Team-wide token debugging in VS Code

Commit your MCP config to your repo to ensure everyone on your team has the same debugging tools. The `inspect_jwt` tool is now part of your project's shared infrastructure. This eliminates the 'it works on my machine' problem for auth debugging. Everyone sees the same decoded headers and payloads.

Automate token checks in VS Code

Use Copilot Chat to inspect tokens during code reviews. The `inspect_jwt` tool provides instant visibility into the claims structure without leaving the IDE. It makes security diagnostics a standard part of your PR process. You can quickly confirm if your tokens contain the expected scopes or roles.

Secure token analysis in VS Code

Your team's tokens stay inside your development environment. The `inspect_jwt` tool operates entirely offline, keeping your auth secrets away from public debugging sites. It is built for enterprise requirements. You maintain full control over your data while gaining deep insight into your token structures.

Setup guide

Set up Deterministic JWT Inspector MCP in VS Code Copilot

Prerequisites

VS Code 1.99 or later with GitHub Copilot extension
Active Vinkius subscription with a valid endpoint token

1

Open MCP configuration

Open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and run "MCP: Add Server". Select HTTP (Streamable) as the server type. VS Code will create .vscode/mcp.json in your workspace.
2

Add the Deterministic JWT Inspector MCP

Paste the JSON snippet shown on the right into your .vscode/mcp.json. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Switch to Agent mode

Open Copilot Chat (Cmd+Shift+I / Ctrl+Shift+I) and switch to Agent mode using the dropdown. MCP tools are only available in Agent mode — they do not appear in Edit or Ask modes.
4

Verify the connection

In the Copilot Chat input, type # to list available tools. You should see the Deterministic JWT Inspector tools listed. Try asking: "List my recent Deterministic JWT Inspector transactions" and Copilot will invoke them automatically.

Common questions about Deterministic JWT Inspector MCP in VS Code Copilot

Create a .vscode/mcp.json file in your root directory. Add the server configuration there, and your entire team will have access to the tool via Copilot Chat.

No. It is a utility for inspecting the content of a JWT. It explicitly does not verify signatures and should not be used for security-critical authentication decisions.

The server parses tokens locally using your machine's resources. Your sensitive payload data is never stored or transmitted to the vendor.

It extracts the header, the full payload claims, and the expiration timestamp. It provides these as a structured object for easy reading in your chat window.

Yes. Because the config is checked into Git, your team can audit the tool definition and ensure it meets your internal security and development policies.
