An MCP server that interfaces with the HackMD API to expose notes, teams, user profiles, and reading history to LLM clients. It supports CRUD operations on individual and team notes, allows listing and managing teams, and retrieving user profile and reading history data. The server provides dual transport options: HTTP transport for cloud deployment and STDIO transport for local client integration. It is designed to be cloud-deployment ready (e.g., Smithery) and runs on Node.js 18+. Configuration is via environment variables (HACKMD_API_TOKEN and HACKMD_API_URL) or HTTP headers when using HTTP transport. Security considerations include protecting tokens and an optional ALLOWED_HACKMD_API_URLS list to restrict endpoints. The project includes tools such as get_user_info, list_teams, get_history, list_team_notes, create_team_note, update_team_note, delete_team_note, list_user_notes, get_note, create_note, update_note, and delete_note. It also provides debugging with the MCP Inspector, Docker images, local development instructions, and MCP Bundle packaging. This server is intended for developers building AI-assisted workflows that rely on HackMD data and collaboration features via MCP.
