TL;DR: Private MCP servers are difficult to govern because cloud proxies cannot reach systems that stay behind the firewall, and ConductorOne argues that outbound-only bridging preserves containment while adding identity-aware policy, logging, and approvals for AI tool access. The practical shift is that reach and governance no longer need to be traded off for internal MCP deployments.
NHIMG editorial — what this means for AI and NHI governance
By the numbers:
- Only 18% of MCP server deployments implement any form of access scoping for tool permissions.
- 96% of organisations store secrets outside of secrets managers in vulnerable locations including code, config files, and CI/CD tools.
- 92% of organisations expose NHIs to third parties, raising concerns about supply chain security.
Questions worth separating out
Q: How should teams govern private MCP servers without exposing them to the internet?
A: Use an outbound-only control path that lets the governance layer reach the server without opening inbound access.
Q: Why do MCP tools create a governance problem for IAM teams?
A: MCP turns each tool into a potential permission boundary, which means IAM teams must govern many small access decisions instead of one broad application login.
Q: What do security teams get wrong about tunnels for internal AI access?
A: They often treat a tunnel as if it were an access control.
Practitioner guidance
- Map every internal MCP server to an identity owner Inventory which team owns each private MCP endpoint, which identities can reach it, and which approvals govern its use.
- Require request-level identity attribution Ensure every tool call is logged against the person or workload behind the request, not only against the connector process.
- Keep transport and authorisation separate Use the bridge only for reachability and keep policy evaluation, approvals, and audit in a dedicated governance plane.
What's in the full announcement
ConductorOne's full blog post covers the operational detail this post intentionally leaves for the source:
- How C1 Bridge is deployed as a container or binary inside private networks without inbound firewall changes.
- How the governance plane classifies tools and attaches identity context to AI client requests.
- How the same control plane can extend across hosted MCP servers and internal systems.
- How the outbound-only design fits regulated environments that cannot accept inbound exposure.

Private MCP governance fails when teams assume containment and control are mutually exclusive. The article addresses a real architectural tension: internal servers stay off the internet precisely because they are sensitive, yet governance often reaches only what is already exposed. That assumption breaks once the governance layer cannot see the server at all. The implication is that private deployment is not itself a control, and reachability has to be designed into identity governance from the start.
A few things that frame the scale:
- 92% of organisations expose NHIs to third parties, raising concerns about supply chain security, according to Ultimate Guide to NHIs.
- 96% of organisations store secrets outside of secrets managers in vulnerable locations including code, config files, and CI/CD tools.
A question worth separating out:
Q: Who should own MCP gateway governance in an enterprise AI programme?
A: Ownership should sit with the teams responsible for identity, security architecture, and platform governance together, because MCP gateways span access control, routing, and observability. Treating the gateway as only a network component leaves policy gaps. Treating it as only an AI platform feature leaves accountability unclear.
