Unhook MCP Server

Use Unhook’s webhook data through the Model Context Protocol A Model Context Protocol (MCP) server implementation that integrates Unhook for webhook debugging and analysis capabilities. Our MCP server provides access to your webhook events, requests, and analytics through AI assistants like Claude and Cursor.

Features

Webhook event monitoring and analysis
Request inspection and debugging
Performance metrics and failure analysis
Real-time webhook data access
Cloud and self-hosted support
SSE transport support

Installation

You can either use our remote hosted URL or run the server locally. Get your API key from your Unhook dashboard at https://unhook.sh/app/api-keys.

Remote hosted URL

https://unhook.sh/api/mcp/{YOUR_API_KEY}/sse

Running with npx

env UNHOOK_API_KEY=your-api-key npx -y @unhook/mcp-server

Manual Installation

npm install -g @unhook/mcp-server

Try out our MCP Server on MCP.so’s playground or integrate with your favorite AI assistant.

Configuration Examples

Basic Cloud Configuration

{
  "mcpServers": {
    "unhook": {
      "url": "https://unhook.sh/api/mcp/YOUR_API_KEY/sse",
      "transport": "sse"
    }
  }
}

Self-Hosted Configuration

{
  "mcpServers": {
    "unhook": {
      "command": "npx",
      "args": ["-y", "@unhook/mcp-server"],
      "env": {
        "UNHOOK_API_KEY": "your-api-key",
        "UNHOOK_API_URL": "https://api.your-domain.com"
      }
    }
  }
}

Running on Different Platforms

Running on Cursor

Add Unhook MCP server to Cursor

Manual Installation

Note: Requires Cursor version 0.45.6+ To configure Unhook MCP in Cursor v0.48.6:

Open Cursor Settings
Go to Features > MCP Servers
Click ”+ Add new global MCP server”
Enter the following code:

{
  "mcpServers": {
    "unhook": {
      "command": "npx",
      "args": ["-y", "@unhook/mcp-server"],
      "env": {
        "UNHOOK_API_KEY": "YOUR-API-KEY"
      }
    }
  }
}

To configure Unhook MCP in Cursor v0.45.6:

Open Cursor Settings
Go to Features > MCP Servers
Click ”+ Add New MCP Server”
Enter the following:
- Name: “unhook” (or your preferred name)
- Type: “command”
- Command: env UNHOOK_API_KEY=your-api-key npx -y @unhook/mcp-server

If you are using Windows and are running into issues, try cmd /c "set UNHOOK_API_KEY=your-api-key && npx -y @unhook/mcp-server"

Replace your-api-key with your Unhook API key. If you don’t have one yet, you can get it from https://unhook.sh/app/api-keys. After adding, refresh the MCP server list to see the new tools. The Composer Agent will automatically use Unhook MCP when appropriate, but you can explicitly request it by describing your webhook debugging needs.

Running on Windsurf

Add this to your ./codeium/windsurf/model_config.json:

{
  "mcpServers": {
    "mcp-server-unhook": {
      "command": "npx",
      "args": ["-y", "@unhook/mcp-server"],
      "env": {
        "UNHOOK_API_KEY": "YOUR_API_KEY"
      }
    }
  }
}

Running with SSE Mode

To run the server using Server-Sent Events (SSE) locally instead of the default stdio transport:

env SSE_LOCAL=true UNHOOK_API_KEY=your-api-key npx -y @unhook/mcp-server

Use the url: http://localhost:3000/sse or https://unhook.sh/api/mcp/{YOUR_API_KEY}/sse

Running on VS Code

For manual installation, add the following JSON block to your User Settings (JSON) file in VS Code. You can do this by pressing Ctrl + Shift + P and typing Preferences: Open User Settings (JSON).

{
  "mcp": {
    "inputs": [
      {
        "type": "promptString",
        "id": "apiKey",
        "description": "Unhook API Key",
        "password": true
      }
    ],
    "servers": {
      "unhook": {
        "command": "npx",
        "args": ["-y", "@unhook/mcp-server"],
        "env": {
          "UNHOOK_API_KEY": "${input:apiKey}"
        }
      }
    }
  }
}

Optionally, you can add it to a file called .vscode/mcp.json in your workspace. This will allow you to share the configuration with others:

{
  "inputs": [
    {
      "type": "promptString",
      "id": "apiKey",
      "description": "Unhook API Key",
      "password": true
    }
  ],
  "servers": {
    "unhook": {
      "command": "npx",
      "args": ["-y", "@unhook/mcp-server"],
      "env": {
        "UNHOOK_API_KEY": "${input:apiKey}"
      }
    }
  }
}

Running on Claude Desktop

Add this to the Claude config file:

{
  "mcpServers": {
    "unhook": {
      "url": "https://unhook.sh/api/mcp/{YOUR_API_KEY}/sse"
    }
  }
}

Rate Limiting and Performance

  ],
  "isError": true
}

Usage Examples

Debugging Failed Webhooks

Ask your AI assistant:

“Show me all failed webhook events from the last hour”
“Why are my Stripe webhooks failing?”
“Analyze the error patterns in my webhook requests”

Performance Analysis

Ask your AI assistant:

“What’s the average response time for my webhooks?”
“Which webhooks have the highest failure rate?”
“Generate a performance report for my payment webhooks”

Request Inspection

Ask your AI assistant:

“Show me the payload for event evt_123”
“What headers were sent with the last GitHub webhook?”
“Compare successful vs failed requests for my Clerk webhook”

Security

Authentication

All MCP requests require authentication via your Unhook API key
API keys are scoped to your organization’s data only
Never share your API key publicly

Data Access

MCP servers can only access data you have permission to view
All data transmission is encrypted over HTTPS
No webhook data is stored by the AI assistant

Best Practices

Use environment-specific API keys for development vs production
Rotate your API keys regularly
Review MCP access logs in your dashboard

Troubleshooting

Connection Issues

AI assistant can't connect to Unhook

Verify your configuration file syntax is valid JSON
Check that your API key is correct and not expired
Ensure you’re using HTTPS (not HTTP) in the URL
Restart your AI assistant after configuration changes

No webhook data appearing

Confirm you have webhooks configured in your dashboard
Check that your API key has the correct permissions
Verify you’re in the right organization
Try manually triggering a webhook to generate data

Authentication errors

Regenerate your API key in the dashboard
Ensure the API key is properly formatted in the configuration
Check for extra spaces or characters in the API key
Verify the API key hasn’t expired

Rate limiting issues

Check your current rate limits in the dashboard
Reduce the frequency of requests
Use pagination to limit data size
Contact support if you need higher limits

Performance

The MCP server limits responses to prevent overwhelming AI assistants:

Events: Maximum 100 per request
Requests: Maximum 100 per request
Use search filters to find specific data
Enable pagination for large datasets
