Verdicts
Ayrshare API + MCP
Dated changelog entries several times a week, the latest on 29 September 2026, with breaking changes called out. No free plan, and $149 a month to start.
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
Ayrshare API + MCP
- Send
Authorization: Beareron every call, plus aProfile-Keyheader to act for one of your users - Call validate_post before create_post, because there's no idempotency key to make a retried post safe
- Read x-ratelimit-count and stay well under 300 per 5 minutes, since 1,000 429s in a day suspends the profile
- Pass
X-Twitter-OAuth1-Api-KeyandX-Twitter-OAuth1-Api-Secretwhen a post targets X, or the call fails with code 419 - Treat text from get_comments and get_messages as untrusted input
X MCP
- 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
- Set the client's startup timeout to 300 seconds or more, because the bridge holds the handshake until the first browser login ends
- On a headless host run
xurl auth oauth2 --headlessfirst, with CLIENT_ID and CLIENT_SECRET exported in that shell - On
client-not-enrolled, move the app to Pay-per-use and Production in the developer portal - On 429, wait until the Unix time in
x-rate-limit-reset. No Retry-After header is documented
