   @claude-api Please answer using the API: What is the capital of France?

Advanced Features

1. Using System Prompts

   @claude-api {"system_prompt": "You are an expert fitness coach"} Create a workout plan

2. Managing Conversations

   Start a new conversation

@claude-api {"conversation_id": "project1"} Let's discuss Python

# Continue same conversation
@claude-api {"conversation_id": "project1"} Tell me more

# View conversation history
@claude-api get_conversation_history project1

# Clear conversation
@claude-api clear_conversation project1

Cost Management

• API calls use your Anthropic API credits and may incur charges
• Use the Professional Plan for regular queries
• Only use @claude-api when you specifically need:
  • Longer context windows
  • Custom system prompts
  • To bypass rate limits

MCP Tools Available

1. query_claude

* Make direct API calls to Claude
* Support for system prompts
* Conversation tracking

2. clear_conversation

* Reset conversation history
* Manage multiple conversation threads

3. get_conversation_history

* Retrieve conversation records
* Debug conversation flow

Development

The main server implementation is in src/claude_api_server.py. To extend functionality, you can add new tools using the @mcp.tool() decorator.

Example of adding a new tool:

@mcp.tool()
async def custom_tool(param: str) -> str:
    """
    Custom tool description
    
    Args:
        param: Parameter description
    """
    try:
        # Tool implementation
        return result
    except Exception as e:
        return f"Error: {str(e)}"

Troubleshooting

1. API Key Issues

* Verify your API key in .env
* Check Claude Desktop config paths
* Ensure API key has correct permissions

2. Connection Issues

* Check if MCP server is running
* Verify Python environment
* Check Claude Desktop logs

3. Usage Issues

* Ensure correct @claude-api syntax
* Check conversation IDs
* Verify system prompt format
