## 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
