🖥️ Claude Desktop Integration

AgentExecMCP works seamlessly with Claude Desktop using SSE transport. This is perfect for local development and testing.

Easy Setup with Make (Recommended)

Super simple 3-step setup:

1. Start AgentExecMCP:

make quick-start

2. Install Claude Desktop configuration:

make install-claude-config

3. Restart Claude Desktop and look for the MCP tools icon! 🎉

Manual Setup (if you prefer)

1. Start the SSE server:

docker run -d --name AgentExecMCP-claude -p 8000:8000 -e MCP_TRANSPORT=sse AgentExecMCP

2. Configure Claude Desktop:

Open your Claude Desktop configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

Add the following configuration:

{
     "mcpServers": {
       "AgentExecMCP": {
         "command": "npx",
         "args": [
           "mcp-remote",
           "http://localhost:8000/sse"
         ]
       }
     }
   }

3. Restart Claude Desktop and look for the MCP tools icon

Test the Integration

Try these commands in Claude Desktop:

• "Run a shell command to list files"
• "Execute some Python code to calculate 2+2"
• "Install the requests package using pip"

Troubleshooting

• Check server status: make status
• View logs: make logs
• Restart server: make stop && make quick-start

Prerequisites for Claude Desktop

• Node.js and npm installed on your system
• Docker running with the AgentExecMCP container
• Claude Desktop latest version

The mcp-remote package will be automatically installed by npx when first used.

🖥️ Cursor Integration

AgentExecMCP works seamlessly with the Cursor IDE using the same SSE transport and configuration as Claude Desktop.

Manual Setup (for Cursor)

1. Start the SSE server:

make quick-start

2. Configure Cursor:

Open your Cursor mcp configuration file (for example ~/.cursor/mcp.json) and add the following:

{
     "mcpServers": {
       "AgentExecMCP": {
         "command": "npx",
         "args": [
           "mcp-remote",
           "http://localhost:8000/sse"
         ]
       }
     }
   }

🔧 MCP Tools

1. Shell Tool

Execute shell commands with safety controls.

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "shell",
    "arguments": {
      "request": {
        "command": "echo 'Hello World!'",
        "timeout": 60,
        "cwd": "/workspace"
      }
    }
  }
}

2. Execute Code Tool

Run code snippets in Python, Node.js, or Go with optimized execution.

{
  "jsonrpc": "2.0",
  "id": 2,
  "method": "tools/call",
  "params": {
    "name": "execute_code",
    "arguments": {
      "request": {
        "language": "python",

        "timeout": 60
      }
    }
  }
}

Features:

• Python: Full Python 3.x environment with standard library
• Node.js: Node.js runtime with npm packages

        "version": "2.32.0"
      }
    }
  }
}

🌐 Client Connection Examples

FastMCP Client (Python)

from fastmcp import Client
import asyncio

async def main():
    # Connect via stdio to local container
    async with Client("docker run -i --rm AgentExecMCP") as client:
        result = await client.call_tool("shell", {"request": {"command": "echo 'Hello!'"}})
        print(result[0].text)
    
    # Connect via SSE to HTTP server
    async with Client("http://localhost:8000/sse") as client:
        tools = await client.list_tools()
        print(f"Available tools: {[tool.name for tool in tools]}")

asyncio.run(main())

🔒 Security Features

# Run server with SSE transport
MCP_TRANSPORT=sse uv run python -m app.main

Testing

The server has been tested with:

• ✅ MCP protocol compliance across all transports
• ✅ All three tools (shell, execute_code, install_package)
• ✅ Multi-language code execution with package imports
• ✅ Package installation and verification
• ✅ Docker container deployment
• ✅ Claude Desktop integration via SSE transport
• ✅ Safety and timeout controls

📋 Requirements

• Docker (for containerized deployment)
