NoteLLM_MCP_Server

NoteLLM_MCP_Server is an open-source software designed to provide MCP services via API for the Joplin plugin NoteLLM.

It can also serve as a general-purpose MCP service provider through API, or offer standard MCP access via stdio, SSE, or streamableHTTP.

Features

Compatible with Various MCP Tool Integrations: Supports adding MCP tools through standard JSON files, making tool integration straightforward and intuitive.
API-Based MCP Service Mode: Built on the FastAPI framework, it provides API endpoints for invoking MCP services, enabling efficient and convenient integration and usage.
Multiple MCP Service Modes: By configuring the mode parameter, you can enable different running modes, including stdio, sse, and streamableHTTP. These modes can be combined to support various MCP tool integrations and provide a unified MCP service endpoint, making it possible to integrate with tools like CherryStudio as an MCP provider.

Installation & Usage

Step 1: Configure your MCP tools

Clone repository to your computer.

git clone git@github.com:HorseSword/notellm_mcp_server.git

Install packages with uv:

uv sync

Copy mcp_config.example.json to mcp_config.json, and edit it as standard MCP configure json file, like:

{
    "mcpServers":{
        "stdio-server-npx":{
            "command": "npx",
            "args":["-y","mcp-name"]
        },
        "stdio-server-uvx":{
            "command":"uvx",
            "args":"mcp-name"
        },
        "stdio-server-python":{
            "command": "uv",
            "args": ["run","python_code.py"]
        },
        "sse-server-name":{
            "type": "sse",
            "url": "http://localhost:11111"
        },
        "streamable-http-name":{
            "type": "streamableHttp",
            "url": "http://localhost:22222",
            "headers": {
                "Content-Type": "application/json",
                "Authorization": "Bearer YOUR_TOKEN"
            }
        }
    }
}

Step 2: Run as RESTful API server, for Joplin-Plugin-NoteLLM

Start the server:

uv run mcp_server.py

It will run on http://127.0.0.1:7302 by default.

You can also add --host and --port to run as you want.

Step 3: Change settings of Joplin-Plugin-NoteLLM

Go to settings of NoteLLM >= v0.6.0,

(1) Find "Advanced settings", and fill "URL for MCP Server (Preview)" part.

(2) Change "MCP for LLM (preview)" from "OFF" to "MCP (tool call)" below LLM1 to LLM3. Reminder: Your model must support "tool call".

Congratulations! Your NoteLLM can use MCP tools now.

Optional Step: Run as normal MCP server

You can also use this server as a normal MCP provider, and all MCPs to it can be user together. Such as:

uv run mcp_server.py --mode stdio for STDIO MCP;

uv run mcp_server.py --mode sse for SSE MCP;

uv run mcp_server.py --mode http for StreamableHTTP MCP.

You can configure it as following:

{
    "mcpServers": {
        "ANYTHING_HERE": {
            "name": "NoteLLM_MCP_Server",
            "type": "sse",
            "description": "local mcp server",
            "isActive": true,
            "tags": [],
            "baseUrl": "http://127.0.0.1:7302/sse"
        }
    }
}

Tech Stack

NoteLLM_MCP_Server is primarily built with the following technologies:

FastMCP: Handles the core logic of the MCP protocol.
FastAPI: Builds a high-performance API server, offering RESTful APIs for MCP service invocation.

Use Cases

NoteLLM_MCP_Server can be used in various scenarios where MCP service integration and provision are required, such as:

Providing MCP functionality for the Joplin plugin NoteLLM.
Acting as an MCP provider for tools like CherryStudio.
Deploying locally or in the cloud to offer a unified MCP service interface.
Remotely invoking and managing MCP services via API endpoints.
