What mcp does

This server links your AI client to Contraption Company essays indexed inside Chroma Cloud. It exposes three core tools: search to run text queries across articles, list_posts to paginate through items, and fetch to retrieve full markdown content by canonical URL.

Users can connect instantly to the public hosted instance at https://mcp.contraption.co without authentication. For local deployments via Python or Docker, you need a Ghost Admin API key, Chroma Cloud database credentials, and a Voyage API key for embeddings.

Query logging and members-only indexing stay active by default.

What it helps with

  • search blog posts and pages using text queries
  • retrieve complete article text via its canonical identifier
  • paginate through published blog posts in chat
  • sync updated or newly published Ghost articles every 5 minutes

Example prompts for the agent

  • Find blog articles about agents using search
  • List recent publications with list_posts
  • Fetch the full content of an essay using fetch
