Notetaker MCP Server

Notetaker MCP Server

The Notetaker MCP Server is a lightweight, purpose‑built tool that lets Claude Desktop users manage their notes directly from the chat interface. By exposing a set of intuitive tools and prompts, it removes the friction of switching between a note‑taking app and an AI conversation. Developers who want to embed persistent, structured memory into their Claude agents can leverage this server to keep a simple text‑based notebook that grows with every interaction.

The core idea is straightforward: a single file lives in the project folder and acts as a serialised ledger of user‑generated notes. Whenever an agent runs the tool, the content—whether typed by the user or generated by Claude—is appended to this file. Retrieval tools (, , ) expose the data back to the LLM, enabling context‑aware follow‑ups. Two dedicated prompts ( and ) let the model summarize or search existing entries, returning both content and index so that subsequent steps can reference the correct note.

For developers building AI workflows, this server offers several tangible benefits. First, it introduces a persistent memory layer that can be queried on demand without storing data in external databases. Second, the tools are designed to integrate seamlessly with Claude’s MCP ecosystem; once installed, they appear as native actions in the chat UI, and resources or prompts can be attached via the developer configuration. Third, because the server is written in Python and uses the MCP SDK, it can be extended or replaced with minimal friction—adding new tools for tagging, categorising, or exporting notes is as simple as adding a function to the file.

Typical use cases include research assistants that compile literature notes, personal productivity bots that track daily reflections, or educational agents that generate study cards. In each scenario, the agent can ask for a summary of past notes or search for specific information, all while keeping the user in a single conversational flow. The lightweight text format also means that notes can be version‑controlled, backed up, or shared across machines without needing a dedicated backend.

What sets the Notetaker MCP Server apart is its zero‑config, no‑friction design. It requires only a single text file and the standard MCP command to launch, making it ideal for rapid prototyping or for teams that want a quick way to add memory capabilities to Claude without setting up complex infrastructure. The server’s explicit tools and prompts provide a clear, predictable interface for developers, while still offering the flexibility to adapt or extend functionality as needed.
