What is the A2a MCP Server?

A2A TrustGate: 4-gate firewall that screens every AI-agent action before it runs. 49 tools.

The short version

A2A TrustGate screens every action an agent takes before it runs, and writes the decision to an immutable, SIEM-ready audit trail. Not a policy document that says agents should behave — a control that stops the ones that don't, and the evidence to prove it.

  • Evaluate — — screen any command through the 4-gate firewall, allow / block / needs-review, in milliseconds
  • Pipelines — — named screening routes with their own policy and task history
  • Workspaces — — scoped multi-agent enforcement, one agent's action screened against the tenant policy
  • Channels — — HMAC-signed agent-to-agent messaging, contract-scoped
  • Devices & sites — — per-device policy, lock, bulk CSV import, and a global killswitch (network-ops)
  • Catalogues & licences — — register IP, mint scoped licences, access-log every reach (creative / IP owners)
