How this service works
The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.
Output
Returns expiration status of the submitted JWT token, including whether it is currently valid or expired, the expiration timestamp extracted from the token claims, and likely the remaining time until expiry or how long ago it expired.
Example use cases
Check auth token before API call
“Before I make this API request, can you verify whether this JWT is still valid and hasn't expired yet: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE3MDA0MDAwMDB9.abc123”
Debug expired session token
“My user is getting logged out unexpectedly — can you check this JWT token and tell me if it's expired and when exactly it expired: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiJ1c2VyMTIzIiwiZXhwIjoxNjk5OTk5OTk5fQ.xyz”
Proactive token refresh monitoring
“I have this JWT token used by our service — can you tell me how much time is left before it expires so I know if I need to refresh it soon: eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE3MDUwMDAwMDB9.def456”
Technical details
Endpoint
POSThttps://api.m2mcent.com/jwt-token-expiration-mcp/api/processWhen to prefer
Choose this endpoint when you need a quick, reliable check of JWT token expiration status without maintaining a local JWT parsing library. It is especially useful in agentic workflows where tokens are passed between services and expiry must be verified before proceeding, or when debugging authentication issues in systems where token lifetimes are unclear.
Side effects
- Malformed or non-JWT string input returns an error or invalid response
- Token without an exp claim may return ambiguous or null expiration data
- Network timeout or service unavailability returns a 5xx error
- Invalid JSON in the data field causes a parsing error
- Empty or missing data field returns a validation error
