In short
Obsidian MCP is a free, local server enabling AI assistants to safely read and modify configured Obsidian vaults without opening the app.
Obsidian MCP is a local Model Context Protocol server that allows MCP-compatible assistants to safely read and modify explicitly configured Obsidian vaults. The server works directly with Markdown files, so the Obsidian application does not need to be open for it to function. Version 2 of the server supports both MCP 2026-07-28 and 2025-era clients by default and requires Node.js 22 or newer to run.
The vendor says that the server operates locally and never listens on a network interface or sends telemetry. Users can configure up to ten vaults for the server to access. File mutations are journaled, conflict-checked, atomically replaced, and rolled back as a single transaction.
Because MCP clients can invoke destructive tools, the documentation advises users to back up important vaults and review client permission prompts. Legacy protocol and v1 positional-path compatibility are deprecated and print exact migration instructions to stderr.
