Add MCP server (claude.ai custom connector for Ollert) - #31
Conversation
Decided approach for exposing Ollert's REST API as MCP tools: a separate mcp/ service (Bun + Hono + official MCP TS SDK) that's a thin client of the existing API, with Supabase's native OAuth 2.1 server acting as the Authorization Server so mcp/ stays a pure Resource Server. Design, open risks, and implementation order written up in planning/mcp-server.md. No implementation yet.
mcp/: thin Bun/TS client of the CakePHP REST API — pure OAuth 2.1 resource server validating Supabase JWTs (same JWKS api/'s AuthMiddleware verifies), publishing RFC 9728 metadata pointing claude.ai at Supabase's authorization server, forwarding the caller's Bearer unchanged. 18 tools 1:1 with api-contract.md. Built on @modelcontextprotocol/server v2.0.0 — registerTool, createMcpHandler (web-standard fetch, no Hono), SDK auth helpers (requireBearerAuth/oauthMetadataResponse); zod 4 for the standard-schema jsonSchema converter the SDK's inputSchema requires. web/src/routes/oauth/consent.tsx: consent screen for Supabase's OAuth server (public route — reached before a session is guaranteed). Inline sign-in when no session (reuses auth components + useAuth), supabase.auth.oauth getAuthorizationDetails/approveAuthorization/denyAuthorization with skipBrowserRedirect:true → data.redirect_url (avoids the redirect_to docs footgun, supabase#45006). config/deploy.mcp.yml: Kamal deploy for the mcp container on the shared kamal-proxy (negrita, ollert-mcp.2719.fyi, host-routed like api/web). planning/mcp-server.md + log.md: design doc synced to what shipped (SDK API, no Hono, zod 4, steps 1-4 done); Supabase OAuth server enabled, public-client OAuth app registered (DCR off, PKCE-only, redirect to claude.ai callback).
…-end Deploy fix: move the /health liveness route before the hostHeaderValidationResponse DNS-rebinding guard in mcp/src/server.ts. kamal-proxy healthchecks the container by docker-internal hostname, whose Host header isn't in allowedHostnames -> 403, failing the deploy healthcheck despite the app booting fine. /health returns only ok, so exempting it is safe (mirrors api's nginx-static-health bypass). Planning/log: 2026-08-24 entry — mcp deployed to ollert-mcp.2719.fyi behind the shared kamal-proxy, web SPA redeployed to pick up the /oauth/consent route, and the real claude.ai <-> Supabase connector dance verified. Settles the last open risk: aud claim on OAuth-flow tokens matches SUPABASE_JWT_AUD=authenticated, no widening needed. mcp-server.md: open risks updated (aud verified, AS server enabled), implementation step 6 marked done, deployment paragraph updated. CLAUDE.md: two learnings recorded (health-route-before-host-guard, stale-deployed-SPA 404 on a route that exists locally).

In `@mcp/Dockerfile`:
- Around line 21-22: Update the Dockerfile to create or reuse a non-root service
account, ensure the application files are owned and accessible by that account,
and set USER to the account before the existing CMD instruction.
- Line 15: Update the Dockerfile dependency installation step to copy both
package.json and the committed bun.lock before bun install, then run the
installation with --frozen-lockfile so dependency resolution remains locked.
Apply the same fix in `@mcp/package.json` at line 15: The unpinned runtime
dependency is part of the same reproducible-build issue.
In `@mcp/src/server.ts`:
- Around line 61-66: The metadata fetch in buildHandler must have a bounded
timeout so startup cannot stall; pass an AbortSignal.timeout value to fetch and
ensure a timeout or other fetch failure is handled as a startup failure before
parsing OAuthMetadata, preserving the existing error-exit behavior.
In `@mcp/src/tools/cards.ts`:
- Line 50: Constrain every interpolated resource identifier to UUIDs using one
shared z.string().uuid() schema, then wrap each validated path value with
encodeURIComponent before URL construction. Apply this across the card
operations in mcp/src/tools/cards.ts at lines 50-50, org operations in

operations in mcp/src/tools/lists.ts at lines 17-39.
In `@planning/log.md`:
- Around line 60-61: Reorder the two change-log bullets so the Supabase OAuth
server and consent route entry precedes the MCP deployment and end-to-end
verification entry, preserving a consistent progression from implementation to
deployment and verification.
In `@planning/mcp-server.md`:
- Line 12: Update the status language in the MCP architecture document to
describe the service as implemented and shipped: remove “Not yet built” and
revise the references around deployment, OAuth verification, and previously
unresolved or undecided work so they consistently reflect the completed
implementation, without changing the documented design.
- Around line 24-26: Update both documented JWT claim lists—near the
Bearer-token validation description and the directory-layout note—to include the
required email claim alongside sub, matching verifyAccessToken’s validation
contract.

