Port AI graduated from answering questions about the catalog to changing it, with approval.
Port is an internal developer portal whose center of gravity has moved to Port AI. Over ten months it went from an open-beta chat assistant to an agent that plans and executes real platform changes — creating blueprints, upserting entities, triggering workflows — behind a plan the user approves first. The surrounding platform work is almost entirely extensibility: a public plugins repo, Custom Widgets, Workflows in open beta, and MCP connectors that pull external tools into the same chat.
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.

The arc is assistant to gateway to executor. March made Port AI a front end for other vendors' tools via external MCP servers; June put a visual automation builder underneath it; July let the AI drive both, with Plan and Build modes and per-step traces. Each release widens what the agent may touch while keeping a human approval gate in front of it, and the extensibility work — plugins, widgets, bring-your-own LLM endpoint — exists so customers can extend the surface the agent operates on.
Expect the approval gate itself to become the product surface: policy governing which plans may execute unattended, tied to the Dynamic RBAC and permissions simulator already shipped. The step-by-step plans and per-step traces in the July release are the groundwork for granting scoped autonomy.

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.
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.
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.
