Streamable HTTP, OAuth 2.1, capability auth. ## Tools Capabilities this server exposes over MCP: - **daily_lunch_menu** — show the school's lunch menu, with optional date or month. - **wallet_balance** — report the current spendable wallet balance and remind the user that top-up happens in the Paxaver panel. - **upcoming_events** — list upcoming school events and offer registration or volunteer sign-up. - **lunch_order_helper** — guide a user through selecting a student, reviewing a lunch order draft, and confirming payment. It accepts an optional `student_name` argument. ## Claude Desktop Quick Installation Remote MCP endpoint (confidence: high). Install path detected from listing signals. Add as a URL/SSE server in your client: ```json "mcpServers": { "paxaver-mcp": { "url": "http://localhost:8787/mcp" } } ``` ## Documentation & README # Paxaver MCP Server > AI-facing adapter over the [Paxaver](https://paxaver.com) school community platform. > Implements the Model Context Protocol (MCP) on Cloudflare Workers with RS256 JWT > validation, capability-first authorization, and Streamable HTTP transport.

It is a **thin adapter**. It contains no business logic and holds no database, payment, or email credentials. Every action runs against the Paxaver backend API as the authenticated user, and errors are sanitized before they reach the client. --- ## Connect Point an MCP-compatible client at the hosted endpoint and sign in with a Paxaver account when prompted (OAuth 2.1 Authorization Code + PKCE): ```text https://mcp.paxaver.com/mcp ``` The server speaks MCP protocol `2025-06-18` over Streamable HTTP (`POST /mcp`). One endpoint serves all regions; the user's region is resolved from their account at sign-in. --- ## Install ```bash npm install @paxaver/mcp ``` The package ships the Worker source for self-hosting and development. Most users only need the hosted endpoint above. ### Run locally ```bash pnpm install # Node >= 26.8.2, pnpm >= 10 pnpm dev # Miniflare on http://localhost:8787 — MCP endpoint: POST /mcp ``` ### Docker ```bash docker build -t paxaver-mcp . docker run -p 8787:8787 paxaver-mcp # MCP endpoint: http://localhost:8787/mcp ``` Self-hosted and local instances perform no token-revocation check: a revoked token stays valid until it expires. Tokens are still verified by signature, expiry, and a live user-context load. See [CONTRIBUTING.md](https://github.com/Smartoire/paxaver-mcp/blob/HEAD/CONTRIBUTING.md) for the full development setup. --- ## Tools The server exposes 37 tools grouped into six categories. Visibility in `tools/list` is filtered by the caller's roles; every call is re-authorized before dispatch, and the backend re-checks data-level access (defense-in-depth). | Category | Tools | | ----------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | User / wallet | `get_my_context`, `sign_out`, `get_my_wallet_balance`, `list_my_wallet_transactions` | | Lunch ordering | `get_lunch_menu`, `list_my_lunch_orders`, `create_lunch_order_draft`, `update_lunch_order_draft`, `discard_lunch_order_draft`, `pay_lunch_order_draft`, `cancel_my_lunch_order` | | Events & volunteering | `list_school_events`, `get_school_event`, `register_for_event`, `list_my_event_registrations`, `cancel_my_event_registration`, `list_my_volunteer_signups`, `sign_up_for_volunteer_shift`, `cancel_my_volunteer_signup` | | Event administration | `create_school_event`, `update_school_event`, `cancel_school_event`, `list_event_attendees`, `check_in_event_ticket`, `create_volunteer_shift` | | Programs | `list_school_programs`, `register_for_program`, `cancel_program_registration`, `list_program_registrations`, `admit_program_registration` | | Restaurant / menu admin | `list_school_restaurants`, `create_school_restaurant`, `list_restaurant_menu_items`, `create_restaurant_menu_item`, `update_restaurant_menu_item`, `archive_restaurant_menu_item`, `schedule_lunch_menu_item` | ### Prompts The server registers four prompts: `daily_lunch_menu`, `wallet_balance`, `upcoming_events`, and `lunch_order_helper` (optional `student_name` argument). Availability and content are returned by `prompts/list` and `prompts/get`. Ordering is draft → review → payment: `create_lunch_order_draft`, adjust with `update_lunch_order_draft`, then `pay_lunch_order_draft`. `sign_out` ends the caller's sign-in for this MCP connection: the next request gets the usual sign-in challenge. An app that holds its own Paxaver credentials cannot be signed out this way — the result directs the user to disconnect Paxaver in that app or in their Paxaver account settings instead. Pre-2.5 tool names still resolve to the canonical tools but are no longer advertised; the retired `order_lunch` tool is removed. Financial and destructive tools are labeled and require user confirmation. ### Privacy The only contact information returned through MCP tools is the caller's own sign-in email — `get_my_context` includes it so a client can answer "which login am I on?", and `sign_out` names the account it signs out. Phone, address, and other contact fields are never returned. Student data is limited to IDs, names, and school slugs; allergies, notes, birthday, and other PII are not exposed in read responses. The MCP server does not log user data. --- ## Documentation | Document | Topic | | ------------------------------------ | ------------------------------------------ | | [CHANGELOG.md](https://github.com/Smartoire/paxaver-mcp/blob/HEAD/CHANGELOG.md) | Release history | | [SECURITY.md](https://github.com/Smartoire/paxaver-mcp/blob/HEAD/SECURITY.md) | Vulnerability reporting policy | | [CONTRIBUTING.md](https://github.com/Smartoire/paxaver-mcp/blob/HEAD/CONTRIBUTING.md) | Development setup and contribution process | Internal documentation (architecture, authentication, authorization, full tool reference, deployment, security model, test scenarios) lives in the private Paxaver monorepo under `docs/paxaver-mcp/` and is intentionally not published. --- ## Tech stack - **Runtime:** Cloudflare Workers - **Framework:** [Hono](https://hono.dev) v4 - **JWT:** [jose](https://github.com/panva/jose) v6 (RS256 via JWKS) - **Protocol:** MCP `2025-06-18`, Streamable HTTP - **Build/deploy:** [Wrangler](https://developers.cloudflare.com/workers/wrangler/) v4 - **Test:** [Vitest](https://vitest.dev) v5 (Workers pool + Node pool) --- ## Support - Bug reports and feature requests: [GitHub issues](https://github.com/Smartoire/paxaver-mcp/issues) - Security reports: see [SECURITY.md](https://github.com/Smartoire/paxaver-mcp/blob/HEAD/SECURITY.md) ## License Apache-2.0.
