Ahead on

  • Agent ergonomics, 59 against 53
  • Security & auth, 61 against 43
  • Payments & pricing, 20 against 10
  • Transparency & trust, 70 against 48

Also in its favour

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.

Sprout Social API

The API reads analytics, inbox messages, listening topics and cases across the main networks, with OAuth client credentials, field selection and a dated changelog. It creates draft posts only, so a person must publish them in Sprout. Access needs the Advanced plan at $399 per seat a month, and no OpenAPI file or SDK was found.

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

Sprout Social API

  1. Call GET /v1/metadata/client first for the customer ID, then GET /v1/<customer ID>/metadata/customer for profile and group IDs. Every other path needs them
  2. Send is_draft: true on POST /v1/<customer ID>/publishing/posts. Tell the user the draft waits in the Sprout calendar for a person to publish
  3. Name the fields you want on messages and posts requests. Without the list only guid comes back
  4. Stay under 60 requests a minute and 250,000 a month, and back off on 429 on your own because no Retry-After is documented
  5. Check the response when a draft names several profiles. A profile that cannot take the attached media is dropped with no error
