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

Clone the repository (if applicable)
Navigate to the project directory:
```
cd mcp-anthropic
```
Install dependencies:
```
npm install
```
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

Build the TypeScript code:
```
npm run build
```
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.
