All limitations / Review context

Which transcript sources, languages, and tool behaviors are current?

The bounded assessment reviewed the official README, repository notices, security policy path, and security page for known material public-tracking blockers. No such blocker was identified. This is a public-tracking assessment, not an installation safety certification.

Read-oriented content retrieval.
Transcript is fetched remotely; optional direct-video analysis is sent to TwelveLabs.
Sensitive access: Public video/transcript content, Optional provider key
Installation, client compatibility and comprehensive security have not been independently audited. Authentication and access depend on the configured services.
A project-specific SECURITY.md policy was not available at the fetched official path; the review remains limited to published repository notices.
No installation, runtime, client matrix, or complete tool-contract audit was performed in this review.
The fetched official SECURITY.md path returned HTTP 404; it was not treated as positive evidence.
Optional analysis needs TWELVELABS_API_KEY.

Check connection
Suggested check
Retrieve a public test-video transcript only; do not invoke optional paid analysis.
Remove / uninstall / revoke
MCP100 setup guide
Use only when exact Claude Code registration is youtube-transcript; Smithery-installed client entry may have a different identifier—inspect host first.
Distinguish client registration removal from software uninstall, persistent data deletion and provider OAuth/API-key revocation.
