Thoth

- Read-only by design.Writes are structurally impossible — there is noexecutepath that ever mutates data.
- Defense in depth.SQL is validated three ways (SELECT enforcement → injection detection → automatic LIMIT). Redis commands are restricted to an explicit allowlist.
- Secrets never leave your config.Passwords are loaded from env vars and stripped from logs and error messages.
- One server, many datasources.Connect to all your databases through a single MCP endpoint.
- Works with any MCP client— Claude Code, Cursor, Windsurf, and anything else that speaks MCP.

- Query multiple MySQL, PostgreSQL, and Redis instances through one server
- Three-layer SQL safety (SELECT enforcement + injection detection + automatic LIMIT)
- Redis command allowlist (only explicitly safe read-only commands)
- Markdown output for efficient AI context usage
- stdio, SSE, and streamable-http transports
- Docker Compose stack with seed data for local development

- Python 3.10+
- Docker and Docker Compose (optional, for containerized deployment)

SSE mode exposes/sse(client connections) and/messages/(POST endpoint).

When serving over HTTP transports (streamable-httporsse) youshouldsetTHOTH_API_TOKENto protect the server. With a token set, every MCP request must carry anAuthorization: Bearer <token>header; requests without a valid token are rejected with401 Unauthorized. The/healthendpoint is always open for monitoring probes.

# On the server export THOTH_API_TOKEN=$(openssl rand -hex 32) # generate a strong token export MCP_TRANSPORT=streamable-http export MCP_PORT=8080 python -m thoth_mcp

# On the client (curl) curl -H "Authorization: Bearer <token>" http://server:8080/mcp

WhenTHOTH_API_TOKENis unset, authentication is disabled — suitable for localstdiousage, butnever expose an unauthenticated HTTP instance to the public internet.
