# Verified, Not Just Listed

###### JetStream Verified MCP Catalog™ is a curated set of MCP servers, each ingested, scanned, hardened, and cryptographically attested before it ships, so an agent only ever calls code that has been vetted before it runs.

Your agents are calling MCP servers no one has inspected. The market’s fix was a longer catalog, but a server selected from a catalog is not a control. Each server is code you did not write, wired into systems that matter.

JetStream hardens a verified set and governs every request through one hub, the same way it secures the rest of the AI estate. This white paper shows why that verified set is faster than a longer list, not slower.

###### There are three tensions a bigger catalog cannot resolve.

The white paper shows each tension and the control that resolves it, from a verified building block to a single hub that governs every request

- **Why a bigger catalog widens the attack surface it claims to manage**. Every unexamined server is new code running with real reach. The white paper lays out what “hardened” means in practice: a server selected, scanned, remediated, and attested before an agent is ever allowed to call it, through JetStream Verified MCP™.

- **Why an agent ends up holding a DELETE it never****needed**. Server-level access is all-or-nothing until someone makes it otherwise. The white paper shows tool-level filtering that lets a team allow a read tool and block a destructive one, instead of accepting the whole bundle.

- **Why the audit evidence does not exist until an examiner asks for****it**. Drift happens without a code deploy, so the record has to be rebuilt after the fact. The white paper illustrates how every agent maps to an approved Blueprint through JetStream AI Blueprints™, so a swapped model or an expanded permission leaves an artifact, not a gap.

###### Governance is not a brake on MCP adoption. It is what clears the path.
