`decode_jwt`

Pack: jwt · Connect: https://pipeworx.io/mcp (see Connect below for a single-pack URL)

No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/decode_jwt for the schema, then POST the same URL with its arguments for the data.

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

Name	Type	Required	Description
`token`	string	yes	A JWT (header.payload.signature).
