LogSeq MCP server

The Logseq MCP Server provides direct integration with Logseq's knowledge base, enabling large language models to interact with Logseq graphs, create pages, manage blocks, and organize information programmatically through the Model Context Protocol.

Installation

Using pip

Install the server using pip:

pip install mcp-server-logseq

From source

Clone and set up the repository:

git clone https://github.com/dailydaniel/logseq-mcp.git
cd logseq-mcp
cp .env.example .env
uv sync

Run the server:

python -m mcp_server_logseq

Configuration

API Key Setup

1. Generate an API token in Logseq by navigating to API → Authorization tokens
2. Set the environment variable:

export LOGSEQ_API_TOKEN=your_token_here

Alternatively, pass the token via command line:

python -m mcp_server_logseq --api-key=your_token_here

Graph Configuration

The default URL is http://localhost:12315. To customize:

python -m mcp_server_logseq --url=http://your-logseq-instance:port

Usage with Claude Desktop

Add the following configuration to your Claude Desktop setup:

If you encounter errors, try using version 0.0.1:

{
  "mcpServers": {
    "logseq": {
      "command": "uvx",
      "args": ["mcp-server-logseq==0.0.1"],

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "logseq" '{"command":"uvx","args":["mcp-server-logseq"],"env":{"LOGSEQ_API_TOKEN":"<YOUR_KEY>","LOGSEQ_API_URL":"http://127.0.0.1:12315"}}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "logseq": {
            "command": "uvx",
            "args": [
                "mcp-server-logseq"
            ],
            "env": {
                "LOGSEQ_API_TOKEN": "<YOUR_KEY>",
                "LOGSEQ_API_URL": "http://127.0.0.1:12315"
            }
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "logseq": {
            "command": "uvx",
            "args": [
                "mcp-server-logseq"
            ],
            "env": {
                "LOGSEQ_API_TOKEN": "<YOUR_KEY>",
                "LOGSEQ_API_URL": "http://127.0.0.1:12315"
            }
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
