LithoBlocks API key obtained from your organization dashboard. The LithoBlocks MCP server also presents a Supabase-issued user session token here on the user's behalf; such a token acts as that user with the scopes their organization role allows.
Headers
Any unique string (a UUID is fine). Repeating a request with the same key and body within 24 hours replays the original response with Idempotency-Replayed: true instead of running again; the same key with a different body is a 409. Incomplete and 5xx outcomes are retained for reconciliation beyond 24 hours. Applies only on the documented endpoints. Never automatically change keys to bypass an uncertain outcome.
