The pipeline is the core mechanism that gives you visibility into every MCP request and response. Each request flows through Ultra’s observability layers — capturing traces, structured logs, audit events, and metrics — before reaching the upstream server.

​
Request and Response Flow

Every request and response passes through the same set of observability layers, so nothing slips by unrecorded.

​
Audit Guarantees

The audit layer is designed to block a successful operation if it can’t be recorded. This is a deliberate security choice: every completed MCP call must have a corresponding audit record, so compliance teams can rely on completeness. The other layers absorb errors silently — observability should never break your workflow.
Auth and Policy enforcement are planned but not yet implemented. See Roadmap: Policy Engine.
