      "command": "uvx",
      "args": [
        "webhook-mcp-server"
      ]

03 · What Webhook.site MCP Server can do

What you can build

With this server connected, an agent can check this server's setup: API key, account reachability, plan, real-time socket, env config, create a disposable inbox to sign up on a website: HTTP URL, temp email, DNS, create a webhook with custom settings, or update one (pass webhook_token), and read the temp inbox to sign up, verify, magic-link, or reset a password.
