llmmcp — Claude Code MCP server: live LLM API docs for agents
Feeds your agent current model and API details from OpenAI, Anthropic and Google so it stops inventing versions and parameters.
Open on GitHubWhat llmmcp does
llmmcp is an MCP server that hands your coding agent official provider documentation instead of whatever it half-remembers from training. It exposes two tools: search_docs for looking things up in the indexed docs, and list_providers for the current provider and model lineup.
Under the hood a scraper pulls markdown and text from the official sites once a week. Chunks land in Pinecone with integrated embeddings, and a Cloudflare Worker handles embedding and retrieval, caching popular queries in Workers KV. A small CLI turns MCP calls into requests to that Worker. Nothing runs locally: npx -y llmmcp@latest starts it, and Cursor takes it as a command under Settings > Models > MCP Servers while Claude Desktop wants an entry in claude_desktop_config.json.
Queries leave your machine for a hosted backend, so if prompts or internal docs must stay local, sort out self-hosting first. The repo is open source, though the deployment guide is not written yet — the README points at the logs for the current setup.
What it helps with
- check tool use parameters for a specific model
- confirm context window sizes and rate limits
- list a provider's current models without hardcoding them
- steer an agent toward a current library pattern instead of a deprecated one
Example prompts for the agent
- Look up the tool use parameters for Gemini 1.5 Pro in the docs
- Which Anthropic models are current right now?
- Check the official docs for how to set rate limits
