MCP server for LogSeq

MCP server to interact with LogSeq via its API.

Components

Tools

The server implements multiple tools to interact with LogSeq:

list_graphs: Lists all available graphs
list_pages: Lists all pages in the current graph
get_page_content: Return the content of a single page
search: Search for content across all pages
create_page: Create a new page
update_page: Update content of an existing page
delete_page: Delete a page

Example prompts

It's good to first instruct Claude to use LogSeq. Then it will always call the tool.

Example prompts:

Get the contents of my latest meeting notes and summarize them
Search for all pages where Project X is mentioned and explain the context
Create a new page with today's meeting notes
Update the project status page with the latest updates

Configuration

LogSeq API Configuration

You can configure the environment with LogSeq API settings in two ways:

Add to server config (preferred)

{
  "mcp-logseq": {
    "command": "uvx",
    "args": [
      "mcp-logseq"
    ],
    "env": {
      "LOGSEQ_API_TOKEN": "<your_api_token_here>",
      "LOGSEQ_API_URL": "http://localhost:12315"
    }
  }
}

Create a .env file in the working directory with the required variables:

LOGSEQ_API_TOKEN=your_token_here
LOGSEQ_API_URL=http://localhost:12315

Development

Building

To prepare the package for distribution:

Sync dependencies and update lockfile:

uv sync

Debugging

Since MCP servers run over stdio, debugging can be challenging. For the best debugging experience, we recommend using the MCP Inspector.

You can launch the MCP Inspector via npm with:

npx @modelcontextprotocol/inspector uv --directory /path/to/mcp-logseq run mcp-logseq
