agentic-mcp

MCP (Model Context Protocol) client for the Agentic Framework.

Features

• MCP Client: Connect to MCP servers
• Tool Execution: Call MCP tools from agents
• Code Mode: Agents write code that calls MCP tools (98.7% token reduction)
• Async-first: Built on Tokio

Installation

[dependencies]
agentic-mcp = "0.1"

Quick Start

use dasein_agentic_mcp::{MCPClientPool, MCPConfig};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let config = MCPConfig {
        servers: vec![
            MCPServerConfig {
                name: "sql".into(),
                url: "http://localhost:8080".into(),
                transport: TransportType::Http,
            }
        ],
    };

    let pool = MCPClientPool::new(config).await?;

    let result = pool.call("sql", "execute_sql", json!({
        "sql": "SELECT * FROM users"
    })).await?;

    println!("{:?}", result);

    Ok(())
}

Code Mode

Instead of passing tool schemas to LLMs (expensive), agents write Python code:

# Agent writes this code, executed in sandbox
result = mcp.call("execute_sql", {"sql": "SELECT * FROM users"})
print(result)

Benefits:

• 98.7% token reduction vs function calling
• More complex tool compositions
• Agents can use loops, conditions, error handling
