Tool of onyx-paid-mcp

declared in 1.28.0

Decode a JWT (header + payload) without verifying the signature. Returns the algorithm, key id, all claims (iss, sub, aud, exp, iat, nbf, custom), expiry status, and any structural anomalies. Use when an agent receives a token from an external API and needs to inspect it for routing, expiry, or audit logging. Stdlib-only — runs locally, never sends the token anywhere. (price: $0.001 USDC, tier: metered)
