Verdicts

Upload-Post API + MCP

Free plan with 2 profiles and 10 uploads a month, no card. One account key with no scopes, and the MCP's OAuth grants a single mcp.full scope.

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

Upload-Post API + MCP

  1. Send Authorization: Apikey <key> on REST. The MCP also takes Bearer
  2. Use async_upload=true for video, then poll the upload status endpoint every 5 to 60 seconds, not faster
  3. Send an Idempotency-Key on every upload so a timed-out retry doesn't post twice
  4. Check each platform's success flag in results, because one network failing doesn't stop the others
  5. Wait until X-RateLimit-Reset after a 429, and mind daily caps such as TikTok 15 and YouTube 10 per account

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
