How to Use the AI21 Labs MCP in Windsurf

Q: How do I configure AI21 Labs in Windsurf?

Open your /.codeium/windsurf/mcpconfig.json file and add the server endpoint. You can also use the Settings menu to navigate to the Cascade MCP Servers UI. Hit refresh in the panel to load the tools.

Q: Can Windsurf and AI21 Labs summarize my codebase?

Yes. Cascade calls ai21summarizetext on your target files. It reads the raw code or documentation and returns a condensed version right in your IDE chat.

Q: What models power the chat tools?

The ai21chatcompletion tool connects directly to Jamba models like jamba-1.5-mini. Your client routes the prompt through the MCP protocol to fetch the conversational response.

Connect AI21 Labs to Windsurf and let Cascade rewrite, summarize, and query your documents autonomously.

Rewrite and correct copy in Windsurf

The `ai21_grammar_correction` and `ai21_paraphrase_text` tools let Cascade fix your documentation directly in the editor. You highlight a messy README section and tell the agent to clean it up. Cascade reads the raw text, sends it through the API, and replaces the block with polished English. If the tone feels off, the `ai21_text_improvements` endpoint suggests stylistic tweaks without changing the core meaning.

Query large documents via MCP Server

Using `ai21_contextual_answers`, your AI client extracts exact facts from massive text blobs. Instead of pasting thousands of lines into the chat, you point Cascade at a local file and ask a question. The agent figures out the rest. It uses `ai21_segment_text` to break down long transcripts by topic, then runs the contextual query to find your answer. You get the exact paragraph you needed without scrolling through pages of noise.

Manage context files autonomously

Tools like `ai21_list_files` and `ai21_get_file` give the agent read access to your uploaded reference materials. Cascade checks what documents are already available before answering your prompt. When a reference document becomes outdated, the `ai21_delete_file` command removes it from the remote host. This keeps your workspace clean and prevents the agent from pulling stale data during chat completions.
