Write access here means flipping feature gates — genuinely useful for agents shipping code, and genuinely worth scoping the key for.
Read-only, which is right for session data — the value is giving an agent the replay context behind a bug report.
Official OAuth server with the cleanest auth story in analytics, but analysis-only — agents read charts, they don't change instrumentation.
Solid official read-only server — good for analysis sessions, not for changing tracking.
Official server exists, but it sits behind an enterprise contract — fine if you already pay for Pendo, not a starting point.
Biggest install base, worst setup: official but experimental, local-only, read-only, and gated behind Google Cloud auth.
