MCP governance: what regulated enterprises are missing

TL;DR: Regulated enterprises adopting MCP are running into five predictable failures: no registry, all-or-nothing tool access, broken auth, tool poisoning, and fragmented audit trails, according to Tetrate. The governance problem is architectural, not procedural, because enterprises need a single governed boundary for inventory, authorization, and traceability.

Key questions

Q: What breaks when MCP servers are not registered centrally?

A: Unregistered servers create shadow deployment.

Q: Why do MCP deployments increase identity and access risk?

A: MCP increases risk because it connects untrusted model output to real systems that can act on it.

Q: How should security teams restrict MCP tools for production agents?

A: Security teams should place a policy enforcement layer between the agent and the MCP server, then assign each agent persona a minimal allow list.

Practitioner guidance

• Establish a governed MCP registry Make the registry the only approved path to production servers, with versioning, ownership, and enforced request-path checks.
• Scope agents to specific tools Define MCP profiles that expose only the exact tools needed for each agent use case, not the full server surface.
• Terminate authentication at a proxy boundary Move downstream credential custody out of laptops and into a central boundary that normalises auth across servers.

Bottom line: MCP adoption becomes a governance problem when server sprawl, permissive tool exposure, and fragmented identity controls outpace the protocol’s technical usefulness.
