Upstash Context7 AI SDK

@upstash/context7-tools-ai-sdk provides Vercel AI SDK compatible tools and agents that give your AI applications access to up to date library documentation through Context7.

Use this package to:

• Add documentation lookup tools to your AI SDK workflows with generateText or streamText
• Create documentation aware agents using the pre-configured Context7Agent
• Build RAG pipelines that retrieve accurate, version specific code examples

The package provides two main tools:

• resolveLibrary - Searches Context7's database to find the correct library ID
• getLibraryDocs - Fetches documentation for a specific library with optional topic filtering

Quick Start

Install

npm install @upstash/context7-tools-ai-sdk @upstash/context7-sdk ai zod

Get API Key

Get your API key from Context7

Usage

Using Tools with generateText

import { resolveLibrary, getLibraryDocs } from "@upstash/context7-tools-ai-sdk";
import { generateText, stepCountIs } from "ai";
import { openai } from "@ai-sdk/openai";

const { text } = await generateText({
  model: openai("gpt-4o"),
  prompt: "How do I use React Server Components?",
  tools: {
    resolveLibrary: resolveLibrary(),
    getLibraryDocs: getLibraryDocs(),
  },
  stopWhen: stepCountIs(5),
});

console.log(text);

Using the Context7 Agent

The package provides a pre-configured agent that handles the multi-step workflow automatically:

import { Context7Agent } from "@upstash/context7-tools-ai-sdk";
import { anthropic } from "@ai-sdk/anthropic";

const agent = new Context7Agent({
  model: anthropic("claude-sonnet-4-20250514"),
});

const { text } = await agent.generate({
  prompt: "How do I set up routing in Next.js?",
});

console.log(text);

Configuration

Environment Variables

Set your API key via environment variable:

CONTEXT7_API_KEY=ctx7sk-...

Then use tools and agents without explicit configuration:

const tool = resolveLibrary(); // Uses CONTEXT7_API_KEY automatically
