Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Real work

What teams actually run

01

Drafting Technical Reports

Upload a massive research paper, ask the agent to summarize it, and then ask it to segment the action items into a bulleted list.

02

Client Communication

Feed the agent a rough email draft, ask it to correct the grammar, and then ask it to suggest stylistic improvements to sound more authoritative.

03

Knowledge Base Creation

Upload company policy documents and use the agent to answer specific employee questions, ensuring answers are based only on the provided text.

04

Content Repurposing

Take a long-form blog post and ask the agent to paraphrase sections, then ask it to segment the content into three distinct social media posts.

Automate a task

Put AI21 Labs to work on one thing.

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.

One connector, every AI

AI21 Labs works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put AI21 Labs to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of AI21 Labs, so you can see the experience inside your AI.

It does not authenticate your account with AI21 Labs. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

Who it's for

Built for the work AI21 Labs owners hand off.

This MCP is built for professionals who spend time generating, editing, or analyzing large amounts of text. If your job involves transforming raw ideas into polished, structured content, this capability gives your agent the linguistic muscle it needs. It's designed to handle the full lifecycle of content, from initial draft to final, polished publication.

  • 01

    Writers & Editors

    Instantly improve fluency and correct grammar in raw drafts using natural language commands.

  • 02

    Researchers

    Summarize lengthy document chunks and segment specific topics without leaving your creative workspace.

  • 03

    Developers

    Integrate high-speed Jamba models and RAG capabilities into custom workflows through simple AI queries.

FAQ

Questions AI21 Labs owners ask.

  • 01

    Does this MCP only work with one type of AI client?

    No. You connect this MCP once from any MCP-compatible client, including Claude, Cursor, Windsurf, and VS Code. Vinkius manages the connection for all of them.

  • 02

    What is the difference between summarizing and extracting answers?

    Summarizing creates a condensed overview of the whole document. Extracting answers, however, uses the context to pull out specific, factual answers to questions you ask.

  • 03

    Do I need to provide an API key?

    Yes, the MCP requires authentication. You'll need to retrieve your API Key from the AI21 Studio dashboard to connect your agent.

  • 04

    Can I manage my files through the MCP?

    Yes. You can list uploaded files, get details on specific files, or delete files you no longer need in the workspace.

  • 05

    Is this good for coding tasks?

    This MCP focuses on linguistic intelligence and document processing. While it uses advanced models, its capabilities are for text manipulation, not code generation or debugging.

  • 06

    How do I find my AI21 API Key?

    Log in to the AI21 Studio Dashboard, click on your profile (top right), and navigate to API Keys to copy your token.

  • 07

    Can I use AI21 for RAG via AI?

    Yes! The contextual_answers capability allows your agent to extract precise information from provided text context using high-fidelity RAG technology.

  • 08

    Does it support grammar correction?

    Absolutely. Use the grammar_correction capability to fix spelling, syntax, and phrasing in your text programmatically.
