shallowio.github.doteyeso-ops/mcp-server-vibes-coded · Verify this server
Check whether a paid action is protected against duplicate execution via an idempotency key. Use before retrying a payment or other side-effecting call. Do not use for content fetch — use vc_web_search / vc_page_markdown. Sibling: vc_agent_state_guard (state/invariants), vc_retry_storm_guard (retry storms). Auth: X-Vibes-Key or x402 (~$0.02). Advisory only; no local writes. Returns JSON assessing key presence/durability, or payment_required.
