## Which one, for what

### Blotato (D)

Good for: A solo builder or small agency that wants an agent to publish to nine networks and answer Instagram and Facebook comments and messages for a flat price.

Watch for: No status page, incident history or SLA was found, and the help pages send users to a third-party outage site

### Upload-Post API + MCP (C)

Good for: Video-heavy publishing to TikTok, Reels and Shorts at a low price, and for white-label products that link end users through JWT connect pages.

Ahead on:
- Reliability, 57 against 38
- Agent ergonomics, 72 against 57
- Payments & pricing, 30 against 10
- Maintenance & community, 79 against 65
- Transparency & trust, 70 against 45

Also in its favour:
- Runs on your own machine
- Free to start without a card

Watch for: One account key with no scopes, and the MCP's OAuth grants a single mcp.full scope

## 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.

**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

### 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

### 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
