# agent_mcp

**MCP-style bridge** for the agent surface: JSON-RPC over a backend-neutral
`agent_core::Backend` vtable, gated by `AuthGate` on the **External** channel.
Transports include newline-delimited JSON over Unix-domain sockets and a
loopback HTTP endpoint used where a local socket is not the platform path.

```toml
[dependencies]
agent_mcp  = "*"
agent_core = "*"
json       = "*"
stdlib     = "*"
```

```cplus
import "agent_mcp/agent_mcp" as mcp;
import "agent_core/auth" as auth;
import "agent_core/events" as events;
import "agent_core/backend" as backend;
import "stdlib/text" as text;

// vt = backend.mcp_backend() from a platform agent backend
// surf = #addr_of(surface) as *u8
let line: str = "{\"jsonrpc\":\"2.0\",\"id\":1,\"method\":\"describe_ui\",\"params\":{}}";
let resp: text::Text = mcp::handle_request(surf, vt, sub, gate, line);
```
