X quotas remain on paid plans with unlimited posts.\n\n**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.\n\n## Before you call either\n\n### SocialCannon\n\n1. Use the sandbox before publishing to a real account.\n2. Check X quota separately from the general post allowance.\n3. Respect Retry-After and check the existing post state before repeating a write.\n\n### X MCP\n\n1. 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\n2. Set the client's startup timeout to 300 seconds or more, because the bridge holds the handshake until the first browser login ends\n3. On a headless host run `xurl auth oauth2 --headless` first, with CLIENT_ID and CLIENT_SECRET exported in that shell\n4. On `client-not-enrolled`, move the app to Pay-per-use and Production in the developer portal\n5. On 429, wait until the Unix time in `x-rate-limit-reset`. No Retry-After header is documented\n\n## Tutorials\n\n- [Research product mentions with X MCP](https://www.anchorterminal.com/tutorials/x-mcp/), for X MCP\n\n## Questions\n\n### Which is better for AI agents, SocialCannon or X MCP?\n\nX MCP scores 55.4 (C) on agent readiness against SocialCannon's 50.2 (D), and leads in 4 of 7 scored categories. SocialCannon leads on agent ergonomics, security \u0026 auth and payments \u0026 pricing.\n\n### Do SocialCannon and X MCP need an API key?\n\nSocialCannon uses an OAuth sign-in. X MCP takes an API key or an OAuth sign-in.\n\n### Can an agent call SocialCannon and X MCP without installing anything?\n\nYes.
