Question 1

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

Accepted Answer

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.

Question 2

How do I use custom system prompts?

Accepted Answer

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.

Question 3

How do I manage conversations?

Accepted Answer

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

Question 4

What credentials does it need?

Accepted Answer

It reads `ANTHROPIC_API_KEY` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.
