Hydrant Authentication

Authentication

Hydrant agents authenticate using a custom OAuth2 flow called service_auth. The agent registers via POST https://hydrant.dev/api/agent-auth/identity, receives a claim_token, polls https://hydrant.dev/api/auth/oauth2/token with grant_type=urn:workos:agent-auth:grant-type:claim to obtain an access_token, then uses the token as a Bearer token in the Authorization header for calls to https://hydrant.dev/api/mcp.

Hydrant declares 1 security scheme(s) across its OpenAPI definitions.
