🤖Agentic Gateway

Configure the P0 AI Gateway and the upstream MCP servers it fronts, so P0-managed AI agents can access them under runtime authorization policy.

The Agentic Gateway integration puts runtime authorization in front of the MCP servers in your environment, so agents don't operate on loose delegation or standing privilege and every action stays attributable. The P0 AI Gateway sits in the data path between your agents and your MCP servers, verifies the identity of the originator and the agent on every tool call, and evaluates each action against the authorization policy defined in the P0 AuthZ Control Plane™ for Agents before it reaches its target.

The Agentic Gateway integration is a preview feature.

This integration has three components:

Component	Use
Gateway	Registers your self-hosted P0 AI Gateway deployment with P0 so it can enforce policy and report activity.
Identity provider	Enrolls an external identity provider so its JWT-authenticated agents are trusted at the gateway.
MCP server	Configures an upstream MCP server behind the gateway. Once configured, it becomes available to P0-managed agents across your organization.

Prerequisites

• An existing P0 account at p0.app.

• A deployed P0 AI Gateway. See Deploying the P0 AI Gateway. This is a prerequisite for the Gateway component.

How it works

1. Register the gateway. After deploying the gateway into your environment, register it with P0 so the AuthZ Control Plane can supply policy and collect audit activity.

2. Enroll an identity provider. Tell the gateway which token issuer to trust so its JWT-authenticated agents are accepted.

3. Configure upstream MCP servers. Declare each MCP server you want to expose behind the gateway. P0 supports two kinds:

   • Predefined: P0-authored server definitions

   • Custom: servers you define yourself

Next steps

• Connect your agents. Each developer points their own agent at the configured server through the gateway. For Claude Code, see Use MCP servers with Claude Code.

Once an agent connects, the gateway authenticates every tool call, authorizes it against policy, and logs it. See Requesting access for how agents request and use just-in-time access, and Agentic Access Policies for governing those requests.
