What is the Simplenote MCP server?

Connect Simplenote to Claude, Cursor or any other MCP client and it stops being a tab you switch to. MCP evaluations for Simplenote MCP Server. The simplenote mcp server is what makes that connection.

What the server does

This allows Claude Desktop to interact with your Simplenote notes as a memory backend or content source.

Installation

@smithery/cli on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

  • create_note — Create a new note
  • update_note — Replace full note content (destructive)
  • delete_note — Soft-delete: move note to Trash
  • restore_note — Untrash a note — move it back from Trash
  • permanent_delete_note — Irreversibly destroy a single note (requires confirm=true)
  • empty_trash — Permanently delete all trashed notes (dry-run by default)
  • get_note — Get a note by ID with full content and metadata
  • add_text — Append or prepend text without overwriting
  • search_notes — Full-text search with filters and pagination
  • add_tags — Add tags to a note
  • remove_tags — Remove specific tags from a note
  • replace_tags — Replace all tags on a note

Credentials and setup notes

Configuration is passed through the environment: SIMPLENOTE_EMAIL, SIMPLENOTE_PASSWORD, CACHE_MAX_SIZE, MCP_HTTP_HOST, MCP_HTTP_AUTH_TOKEN. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

  • Simplenote account (create one at simplenote.com) - Python 3.10+ (for non-Docker installs) or Docker

Worth knowing first

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • With 14 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Simplenote.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Where it fits

Among the planning and project tracking options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Simplenote's toolset — create_note, update_note, delete_note and 11 more — is a fair guide to whether it matches your workflow. It is maintained by docdyhr; worth a glance at recent repository activity before you build anything load-bearing on it.
