Context7 Platform - Up-to-date Code Docs For Any Prompt
(opens in a new tab)
-purple){kind=icon}
❌ Without Context7
LLMs rely on outdated or generic information about the libraries you use. You get:
- ❌ Code examples are outdated and based on year-old training data
- ❌ Hallucinated APIs that don’t even exist
- ❌ Generic answers for old package versions
✅ With Context7
Context7 pulls up-to-date, version-specific documentation and code examples straight from the source — and places them directly into your prompt.
Create a Next.js middleware that checks for a valid JWT in cookies
and redirects unauthenticated users to `/login`. use context7Configure a Cloudflare Worker script to cache
JSON API responses for five minutes. use context7Show me the Supabase auth API for email/password sign-up.Context7 fetches up-to-date code examples and documentation right into your LLM’s context. No tab-switching, no hallucinated APIs that don’t exist, no outdated code generation.
Works in two modes:
- CLI + Skills — installs a skill that guides your agent to fetch docs using
ctx7CLI commands (no MCP required) - MCP — registers a Context7 MCP server so your agent can call documentation tools natively
Installation
[!NOTE] API Key Recommended: Get a free API key at context7.com/dashboard (opens in a new tab) for higher rate limits.
Set up Context7 for your coding agents with a single command. The ctx7 CLI requires Node.js 18 or newer.
npx ctx7 setupAuthenticates via OAuth, generates an API key, and installs the appropriate skill. You can choose between CLI + Skills or MCP mode. Use --cursor, --claude, or --opencode to target a specific agent.
To remove the generated setup later, run npx ctx7 remove. If you globally installed the CLI with npm install -g ctx7, remove that package separately with npm uninstall -g ctx7.
To configure manually, use the Context7 server URL https://mcp.context7.com/mcp with your MCP client and pass your API key via the Authorization: Bearer YOUR_API_KEY header. See the link below for client-specific setup instructions.

Important Tips
Use Library Id
If you already know exactly which library you want to use, add its Context7 ID to your prompt. That way, Context7 can skip the library-matching step and directly retrieve docs.
Implement basic authentication with Supabase. use library /supabase/supabase for API and docs.The slash syntax tells Context7 exactly which library to load docs for.
Specify a Version
To get documentation for a specific library version, just mention the version in your prompt:
How do I set up Next.js 14 middleware? use context7Context7 will automatically match the appropriate version.
Add a Rule
If you installed via ctx7 setup, a skill is configured automatically that triggers Context7 for library-related questions. To set up a rule manually instead, add one to your coding agent:
- Cursor:
Cursor Settings > Rules - Claude Code:
CLAUDE.md - Or the equivalent in your coding agent
Example rule:
Always use Context7 when I need library/API documentation, code generation, setup or configuration steps without me having to explicitly ask.Available Tools
CLI Commands
ctx7 library <name> <query>: Searches the Context7 index by library name and returns matching libraries with their IDs.ctx7 docs <libraryId> <query>: Retrieves documentation for a library using a Context7-compatible library ID (e.g.,/mongodb/docs,/vercel/next.js).
MCP Tools
resolve-library-id: Resolves a general library name into a Context7-compatible library ID.query(required): The user’s question or task (used to rank results by relevance)libraryName(required): The name of the library to search for
query-docs: Retrieves documentation for a library using a Context7-compatible library ID.libraryId(required): Exact Context7-compatible library ID (e.g.,/mongodb/docs,/vercel/next.js)query(required): The question or task to get relevant documentation for

⭐ Star History
📄 License
MIT
Colophon
How this issue was made- Source
- github.com/upstash/context7, branch
master, last pushed 9 August 2026. - Licence
- MIT — the text of every chapter is reproduced unmodified, frontmatter included, under the upstream licence.
- Discovery
- 5 chapters found by walking the repository tree for
SKILL.md, not by matching a directory convention. 3 distinct layouts observed:packages/pi/skills/*/SKILL.md,plugins/agent-plugins/context7/skills/*/SKILL.md,skills/*/SKILL.md. - Duplicates collapsed
- 4 mirror copies folded into their canonical chapter — republished for Alternate. Copies match on content hash and on position once a leading per-agent prefix is stripped, because the same skill is routinely shipped under a dozen agent directories with a dozen different hashes.
- Issue colours
- Resolved from a curated brand profile — hue 163°, chroma 0.179. Two accent tones are generated per issue and each is proven against its own ground before it ships: a single accent that passes AA on both light and dark paper is arithmetically impossible.
- Heading repairs
- 1 repair applied to the front matter so the document has one
h1and no skipped levels:- Shifted “18 headings” from h1 to h2 so the chapter title is the only h1.
- Spec compliance
- Every chapter satisfies the Agent Skills specification’s frontmatter rules.
- Images
- Images inside a chapter come from the upstream repository. Where the author gave no alternative text we mark the image decorative rather than inventing a description — a plausible caption we made up is worse than none for the reader who depends on it.
- Marketplace
- A plugin manifest is published at
.claude-plugin/marketplace.jsonby Upstash, declaring 1 plugin. It is read for editorial metadata only — never as the skill index, which is always the repository tree. - Signal
- Install counts come from skills.sh. They measure downloads, not quality, and an unranked repository is not an unread one.
- Agent surfaces
- The whole issue is available as one markdown document at
/upstash/context7.md, and each chapter at its own.mdURL. - Publication
- Set by Skills Docs from the source repository. Body text is Literata at the reader’s chosen size and measure; code is Geist Mono. Nothing on this page was written by us except this paragraph.
