Real-Time API Context with MCP Server

The `get_requests` tool lets the agent pull actual data from a webhook token's history and inject it into your code. You get live payloads, not mock stubs. When writing functions that rely on external APIs, you can use this context to make sure your generated code handles real-world input variations.

Programmatic Webhook Management

Need a new endpoint for testing? Use `create_token` to generate a unique, fresh webhook URL. This token can then be used as context when generating API calls in your project. You'll also need the ability to manage variables; `list_global_variables` shows what context is already available to the AI.

Debug Code Logic with Webhook.site

The `execute_action` tool lets your agent run a series of defined steps against a specific webhook request. This proves that complex, multi-stage logic works exactly as expected in the code. If you need to adjust how the system responds programmatically, `set_response` updates the data source for the AI's generated functions.

Setup guide

Set up Webhook.site MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the Webhook.site MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent Webhook.site transactions." If the MCP tools are loaded correctly, Cursor will call the Webhook.site tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

{
  "mcpServers": {
    "webhooksite-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }
  }
}

Common questions about Webhook.site MCP in Cursor

You configure the MCP Server in your project scope, and then the agent can call `get_requests`. This pulls live payload data directly into the code you're writing, letting you test against real-world API responses.

The `delete_requests` tool handles this cleanup for you. If a token accumulates too many requests, you can purge them right from your coding environment's agent mode.

Yes. You use the server to create tokens for specific testing scenarios, allowing you to simulate interactions with sensitive APIs without needing local access while coding.

This server manages HTTP request payloads, token credentials (URLs), and global variable strings. Treat all payload data as potentially private when designing your application logic.

Absolutely. By creating different tokens and actions, you can simulate inputs from multiple sources or environments within the same coding session.
