The Private Connector

Your most useful tools often live on private systems.

This guide shows how governed calls reach internal MCP servers and APIs through approved connector paths โ€” with health, revocation, and path audit โ€” without exposing them publicly.

01

Private Systems Stay Inside

Private MCP servers and internal APIs stay inside the customer network.

Private Systems Stay Inside

Why it mattersMCP adoption should not require public doors to private systems.

02

Gateway Picks Private Route

Gateway policy selects the approved private route instead of a public road.

Gateway Picks Private Route

Why it mattersRouting is part of governance, not just connectivity.

03

Direct Private Endpoint

A sealed route connects direct and private endpoints without a public hop.

Direct Private Endpoint

Why it mattersThe path should match the customer's trust boundary.

04

Outbound-Only Connector

An outbound-only connector avoids inbound knocks while maintaining the approved path.

Outbound Only Connector

Why it mattersMany teams can accept outbound posture more readily than inbound exposure.

05

Connector Auth Seal

Connector authentication verifies trusted peers and rejects mismatches.

Connector Auth Seal

Why it mattersPrivate routing still needs strong connector identity.

06

Per-Backend Allowlists

Each backend can allow only approved sources.

Per Backend Allowlists

Why it mattersA connector path should not become blanket access to every backend.

07

Private MCP Tool Call

A tool request travels through the connector path and returns a private MCP result.

Private MCP Tool Call

Why it mattersThe route should be observable through real work, not only drawn as a network path.

08

Internal API Private Route

Selected internal API operations can stay private while becoming governed MCP tools.

Internal API Private Route

Why it mattersAPI-to-MCP should not require copying the API into a public surface.

09

Connector Health Report

Connector heartbeat, last-seen state, and status report show whether the path is ready.

Connector Health Report

Why it mattersOperators need path health before blaming policy or the backend.

10

Unhealthy Path Visible

When a route is unhealthy, requests wait and operators get a visible notice.

Unhealthy Path Visible

Why it mattersPrivate routing needs observable failure states, not silent confusion.

11

Connector Revocation

A connector can be revoked, cut from the path, and recorded with a reason.

Connector Revocation

Why it mattersEvery private route needs a clean stop control.

12

Connector Path Audit

Path metadata ties connector ID, backend ID, policy decision, and timestamp together.

Connector Path Audit

Why it mattersAudit should explain not only who called a tool, but how the private route was used.

Reach a private system without public exposure

We are looking for teams whose platform and network teams want governed MCP access to private systems.

Start with one private MCP server or one internal API operation. Define the connector path, authenticate it, allowlist the backend, run a tool call, observe health, test revocation, and review the path audit together.

The goal is to prove private access without public exposure.
