What is Buildkite?

Buildkite is rebuilding CI as something agents drive, not just humans.

Buildkite's recent releases split in two: MCP tooling for agents - list_tests, wait_for_build, compliance with the stateless MCP spec - and broader REST/GraphQL coverage so setup, governance, and troubleshooting can run headless. Conventional CI work continues underneath, with checkout configuration in pipeline YAML and OpenTelemetry job log export. The framing on nearly every note is what an agent can now do without a human in the loop.

What is WorkOS?

WorkOS is building identity for agents while quietly fixing the sign-up funnel.

WorkOS ships several small entries a week, and August splits cleanly in two. One half is authentication housekeeping for human users: an Android SDK, deliverability checks that reject undeliverable addresses at sign-up, invitation acceptance counting as email verification, and a reversible SCIM proxy for migrating directory connections without downtime. The other half is agent infrastructure — Agent Registration via the auth.md protocol, and the Pipes Token Proxy that calls third-party APIs on a user's behalf without the application ever touching their token.

Buildkite is rebuilding CI as something agents drive, not just humans.

◆ Current state

Buildkite's recent releases split in two: MCP tooling for agents - list_tests, wait_for_build, compliance with the stateless MCP spec - and broader REST/GraphQL coverage so setup, governance, and troubleshooting can run headless. Conventional CI work continues underneath, with checkout configuration in pipeline YAML and OpenTelemetry job log export. The framing on nearly every note is what an agent can now do without a human in the loop.

◆ Where it's heading

Buildkite is arguing that CI should be forge-independent, and it is now backing that with coverage: GitHub, GitLab, Bitbucket, and as of this week Cursor's Origin, where it shipped as a launch partner on day one. On the agent side the pattern is removing the workarounds automation used to need - a wait tool instead of a polling loop, aggregated test metrics instead of assembling individual runs, an early failure signal instead of waiting for a job to exit. Each release converts a hand-rolled agent behavior into a first-class primitive.

◆ Prediction

The read side of the MCP server is now largely covered, so expect write-side tools next - retrying jobs, unblocking builds, creating or editing pipelines from an agent - following the same pattern the REST expansion just established.

WorkOS is building identity for agents while quietly fixing the sign-up funnel.

◆ Current state

WorkOS ships several small entries a week, and August splits cleanly in two. One half is authentication housekeeping for human users: an Android SDK, deliverability checks that reject undeliverable addresses at sign-up, invitation acceptance counting as email verification, and a reversible SCIM proxy for migrating directory connections without downtime. The other half is agent infrastructure — Agent Registration via the auth.md protocol, and the Pipes Token Proxy that calls third-party APIs on a user's behalf without the application ever touching their token.

◆ Where it's heading

The agent work is the strategic line. Registration gives an agent an identity of its own instead of a borrowed human session; the token proxy means an application acting for a user never holds the credential. Together they describe a stack where an agent can be authorized, audited and revoked as a first-class principal. The human-auth releases are conversion and migration work — the deliverability check and SCIM Bridge both remove reasons a customer stalls — which is what a developer-infrastructure company does while its next category is still forming.

◆ Prediction

Registration and the token proxy leave scoping and revocation as the visible gaps, so expect per-agent permissions or consent surfaces next. Whether auth.md gains adoption beyond WorkOS is not something these entries can answer.
