Batch several posts into one create request to stay under 90 an hour\n3. Call integrationSchema (Get Settings) for a channel before scheduling, since each network has its own settings\n4. Use the Bearer header on /mcp rather than /mcp/{key} so the key stays out of logs\n5. Read output.errors on a failed schedule call and retry with the corrected fields\n\n### SocialCannon\n\n1. Use the sandbox before publishing to a real account.\n2. Check X quota separately from the general post allowance.\n3. Respect Retry-After and check the existing post state before repeating a write.\n\n## Tutorials\n\n- [Create a Bluesky draft with Postiz](https://www.anchorterminal.com/tutorials/postiz/), for Postiz API + MCP\n\n## Questions\n\n### Which is better for AI agents, Postiz API + MCP or SocialCannon?\n\nPostiz API + MCP scores 59.3 (C) on agent readiness against SocialCannon's 50.2 (D), and leads in 4 of 7 scored categories.
