Agent identity & authorization
Every agent, verified at every action.
Drop-in software that gives each AI agent a scoped, expiring, revocable permission — and blocks anything that doesn’t match, with an audit trail you can prove.
Boring, deployable trust plumbing for AI agents. Not a blockchain.
The problem
A shared API key is not an identity.
Businesses are handing AI agents access to real systems faster than they can answer four basic questions. Today the answer is a key in a config file — and hope.
Who is this agent?
API keys identify a deployment, not the agent acting — and say nothing a third party can verify.
What may it do?
Agents borrow a human’s session or a service account’s standing privilege. Scope is all-or-nothing.
Who authorized that?
There’s no standard way to say who granted this agent this power — or to attenuate it per hop.
What did it do?
When something goes wrong, the logs show a service account. Actor, authority, and evidence aren’t connected.
When a leaked key is the only credential, the only kill switch is to rotate it — which breaks everything else using it. One compromised agent shouldn’t mean an outage.
How it works
One pipeline, checked on every call.
Put RogueZero in front of any tool — an MCP server or an HTTP API. Every request runs the same fail-closed sequence before your tool ever executes.
Identity
Every agent and operator gets a verifiable, portable identity — no blockchain, no accounts.
Capability
A signed permission: these tools, these scopes, until this expiry, granted by this operator.
Verify
Signature, issuer trust, expiry, audience, replay, revocation — checked at request time, every time.
Policy
A default-deny decision on the exact agent, tool, and scope. Anything unmatched is denied.
Audit
Every decision — allowed or denied — is written append-only, with evidence, never the secret.
The moment that lands
Revoke one agent. Instantly.
An agent gets compromised. One command revokes its permission — and the very next action it attempts is blocked, with the reason in the log.
No key rotation. No collateral damage. The difference between “we think it’s fine” and “we can prove it, and shut it down in one move.”
Why now
The layer everyone skipped.
Agents are being wired to tools at standard-protocol speed — and the identity underneath is missing.
Published MCP servers — the emerging standard for connecting agents to tools. Scans suggest most have no authentication at all.
Raised by adjacent companies building agent governance. The budget is real — and it’s all pointed at the decision layer, not the identity beneath it.
Major standards bodies (OpenID, CoSAI, W3C, the LF agentic-AI groups) independently name agent identity and delegation as the open gap.
Market context, not our traction — sources on request.
Built to adopt, not to study
The easiest agent security to run — whoever you are.
No PhD in identity required. The cryptography is real but invisible, like the certificates behind HTTPS. Everyone in the room gets it.
Drop-in, not a redesign
Middleware in front of your MCP or HTTP tools, and five plain verbs — create, issue, verify, revoke, inspect. No new protocol to learn.
One file to protect a tool
Wrap a real tool by editing one file. Secure by default — short-lived permissions, default-deny, fail-closed — so the easy path is the safe path.
One sentence, five minutes
Every action is checked, denied if it shouldn’t happen, and provable. See the whole thing run on a laptop in five minutes.

See it for yourself
The whole story, on a laptop.
Two commands run a complete, self-contained demo: create an agent, allow a call, deny one, revoke, and watch the same call get blocked — printing the full audit trail.
Private beta. Design partners get repo access and run it in minutes; a public npm install follows the security review.
