FAQ from Claude Desktop API Integration via MCP

What is the difference between the Professional Plan and API usage?

The Professional Plan is the default for regular conversations within plan limits. API usage via this MCP server provides longer context windows, custom system prompts, and bypasses rate limits.

How do I use custom system prompts?

Prefix your message with @claude-api {"system_prompt": "You are an expert fitness coach"} followed by your request. The system prompt will be applied to that API call.

How do I manage conversations?

Use @claude-api {"conversation_id": "your_id"} to start or continue a conversation. Use @claude-api get_conversation_history <id> to view history or @claude-api clear_conversation <id> to reset it.

Are there costs for API calls?

Yes, API calls use your Anthropic API credits and may incur charges. Use the Professional Plan for regular queries and only use @claude-api when you specifically need longer contexts, system prompts, or to bypass rate limits.

How do I troubleshoot API key issues?

Verify your API key in the .env file, check that the Claude Desktop configuration file paths are correct, and ensure the API key has the correct permissions.
