Connecting JWT Decoder to the Vercel AI SDK

About a minute, in your code

  1. 1Install the MCP client: npm install @ai-sdk/mcp, and import createMCPClient from '@ai-sdk/mcp'.
  2. 2Create the client with your JWT Decoder link as the transport: { type: 'http', url: '<your link>' }. The link above is the URL.
  3. 3Call client.tools() and pass the tools to streamText. JWT Decoder is now part of your AI SDK app.

Vercel AI SDK + JWT Decoder

One chat. Your JWT Decoder, live inside Vercel AI SDK.

Real prompts, answered with live data. This is the kind of interaction your app will have once the client is in.

Waiting for input…

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

These prompts ship with the JWT Decoder Connector. Once yours is connected, they work in your sessions.

The full capability set, the prompts and the observed latency live on the JWT Decoder Connector page.

Mission Control

See everything your Vercel AI SDK agents do in JWT Decoder.

When your app runs a tool in JWT Decoder, it happens inside your code: you see the output, but not the request itself, what data it carried, or whether a rule was broken.

Now every move lands on your screen.

Every execution is recorded, enforced, and shown to you: what ran, what it returned, what was blocked, and why.

Request Volume & Latency

requests latency

Every request your Vercel AI SDK agents make through JWT Decoder is logged, enforced and auditable. See how AI Governance turns agent activity into accountability, and what it means for your JWT Decoder workflows.

What sets us apart

It's not just the Connector that stays safe. Everything your agents do through it is.

Connecting JWT Decoder to your AI is step one. But an open line between your agents and JWT Decoder is only half the story: without protection, every action they take runs unguarded.

That's why protection doesn't stop at the door.

Every action your agents take through the Connector runs inside our infrastructure: signed activity logs, automatic key rotation, spending limits that pause instead of surprise, and a sandbox that isolates every execution.

01

Tamper Proof Activity Log

Every request your agents make in JWT Decoder is recorded and signed, so any change to the history becomes detectable.

02

Automatic Key Rotation

We rotate security keys every 24 hours. Your JWT Decoder connection stays protected without any manual work.

03

Spending Protection

We enforce the spending limit you choose and pause actions that exceed it until approval is received. Your JWT Decoder actions never surprise you.

04

Isolated Sandbox

Every execution through JWT Decoder runs isolated, with 34+ security rules covering memory, CPU, network access, file handling and execution.

05

Security Event Streaming

Security events flow to Splunk, Datadog or your own webhook, so JWT Decoder activity lands in the tools you already rely on.

06

Instant Resume

Idle connections resume in 3 to 5 ms while preserving their state, keeping your Vercel AI SDK sessions responsive.

07

Malicious File Protection

We detect compressed files designed to exhaust system resources and block them before they ever reach JWT Decoder.

08

Credential Validation

We test your JWT Decoder credentials before saving them. Invalid credentials are rejected instead of being stored.

09

Separate Usage Limits

Usage stays isolated per account, so activity in one connection never consumes another account's allowance.

One Connector, one link, and the whole operation is protected. Not just the connection: everything your agents do through it.

These guarantees are not add-ons: they are the infrastructure every JWT Decoder connection runs on. Read how our infrastructure protects everything your Vercel AI SDK agents do, end to end.

  2. You add the link in your code

    Vinkius gives you one connection link. In your app, you create an MCP client with the link as the HTTP transport URL, and the tools are ready.

FAQ

Vercel AI SDK access questions.

  • 01

    Which package does this use?

    @ai-sdk/mcp, with the createMCPClient function. HTTP and SSE transports are supported, with optional headers and OAuth via an authProvider.

  • 02

    If I connect JWT Decoder to my app, can I use the same connection in Claude or ChatGPT later?

    Yes, and that's the point: the connection is yours, not the app's. You paste the same link in any AI you use, and there's nothing new to set up or pay again. Connect a new AI and JWT Decoder is already there.

  • 03

    Do I need to hand my JWT Decoder password to my app?

    Never. You sign in once at Vinkius, and we keep your logins encrypted and away from your AI. Your code only ever sees the link, and you can remove it whenever you want.

  • 04

    What can my app actually do with JWT Decoder?

    Whatever the Connector covers: check data, run actions and bring answers back. Pass the tools to streamText and the model picks the right one. The Connector page lists every capability, with real examples you can copy.

  • 05

    The tools don't show up. What do I check?

    Confirm the url matches your link exactly and that the Connector is active in your Vinkius account, then call tools() again. A deactivated Connector stops responding.

  • 06

    Can I remove the access later?

    Anytime. Close the client and remove the tools from your call, and JWT Decoder leaves your app. Your Vinkius account keeps the connection and its history either way, ready for the next AI.

About the Connector

What JWT Decoder adds to your AI.

Once you connect it, your AI gains 2 capabilities: the exact actions it can take in JWT Decoder when you ask. The Connector page lists every one of them in detail, alongside the latency we measure in production and prompts worth trying first.