- Resource-identifier tool inputs (id/org_id/board_id/list_id/user_id) tightened from z.string().min(1) to z.string().uuid(). min(1) accepted '../<org-id>' which URL-normalized to a different authorized route (path-traversal across resources). Free-text fields stay .min(1)/.optional. - Dockerfile: --frozen-lockfile against committed bun.lock for reproducible image builds; run as a non-root user (useradd mcp + USER mcp). - server.ts: bound the startup AS-metadata fetch with a 5s AbortSignal.timeout so a stalled request can't hang the server (no /health) before Bun.serve starts; fail fast on the catch as on !res.ok. - planning/log.md + planning/mcp-server.md: stale-status fixes (MCP built and deployed, aud verified, consent route built, step 5 superseded) and email added to both required-claim lists since verifyToken rejects a token missing sub OR email.
PR-Agent's PR #31 run failed: gemma 429'd, fell back to nemotron, which returned YAML wrapped in markdown fences AND duplicated -> load_yaml returned None -> pr_reviewer.py TypeError on None. retry_with_fallback_models only retries API-level failures (429/timeout/5xx), NOT a 200 with unparseable content, so the third fallback (GLM-5.2) was never tried. With propagate_tool_errors=true the parse failure crashed the whole step. Fix: GLM-5.2 (strongest instruction-follower of the three free options tried, reliably returns raw YAML) as primary model; gemma + nemotron demoted to API-level fallback_models only. Set in both .github/workflows/pr_agent.yml and .pr_agent.toml. PR_AGENT_SETUP.md: new gotcha section on the model-quality/parse-failure failure mode (free-tier models fence-wrap/duplicate YAML; parse failures aren't retried; GLM-5.2 primary recommendation).
KAMAL_DEPLOYMENT.md §6: add a third fix option for the healthcheck-Host- header trap — the app-level host-guard variant. When the Host-header guard lives in the app's own fetch handler (MCP SDK's hostHeaderValidationResponse) rather than middleware, there's no middleware layer to whitelist /health into; instead handle /health before invoking the guard. Mirrors the static- webroot pattern, just in-process. See mcp/src/server.ts. CLAUDE.md: meta-note under the Living-document paragraph that KAMAL_DEPLOYMENT.md and PR_AGENT_SETUP.md are living runbooks to keep current when a new kamal/pr-agent gotcha is hit, not just the Learnings list.

PR-Agent retry_with_fallback_models load_yaml try_fix_yaml fallback only API errors source
💡 Result:
In CodiumAI's PR-Agent, the functions retry_with_fallback_models and load_yaml (often assisted by try_fix_yaml) are key components of a multi-layered strategy to handle API errors and malformed model outputs [1][2]. retry_with_fallback_models is used to manage model reliability [2]. When an initial LLM request fails—often due to API errors or rate limits—this function iterates through a list of configured fallback models (defined in the project settings) until it achieves a successful generation [2][3]. This mechanism is widely implemented across core tools like pr_code_suggestions, pr_reviewer, and pr_description to ensure robustness [4][3][5][6]. load_yaml acts as the primary entry point for parsing AI-generated text into a dictionary [1][7]. If the initial YAML parsing fails, it invokes try_fix_yaml to attempt a series of recovery strategies [1][7]. These fallbacks are designed to address common LLM output issues, such as: 1. Improper formatting: Attempting to add pipe operators (|- or |) or adjusting indentation for block scalars [7][8]. 2. Code block extraction: Using regex to locate and extract valid YAML content from within larger, sometimes malformed, response blocks (e.g., handling yaml, yml, or untagged ``` fences) [1][7][9]. 3. Key-based extraction: Supporting parameters like first_key and last_key to help isolate specific YAML segments within a response, which is particularly useful for tools like pr_code_suggestions [10][4]. These layers act as a defensive system: retry_with_fallback_models attempts to overcome provider-level API failures, while load_yaml and try_fix_yaml address content-level parsing failures caused by the model itself [11][2][8]. If all fallbacks are exhausted without a valid result, the process typically logs an error and defaults to a safe, empty state [1][11][4][5].

