Start with the Bazel layer you need to investigate.

Bazel observability

Trace failures, tests, timing, and critical paths to the evidence behind them.

Remote cache misses

Compare action keys, inputs, platforms, and environments across builds.

Remote execution

Separate queueing, transfers, worker time, and execution bottlenecks.

Build Event Protocol

Turn Bazel BEP events into searchable build, target, and test history.

MCP for Bazel

Give coding agents structured build evidence instead of raw log fragments.

Find the failure. Explain the cache miss. Unblock RBE.

Investigate the build graph and execution infrastructure as one system.

01

Find the failing action

Trace a failed target or test to the recorded action and its execution evidence.

02

Explain the cache miss

Compare key-forming inputs and execution context instead of guessing from logs.

03

Unblock remote execution

Separate queueing, transfers, worker saturation, and execution time across your RBE fleet.

04

Give your AI agent context

Give MCP-compatible agents structured build history and failure evidence.

Connect the signals your build infrastructure can provide.

Keep Bazel and your execution backend. Configure Build Event Protocol ingestion first, then add supported cache, completed-action, metric, trace, or cost sources for the views you need.

  • Bazel Build Event Protocol (BEP)
  • Remote-cache events when connected
  • Buildbarn completed-action records
  • OpenTelemetry metrics, logs, and traces when connected

Let your coding agent investigate the build.

Hermetiq makes build history and failure evidence queryable through MCP, so an agent can inspect what ran, explain what changed, and recommend its next action.
