Simplenote Mcp
Connects Claude and other MCP clients to your Simplenote account with read access by default and optional write tools (create, update, trash, restore). On macOS it can read directly from the Simplenote desktop app's local Core Data store with zero auth, fully offline. On Linux, Windows, or macOS without the app, it authenticates once via magic link and talks to the Simperium HTTP API. Setup asks whether to enable write mode, which gates the mutation tools behind explicit opt-in. Useful when you keep research notes, drafts, or reference material in Simplenote and want Claude to search or update them without switching apps.

revert_noteRestore a note to a prior version. Counts toward the write-rate budget. Bypasses the trashed-note guard — reverting to a non-trashed version will un-trash; reverting to a trashed version will re-trash.

simplenote-mcp
An MCP (Model Context Protocol) server that gives any MCP-compatible AI tool access to your Simplenote data — read by default, with opt-in write tools (create, update, trash, restore, revert) when you run simplenote-mcp setup with write mode enabled.
On macOS, it can read directly from the local Simplenote desktop app's Core Data store — fully offline, no auth. On Linux and Windows (and on macOS without the desktop app), it talks to the Simperium HTTP API after a one-time simplenote-mcp setup.
Works with Claude Desktop, Claude Code, Cursor, VS Code (Copilot), Zed, Cline, Windsurf, and anything else that speaks MCP.
Quick start
Run setup once:
npx -y @automattic/simplenote-mcp setup
On macOS with the Simplenote desktop app installed and synced, setup detects the local database and asks whether to use it. Accepting that option is fully offline and read-only. On Linux, Windows, or macOS without the desktop app, setup opens Simplenote's login page in your browser. After you log in, the page shows a one-time code; paste it into setup, then choose whether to enable write mode.
