MCP authorization server
An MCP authorization server exposes authorization operations over Model Context Protocol so AI agents and IDEs query and operate the same policy control plane as humans.
Agents already call tools via MCP. Putting authorization on that path keeps decisions in policy-as-code instead of hard-coded prompts.

Pair Herald with Writ for governance and Verdict when human approval must gate high-impact agent actions.
