## Current MCP transport

Validator Master currently provides an MCP server over stdio transport for installed or local clients. There is no public hosted /mcp endpoint in Agent Readiness v0.1.
## Current MCP tools


- heartcode_evaluate_response — evaluate one AI-generated response using the deterministic Heartcode evaluator
- heartcode_evaluate_conversation — evaluate an ordered conversation for Heartcode trajectory and contextual findings
## Future hosted MCP boundary

A future hosted Streamable HTTP MCP surface should be added only for a concrete integration need and must retain the same quotas, global spend protection, kill switch, evidence boundaries, privacy limits, and no-secret guarantees as the public HTTP surface.
