An hourly budget for MCP calls without a key

MCP tool calls without a key share an hourly budget per address. Failed calls use it up six times faster than ones that work, and calls with a key are never counted.

The hosted MCP server answers agents without a key, so one noisy caller could slow it for everyone. Calls without a key now share an hourly budget per address.

  • Each tool call uses one unit and a failed one uses six, so an agent stuck retrying a bad call runs out first.
  • Past the budget the call answers 429 with when to try again and how to get a key.
  • Calls with an API key are never counted.
