Do I need an API key to use mcp-thinkgate?

No, the server works without an API key using rule-based classification. However, setting ANTHROPIC_API_KEY enables AI-powered classification via Claude Haiku for more accurate routing decisions.

What's the difference between rule-based and AI-powered classification?

Rule-based classification uses heuristics to determine complexity, while AI-powered classification (with ANTHROPIC_API_KEY set) uses Claude Haiku for more nuanced and accurate complexity assessment.

How does mcp-thinkgate decide between extended thinking and standard mode?

The server analyzes prompt complexity and routes to extended thinking for tasks requiring deep reasoning, and standard mode for simpler queries. The classification method depends on whether you've configured an API key.

Can I use mcp-thinkgate without Anthropic's API?

Yes, the rule-based fallback works independently. The ANTHROPIC_API_KEY is optional and only enhances classification accuracy when provided.

What transport protocol does mcp-thinkgate use?

mcp-thinkgate uses stdio transport, making it lightweight and easy to integrate into local development environments without network overhead.
