Windsurf MCP Server for Jamba Models

The `chat_completion` tool connects Cascade directly to AI21's Jamba-1.5 models for deep context reasoning. You hand Windsurf a massive log file or documentation directory, and the agent feeds it into the Jamba context window without you having to manually copy-paste segments. If the output needs refining, Cascade chains the response into the `text_completion` tool to format the specific code blocks or text structures you requested. You set the goal once, and this MCP Server handles the multi-step prompt routing behind the scenes.

Chain Rewrites and Grammar Fixes

Through this MCP connection, the `paraphrase` tool lets Windsurf rewrite your draft documentation across five different styles, from casual to formal. Cascade reads your rough notes, runs the paraphrase operation, and injects the polished text right back into your markdown files. Before finalizing the commit, the agent automatically triggers `grammar_corrections` to catch awkward phrasing or typos. You get clean, professional docs generated and reviewed in a single autonomous pass.

Autonomous Text Summarization

The `summarize` tool condenses long-form text based strictly on API limits, letting Cascade digest massive files quickly. When you ask Windsurf to explain a complex legacy codebase, it pulls the relevant files and shrinks the core logic down to a readable size. For finer control, Cascade might use the `segmentation` tool to break those long files down into individual sentences first. Then it runs `embed_texts` to generate vector representations, giving your workspace a fast, searchable index of the project.

Setup guide

Set up AI21 Studio MCP in Windsurf

Prerequisites

Windsurf IDE installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP configuration

Click the Cascade assistant icon in the sidebar, then click the hammer icon (🔨) at the top of the panel. Select "Configure" to open ~/.codeium/windsurf/mcp_config.json.
2

Add the AI21 Studio MCP

Paste the JSON snippet shown on the right into the mcpServers object. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Refresh MCPs

Go back to the hammer icon (🔨) in Cascade and click "Refresh". Windsurf will detect the new server. No full restart is needed — the connection is hot-reloaded.
4

Verify in Cascade

Start a new Cascade conversation and ask something like "Show my AI21 Studio payment history." If connected, Cascade will call the AI21 Studio tools directly. You will see a green dot next to the server name in the MCP panel.

Common questions about AI21 Studio MCP in Windsurf

Open your ~/.codeium/windsurf/mcp_config.json file and add the server details under the mcpServers block. You can also use the Settings menu to navigate to the Cascade MCP Servers UI and click refresh.

Yes, the paraphrase tool handles text styling perfectly. Cascade reads your existing comments and rewrites them to be shorter or more formal depending on your exact instructions.

The server exposes Jamba-1.5-large and Jamba-1.5-mini through the chat completion endpoint. Cascade routes your prompts to these models when you need massive context windows processed.

You get access to specialized grammatical error correction and text segmentation tools. Instead of relying on general prompting, Cascade calls dedicated endpoints built specifically for text manipulation.

Your raw text files, documentation drafts, and codebase comments pass through the MCP Server to AI21's API endpoints. Vinkius isolates this connection in a V8 sandbox using an ephemeral token, ensuring the connection drops the second Cascade finishes the task.
