Platform Market: Build an MCP server with Air Pipe and Postgres
A step-by-step technical guide showing how to build an MCP (model-calling protocol) server using Air Pipe and a Postgres database. The tutorial provides a schema (mcp_tenants, mcp_tokens, mcp_tasks), a single-file Air Pipe config exposing MCP tools (list_tasks, create_task), deployment instructions (managed or self-hosted), token minting (HS256 / SOLO_SECRET), verification via curl, and instructions to point MCP clients (e.g., Claude Desktop, Claude Code, Cursor) at the endpoint. It also covers multi-tenant token exchange, runtime revocation using a jti denylist, gating tool discovery with list_authorizer, observability (Prometheus/OpenTelemetry traces), known limitations, and links to ready-made packs (MCP Postgres Starter, MCP Quickstart).
Practical technical guide enabling secure LLM tool integration and multi-tenant MCP deployments; useful for engineers but not industry-shifting.
Key Takeaways & Evidence Grounding
- Air Pipe provides a pack and config pattern to expose MCP tools over Postgres.
- The tutorial defines three Postgres tables: mcp_tenants, mcp_tokens (revocation denylist), and mcp_tasks.
- MCP clients referenced include Claude Desktop, Claude Code, and Cursor.
- Tool discovery (tools/list) is unauthenticated by default and can be gated using a list_authorizer interface.
- The guide documents per-tenant tokens, token revocation via the mcp_tokens table, and OIDC/JWKS verification for Auth0/Clerk/Cognito providers.
