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.

Upload-Post API + MCP

Free plan with 2 profiles and 10 uploads a month, no card. One account key with no scopes, and the MCP's OAuth grants a single mcp.full scope.

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

Upload-Post API + MCP

  1. Send Authorization: Apikey <key> on REST. The MCP also takes Bearer
  2. Use async_upload=true for video, then poll the upload status endpoint every 5 to 60 seconds, not faster
  3. Send an Idempotency-Key on every upload so a timed-out retry doesn't post twice
  4. Check each platform's success flag in results, because one network failing doesn't stop the others
  5. Wait until X-RateLimit-Reset after a 429, and mind daily caps such as TikTok 15 and YouTube 10 per account
