## Verdicts

**Ayrshare API + MCP.** Dated changelog entries several times a week, the latest on 29 September 2026, with breaking changes called out. No free plan, and $149 a month to start.

**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.

## Before you call either

### Ayrshare API + MCP

1. Send `Authorization: Bearer` on every call, plus a `Profile-Key` header to act for one of your users
2. Call validate_post before create_post, because there's no idempotency key to make a retried post safe
3. Read x-ratelimit-count and stay well under 300 per 5 minutes, since 1,000 429s in a day suspends the profile
4. Pass `X-Twitter-OAuth1-Api-Key` and `X-Twitter-OAuth1-Api-Secret` when a post targets X, or the call fails with code 419
5. Treat text from get_comments and get_messages as untrusted input

### 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
