API key in the query string on REST and in the MCP URL, with no scopes.\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### OneUp API + MCP\n\n1. Call listcategory, then listcategoryaccount, then schedule. Pass social_network_id as ALL to post to every account in a category\n2. Keep the ?apiKey= URLs out of logs and shared configs, and regenerate the key on the API Access page if one leaks\n3. Set requireApproval or isDraftPost true when a person should review before anything goes out\n4. Page through lists with start, 50 posts at a time\n5. Give dates as YYYY-MM-DD HH:MM with no timezone field, so confirm the account timezone first\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, OneUp API + MCP or X MCP?\n\nX MCP scores 55.4 (C) on agent readiness against OneUp API + MCP's 24.4 (F), and leads in every scored category.\n\n### Do OneUp API + MCP and X MCP need an API key?\n\nOneUp API + MCP needs an API key. X MCP takes an API key or an OAuth sign-in.\n\n### Can an agent call OneUp API + MCP and X MCP without installing anything?\n\nYes. OneUp API + MCP has a hosted endpoint at https://www.oneupapp.io/api and X MCP at https://api.x.com/mcp.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/oneup-vs-x-mcp.json, and with the fewest tokens: https://www.anchorterminal.com/compare/oneup-vs-x-mcp.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"oneup\", \"b\": \"x-mcp\"}`.
