What is the JWT Decoder & Verifier MCP Server?
While an AI Agent can base64-decode a JSON Web Token to read its claims, it is physically incapable of verifying the cryptographic signature. This means an AI could accept a forged token or an expired session without knowing. This MCP solves that by offloading the mathematical signature verification to the V8 engine.
The Superpowers
- Cryptographic Verification: Uses
jsonwebtokento strictly verify the token signature against the provided secret key. - Local Decoding: Extract user IDs, roles, and expiration dates instantly without network latency.
Built-in capabilities (1)
Pass the JWT string and optionally a secret or public key. The engine decodes the header, payload, and validates the signature offline. Decodes JSON Web Tokens (JWT) and mathematically verifies cryptographic signatures offline

Frequently asked questions
Can I decode a token without the secret?
Yes, if you omit the secret, it will only decode the payload, but it will not verify authenticity.
Does it check expiration dates?
Yes, if the secret is provided, it will automatically throw an error if the token is expired.
What algorithms does it support?
It supports standard JWT algorithms including HS256, HS384, and HS512.
How does Cline connect to MCP servers?
Cline reads MCP server configurations from its settings panel in VS Code. Add the server URL and Cline discovers all available tools on initialization.
Can Cline run MCP tools without approval?
By default, Cline asks for confirmation before executing tool calls. You can configure auto-approval rules for trusted servers in the settings.
Does Cline support multiple MCP servers at once?
Yes. Configure as many servers as needed. Cline can use tools from different servers within the same autonomous task execution.
