## 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 65
- Agent ergonomics, 66 against 45
- Payments & pricing, 35 against 20
- Maintenance & community, 78 against 70

Also in its favour:
- Free to start without a card

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

### X MCP (C)

Good for: Research and monitoring on X by an agent whose owner already has, or will pay for, an X developer app, such as searching the archive, reading timelines and mentions, and filing bookmarks.

Ahead on:
- Reliability, 72 against 63
- Security & auth, 48 against 34
- Transparency & trust, 70 against 65

Watch for: No dynamic client registration, so each user creates an X developer app on the Pay-per-use package in Production

## 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.

**X MCP.** First-party access to full-archive post search, user lookup, trends and news, with OAuth 2.0 PKCE scopes and per-resource prices published without a login. Every user must create a paid X developer app, the tool list isn't published, and the documented tools don't create posts.

## 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

### X MCP

1. Use the app-only Bearer header for read-only work. Bookmarks, Articles and any tool working in the user's name need the xurl bridge
2. Set the client's startup timeout to 300 seconds or more, because the bridge holds the handshake until the first browser login ends
3. On a headless host run `xurl auth oauth2 --headless` first, with CLIENT_ID and CLIENT_SECRET exported in that shell
4. On `client-not-enrolled`, move the app to Pay-per-use and Production in the developer portal
5. On 429, wait until the Unix time in `x-rate-limit-reset`. No Retry-After header is documented
