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.

SocialCannon

Scoped credentials and published rate limits. X quotas remain on paid plans with unlimited posts.

Before you call either

Metricool API + MCP

  1. Connect the hosted MCP at https://ai.metricool.com/mcp with OAuth, and ask only for mcp:read when the job is reporting
  2. Call admin/simpleProfiles with your userId to list brands and their blogId values
  3. Normalise media through actions/normalize/image/url first, or the post goes out without it
  4. Give publicationDate a dateTime and an IANA timezone, in the future
  5. Back off on your own, since no rate limits or Retry-After are documented

SocialCannon

  1. Use the sandbox before publishing to a real account.
  2. Check X quota separately from the general post allowance.
  3. Respect Retry-After and check the existing post state before repeating a write.
