911CPB-MCP

A hosted, read-only MCP server that lets Claude explore and query the CRM Postgres database.

Hosted on Cloudflare

Runs as a Cloudflare Worker. MCP (Streamable HTTP) at /mcp, plus a REST API with an OpenAPI spec for agents without MCP.

Read-only by design

One statement per call, read-type statements only, inside a READ ONLY transaction, against the Aurora reader endpoint.

Pooled via Hyperdrive

Cloudflare Hyperdrive holds the credentials and pools connections to Aurora in us-east-2.

OAuth or access key

Sign in with OAuth 2.1 (claude.ai, ChatGPT) or send the access key as Authorization: Bearer / X-API-Key. Anything else gets a 401.

Works with any agent

Cursor, VS Code, Windsurf, Gemini CLI, Codex, OpenAI, LangChain, custom GPTs. See Connect any agent. Agent-readable docs are at /llms-full.txt.
