Outline Server

Overview

This is a Model Context Protocol (MCP) server implementation that integrates with Outline. The server provides tools for AI agents (mostly Cursor) to interact with Outline's API, enabling document and collection management operations.

Features

• Search documents by query terms
• Create, retrieve, update, and delete documents
• List documents within collections
• Move documents between collections
• Manage collections (create, update, delete, list)

Installation

Prerequisites

• Node.js (v16 or later)
• npm or yarn
• Outline API key

Setup

1. Clone the repository:

git clone https://github.com/fellowapp/mcp-outline.git
cd mcp-outline

2. Install dependencies:

npm install

3. Create a .env file based on the .env.template file

4. Get you Outline API token from your personal settings.

5. Connect to your MCP client (like Cursor) NOTE: if you are connecting to Cursor, you technically don't need to do the whole .env file setup, but it can be usefull for local testing.

6. For connecting to Cursor, add this server to either your global or local project MCP settings with this:

"mcp-outline": {
     "command": "node",
     "args": [
       "<FULL_PATH_OF_CLONED_OUTLINE_MCP_REPO>/src/index.js"
     ],
     "env": {
       "API_URL": "https://dev.fellow.wiki/api",
       "API_KEY": "<OUTLINE_API_KEY>"
     }
   }

Architecture

This project implements the Model Context Protocol (MCP) standard for tool-based interactions. The architecture consists of:

src/
├── index.js                 # Main server entry point
├── outline.js               # Outline API client configuration
├── tools/
│   ├── handlers.js          # Centralized tool handlers mapping
│   ├── toolSchemas.js       # Centralized tool schemas
│   ├── document/            # Document-related tools
│   │   ├── index.js         # Export all document tools
│   │   ├── create.js        # Create document tool
│   │   ├── delete.js        # Delete document tool
│   │   ├── get.js           # Get document tool
│   │   ├── list.js          # List documents tool
│   │   ├── move.js          # Move document tool
│   │   ├── search.js        # Search documents tool
│   │   └── update.js        # Update document tool

The server handles incoming requests through a stdio transport layer and routes them to the appropriate tool handler based on the requested tool name.

Development

Adding New Tools

To add a new tool:

1. Create a new file in the appropriate directory (e.g., src/tools/document/my-tool.js)
2. Follow this template:

import { ErrorCode, McpError } from "@modelcontextprotocol/sdk/types.js";
import { outlineClient } from "../../outline.js";

const toolSchema = {
  name: "my_tool_name",
  description: "Description of what this tool does",
  inputSchema: {
    type: "object",
    properties: {
      // Define your parameters here
      param1: {
        type: "string",
        description: "Description of param1",
      },
    },
    required: ["param1"],
  },
};

async function myToolHandler({ param1 }) {
  try {
    // Implement your tool logic here
    const response = await outlineClient.post("/endpoint.name", {
      params: {
        param1,
      },
    });
    return response.data.data;
  } catch (error) {
    console.error(error);
    throw new McpError(ErrorCode.InvalidRequest, error.message);
  }
}

export { toolSchema, myToolHandler as handler };

3. Add your tool to the appropriate index.js file
