HTTP API
Agent API
Use the integration API to create approvals, poll for status, and wire callbacks into your orchestration layer. Designed for idempotent retries and explicit error surfaces.

Whether you ship long-running workers or chatty copilots, the contract is the same: create an approval, wait for resolution, receive the outcome.
MCP
Adapter & tooling
Expose HITL tools to external agent runtimes through an MCP-style adapter in this monorepo— ideal when your agents already speak MCP and you want approvals without bespoke glue code.
Implementation details live alongside the API service in the repository; ask your team for the internal runbook if you self-host.
