Preflight validation. 80 local rules check content before any platform receives the request, returning clear error details.
Idempotent writes. Idempotency-Key ensures safe retries for up to 24 hours without duplicate posts.
Reviewed OAuth apps. Meta and LinkedIn app reviews are handled by letmepost, so you connect via a ready-to-use OAuth flow.
Open source & self-hostable. Apache-2.0 code; you can run the same image yourself with BYO Postgres + Redis.
Native MCP server. MCP endpoint and CLI let AI agents drive the full API surface directly.
Flat per-org pricing. Charges are based only on published posts, not per profile or seat.

Zero-storage architecture. Tool calls fetch data directly from source APIs; no data is cached or stored.
Authorization-first access. All tools require explicit customer authorization before they become callable.
