A Model Context Protocol (MCP) server for interacting with the DeepWriter API. This server provides tools for creating, managing, and generating content for DeepWriter projects through the standardized MCP interface.

Features

• Project Management: Create, list, update, and delete projects
• Content Generation: Generate content for projects using DeepWriter's AI
• Project Details: Retrieve detailed information about projects
• MCP Integration: Seamlessly integrate with Claude and other MCP-compatible AI assistants
• Standard MCP Features: Implements MCP protocol version 2025-03-26
• Transport Support: Stdio transport for local process communication

Building

npm run build

This will compile the TypeScript code into JavaScript in the build directory.

Testing

You can test the MCP server locally using the provided test scripts:

node test-mcp-client.js

or

node test-deepwriter-tools.js

TypeScript Configuration

The project uses TypeScript with ES modules and Node16 module resolution. Key TypeScript settings:

{
  "compilerOptions": {
    "target": "ES2022",
    "module": "Node16",
    "moduleResolution": "Node16",
    "outDir": "./build",
    "strict": true
  }
}

Security

• The server validates all inputs before processing
• API keys are never logged or exposed in error messages
• The stdio transport provides process isolation
• All external API calls use HTTPS
• Input validation prevents injection attacks

Prerequisites

• Node.js (v17 or higher)
• npm (v6 or higher)
• DeepWriter API key
• An MCP-compatible client (e.g., Claude for Desktop)

Installation

Installing via Smithery

To install deepwriter-mcp for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @deepwriter-ai/deepwriter-mcp --client claude

Manual Installation

1. Clone the repository:

   Copy

   git clone https://github.com/yourusername/deepwriter-mcp.git
   cd deepwriter-mcp

2. Install dependencies:

   Copy

   npm install

3. Create a .env file in the root directory with your DeepWriter API key:

   Copy

   DEEPWRITER_API_KEY=your_api_key_here

4. Build the project:

   Copy

   npm run build

Usage

Starting the Server

Start the MCP server:

node build/index.js

The server will listen on stdin for MCP requests and respond on stdout, following the MCP stdio transport specification.

Connecting to Claude for Desktop

To use the DeepWriter MCP server with Claude for Desktop:

1. Open your Claude for Desktop configuration file:

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

2. Add the server configuration:

   Copy

   {
     "mcpServers": {
       "deepwriter": {
         "command": "node",
         "args": ["/ABSOLUTE/PATH/TO/deepwriter-mcp/build/index.js"],
         "env": {
           "DEEPWRITER_API_KEY": "your_api_key_here"
         }
       }
     }
   }

3. Restart Claude for Desktop to load the new configuration.

MCP Protocol Support

Troubleshooting

Common Issues

1. API Key Issues:

   • Ensure your DeepWriter API key is correctly set in the .env file
   • Check that the API key is being passed correctly in tool arguments
   • Verify the API key has the necessary permissions

2. Connection Problems:

   • Make sure the DeepWriter API is accessible from your network
   • Check for any firewall or proxy settings that might block connections
   • Verify your network connection is stable

3. MCP Protocol Issues:

   • Ensure you're using a compatible MCP client
   • Check that the stdio transport is properly configured
   • Verify the client supports protocol version 2025-03-26

4. Parameter Naming:

   • The server supports both snake_case (project_id) and camelCase (projectId) parameter names
   • All parameters are case-sensitive
   • Required parameters must not be null or undefined

Debugging

For detailed logs, run the server with the DEBUG environment variable:

DEBUG=deepwriter-mcp:* node build/index.js

You can also check Claude for Desktop logs at:

• macOS: ~/Library/Logs/Claude/mcp*.log
• Windows: %APPDATA%\Claude\logs\mcp*.log
