Concrete capability record
Data, retrieval, actions, identity, and operating limits
A field-by-field summary of what the reviewed first-party references actually support. Publisher update dates and BYO-UI review dates are shown separately below.
02 · Data you can retrieve
Retrieve authorized/public video, channel, playlist, subscription, comment, caption, and live-streaming resources subject to quota and privacy rules.
03 · Actions and write paths
Upload, update, rate, moderate where supported, or delete videos; manage playlists, comments, captions, channel metadata, and live broadcasts/streams.
04 · Authentication and permissions
API keys identify projects for public-data requests; OAuth 2.0 scopes and user consent are required for private data and all insert, update, delete, or rating actions.
05 · Monitoring, approval, and recovery
Preserve creator identity, child-directed-content flags, rights and synthetic-media metadata, upload review, moderation policy, and quota/audit requirements.
06 · Limits and caveats
Every request consumes project quota; additional allocation requires a compliance audit, and periodic audits may be required to retain approved usage and continued access over time.

MCP support
Developer-context onlyAdjacent Google developer-context MCP; no YouTube operational provider
Support: Developer-context only
Read scope: No first-party MCP read surface verified.
Write scope: No first-party MCP write surface verified.
Authentication: Not applicable to a first-party MCP provider.
Approval boundary: Require explicit channel-owner confirmation before upload, privacy changes, metadata replacement, comment moderation, rating, live-event mutation, or deletion; show the acting channel and projected quota cost.
Protocol does not erase product boundaries.
Confirm the current tool catalog, plan, region, scopes, rate limits, terms, and write behavior before implementation.

The output could be an export, report, graph, artifact, application, agent, workflow, or downstream feed. These proposals are derived from documented access—not claims that Google ships them.
Single-platform patterns
- Channel content and performance command center
- Media production console
- Localization and variant studio
- Review-and-approval queue
Multi-platform compositions
- YouTube + publishing or campaign platform: media production console
- YouTube + DAM or CMS + social or video distribution system: cross-system decision workspace
Evidence and dates
First-party references, with publisher and review dates separated
“Publisher updated” is shown only when the page exposes an update date. “BYO-UI reviewed” records when this research checked the reference. A missing publisher date is reported as missing—not replaced with the review date.
