decode_jwt

Pack: jwt · Endpoint: https://gateway.pipeworx.io/jwt/mcp

Decode a JSON Web Token (keyless, offline): returns the header and payload JSON plus a summary of the standard claims (iss, sub, aud, exp/iat/nbf as ISO dates, and whether it is expired). NOTE: this decodes but does NOT verify the signature — a decoded token is not a verified/trusted token.

Parameters
