A local MCP server that fetches official library documentation (llms.txt-first), caches it to disk, and serves relevant sections to coding agents offline with deterministic retrieval.
Enables coding agents to pull official library documentation from its source, cache it to local disk with a TTL, and serve the sections most relevant to a query — working offline from the cached copy when the network is unavailable. It keeps documentation retrieval local and deterministic, avoiding cloud doc services and recurring costs.
