Standardize text generation for your team

The `ai21_chat_completion` tool gives everyone on your team access to AI21's Jamba models. By adding this MCP Server to your repo's `.vscode/mcp.json`, every developer uses the same tools for generating text. This ensures consistency. A junior dev writing user documentation will get the same high-quality output as a senior dev. It removes guesswork and helps maintain a uniform voice across your project's written materials.

Refine documentation and UI text

Use `ai21_grammar_correction` and `ai21_text_improvements` to polish text without leaving VS Code. When you're writing a README, API documentation, or in-app instructions, you can ask Copilot's agent to find errors or suggest better phrasing. Think of it as a built-in copy editor for your whole team. It catches the small mistakes that are easy to miss when you're focused on code, helping you ship cleaner, more professional documentation.

Add AI21 to your VS Code MCP Server config

This MCP server gives your team direct, secure access to AI21's models from the editor they already use. You can use `ai21_summarize_text` on long error logs pasted into the chat or `ai21_segment_text` to understand the structure of a technical document. Because the configuration lives in your repository, onboarding a new developer is automatic. They clone the repo, and they immediately have the same capabilities as the rest of the team. It's an enterprise-ready way to add powerful text tools to your workflow.

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.

Yes. Your connection is authenticated with a Vinkius token, and all communication happens over HTTPS. The server itself runs in a secure, isolated sandbox managed by Vinkius, which is SOC 2 compliant.

You can paste the code as text into the Copilot chat window. Then ask your agent to use the `ai21_summarize_text` tool on it. It will provide a plain-language summary of the code you provided.
