Verdicts

Post Bridge API + MCP

Hosted MCP with OAuth 2.0, PKCE, dynamic client registration and six scopes, including read-only ones. Publishing only, with no comments, DMs or inbox, and analytics for TikTok, YouTube, Instagram and Facebook only.

Postiz API + MCP

AGPL-3.0 and self-hostable with the API and MCP included, 34 platforms. Create-post capped at 90 requests an hour on every Cloud plan.

Before you call either

Post Bridge API + MCP

  1. Call list_social_accounts first, upload media, then create_post. Omit scheduled_at to publish at once
  2. Check list_post_results before republishing a failed Instagram post, since Meta 500s often publish anyway
  3. Set is_draft true when a person should approve the post
  4. Put links for X in a reply, because captions sent to X lose their URLs
  5. Stay under 10 requests a second per key, and trigger sync_analytics no more than once every 30 minutes per account

Postiz API + MCP

  1. Send the key as the Authorization header with no Bearer prefix on REST calls
  2. Batch several posts into one create request to stay under 90 an hour
  3. Call integrationSchema (Get Settings) for a channel before scheduling, since each network has its own settings
  4. Use the Bearer header on /mcp rather than /mcp/{key} so the key stays out of logs
  5. Read output.errors on a failed schedule call and retry with the corrected fields
