## 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

### Buffer API + MCP (B)

Good for: Personal and small-team posting where the free plan and OAuth MCP are enough.

Ahead on:
- Reliability, 55 against 38
- Agent ergonomics, 65 against 57
- Security & auth, 56 against 29
- Payments & pricing, 30 against 10
- Maintenance & community, 73 against 65
- Transparency & trust, 75 against 45

Also in its favour:
- Free to start without a card

Watch for: 22 status incidents between 6 July and 25 September 2026, several of them hours long

## 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.

**Buffer API + MCP.** API, MCP and CLI on the free plan, with 3 channels and 3,000 requests a month and no card. 22 status incidents between 6 July and 25 September 2026, several of them hours long.

## 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

### Buffer API + MCP

1. Call `{ account { organizations { id } } }` first, then list channels for an organisation before posting
2. Include `... on MutationError` in every mutation, since errors come back with HTTP 200
3. On 429, wait Retry-After plus a few seconds of jitter. The 429 itself doesn't cost quota
4. Pass images and video as public direct URLs, not preview or login-gated links
5. Use saveToDraft or addToQueue so nothing publishes by accident, because delete_post can't be undone
