## Which one, for what

### bundle.social (C)

Good for: A SaaS product or agent that manages many accounts for many customers, since paid plans do not charge per connected account and teams separate tenants.

Ahead on:
- Schema & documentation, 86 against 76
- Agent ergonomics, 66 against 53
- Payments & pricing, 35 against 10
- Maintenance & community, 78 against 63
- Transparency & trust, 65 against 48

Also in its favour:
- A hosted endpoint, with nothing to install
- Runs on your own machine
- Free to start without a card
- No incidents deducted, where Mixpost API + MCP loses 4 points for them

Watch for: API keys are organisation-wide with no scopes or read-only mode found, so one key reaches every team and connected account

### 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:
- Reliability, 70 against 63
- Security & auth, 43 against 34

Also in its favour:
- Open source

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

## Verdicts

**bundle.social.** The REST API has a public OpenAPI 3.0 description of 194 operations, Markdown docs and published rate limits, and the free plan needs no card. Organisation API keys carry no scopes, there is no idempotency key, and the status page shows one API outage of 4 hours 3 minutes on 31 August 2026.

**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.

## Before you call either

### bundle.social

1. Send the key in the `x-api-key` header to `https://api.bundle.social/api/v1`. A missing key returns 401 and a bad key 403
2. Pass `teamId` on most calls. Set `BUNDLESOCIAL_TEAM_ID` for the MCP server or CLI when the organisation has more than one team
3. Set a `referenceKey` on each post and look it up with the reference-key endpoint before retrying a create, because there is no idempotency key
4. Check `GET /api/v1/organization/usage/daily-limits` before bulk scheduling. Failed and deleted posts still count against the monthly quota
5. A person must complete each network's OAuth consent in a browser. Keep prepaid credit for X, where a post costs $0.015 or $0.20 with a link

### 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
