agent-client-protocol-rmcp

rmcp integration for Agent Client Protocol MCP servers.

Overview

This crate bridges rmcp-based MCP server implementations with the ACP MCP server framework from agent-client-protocol. It lets you use any rmcp service as an MCP server in an ACP proxy.

Usage

Use the McpServerExt trait to create an MCP server from an rmcp service:

use agent_client_protocol::mcp_server::McpServer;
use agent_client_protocol_rmcp::McpServerExt;

let server = McpServer::from_rmcp("my-server", MyRmcpService::new);

// Use as a handler in a proxy
Proxy.builder()
    .with_mcp_server(server)
    .connect_to(transport)
    .await?;

Why a Separate Crate?

This crate is separate from agent-client-protocol to avoid coupling the core protocol crate to the rmcp dependency. This allows:

agent-client-protocol to remain focused on the ACP protocol
agent-client-protocol-rmcp to track rmcp updates independently
Breaking changes in rmcp only require updating this crate
