Joplin

Joplin-MCP-Server provides a bridge between Claude and the Joplin note-taking application's API, enabling AI assistants to interact with notebooks and notes directly within conversations. Built by Kevin Fischer, this Ruby implementation authenticates with Joplin using environment variables for port and token, and currently offers a tool to retrieve and display the complete notebook hierarchy in a formatted tree structure. The server leverages the HTTParty gem for API communication and includes comprehensive error handling and pagination support, making it particularly valuable for users who want to reference or manipulate their Joplin notes without leaving their conversation interface.
