert that the auth-failure path returns `forbidden` for every object-targeting tool. Hydra gate-9 (semantic auth) will catch chair-only routes that lack `requireChair`. | +| **R4 — Semantic auth gate.** The provider is not a controller, so `#[NoAdminRequired]` attributes don't apply. Chair-only tools (`startMeeting`) still need a semantic chair-check. | Provider declares an internal `requireChair($meetingUuid, $userId): bool` helper; the unit test for `decidesk.startMeeting` explicitly asserts the non-chair path returns `forbidden`. Hydra gate-9 reviewer instructed to inspect `lib/Mcp/DecideskToolProvider.php` even though it is not a controller. | +| **R5 — Tool result size explosion.** Deep-link inline citations on `getMeetingDetails` (meeting + N agenda items + M decisions + K action items) can grow large enough to blow the LLM's context window or the dispatcher's payload cap. | Hard cap of 20 source descriptors per result, with `sourcesTruncated: true` + `sourcesTotalCount: ` markers (REQ-DMCP-006) so the LLM can mention the truncation. The widget renders the truncation marker as `[+N more]`. | +| **R6 — No existing IMcpToolProvider test fixture.** Decidesk has stubs at `tests/Stubs/` for some OR classes but no `IMcpToolProvider` stub yet, and may not have the openregister runtime available in CI. | Add a minimal `tests/Stubs/Mcp/IMcpToolProvider.php` interface declaration mirroring the openregister signature, used only when the real package is not on the classpath. Integration test gates behind `class_exists(\OCA\OpenRegister\Mcp\McpToolsService::class)` so it skips cleanly in dev environments lacking openregister. | +| **R7 — Composer dependency ordering.** The interface lands in an openregister release that has not yet shipped. | Mark the depends_on relationship explicit in the change frontmatter (`ai-chat-companion-orchestrator`). The apply step pins the composer constraint to the first openregister tag that includes the interface (e.g. `^1.4` once tagged). Implementation cannot land before the openregister PR merges. | + +## Migration Plan + +**Forward path:** + +1. Land openregister change `ai-chat-companion-orchestrator` (PR #1466). The interface + ships in a tagged release. +2. Apply this decidesk change in a single PR targeting `development`. The PR: + - Adds `lib/Mcp/DecideskToolProvider.php`. + - Modifies `lib/AppInfo/Application.php` (one `registerServiceAlias` call). + - Modifies `composer.json` (one new `require` entry). + - Adds `tests/Unit/Mcp/DecideskToolProviderTest.php` and + `tests/Integration/Mcp/DecideskToolProviderIntegrationTest.php`. + - Optionally adds `docs/features/mcp-tools.md`. +3. PR auto-merges per the pre-production-app policy (decidesk is pre-production; admin + merge to development OK). + +**No data migration.** No schema, register, or object changes. No background job. + +**Rollback:** revert the PR. Removing `lib/Mcp/DecideskToolProvider.php` and the +`registerServiceAlias` call removes decidesk from the chat companion's tool catalogue; +the orchestrator continues to operate with whatever other providers remain. No data +cleanup required. + +**Compatibility:** opt-in by way of the chat companion being enabled in OpenRegister +admin settings. If the companion is disabled, the provider class is loaded but never +invoked. + +## Open Questions + +All three open questions were resolved by code inspection at the end of `/opsx-ff` before this design locked. Recorded here for traceability: + +- **OQ1 RESOLVED — no composer dep on openregister needed.** decidesk's existing controllers (e.g. `lib/Controller/MeetingController.php`, `lib/Controller/MinutesController.php`) already consume OR via Nextcloud's runtime autoloader (`use OCA\OpenRegister\Service\ObjectService;` with no composer entry). The `IMcpToolProvider` interface resolves through the same autoloader — installing the OR app at runtime is the only prerequisite, exactly as the widget's health probe already verifies. No `composer require` entry is added; the change pulls zero new composer deps. +- **OQ2 RESOLVED — no `createForMeeting` shim needed.** `lib/Service/TaskService.php` exposes `saveTask(array $task): array` as its create-and-update primitive (action items are stored as task records with a meeting reference). The `decidesk.addActionItem` handler in the provider calls `TaskService::saveTask([...])` directly, mapping the `inputSchema` fields (`meetingUuid`, `title`, `assigneeUserId`, `dueDate`) onto the task array. No new service method is required. +- **OQ3 RESOLVED — listing goes through OR's `ObjectService::findAll`, not `MeetingService`.