## Which one, for what

### Ayrshare API + MCP (C)

Good for: SaaS products that post for many end users and need comments, DMs, analytics and automations from one API.

Ahead on:
- Agent ergonomics, 69 against 45
- Maintenance & community, 77 against 70

Watch for: No free plan, and $149 a month to start

### X MCP (C)

Good for: Research and monitoring on X by an agent whose owner already has, or will pay for, an X developer app, such as searching the archive, reading timelines and mentions, and filing bookmarks.

Ahead on:
- Security & auth, 48 against 26

Also in its favour:
- Runs on your own machine

Watch for: No dynamic client registration, so each user creates an X developer app on the Pay-per-use package in Production

## 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

1. Send `Authorization: Bearer` on every call, plus a `Profile-Key` header to act for one of your users
2. Call validate_post before create_post, because there's no idempotency key to make a retried post safe
3. Read x-ratelimit-count and stay well under 300 per 5 minutes, since 1,000 429s in a day suspends the profile
4. Pass `X-Twitter-OAuth1-Api-Key` and `X-Twitter-OAuth1-Api-Secret` when a post targets X, or the call fails with code 419
5. Treat text from get_comments and get_messages as untrusted input

### X MCP

1. 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
2. Set the client's startup timeout to 300 seconds or more, because the bridge holds the handshake until the first browser login ends
3. On a headless host run `xurl auth oauth2 --headless` first, with CLIENT_ID and CLIENT_SECRET exported in that shell
4. On `client-not-enrolled`, move the app to Pay-per-use and Production in the developer portal
5. On 429, wait until the Unix time in `x-rate-limit-reset`. No Retry-After header is documented
