## 🚀 Quick Setup

Setting up the Bugsnag MCP server is simple and doesn't require any installation or downloading source code.

### For Cursor

1. Add the Bugsnag MCP server configuration:
   ```json
   {
     "mcpServers": {
       "bugsnag": {
         "command": "npx",
         "args": ["-y", "bugsnag-mcp-server"],
         "env": {
           "BUGSNAG_API_KEY": "your-bugsnag-api-key"
         },
         "disabled": false,
         "alwaysAllow": []
       }
     }
   }
   ```

2. Replace `your-bugsnag-api-key` with your Bugsnag API key

### For Claude Desktop

1. Add the Bugsnag MCP server configuration:
   ```json
   {
     "mcpServers": {
       "bugsnag": {
         "command": "npx",
         "args": ["-y", "bugsnag-mcp-server"],
         "env": {
           "BUGSNAG_API_KEY": "your-bugsnag-api-key"
         },
         "disabled": false,
         "alwaysAllow": []
       }
     }
   }
   ```

2. Replace `your-bugsnag-api-key` with your Bugsnag API key

## 🔑 Obtaining a Bugsnag API Key

To use this MCP server, you'll need a Bugsnag API key:

1. Log in to your Bugsnag account at [https://app.bugsnag.com/](https://app.bugsnag.com/)
2. Go to **Settings** > **Organization settings** > **Access tokens**
3. Create a new personal access token with the following permissions:
   - Read projects
   - Read and write errors
   - Read and write comments
4. Copy the generated token for use with the MCP server

## 📋 Usage Examples
