Creating and Implementing an MCP Server in Elixir

The authors describe their journey in building an MCP server that allows users to create TIL posts within their AI tooling environments. They explain the purpose of an MCP server, which is to facilitate the interaction between AI tools and their application by providing an API for fetching data and performing actions. They detail the setup process, including the choice of libraries, the creation of various components for managing TIL posts, and the integration of channel listings for better organization. The article highlights challenges encountered, particularly with documentation and authentication, and provides insights into improving user experience, such as the ability to create draft posts. The authors also emphasize the importance of moderation when relying on AI-generated content, noting that while the server enhances productivity, it requires careful management of the output to ensure quality.
