Mcp Thinkgate

Routes Claude prompts through automatic complexity classification before they hit the model. Uses a fast Haiku call to bin incoming messages into fast, think, or ultrathink tiers, then returns the appropriate effort level and model recommendation. Exposes a classify_prompt tool when running as an MCP server in Claude Desktop, or works as a library import in agent frameworks. The actual value is in the classifier prompt itself, which decides the boundary between what needs extended thinking and what doesn't. Ships with a rule-based fallback if you skip the API key. Built for agent developers running mixed workloads where you're wasting tokens on trivial requests or under-allocating on complex ones.
