Engine endpoint

This tool delegates to the kp-engine endpoint:

POST /v1/kp/bhadhakasthana

The engine is a private internal service. All public access flows through the MCP server, which handles auth, rate limiting, and response compaction.

Birth data

This tool requires birth data. If you have already called set_birth_profile in the same conversation, the MCP server injects those fields automatically and you can omit them from the call.
