Ory vs Buildkite

Four of the last six shipping items are MCP Server work, and they follow a clear line: give an agent one bounded call instead of a scavenger hunt. get_build_failure_summary collapses build state, failed jobs, log tails, annotations, and Test Engine results into a single purpose-built tool; list_jobs now returns compact summaries by default with detail_level as an opt-in; log search dropped roughly 40% of its response size. Separately, the agent binary itself is moving on — v4 becomes the stable channel on 1 September 2026, retiring years-old deprecated behavior.

Token economy is the design constraint now. Nearly every MCP change is about returning less while staying useful — trimmed payloads, bounded summaries, annotation digests that avoid a second round trip — which is what CI data has to become before an agent can reason over it. On top of that Buildkite is adding agent-discoverable skill guides, so guidance is loaded on demand rather than crammed into tool descriptions. The platform work underneath is authorization and auditability: rolling OAuth refresh so an active agent session no longer breaks weekly, plus OAUTH_APPLICATION_AUTHORIZED events in the audit log.

Expect more single-call, purpose-built MCP tools along the failure-triage pattern and more discoverable guides beyond the first debugging one, with the September v4 cutover setting up agent capabilities that v3 compatibility was holding back.
