Verdicts
Metricool API + MCP
Hosted MCP with OAuth and separate mcp:read and mcp:write scopes, on every plan including Free. REST API only on Advanced ($67 a month) and Custom.
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
Metricool API + MCP
- Connect the hosted MCP at https://ai.metricool.com/mcp with OAuth, and ask only for mcp:read when the job is reporting
- Call admin/simpleProfiles with your userId to list brands and their blogId values
- Normalise media through
actions/normalize/image/urlfirst, or the post goes out without it - Give publicationDate a dateTime and an IANA timezone, in the future
- Back off on your own, since no rate limits or Retry-After are documented
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
