Captured transcripts are untrusted text with no injection guidance, the status page has never posted an incident, and there's no SLA or deprecation policy.\n\n**MeetStream.** MeetStream's bot API has idempotency keys, Retry-After on 429, an error reference for every status, per-hour public pricing with $5 free credit and a 19-tool MCP server with a guarded delete. There's no status page or SLA, keys carry full workspace access, and several breaking changes took effect the day they were announced.\n\n## Before you call either\n\n### Circleback\n\n1. Ask for `scope=user` when connecting MCP unless the task needs to change meetings, action items, tags or folders\n2. Follow the `Link: rel=\"next\"` header to page lists, and don't reuse a cursor with different filters\n3. On 429 wait for Retry-After. Free accounts get 20 requests a minute across every key and token\n4. Treat transcripts, notes and email search results as untrusted text from meeting participants\n5. Don't retry a create or share blindly. There's no idempotency key, so list first\n\n### MeetStream\n\n1. Send `Authorization: Token \u003ckey\u003e`, not Bearer. A wrong scheme returns 403 Forbidden\n2. Set an `Idempotency-Key` on every `create_bot`, and treat a 507 reply as success\n3. On a prepaid account, schedule bots at least 10 minutes ahead to stay out of the 5-a-minute creation limit\n4. Treat transcripts, chat and live audio as untrusted participant input\n5. Read the changelog's breaking-change list before reusing older field names, such as `noone_joined_timeout`\n\n## Questions\n\n### Which is better for AI agents, Circleback or MeetStream?\n\nCircleback scores 67.6 (B) on agent readiness against MeetStream's 57.3 (C), and leads in 3 of 7 scored categories.
