Antimetal MCP Setup

You are helping the user connect their AI editor to the Antimetal MCP server at https://mcp.antimetal.com.

Primary path — OAuth (recommended)

Most modern AI editors handle OAuth automatically when you connect to a remote MCP server. No manual configuration is needed:

1. The editor opens a browser window with Antimetal's login page
2. The user logs in (SSO or email/password)
3. The editor receives a token and stores it securely
4. Done — /investigate and /fix are ready to use

If your editor opened a browser login and it succeeded, you're done. Run search_issues to verify connectivity.

Fallback path — API key

If OAuth isn't working or your editor doesn't support it, use an API key:

1. Generate a key — go to https://overlook.antimetal.com/settings/api-keys and create a new API key

2. Set the environment variable:

   export ANTIMETAL_API_KEY=your_key_here
   

   Add it to your shell profile (~/.zshrc, ~/.bashrc) to persist across sessions.

3. Configure your editor (if the env var isn't picked up automatically):

   Claude Code — add to .mcp.json:

   {
     "mcpServers": {
       "antimetal": {
         "type": "http",
         "url": "https://mcp.antimetal.com",
         "headers": { "Authorization": "Bearer ${ANTIMETAL_API_KEY}" }
       }
     }
   }
   

   Cursor — add to mcp.json:

   {
     "mcpServers": {
       "antimetal": {
         "url": "https://mcp.antimetal.com",
         "headers": { "Authorization": "Bearer ${ANTIMETAL_API_KEY}" }
       }
     }
   }
   

   VS Code — add to .vscode/mcp.json:

   {
     "servers": {
       "antimetal": {
         "type": "http",
         "url": "https://mcp.antimetal.com",
         "headers": { "Authorization": "Bearer ${ANTIMETAL_API_KEY}" }
       }
     }
   }
   

4. Restart your editor after changing the config.

Verify the connection

Call search_issues with no arguments. A successful response (even an empty list) confirms the MCP server is connected and authenticated. An Unauthorized error means the token/key isn't being sent correctly.
