MCP GlitchTip

An MCP (Model Context Protocol) server that integrates GlitchTip error monitoring with AI assistants like Claude. This allows AI to analyze and help resolve errors from your GlitchTip instance.

What it does

This MCP server enables AI assistants to:

• Fetch and analyze current issues from your GlitchTip instance
• Get detailed error context including stack traces, user data, and breadcrumbs
• Help debug and suggest solutions based on error patterns

Example Use Case

User: "Check GlitchTip for any payment-related errors"

AI Assistant:
- Fetches all unresolved issues from GlitchTip
- Identifies payment component errors
- Analyzes stack traces and error patterns
- Suggests specific fixes based on the error context

Quick Start

1. Get Your GlitchTip Credentials

You'll need:

• Authentication: Either an API token (recommended) or Session ID Cookie
• Organization Slug: Your organization identifier in GlitchTip
• Base URL (optional): Your GlitchTip instance URL if self-hosted

Authentication Options

Option 1: API Token (Recommended)

1. Log in to your GlitchTip instance
2. Go to /profile/auth-tokens
3. Create a new API token with appropriate permissions
4. Copy the token for use as GLITCHTIP_TOKEN

Option 2: Session ID

1. Log in to your GlitchTip instance
2. Open browser developer tools (F12)
3. Go to Application/Storage > Cookies
4. Find the sessionid cookie value
5. Copy this value for use as GLITCHTIP_SESSION_ID

2. Configure Your Project

Create a .mcp.json file in your project root:

{
  "mcpServers": {
    "glitchtip": {
      "command": "npx",
      "args": ["-y", "mcp-glitchtip"],
      "env": {
        "GLITCHTIP_TOKEN": "your-api-token-here",
        "GLITCHTIP_ORGANIZATION": "your-org-slug",
        "GLITCHTIP_BASE_URL": "https://app.glitchtip.com"
      }
    }
  }
}

Note: Add .mcp.json to your .gitignore to keep credentials secure:

echo ".mcp.json" >> .gitignore

3. Open Your Project in Claude Desktop

When you open your project folder in Claude Desktop, it will automatically detect the .mcp.json configuration and connect to your GlitchTip instance.

Configuration Options

| Environment Variable | Required | Description | Default | | ------------------------ | -------- | ------------------------------------ | --------------------------- | | GLITCHTIP_TOKEN | Yes* | Your GlitchTip API token (recommended) | - | | GLITCHTIP_SESSION_ID | Yes* | Your GlitchTip session cookie | - | | GLITCHTIP_ORGANIZATION | Yes | Organization slug from GlitchTip URL | - | | GLITCHTIP_BASE_URL | No | GlitchTip instance URL | https://app.glitchtip.com |

*Either GLITCHTIP_TOKEN or GLITCHTIP_SESSION_ID is required. If both are provided, GLITCHTIP_TOKEN takes priority.

Example Workflows

Debugging a Production Error

User: "Check GlitchTip for recent 500 errors"

AI: [Fetches issues] I found 3 recent 500 errors:
1. DatabaseConnectionError in /api/users
2. TimeoutError in payment processing
3. ValidationError in checkout flow

User: "Show me details about the payment timeout"

AI: [Gets latest event] The TimeoutError occurs when...
[Provides stack trace analysis and suggested fixes]

Monitoring Error Trends

User: "What are the most frequent errors in GlitchTip?"

AI: [Analyzes issue counts] The top errors by frequency are:
1. CORS policy errors (145 occurrences)
2. Missing authentication token (89 occurrences)
3. Rate limit exceeded (67 occurrences)

Development

Building from Source

git clone https://github.com/coffebar/mcp-glitchtip.git
cd mcp-glitchtip
npm install
npm run build

Development Mode

npm run watch  # Auto-rebuild on changes

Testing with MCP Inspector

npm run inspector

Set the required environment variables before running the inspector:

export GLITCHTIP_TOKEN="your-api-token"
# OR export GLITCHTIP_SESSION_ID="your-session-id"
export GLITCHTIP_ORGANIZATION="your-org"
npm run inspector

Troubleshooting

Authentication Errors

If you see "Authentication failed. Check your token or session ID":

1. If using a token: Verify it's valid and has appropriate permissions
2. If using a session ID: Your session may have expired - get a new session ID from GlitchTip
3. Verify you're using the correct organization slug
4. Check if your GlitchTip instance requires additional authentication headers

Connection Errors

If you see "Failed to connect to GlitchTip":

1. Verify your GLITCHTIP_BASE_URL is correct
2. Check if you're behind a proxy or firewall
3. Ensure your GlitchTip instance is accessible from your network

No Issues Found

If the tool returns empty results:

1. Verify there are actually issues in your GlitchTip project
2. Check if your organization slug is correct
3. Ensure your session has permission to view the issues

Security Notes

• Never commit .mcp.json to version control - it contains sensitive credentials
• For team usage, each developer should use their own API token or session ID