** `lib/Service/MeetingService.php` exposes only single-record `create` / `read` / `update` / `delete` / `transition` / `getAvailableActions` methods (no list helper). Decidesk already calls `OCA\OpenRegister\Service\ObjectService::findAll()` for listing in other places (e.g. `MeetingController` reads list views). The `decidesk.listRecentMeetings` handler injects `ObjectService` and calls `findAll(register: , schema: , limit: N, sortDesc: 'createdAt')`. Per-user visibility filtering is enforced inside OR's `ObjectService` (the existing call sites rely on this); no decidesk-side post-filter is required. + +Additional implementation note from inspection: `startMeeting` is NOT a dedicated method on `MeetingService`. The lifecycle is owned by `MeetingService::transition($meetingUuid, $action, $currentUserId)`. The provider's `startMeeting` handler invokes `transition($meetingUuid, 'start', $userId)`. Auth flowthrough (the per-object check for chair / admin) is enforced inside `MeetingService::transition` via `ObjectService::saveObject()` (per the existing inline comment in `MeetingController` at line 276), so the provider gets the IDOR check for free from the same code path the existing REST API uses. diff --git a/openspec/changes/archive/2026-05-11-decidesk-mcp-tools/proposal.md b/openspec/changes/archive/2026-05-11-decidesk-mcp-tools/proposal.md new file mode 100644 index 00000000..e58dc0e6 --- /dev/null +++ b/openspec/changes/archive/2026-05-11-decidesk-mcp-tools/proposal.md @@ -0,0 +1,98 @@ +--- +kind: code +depends_on: [ai-chat-companion-orchestrator] +--- + +# Decidesk — MCP Tools Provider (first per-app exemplar) + +## Why + +Hydra ADR-034 introduces an AI Chat Companion that exposes per-app MCP (Model Context +Protocol) tools through an OpenRegister-owned orchestrator.

Each must verify the underlying + service mutation method (e.g. `MeetingService::transition`) is NEVER called. + **Acceptance:** all 3 tests pass; mock assertions confirm no service mutation. +- [x] 5.7 Add `testStartMeeting_alreadyInProgress_returnsInvalidState`. Set up a + meeting fixture in `in-progress` state, caller is the chair. Assert the result is + `{isError: true, error: 'invalid_state', message: contains 'in progress'}`. + **Acceptance:** test passes. +- [x] 5.8 Add `testSourcesTruncationAtCap`. Configure `ObjectService` mock so + `decidesk.getMeetingDetails` would produce 35 sources. Assert the returned + `sources` length equals 20, `sourcesTruncated === true`, and + `sourcesTotalCount === 35`. + **Acceptance:** test passes. +- [x] 5.9 Add `testNotFoundReturnsNotFoundEnvelope`. Configure `ObjectService` mock to + return null for the UUID `00000000-0000-0000-0000-000000000000`.

Integration test + +- [x] 6.1 Create `tests/Integration/Mcp/DecideskToolProviderIntegrationTest.php`. Skip + the whole test class with `markTestSkipped` when + `class_exists(\OCA\OpenRegister\Mcp\McpToolsService::class) === false` so it runs + only where the real openregister runtime is installed. + **Acceptance:** test class is registered with PHPUnit; skip works in environments + without openregister. +- [x] 6.2 Inside `setUp`, resolve the provider from the real DI container: + `\OC::$server->query('OCA\\OpenRegister\\Mcp\\IMcpToolProvider::decidesk')`. Assert + it returns an instance of `DecideskToolProvider`. + **Acceptance:** assertion passes when openregister is present (skipped in dev + environments lacking openregister). +- [ ] 6.3 Create a real Meeting fixture in `scheduled` state with a known chair user; + log in as that chair; invoke `decidesk.startMeeting`. Assert (a) the result is + success, (b) the meeting object now reads `in-progress` from a fresh lookup, (c) the + `sources` array has exactly one descriptor with the correct deep link. + **Acceptance:** end-to-end round-trip passes (requires full Nextcloud + OR runtime). + +## 7. Quality gates + +- [x] 7.1 Run `composer phpcs`. Fix any new PHPCS warnings introduced by this change. + Do not modify existing baselines. + **Acceptance:** PHPCS exits 0 for `lib/Mcp/` and `tests/Unit/Mcp/` (and any modified + existing files). +- [x] 7.2 Run `composer phpmd`. Fix any new PHPMD findings (or add an explicit + baseline entry only if the finding is a known false positive — note the rationale in + the baseline). + **Acceptance:** PHPMD reports zero new findings. +- [x] 7.3 Run `composer psalm`. Fix any new Psalm errors at level baseline. + **Acceptance:** Psalm exits 0. +- [x] 7.4 Run `composer phpstan`.
