Overview

What is mcp-obsidian?

mcp-obsidian is a Model Context Protocol (MCP) server that connects AI assistants to the Obsidian Local REST API, enabling programmatic access to Obsidian notes via a Docker container or local TypeScript runtime.

How to use mcp-obsidian?

Configure the server in your MCP client’s JSON settings with required environment variables (API_KEY, API_HOST, API_PORT). The recommended deployment is via Docker using the image ghcr.io/oleksandrkucherenko/obsidian-mcp:latest. For local development, run bun run src/index.ts with the appropriate config.

Key features of mcp-obsidian

  • Dockerized deployment with automatic container cleanup (--rm).
  • Supports WSL2 and Windows host connectivity.
  • Debug logging via DEBUG=mcp:* environment variable.
  • Works with the Obsidian Local REST API plugin (v3.2.0).
  • Pre‑built Docker images for both the MCP server and a full Obsidian‑with‑VNC container.
  • Cross‑platform compatibility (macOS, Linux, Windows/WSL2).

Use cases of mcp-obsidian

  • Integrate Obsidian note‑taking with AI‑powered tools (e.g., Claude Desktop, Windsurf).
  • Automate note creation, search, and content retrieval via MCP.
  • Test MCP interactions locally without a live Obsidian instance (using the Dockerized Obsidian‑VNC image).
