X quotas remain on paid plans with unlimited posts.\n\n## Before you call either\n\n### Post Bridge API + MCP\n\n1. Call list_social_accounts first, upload media, then create_post. Omit scheduled_at to publish at once\n2. Check list_post_results before republishing a failed Instagram post, since Meta 500s often publish anyway\n3. Set is_draft true when a person should approve the post\n4. Put links for X in a reply, because captions sent to X lose their URLs\n5. Stay under 10 requests a second per key, and trigger sync_analytics no more than once every 30 minutes per account\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## Questions\n\n### Which is better for AI agents, Post Bridge API + MCP or SocialCannon?\n\nSocialCannon scores 50.2 (D) on agent readiness against Post Bridge API + MCP's 48.3 (D), and leads in 5 of 7 scored categories.
