## Verdicts

**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.

**OneUp API + MCP.** API and MCP on every plan from $25 a month ($15 billed yearly). API key in the query string on REST and in the MCP URL, with no scopes.

## Before you call either

### 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

### OneUp API + MCP

1. Call listcategory, then listcategoryaccount, then schedule. Pass social_network_id as ALL to post to every account in a category
2. Keep the ?apiKey= URLs out of logs and shared configs, and regenerate the key on the API Access page if one leaks
3. Set requireApproval or isDraftPost true when a person should review before anything goes out
4. Page through lists with start, 50 posts at a time
5. Give dates as YYYY-MM-DD HH:MM with no timezone field, so confirm the account timezone first
