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.

Post Bridge API + MCP

Hosted MCP with OAuth 2.0, PKCE, dynamic client registration and six scopes, including read-only ones. Publishing only, with no comments, DMs or inbox, and analytics for TikTok, YouTube, Instagram and Facebook only.

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

Post Bridge API + MCP

  1. Call list_social_accounts first, upload media, then create_post. Omit scheduled_at to publish at once
  2. Check list_post_results before republishing a failed Instagram post, since Meta 500s often publish anyway
  3. Set is_draft true when a person should approve the post
  4. Put links for X in a reply, because captions sent to X lose their URLs
  5. Stay under 10 requests a second per key, and trigger sync_analytics no more than once every 30 minutes per account