OpenRouter documentation free models rate limits free endpoints
💡 Result:
On OpenRouter, free models—denoted by the:free suffix in the model ID (e.g., meta-llama/llama-3.2-3b-instruct:free)—are subject to specific platform-level rate limits [1][2][3]. These limits are determined by the total amount of credits purchased on your account [2][4][5]. Rate limits for free models: - If you have purchased less than $10 in credits: You are limited to 50 requests per day [5]. - If you have purchased at least $10 in credits: Your daily limit increases to 1,000 requests per day [5]. - Requests per minute: Regardless of credit status, free model variants are generally capped at 20 requests per minute [5]. Key considerations: - Usage Tracking: Failed attempts count toward your daily quota [5]. - Global Capacity: Rate limits are governed globally; creating multiple API keys or accounts will not bypass these restrictions [1][2]. - Free Models Router: You can use the special model ID openrouter/free to have OpenRouter automatically select an available free model for your request [4][6]. - Errors: When you exceed these limits, the API will return a 429 Too Many Requests error [2][5]. It is recommended to implement exponential backoff and honor the Retry-After header when present [2]. - Production Use: Because of these low caps, free models are generally not considered suitable for production applications [4][6]. For users needing higher limits, you can switch to the paid version of a model (if available), which is not subject to these platform-level request caps, or utilize Bring Your Own Key (BYOK) if supported, which allows you to manage rate limits directly with the upstream provider [2][5][6].

Qualify the model-reliability claims in all three locations.
retry_with_fallback_models cannot handle parse failures that occur after the generation call returns. load_yaml supports a single fenced YAML block, but malformed or duplicated output can still produce None and raise TypeError. OpenRouter also rate-limits :free variants, so GLM-5.2 cannot guarantee raw YAML or avoid 429 responses. Keep the model ordering, but describe GLM-5.2 as an observed mitigation in .github/workflows/pr_agent.yml, .pr_agent.toml, and PR_AGENT_SETUP.md.

| Supabase Auth now ships a native OAuth 2.1 + OIDC authorization server built specifically for MCP use cases (public beta since Nov 2025), issuing access tokens signed with the **same JWKS/keys** as normal Supabase login JWTs — the ones `api/src/Middleware/AuthMiddleware.php` already verifies (see [Architecture § Auth Flow](architecture.md#auth-flow)). This means `mcp/` never issues, stores, or refreshes tokens itself: | ||
|
|
||
| * It validates every incoming Bearer token against Supabase's JWKS, mirroring `AuthMiddleware.php`'s checks (RS256 signature, `iss`, `aud`, `exp`, `sub`, `email`) — same rules, ported to TypeScript (`jose`), not reinvented. | ||
| * It publishes RFC 9728 protected-resource metadata (`/.well-known/oauth-protected-resource`) pointing claude.ai at Supabase's authorization-server metadata (`https://<project-ref>.supabase.co/.well-known/oauth-authorization-server/auth/v1`) — the actual authorize/token/refresh/dynamic-client-registration dance happens directly between claude.ai and Supabase, never touching `mcp/`. |

@modelcontextprotocol/server oauthMetadataResponse getOAuthProtectedResourceMetadataUrl path-aware metadata route
💡 Result:
In the Model Context Protocol (MCP) TypeScript SDK, getOAuthProtectedResourceMetadataUrl and oauthMetadataResponse are utilities provided by the @modelcontextprotocol/server package to support OAuth discovery, specifically enabling path-aware metadata routes as defined by RFC 9728 [1][2]. getOAuthProtectedResourceMetadataUrl This function constructs the RFC 9728 Protected Resource Metadata URL for a given MCP server URL by prepending /.well-known/oauth-protected-resource to the server's path [1][3]. - Example: For an MCP server at https://api.example.com/mcp, the resulting URL is https://api.example.com/.well-known/oauth-protected-resource/mcp [1][4]. - This URL is used in WWW-Authenticate challenges, allowing unauthenticated clients to discover the authorization server [2][5]. oauthMetadataResponse This utility is a runtime-neutral, web-standard fetch handler used to serve OAuth discovery documents [2][3]. - It manages two well-known routes: 1. /.well-known/oauth-protected-resource[/]: Serves the RFC 9728 Protected Resource Metadata, incorporating the server path (path-aware) [1][3]. 2. /.well-known/oauth-authorization-server: Serves the RFC 8414 Authorization Server Metadata verbatim [1][3]. - It handles GET/HEAD/OPTIONS requests with permissive CORS and returns undefined for unrecognized paths, allowing it to compose as a fall-through middleware in web-standard servers (like those using Request/Response objects) [2][3][5]. These utilities replace the older express-specific mcpAuthMetadataRouter, providing a framework-agnostic way to implement OAuth discovery in MCP servers [2][6].

