## 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.

**Publer API + MCP.** Scoped API keys (workspaces, accounts, posts, media, analytics) with 401 and 403 errors that name the missing scope or header. API and MCP only on Business and Enterprise, and the free plan has no API.

## 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

### Publer API + MCP

1. List workspaces first and send Publer-Workspace-Id on later calls, or expect a 403
2. Poll /job_status/{job_id} after posts/schedule and read payload.failures, since status reads complete even when posts failed
3. Use the Bearer-API scheme, not Bearer
4. Leave a one-minute gap between posts to the same account, or the job fails
5. Read X-RateLimit-Reset after a 429 and wait until then, as there's no Retry-After
