Which one, for what

Publer API + MCP D

Good for Agencies already on Publer Business who want an agent to schedule in bulk and read deep analytics, including competitors.

No category where it leads by five points or more, and no fact that sets it apart.

Watch for

API and MCP only on Business and Enterprise, and the free plan has no API

Sprout Social API C

Good for Reporting agents that pull profile, post, inbox, listening and case data for a company that already pays for Sprout Social, and for drafting posts a person will approve.

Watch for

Verdicts

Publer API + MCP

Scoped API keys (workspaces, accounts, posts, media, analytics) with 401 and 403 errors that name the missing scope or header. API and MCP only on Business and Enterprise, and the free plan has no API.

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

Publer API + MCP

  1. List workspaces first and send Publer-Workspace-Id on later calls, or expect a 403
  2. Poll /job_status/{job_id} after posts/schedule and read payload.failures, since status reads complete even when posts failed
  3. Use the Bearer-API scheme, not Bearer
  4. Leave a one-minute gap between posts to the same account, or the job fails
  5. Read X-RateLimit-Reset after a 429 and wait until then, as there's no Retry-After

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
