Best for
  • Teams using multiple AI coding assistants
  • Organizations wanting to enforce API compatibility
  • Compliance workflows needing verifiable audit trails of AI changes
  • Teams that want an AI assistant to directly operate on GitHub repos and collaboration workflows
  • Users already in the GitHub Copilot ecosystem who want a zero-deployment remote option
Not for
  • Users not using AI coding tools
  • Teams seeking a full CI/CD replacement rather than a governance layer
  • Scenarios where you don't want the assistant to have write access to repos (enable only read-only toolsets)
  • Environments with strict network isolation for private repos that can't reach the official remote endpoint
Required permissions
  • Read repository files (for scanning, linting, diffing)
  • Write to local .git directory and .delimit directory (for hooks, configs, memory)
  • Execute commands (e.g., tests, security audit)
  • Network access (for model deliberation, cloud sync if enabled)
  • A personal access token (PAT) or OAuth App token; effective scope depends on the token's own permissions
  • Enabling toolsets like actions/issues/pull_requests grants write access — request tokens on a least-privilege basis
Risks and side effects
  • The server can execute code (e.g., tests, security audit), which could pose security risks.
  • Credentials or sensitive data could be stored in memory or ledger; ensure proper access control.
  • If cloud sync is enabled, event data may be sent to external services (user-provided Supabase).
  • Write toolsets (creating/merging PRs, triggering workflows) can cause accidental changes if the token is overscoped — try a read-only toolset first
  • In hosted mode, credentials travel via the Authorization header — make sure the client-to-api.githubcopilot.com connection is trusted
