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

$3

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

$3

Get your API key from Context7

Usage

$3

`typescript
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);
`

$3

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

`typescript
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

$3

Set your API key via environment variable:

`sh
CONTEXT7_API_KEY=ctx7sk-...
`

Then use tools and agents without explicit configuration:

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