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.

Upload-Post API + MCP

Free plan with 2 profiles and 10 uploads a month, no card. One account key with no scopes, and the MCP's OAuth grants a single mcp.full scope.

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

Upload-Post API + MCP

  1. Send Authorization: Apikey <key> on REST. The MCP also takes Bearer
  2. Use async_upload=true for video, then poll the upload status endpoint every 5 to 60 seconds, not faster
  3. Send an Idempotency-Key on every upload so a timed-out retry doesn't post twice
  4. Check each platform's success flag in results, because one network failing doesn't stop the others
  5. Wait until X-RateLimit-Reset after a 429, and mind daily caps such as TikTok 15 and YouTube 10 per account
