MCP Integration

The traitclaw-mcp crate implements the Model Context Protocol client, enabling your agent to discover and use tools from MCP servers.

Quick Start

use traitclaw_mcp::{McpServer, McpToolRegistry};

// Connect to an MCP server via stdio
let server = McpServer::stdio("npx", &["-y", "@mcp/server-filesystem", "."]).await?;

// Convert MCP tools to TraitClaw tools
let registry = McpToolRegistry::from_server(server).await?;

let agent = Agent::builder()
    .provider(provider)
    .tool_registry(registry)
    .build()?;

// The agent can now use all tools from the MCP server!

Multi-Server

use traitclaw_mcp::MultiServerMcpRegistry;

let registry = MultiServerMcpRegistry::new()
    .add_server("fs", McpServer::stdio("npx", &["-y", "@mcp/server-filesystem", "."]).await?)
    .add_server("db", McpServer::stdio("npx", &["-y", "@mcp/server-postgres", db_url]).await?)
    .build()
    .await?;
