No API or MCP in the free Lite edition.\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### Mixpost API + MCP\n\n1. Call list-workspaces first. Workspace endpoints sit under /api/{workspaceUuid}\n2. Check MIXPOST_CORE_PATH. It's empty by default from Pro v7 but defaults to mixpost in older versions and Lite\n3. Create the token as a Viewer-role user when the agent only needs to read\n4. Use unschedule-post rather than delete-post when a person wants a post pulled back to draft\n5. Expect HTTP 422 with an errors.limit entry when a Cloud plan limit is hit\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, Mixpost API + MCP or X MCP?\n\nX MCP scores 55.4 (C) on agent readiness against Mixpost API + MCP's 49.5 (D), and leads in 5 of 7 scored categories. Mixpost API + MCP leads on schema \u0026 documentation and agent ergonomics.\n\n### Do Mixpost API + MCP and X MCP need an API key?\n\nMixpost API + MCP needs an access token. X MCP takes an API key or an OAuth sign-in.\n\n### Can an agent call Mixpost API + MCP and X MCP without installing anything?\n\nNo hosted endpoint is listed for Mixpost API + MCP. X MCP has a hosted endpoint at https://api.x.com/mcp.\n\n### Are Mixpost API + MCP and X MCP open source?\n\nMixpost API + MCP is open source (proprietary (Pro and Enterprise, which carry the API and MCP), MIT (Lite)). No open-source release is listed for X MCP.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/mixpost-vs-x-mcp.json, and with the fewest tokens: https://www.anchorterminal.com/compare/mixpost-vs-x-mcp.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"mixpost\", \"b\": \"x-mcp\"}`.
