## Which one, for what

### SocialCannon (D)

Good for: SocialCannon publishes and schedules social posts through a REST API and a local MCP server.

Ahead on:
- Agent ergonomics, 80 against 45
- Security & auth, 65 against 48
- Payments & pricing, 30 against 20

Watch for: X quotas remain on paid plans with unlimited posts

### 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 45
- Schema & documentation, 65 against 55
- Maintenance & community, 70 against 0
- Transparency & trust, 70 against 47

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

## Verdicts

**SocialCannon.** Scoped credentials and published rate limits. X quotas remain on paid plans with unlimited posts.

**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

### SocialCannon

1. Use the sandbox before publishing to a real account.
2. Check X quota separately from the general post allowance.
3. Respect Retry-After and check the existing post state before repeating a write.

### 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
