## Which one, for what

### Mixpost API + MCP (D)

Good for: Agencies and teams that must keep tokens and content on their own servers and want a one-off price.

Ahead on:
- Schema & documentation, 76 against 51
- Maintenance & community, 63 against 38

Also in its favour:
- Open source

Watch for: No API or MCP in the free Lite edition

### 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.

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:
- A hosted endpoint, with nothing to install
- No incidents deducted, where Mixpost API + MCP loses 4 points for them

Watch for: Posts can be created only as drafts (`is_draft: true`), so the API cannot publish or schedule a post without a person in Sprout

## 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
