How are you authorizing AI agents that call MCP servers?

Keydris has launched a trust infrastructure for AI agents that call MCP servers, centered on a Gateway that issues scoped, signed KIT tokens verified by lightweight Kit Reader middleware before any tool call reaches the server. The system provides an append-only, hash-chained audit log and machine-speed revocation across boundaries, designed to meet the standards of CISOs, platform engineers, and compliance leads.

Trust Infrastructure for the autonomous economy - Trust Infrastructure for the autonomous economy - EVERY ACTION, CHECKED The Keydris Gateway sits at the heart of the flow: it issues each agent a kit, scoped by the policies you set in the Keydris app. Agents present that kit with every tool call, and the Kit Reader : lightweight middleware installed on top of your MCP server : checks it with the gateway and allows or denies the call before it ever reaches the server.

Revocation is part of verification itself — the next check fails, and the audit trail shows exactly when. 09:00:00Z · authority revoked 09:00:03Z · revocation feed synced 09:00:41Z · action attempted → refused · record signed “Show me the record you would hand an auditor.” Compliance lead A signed sequence of decisions, handed over as it stands: each record names the request, the policy in force, the checks, and the outcome. record kd evt 29fa… · signed THE KIT And the layer stays neutral. Keydris is independent of any model, vendor, platform, or rail. A requirement for infrastructure that sits between institutions rather than inside one of them. Signed KIT token • Scoped permissions • Minimum privilege Keydris issues the agent a signed token, the KIT. It states what the agent may do and for how long. Minimum privilege by default. Append-only log • Hash-chained • Immutable record The authorization is bound to an append-only, hash-chained log. An immutable record of what the agent was permitted to do. Enforced at the front door • Proof checked first • No proof, no connection Enforcement is at the counterparty's front door. The receiving system verifies the token before the agent can connect or act. Machine-speed revocation • Across every boundary • Fails verification instantly Authority is pulled at machine speed, across every boundary. A revoked token fails verification the instant permission should end.
