Example MCP Tool Calls

List users:

  "params": {
    "name": "gam_list_users",
    "arguments": { "maxResults": 10 }
  }
}

Get user:

{
  "method": "tools/call",
  "params": {
    "name": "gam_get_user",
    "arguments": { "email": "user@example.com" }
  }
}

Create group:

{
  "method": "tools/call",
  "params": {
    "name": "gam_create_group",
    "arguments": { "groupEmail": "team@example.com", "groupName": "Team" }
  }
}

Troubleshooting

• GAM not found: Set GAM_PATH or add gam to your PATH.
• Authentication errors: Run gam oauth create.
• Quota/rate limit: Wait and retry; see Google Admin API quotas.
• Parameter validation: All inputs are validated; see error messages for details.

Security Considerations

• Only whitelisted GAM commands are allowed.
• All parameters are validated and sanitized.
• No arbitrary command execution.
• Logs redact sensitive data.
• Rate limiting and error handling are built-in.

Extending

Add new tools in src/tools/ and export them in src/tools/index.ts.
