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.

Publer API + MCP

Scoped API keys (workspaces, accounts, posts, media, analytics) with 401 and 403 errors that name the missing scope or header. API and MCP only on Business and Enterprise, and the free plan has no API.

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

Publer API + MCP

  1. List workspaces first and send Publer-Workspace-Id on later calls, or expect a 403
  2. Poll /job_status/{job_id} after posts/schedule and read payload.failures, since status reads complete even when posts failed
  3. Use the Bearer-API scheme, not Bearer
  4. Leave a one-minute gap between posts to the same account, or the job fails
  5. Read X-RateLimit-Reset after a 429 and wait until then, as there's no Retry-After