- mcp/src/apiClient.ts: spread caller-supplied init.headers FIRST so the
verified Authorization/Accept/Content-Type always win. Auth header is a
trust boundary — a caller passing its own Authorization must not clobber
the resource server's bearer. No current call site passes headers
(all use {method, body}), so defensive hardening, not a live bug.

- KAMAL_DEPLOYMENT.md §6: 'Two clean fixes' -> 'Three' (the app-level

- PR_AGENT_SETUP.md gotcha section: fix broken Markdown from adjacent
triple backticks in prose (spelled out 'markdown code fences' instead);
correct the retry mechanism — retry_with_fallback_models guards the API
call itself, but the YAML parse runs AFTER the wrapper returns, so a 200
with an unparseable body never reaches the retry path (was: 'only
retries on API-level failures' — wrong mechanism, right outcome).

Add a bounded timeout to the API call and response-body read.
apiFetch has no default signal, and all 16 MCP tool calls omit one. If the API stalls before headers or while res.text() consumes the body, the tool can remain pending. Add a configured timeout, combine it with init.signal, and use the combined signal for both operations.

headers or during response-body consumption.
User description
What
Adds
mcp/— a new top-level service (sibling toapi/andweb/) that exposes Ollert's REST API as MCP tools so claude.ai's hosted custom connector can manage a user's boards/lists/cards on their behalf. Thin Node/TS (Bun) client of the existing CakePHP API — no business logic, authorization, or quotas reimplemented.Also adds the one
web/route the OAuth flow needs (/oauth/consent) and the Kamal deploy config (config/deploy.mcp.yml).How it works
mcp/never issues, stores, or refreshes tokens. It validates every incoming Bearer token against Supabase's JWKS (portingAuthMiddleware.php's iss/aud/sub/exp checks 1:1 tojose), publishes RFC 9728 protected-resource metadata pointing claude.ai at Supabase's own authorization server, and forwards the caller's Bearer token unchanged toapi/on every tool call. The authorize/token/refresh dance happens directly between claude.ai and Supabase.@modelcontextprotocol/serverv2.0.0, streamable-HTTP transport. Tools register viaMcpServer.registerTool;createMcpHandler(factory, { legacy: "stateless" })returns a web-standard{ fetch }handlerBun.servemounts directly — no Hono, no node-server adapter. SDK auth helpers (requireBearerAuth,oauthMetadataResponse,hostHeaderValidationResponse) replace hand-rolled auth files.planning/api-contract.md:list_orgs,create_org,get_org,update_org,delete_org,list_org_members,add_org_member,remove_org_member,list_org_boards,create_board,get_board,update_board,delete_board,create_list,update_list,delete_list,create_card,update_card,delete_card.web/src/routes/oauth/consent.tsx— Supabase's OAuth server doesn't host a consent screen, so the SPA builds it: readsauthorization_id, inline sign-in when no session (reuses auth components), renders the requesting client + scopes, callssupabase.auth.oauth.approveAuthorization/denyAuthorizationwithskipBrowserRedirect, bounces todata.redirect_url.Deployed & verified end-to-end

https://ollert-mcp.2719.fyibehind the shared kamal-proxy on negrita (distinct Host-routed vhost, same as api/web). The real claude.ai↔Supabase connector dance was run and connects cleanly — settling the last open risk: theaudclaim on OAuth-flow-issued Supabase tokens matchesSUPABASE_JWT_AUD=authenticated, no audience-widening needed inverifyToken.ts.One deploy fix landed here:
