/ Enterprise MCP Gateway

The MCP Gateway, Illustrated

Enterprises are connecting AI agents to internal tools through MCP — and that creates a new trust boundary: which agents can reach which tools, which credentials they use, where traffic routes, and how every call is audited.

This guide maps the whole governed path in twelve pictures, so you can see how one policy gate replaces a tangle of one-off integrations.

01

MCP Sprawl

Without a governed path, agents, tools, and private APIs become a tangle of one-off connections.

MCP sprawl

Why it mattersSecurity and platform teams need ownership, routing, policy, and audit before MCP adoption spreads across teams.

02

One Governed Path

Approved MCP traffic moves through one policy gate instead of many bespoke integrations.

One governed path

Why it mattersThe gateway becomes the shared enforcement point for identity, policy, credentials, routing, sessions, and audit.

03

Deploy Where Trust Requires

The runtime can be deployed in hybrid mode or fully self-hosted mode, depending on the customer's trust boundary.

Deploy where trust requires

Why it mattersPrivate runtime traffic and customer-controlled infrastructure can stay inside the environment the customer requires.

04

Register A Capability

Server and API owners register capabilities with owner, risk, endpoint, and environment metadata.

Register a capability

Why it mattersA tool cannot be governed until the gateway knows what it is, who owns it, where it runs, and how risky it is.

05

Convert APIs Safely

Selected REST/OpenAPI operations can be approved and exposed as governed MCP tools.

Convert APIs safely

Why it mattersEnterprises can reuse existing internal APIs without blindly publishing every operation or bypassing policy.

06

Approve A Snapshot

Approved capabilities are tied to versioned metadata, policy references, and a recorded snapshot.

Approve a snapshot

Why it mattersRuntime decisions can point back to what was approved, which policy was in force, and which version was used.

07

Make Agents Accountable

Agents are registered with owner, client surface, environment, and credential mode.

Make agents accountable

Why it mattersNon-human agents should not be treated as loose API keys; every call needs attributable actor context.

08

Filter Discovery

Agents only discover tools that policy allows them to see.

Filter discovery

Why it mattersUnauthorized tools are hidden before use, not merely denied after the agent has already seen them.

09

Govern Each Call

Each tool-call request is checked for authentication, policy, schema, and registered routing.

Govern each call

Why it mattersEvery allowed call has a clear reason to proceed, and every denied call has a machine-readable reason to stop.

10

Broker Credentials

Credentials are resolved through the gateway and customer secret stores, not handed raw to agents.

Broker credentials

Why it mattersService, delegated, and agent-scoped credentials can be governed centrally while private routes stay private.

11

Control Sessions

Stateful sessions have IDs, duration limits, reconnect behavior where supported, and revocation controls.

Control sessions

Why it mattersLong-running sessions need lifecycle control, not just one-time request checks.

12

Leave An Audit Trail

Every call should leave a record of who acted, which policy decided, which credential mode was used, and what happened.

Leave an audit trail

Why it mattersSecurity teams can investigate, export, and respond without reconstructing events from scattered server logs.

We are looking for teams who want to work closely with us on governed MCP adoption.

The best first pilot is narrow: register one private MCP server, convert one selected REST/OpenAPI operation, attach policy and credentials, then run real agent calls through the gateway with audit enabled.

If your security, platform, or AI infrastructure teams are already experimenting with MCP, we would like to partner with you directly: map your first use case, deploy inside your trust boundary, and build the governance path your teams can actually use in production.
