Markdown Notes MCP Server

This project provides a simple MCP (Model Context Protocol) server for managing markdown notes. It's built using the fastmcp library.

Prerequisites

• Python 3.10 or newer

• uv package manager

Installation

1. Install

   This project uses uv for dependency management. Running the command below will install fastmcp and any other dependencies listed in pyproject.toml.

   uv pip install fastmcp

Configuration

The server's behavior can be customized via the following environment variable:

• MD_NOTES_PATH: Specifies the root directory for all note-related operations. If this variable is not set, the server will default to using the current working directory. Both the list_notes and read_note tools will resolve file and directory paths relative to this base path.

Running the Server

You can run the server in two modes: run for production/consumption and dev for development and testing.

Run Mode

This mode is for running the server to be used by the Gemini CLI. The main.py script can now be run directly as it contains the server startup logic.

python main.py

You should see output similar to this:

[12/13/25 17:52:18] INFO     Starting MCP server 'MarkdownNotes' with transport 'http'  server.py:2582
                             on http://127.0.0.1:8080/mcp
INFO:     Started server process [24263]
INFO:     Waiting for application startup.
INFO:     Application startup complete.
INFO:     Uvicorn running on http://127.0.0.1:8080 (Press CTRL+C to quit)

Dev Mode

This mode starts the MCP Inspector, a web application that allows interactive testing of the tools provided by the MCP server.

fastmcp dev main.py --ui-port="9080" --server-port="5080"

You will see output like this, including a URL to access the MCP Inspector:

Starting MCP inspector...
⚙ Proxy server listening on localhost:5080
🔑 Session token: <your_session_token>
   Use this token to authenticate requests or set DANGEROUSLY_OMIT_AUTH=true to disable auth

🚀 MCP Inspector is up and running at:
   http://localhost:9080/?MCP_PROXY_PORT=5080&MCP_PROXY_AUTH_TOKEN=<your_session_token>

Connecting to Gemini CLI

To use this MCP server with the Gemini CLI, you need to add it as a source.

gemini mcp add --transport http mdnotes http://127.0.0.1:8080/mcp

After adding the server, you can use the /mcp command in the Gemini CLI to see the available tools.
