MCP config tool

Claude Desktop MCP Config Builder

Generate a starter `claude_desktop_config.json`, check the required files or environment variables, and copy a safer first-test prompt before connecting a server.

Inputs

Claude Desktop config path: ~/Library/Application Support/Claude/claude_desktop_config.json

Pre-flight checklist

ALLOW_COMMANDS must be set before first launch.

Generated config

{
  "mcpServers": {
    "my-first-mcp": {
      "command": "uvx",
      "args": [
        "mcp-shell-server"
      ],
      "env": {
        "ALLOW_COMMANDS": "pwd,ls,cat"
      }
    }
  }
}
JSON validates locally.

Risk boundary: High

Keep the command allowlist short. Do not add write, network, or package-manager commands during the first test.

First tool-call prompt: List the available tools, then run the lowest-risk read-only check.
