Context7 MCP

# Upstash Context7 AI SDK `@upstash/context7-tools-ai-sdk` provides [Vercel AI SDK](https://ai-sdk.dev/) 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 ```bash npm install @upstash/context7-tools-ai-sdk @upstash/context7-sdk ai zod ``` ### Get API Key Get your API key from [Context7](https://context7.com) ## Usage ### Using Tools with `generateText` ```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); ``` ### Using the Context7 Agent 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 ### Environment Variables 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 ``` ## Docs See the [documentation](https://context7.com/docs/agentic-tools/ai-sdk/getting-started) for details. ## Contributing ### Running tests ```sh pnpm test ``` ### Building ```sh pnpm build ```
