A public MCP endpoint that lets an assistant search the blog, browse its catalog, and retrieve complete articles.

Recorded demonstration. Unmute the player to listen.

What it does

Connect an MCP client to https://thelatentsource.com/mcp. It exposes three read-only tools: search_articles, list_articles, and get_article.

The narrated demonstration records a real client session: initialization, tool discovery, article search and retrieval, and an intentional missing-article error. The saved JSON contains the requests and responses.

How it is built

The technical post explains the JSON-RPC transport, tool contracts, shared search and Markdown services, error handling, and the test isolation bug behind the build.
