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
