How to Set Up and Use Whistle Proxy Manager
Whistle MCP Server bridges AI assistants and the Whistle HTTP/HTTPS proxy, exposing 42 tools that cover rule management, group management, value management, proxy control, and request replay. With this server, you can instruct an AI to create or toggle proxy rules, intercept HTTPS traffic, replay captured requests, and manage named value groups — all without manually opening the Whistle web UI. It is particularly useful for developers who use Whistle for local network debugging and want AI-driven automation of their proxy configuration.
Prerequisites
- Node.js 18.20.0 or newer
- Whistle proxy installed and running locally (npm install -g whistle && w2 start)
- An MCP-compatible client such as Claude Desktop
- Optional: Whistle basic-auth credentials if your Whistle instance is password-protected
Install Whistle proxy
If you have not already done so, install Whistle globally and start it. By default it listens on port 8899.
npm install -g whistle
w2 startInstall the whistle-mcp-tool package
Install the MCP server package globally via npm. Alternatively use the Smithery CLI for one-step Claude Desktop setup.
npm install -g whistle-mcp-toolAdd the server to Claude Desktop configuration
Open claude_desktop_config.json and add the whistle-mcp server entry. If Whistle uses basic auth, provide --username and --password flags.
Restart Claude Desktop
After saving the configuration file, restart Claude Desktop to load the MCP server. The server connects to your local Whistle instance on startup.
Verify the connection
Ask the AI to retrieve the current Whistle status or list existing rules to confirm the server is connected and responding.

Client configuration
Claude Desktop configuration for the Whistle MCP server connecting to a local Whistle instance with optional basic auth.

}Prompts to try
Example prompts to control Whistle proxy via the AI assistant.
- "Show me all current Whistle proxy rules"
- "Create a rule that redirects api.example.com to localhost:3000"
- "Enable HTTPS interception in Whistle"
- "Replay the last intercepted request to /api/users"
- "Create a rule group called 'staging' and add my redirect rules to it"Troubleshooting Whistle Proxy Manager
MCP server cannot connect to Whistle
Ensure Whistle is running with w2 start and accessible at localhost:8899. Verify by opening http://localhost:8899 in a browser. If Whistle is on a different port, set --port accordingly.
Authentication errors when using basic auth
Pass your Whistle credentials using -n=username and -w=password flags in the args array. These must match the credentials configured in your Whistle instance.
whistle-mcp command not found after npm install
Run npm install -g whistle-mcp-tool again and ensure the global npm bin directory is in your PATH. Check with: npm config get prefix — add the bin subdirectory to your PATH.
