What is the Coalent MCP server?

Fresh, attributed facts from your sources — cached, and invalidated the moment a source changes.

How to install Coalent

Copy-paste configuration for popular MCP clients.

transport: stdio

Config generated by PluginBench — verify against the source before use.

Environment / auth

OPENAI_API_KEY
required
secret
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.
COALENT_MCP_TOKEN
secret
Optional shared secret for --transport http: when set, every HTTP request must carry Authorization: Bearer <token>. Unused over stdio.
