API and MCP only on Business and Enterprise, and the free plan has no API.\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### Publer API + MCP\n\n1. List workspaces first and send Publer-Workspace-Id on later calls, or expect a 403\n2. Poll /job_status/{job_id} after posts/schedule and read payload.failures, since status reads complete even when posts failed\n3. Use the Bearer-API scheme, not Bearer\n4. Leave a one-minute gap between posts to the same account, or the job fails\n5. Read X-RateLimit-Reset after a 429 and wait until then, as there's no Retry-After\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## Questions\n\n### Which is better for AI agents, Publer API + MCP or X MCP?\n\nX MCP scores 55.4 (C) on agent readiness against Publer API + MCP's 46.8 (D), and leads in 6 of 7 scored categories. Publer API + MCP leads on agent ergonomics.\n\n### Do Publer API + MCP and X MCP need an API key?\n\nPubler API + MCP needs an API key. X MCP takes an API key or an OAuth sign-in.\n\n### Can an agent call Publer API + MCP and X MCP without installing anything?\n\nYes.
