Coalent MCP Server

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

Put your own value in place of <OPENAI_API_KEY> (Required in folder (--watch) mode for semantic embeddings (text-embedding-3-small) and build synthesis (gpt-4o-mini); the server exits loudly without it rather than degrade. Factory (--cache-factory) mode brings its own models and needs no key). The author’s registry entry marks it as required.

Optional settings from the registry entry, left out of the block above: COALENT_MCP_TOKEN (Optional shared secret for --transport http: when set, every HTTP request must carry Authorization: Bearer <token>. Unused over stdio).
