Does this support AI21's Jamba models?

Yes. You can invoke the chat completion tool and instruct your agent to use specific model parameters like 'jamba-1.5-large' or 'jamba-1.5-mini' directly to leverage their native SSM-Transformer hybrid architecture.

Why use the specific summarization endpoint instead of a generic prompt?

AI21 has trained dedicated models purely for tasks like summarization and grammatical correction. Using these specialized task endpoints often yields much higher reliability, speed, and fidelity than trying to force a conversational chatbot to do the exact same task.

What languages are supported for grammar corrections?

Currently, AI21's dedicated Grammar and Paraphrase tools perform spectacularly on English, with varying outcomes for other localized languages. It is highly recommended to check their official documentation for the exact status of multi-language support boundaries.

AI21 Studio + VS Code Copilot FAQ

Common questions about integrating AI21 Studio MCP Server with VS Code Copilot.

Which VS Code version supports MCP?

MCP support requires VS Code 1.99 or later with the GitHub Copilot extension. Ensure both are updated to the latest version. Older versions of Copilot may not expose the Agent mode toggle.

How do I switch to Agent mode?

Open the Copilot Chat panel and look for two mode options: "Ask" and "Agent". Click "Agent" to enable autonomous tool calling. In Ask mode, Copilot provides conversational answers but cannot invoke MCP tools.

Can I restrict which MCP tools Copilot can access?

Yes. VS Code shows a tool consent dialog before any MCP tool is invoked for the first time. You can also configure tool access policies at the organization level through GitHub Copilot settings.

Does MCP work in VS Code Remote or Codespaces?

Yes. MCP servers configured via .vscode/mcp.json work in Remote SSH, WSL, and GitHub Codespaces environments. The MCP connection is established from the remote host, so ensure the server URL is accessible from that environment.
