## 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.

**Postiz API + MCP.** AGPL-3.0 and self-hostable with the API and MCP included, 34 platforms. Create-post capped at 90 requests an hour on every Cloud plan.

## 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

### Postiz API + MCP

1. Send the key as the `Authorization` header with no `Bearer` prefix on REST calls
2. Batch several posts into one create request to stay under 90 an hour
3. Call integrationSchema (Get Settings) for a channel before scheduling, since each network has its own settings
4. Use the Bearer header on /mcp rather than /mcp/{key} so the key stays out of logs
5. Read output.errors on a failed schedule call and retry with the corrected fields
