Hermes · Webhooks

If a tool can POST to a URL, it can trigger Hermes.

The webhook adapter runs an HTTP server on port 8644. Anything POSTs JSON to /webhooks/<route>, Hermes validates the HMAC signature, turns the payload into a prompt, runs the agent, and delivers the answer. Enable it, then define routes in config.yaml with a prompt template using {dot.notation} (e.g. {pull_request.title}). Deliver back as a github_comment or to any connected platform. The money saver: deliver_only: true skips the agent entirely (zero tokens, sub-second) for plain alerts. Create routes on the fly with hermes webhook subscribe. Every route needs an HMAC secret; sandbox the gateway since payloads are attacker-controlled.
