Outline MCP Server

A Model Context Protocol (MCP) server for Outline that enables reading and writing documents through the Outline API.

Features

• Read Documents: Get individual documents, search, and list documents
• Write Documents: Create, update, and delete documents
• Collection Management: List and retrieve collection information
• Full Text Search: Search across all documents in your Outline instance
• Markdown Support: Create and edit documents with full Markdown formatting

Quick Start (npx)

The easiest way to use this server is via npx — no cloning or building required. Point your MCP client at it directly:

{
  "mcpServers": {
    "outline": {
      "command": "npx",
      "args": ["-y", "getoutline-mcp-server"],
      "env": {
        "OUTLINE_API_KEY": "your-secret-api-token",
        "OUTLINE_BASE_URL": "https://your-outline-instance.com"
      }
    }
  }
}

See Configuration for how to obtain the API token.

Installation (from source)

For local development, or to run from source instead of npm:

1. Clone or download this repository
2. Install dependencies:

   npm install

3. Build the project:

   npm run build

Configuration

Before using the server, you need to set up your Outline API credentials:

1. Get your Outline API token:

   • Log into your Outline instance (e.g., https://app.getoutline.com)
   • Go to Settings → API Tokens
   • Create a new token

2. Set environment variables:

   export OUTLINE_BASE_URL="https://your-outline-instance.com"
   export OUTLINE_API_KEY="your-api-token-here"

Usage

Running the Server

Start the MCP server:

npm start

The server communicates via stdio and is compatible with any MCP client.

Development

Project Structure

src/
├── index.ts           # Main MCP server implementation
├── outline-client.ts  # Outline API client

Scripts

• npm run build - Compile TypeScript to JavaScript
• npm run dev - Build and run the server
• npm run watch - Watch for changes and rebuild
• npm start - Run the compiled server

Building

npm run build

The compiled JavaScript will be output to the dist/ directory.

Configuration with MCP Clients

To use this server with an MCP client, you'll need to configure it to run this server. The exact configuration depends on your client, but generally you'll need to:

1. Specify the command to run: node /path/to/outline-mcp-server/dist/index.js
2. Set the environment variables for your Outline instance
3. Configure the client to use stdio transport

Client Configuration Examples

Claude

For clients like Claude that use a JSON configuration file, add the following to your mcp-servers.json. The recommended approach uses npx, so there is nothing to clone or build:

{
  "mcpServers": {
    "outline": {
      "command": "npx",
      "args": ["-y", "getoutline-mcp-server"],
      "env": {
        "OUTLINE_API_KEY": "your-secret-api-token",
        "OUTLINE_BASE_URL": "https://your-outline-instance.com"
      }
    }
  }
}

Alternative: run from source

If you have cloned and built the project locally, point the client at the compiled dist/index.js instead:

{
  "mcpServers": {
    "outline": {
      "command": "node",
      "args": ["/path/to/your/projects/outline-mcp-server/dist/index.js"],
      "env": {
        "OUTLINE_API_KEY": "your-secret-api-token",
        "OUTLINE_BASE_URL": "https://your-outline-instance.com"
      }
    }
  }
}

Make sure to replace the args path with the absolute path to the index.js file in your project, and fill in your actual credentials in the env block.

Cursor

For clients like Cursor, you can typically set environment variables directly within the client's settings or by launching the client from a terminal where you have already exported the variables.

export OUTLINE_BASE_URL="https://your-outline-instance.com"
export OUTLINE_API_KEY="your-secret-api-token"

# Then launch Cursor from this terminal
/path/to/Cursor.app/Contents/MacOS/Cursor

API Rate Limits

Be aware that Outline may have API rate limits. The server doesn't implement rate limiting internally, so you may need to handle this at the client level if you're making many requests.

Error Handling

The server includes comprehensive error handling and will return descriptive error messages for common issues like:

• Missing or invalid API credentials
• Network connectivity problems
• Invalid document IDs
• API rate limit errors

Security Notes

• Store your API token securely using environment variables
• Never commit your API token to version control
• Consider using restricted API tokens with minimal required permissions
• Be cautious when allowing others to use your MCP server as it has full access to your Outline instance
