| 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
| - Developers auditing NPM dependencies within AI workflows
- Teams performing supply chain security assessments
- Users of Claude Desktop, Cursor, or VS Code
|
|---|
| 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)
| - Projects outside the NPM ecosystem (e.g., pure Python/Go)
- Environments without network access to deps.dev, OSV.dev, and the npm registry
- Scenarios requiring maintenance by an official upstream vendor
|
|---|
| 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
| - Network access to the NPM registry and external services (deps.dev, OSV.dev, OpenSSF, npms.io, GitHub)
- Read access to workspace lockfiles (pnpm-lock.yaml, package-lock., yarn.lock) for cache invalidation
|
|---|
| 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
| - Third-party READMEs and changelogs are untrusted external content; they are wrapped in tags with _meta flags but should still be handled cautiously
- Depends on availability and accuracy of external services
- Batch requests are capped at 25 packages to prevent registry enumeration; larger sets require batching
- Third-party open source project, not officially maintained by NPM or Anthropic
