Bring Ai21
to Vercel AI SDK
Learn how to connect AI21 Labs to Vercel AI SDK and start using 10 AI agent tools in minutes. Fully managed, enterprise secure, and ready to use without writing a single line of code.
What is the AI21 Labs MCP Server?
Connect your AI agent to the AI21 Studio API and take full control of state-of-the-art Natural Language Processing (NLP) workflows through natural conversation.
What you can do
- Chat Orchestration — Leverage the blazing-fast Jamba models (e.g.,
jamba-1.5-mini) to generate high-fidelity conversational responses and structured text programmatically - Task-Specific NLP Intelligence — Access pre-trained specific endpoints to summarize long texts, correct grammar, paraphrase styles, and segment topics without complex prompting
- Document Intelligence & RAG — Programmatically manage your AI21 workspace library and extract high-fidelity contextual answers based strictly on provided documents
- Stylistic Optimization — Use specialized tools for text improvements and paraphrasing to coordinate your brand's digital voice across multiple languages
- Infrastructure Monitoring — Manage uploaded files and verify account-level API connectivity directly through your agent for instant performance reporting
How it works
1. Subscribe to this server
2. Retrieve your API Key from the AI21 Studio dashboard
3. Start orchestrating your language intelligence from Claude, Cursor, or any MCP client
No more manual toggling between writing tools or guessing complex prompt instructions. Your AI acts as your dedicated linguistic engineer and document architect.
Who is this for?
- Writers & Editors — instantly improve fluency and correct grammar of raw drafts using natural language commands
- Researchers — summarize lengthy document chunks and segment specific topics without leaving your creative workspace
- Developers — integrate high-speed Jamba models and RAG capabilities into custom workflows through simple AI queries

Frequently asked questions
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.
Can I use AI21 for RAG via AI?
Yes! The contextual_answers tool allows your agent to extract precise information from provided text context using high-fidelity RAG technology.
Does it support grammar correction?
Absolutely. Use the grammar_correction tool to fix spelling, syntax, and phrasing in your text programmatically.
How does the Vercel AI SDK connect to MCP servers?
Import createMCPClient from @ai-sdk/mcp and pass the server URL. The SDK discovers all tools and provides typed TypeScript interfaces for each one.
Can I use MCP tools in Edge Functions?
Yes. The AI SDK is fully edge-compatible. MCP connections work on Vercel Edge Functions, Cloudflare Workers, and similar runtimes.
Does it support streaming tool results?
Yes. The SDK provides streaming primitives like useChat and streamText that handle tool calls and display results progressively in the UI.
