MCP Anthropic Server (mcp-anthropic)

An MCP (Model Context Protocol) server providing tools to interact with Anthropic's experimental prompt engineering APIs.

Features

Provides the following tools:

• generate_prompt: Generates a prompt based on a task description.
• improve_prompt: Improves an existing prompt based on feedback.
• templatize_prompt: Converts a concrete prompt example into a reusable template.

Setup

1. Clone the repository (if applicable)
2. Navigate to the project directory:

   cd mcp-anthropic
   

3. Install dependencies:

   npm install
   

4. Configure API Key:
   • Create a .env file in the project root (./mcp-anthropic/.env).
   • Add your Anthropic API key to the .env file:

     ANTHROPIC_KEY=your_anthropic_api_key_here
     

   • Ensure this file is not committed to version control (it should be covered by .gitignore).
   • Note for LibreChat Integration: For specific instructions on setting up and running this server as a child process within LibreChat (including API key handling), please refer to the documentation.md file.

Running the Server

1. Build the TypeScript code:

   npm run build
   

2. Start the server:

   npm start
   

   The server will start and listen for MCP connections. You should see output indicating the server has started and which tools are registered.
