When integrating with platforms like Stripe, Shopify, or Banking APIs, your AI Agent often needs to sign the payload using an HMAC-SHA256 hash. LLMs cannot perform cryptographic math. If you ask an LLM to generate a SHA-256 hash of a string, it will guess and fail. This MCP solves that by offloading the cryptography to the V8 engine.

The Superpowers

  • Mathematical Certainty: Uses the native Node.js crypto library to guarantee 100% accurate hashes.
  • HMAC Signatures: Securely sign webhooks and API payloads by providing the shared secret.

hash_payload

Pass the raw payload, optionally choose the algorithm (md5, sha1, sha256, sha512), and provide a secret key if you need HMAC signing for webhook verification. Generates a mathematical cryptographic hash (MD5, SHA-256) or HMAC for signing webhooks and API payloads
