# Using the P0 AI Gateway

See registered clients, configured MCP servers, and call activity in Agentic Access, and connect your own agents to a configured gateway.

The **Agentic Access** page is where you see what's connected to your gateway: registered clients, the MCP servers they can reach, and their MCP and A2A call activity. It appears once a gateway is registered, to Owners, Security Reviewers, Assessment Users, and Assessment Viewers. Configuring the gateway itself, and the MCP servers and A2A bridges behind it, is covered in [AI gateway](/agentic-access/agentic-gateway.md).

### Clients

Lists every MCP client and agent identity registered to connect through the gateway: its provider (a federated identity, or a client platform like Claude Code), its client ID, and who registered it and when. Select a row for more detail. Some roles can also register a client directly from this tab. See [Connect an MCP client](/agentic-access/using-the-gateway/connect-an-mcp-client.md).

### MCP servers

Lists the MCP servers this gateway exposes to registered clients, with each one's type and endpoint. This tab is read-only — configure what it shows on the [AI gateway](/agentic-access/agentic-gateway.md) component page.

### Event log

Lists the MCP tool calls and A2A agent calls this tenant's gateways observed. See [Event log](/agentic-access/using-the-gateway/event-log.md) for filtering, export, and the full API reference.

## Connect your own agents

* [Connect an MCP client](/agentic-access/using-the-gateway/connect-an-mcp-client.md): register an MCP client and connect it to a server behind the gateway, with a Python example. The [Agentic client registration API](/agentic-access/using-the-gateway/connect-an-mcp-client/client-registration-api.md) scripts the registration step.
* [JWT-SVID](/agentic-access/using-the-gateway/spiffe-svid.md): authenticate an unattended workload to the gateway with a SPIFFE JWT-SVID instead of an interactive sign-in.
* [OAuth servers from a headless agent](/agentic-access/using-the-gateway/headless-oauth-credentials.md): sign in once for an unattended agent, so it can call an MCP server that uses OAuth.
* [Requesting access](/agentic-access/using-the-gateway/requesting-access.md): how an agent requests, checks, uses, and relinquishes just-in-time access to the servers and agents behind the gateway.
* [Use MCP servers with Claude Code](/agentic-access/using-the-gateway/using-mcp-servers.md): connect a Claude Code client to the servers behind the gateway with the P0 CLI.
