What is the JWT & Base64 Decoder MCP Server?
Decode Base64 strings and JWT tokens with exact binary precision using native Node buffers. Never let an LLM guess an expiration date again.
Built-in capabilities (2)
Pass the raw JWT string and receive the parsed JSON without any signature verification. Decodes any Base64 string deterministically into UTF-8 text
Pass the raw Base64 text and receive the decoded content. Decodes a JWT token deterministically. Extracts the header, payload, and calculates the exact expiration date
Why Vercel AI SDK?
The Vercel AI SDK gives every JWT & Base64 Decoder tool full TypeScript type inference, IDE autocomplete, and compile-time error checking. Connect 2 tools through Vinkius and stream results progressively to React, Svelte, or Vue components. works on Edge Functions, Cloudflare Workers, and any Node.js runtime.
- —
TypeScript-first: every MCP tool gets full type inference, IDE autocomplete, and compile-time error checking out of the box
- —
Framework-agnostic core works with Next.js, Nuxt, SvelteKit, or any Node.js runtime. same JWT & Base64 Decoder integration everywhere
- —
Built-in streaming UI primitives let you display JWT & Base64 Decoder tool results progressively in React, Svelte, or Vue components
- —
Edge-compatible: the AI SDK runs on Vercel Edge Functions, Cloudflare Workers, and other edge runtimes for minimal latency

Frequently asked questions
Is it secure?
Yes, decoding runs completely local.
Does it verify the JWT signature?
No, this is a strict decoder for reading payloads, not an authentication gateway.
Can it decode hex as well?
It is specialized in Base64 and JWT headers/payloads.
How does the Vercel AI SDK connect to MCP servers?
Import createMCPClient from @ai-sdk/mcp and pass the server URL. The SDK discovers all tools and provides typed TypeScript interfaces for each one.
Can I use MCP tools in Edge Functions?
Yes. The AI SDK is fully edge-compatible. MCP connections work on Vercel Edge Functions, Cloudflare Workers, and similar runtimes.
Does it support streaming tool results?
Yes. The SDK provides streaming primitives like useChat and streamText that handle tool calls and display results progressively in the UI.
createMCPClient is not a function
Install: npm install @ai-sdk/mcp
