## Verdicts

**Blotato.** One paid account gives an agent a REST API with a public OpenAPI document and an MCP server with 36 tools, with request limits and error codes documented in detail. No status page, changelog, security contact or free API access was found, and each account has a single key with full access.

**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.

## Before you call either

### Blotato

1. Call `blotato_list_accounts` or `GET /v2/users/me/accounts` first, and fetch `pageId` or `boardId` before posting to a Facebook Page, LinkedIn company Page or Pinterest
2. Keep the `postSubmissionId` and poll the status until `published`, `scheduled` or `failed`. It is a receipt, not proof of publication
3. After a timeout on a create call, list existing posts before sending again, because there is no idempotency key
4. Do not generate an API key on a trial account unless the owner accepts the Starter charge
5. Keep REST bodies and MCP arguments apart. REST nests `post.content` and `post.target`, and the MCP tool takes flat arguments

### 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
