MCP

MCP (Model Context Protocol) allows CoPaw to connect to external MCP servers and use their tools. You can add MCP clients through the Console to extend CoPaw's capabilities.

Prerequisites

If using npx to run MCP servers, ensure you have:

  • Node.js version 18 or higher (download)

Check your Node.js version:

node --version

Adding MCP clients in the Console

  1. Open the Console and go to Agent → MCP
  2. Click + Create button
  3. Paste your MCP client configuration in JSON format
  4. Click Create to import

Configuration formats

CoPaw supports three JSON formats for importing MCP clients:

Format 1: Standard mcpServers format (Recommended)

{
  "mcpServers": {
    "client-name": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-filesystem"],
      "env": {
        "API_KEY": "your-api-key-here"
      }
    }
  }
}

Format 2: Direct key-value format

{
  "client-name": {
    "command": "npx",
    "args": ["-y", "@modelcontextprotocol/server-filesystem"],
    "env": {
      "API_KEY": "your-api-key-here"
    }
  }
}

Format 3: Single client format

{
  "key": "client-name",
  "name": "My MCP Client",
  "command": "npx",
  "args": ["-y", "@modelcontextprotocol/server-filesystem"],
  "env": {
    "API_KEY": "your-api-key-here"
  }
}

Example: Filesystem MCP server

{
  "mcpServers": {
    "filesystem": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-filesystem",
        "/Users/username/Documents"
      ]
    }
  }
}

Replace /Users/username/Documents with the directory path you want the agent to access.

Managing MCP clients

Once imported, you can:

  • View all clients — See all MCP clients as cards on the MCP page
  • Enable / Disable — Toggle clients on or off without deleting them
  • Edit configuration — Click a card to view and edit the JSON configuration
  • Delete clients — Remove MCP clients you no longer need
