openpolicyagent.org
Open Policy Agent (OPA) is an open source policy engine for evaluating policy decisions against structured input and policy/data written in Rego. It is used to decouple policy enforcement from applications, services, and infrastructure tooling.
openpolicyagent.org documents a public self-hosted OPA REST API and the public `opa` CLI; no first-party GraphQL API or MCP connect endpoint on openpolicyagent.org was found.
