| Best for | - Developers who want to develop Google Apps Script locally with their own editor and Git workflow
- Teams that need version control and collaboration for Apps Script projects
- Users who want an AI coding agent (Claude Code, Gemini CLI) to manage Apps Script projects directly
| - Developers using fast-moving frameworks/libraries worried about the AI suggesting stale code
- Scenarios wanting zero-config documentation lookup
| - 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 | - General cloud storage or database integrations unrelated to Apps Script
- Scenarios requiring vendor-backed official support SLAs (the README explicitly states it is not an officially supported Google product)
- Projects relying on clasp 2.x's built-in TypeScript transpilation (removed in 3.x — use a bundler like Rollup instead)
- Non-interactive service-account authentication (README marks this as experimental/not currently working)
| - Looking up internal/private codebase documentation (Context7 targets publicly published open-source libraries)
- Cases needing very high coverage of obscure, niche libraries (coverage depends on what Context7's platform has indexed)
| - 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 | - Google OAuth access to read/write the user's Apps Script projects (script.projects, script.deployments, script.webapp.deploy, etc.)
- Google Drive read-only metadata and file access (drive.metadata.readonly, drive.file) to list and create bound scripts
- Google Cloud Service Usage API access to list/enable/disable advanced services
- Cloud Logging read access to fetch script execution logs
- Local credential storage in `.clasprc.json` (containing OAuth tokens) in the home or working directory
| - Usable without an API key (subject to a free-tier rate limit); CONTEXT7_API_KEY is an optional credential for higher quota
- Read-only documentation lookup — no code execution or local filesystem access involved
| - 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 | - `clasp push` always replaces the entire remote project content (the Apps Script API has no atomic or per-file operations), so mistakes can overwrite remote code
- OAuth scopes are broad — covering scripts, Drive files, logging, and API management — so leaked credentials (especially custom ones saved via `--creds`) carry meaningful exposure
- MCP mode is explicitly experimental; the README states it currently offers only a limited tool subset and behavior may change
- Service-account / application-default-credentials support is explicitly marked experimental and 'NOT WORKING,' and should not be relied on for production automation
| - The free tier has limited quota — high-frequency use may hit rate limits
- Documentation content comes from Context7's platform index, so its accuracy and freshness depend on that platform's crawl cadence
| - 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
