Simplenote MCP Server

Simplenote MCP Server is an MCP server that connects Claude Desktop and other Model Context Protocol clients directly to Simplenote. It serves developers, researchers, and writers who use Simplenote for cross-device capture and want to use their notes as an external working memory backend. The server implements 30 tools covering core note lifecycle operations, such as creating, reading, updating, and deleting notes, alongside advanced search supporting boolean logic, phrase matching, and tag filtering. In addition to standard note management, it supports publishing notes to public URLs, managing trash with dry-run confirmation guards, and client-side AES-256-GCM encryption through an opt-in Vault feature to secure note bodies before they leave the client. It also exposes standard MCP resources with tag and pagination metadata, as well as prompt templates designed for cross-session continuity workflows.

What is Simplenote MCP Server?

Simplenote MCP Server is an integration server built with the Model Context Protocol Python SDK. It allows AI clients such as Claude Desktop to read, write, search, and manage notes stored in your Simplenote account.

Which MCP clients work with Simplenote MCP Server?

The server is built specifically for Claude Desktop and also works with any client compatible with the Model Context Protocol standard, connecting via stdio or HTTP transport layers.

What features does Simplenote MCP Server support?

It provides 30 tools covering full note CRUD operations, boolean search, tag filtering, public note publishing, client-side AES-256-GCM note encryption, trash management with confirmation safeguards, and session handoff prompts.

How does note encryption work in Simplenote MCP Server?

Because Simplenote lacks native encryption at rest, the server provides an opt-in Vault system. When enabled, note bodies are encrypted into AES-256-GCM ciphertext on the client before being sent across the Simplenote API.

Is Simplenote MCP Server open source?

Yes, Simplenote MCP Server is open-source software distributed under the MIT license with source code available on GitHub.
