Blotato vs Mixpost API + MCP

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.

Mixpost API + MCP

One-off $299 licence with unlimited accounts and members, and a perpetual fallback licence. No API or MCP in the free Lite edition.

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

Mixpost API + MCP

1. Call list-workspaces first. Workspace endpoints sit under /api/{workspaceUuid}
2. Check MIXPOST_CORE_PATH. It's empty by default from Pro v7 but defaults to mixpost in older versions and Lite
3. Create the token as a Viewer-role user when the agent only needs to read
4. Use unschedule-post rather than delete-post when a person wants a post pulled back to draft
5. Expect HTTP 422 with an errors.limit entry when a Cloud plan limit is hit
