Use the ctx7 CLI to fetch library documentation, manage AI coding skills, and configure Context7 MCP. Activate when the user mentions "ctx7" or "context7", needs current docs for any library, wants to install/search/generate skills, or needs to set up Context7 for their AI coding agent.
The Context7 CLI does three things: fetches up-to-date library documentation, manages AI coding skills, and sets up Context7 MCP for your editor.
Make sure the CLI is up to date before running commands:
npm install -g ctx7@latest
Or run directly without installing:
npx ctx7@latest <command>
What this skill covers
Documentation — Fetch current docs for any library. Use when writing code, verifying API signatures, or when training data may be outdated.
Skills management — Install, search, suggest, list, remove, and generate AI coding skills.
Setup — Configure Context7 MCP for Claude Code / Cursor / OpenCode.
Quick Reference
# Documentation
ctx7 library <name> <query> # Step 1: resolve library ID
ctx7 docs <libraryId> <query> # Step 2: fetch docs
# Skills
ctx7 skills install /owner/repo # Install from a repo (interactive)
ctx7 skills install /owner/repo name # Install a specific skill
ctx7 skills search <keywords> # Search the registry
ctx7 skills suggest # Auto-suggest based on project deps
ctx7 skills list # List installed skills
ctx7 skills remove <name> # Uninstall a skill
ctx7 skills generate # Generate a custom skill with AI (requires login)
# Setup
ctx7 setup # Configure Context7 MCP (interactive)
ctx7 login # Log in for higher rate limits + skill generation
ctx7 whoami # Check current login status
Authentication
ctx7 login # Opens browser for OAuth
ctx7 login --no-browser # Prints URL instead of opening browser
ctx7 logout # Clear stored tokens
ctx7 whoami # Show current login status (name + email)
Most commands work without login. Exceptions: skills generate always requires it; ctx7 setup requires it unless --api-key or --oauth is passed. Login also unlocks higher rate limits on docs commands.
Set an API key via environment variable to skip interactive login entirely:
export CONTEXT7_API_KEY=your_key
Common Mistakes
Library IDs require a / prefix — /facebook/react not facebook/react
Always run ctx7 library first — ctx7 docs react "hooks" will fail without a valid ID
Repository format for skills is /owner/repo — e.g., ctx7 skills install /anthropics/skills
skills generate requires login — run ctx7 login first
upstash-redis-jsupstashWork with the @upstash/redis TypeScript/JavaScript SDK, a serverless HTTP-based Redis client for Next.js, Vercel, Cloudflare Workers, edge runtimes, and Node.js. Use when adding a cache (cache-aside, write-through, TTL and expiration strategies), session storage and user sessions, a key-value store, leaderboards and rankings with sorted sets, counters, distributed locks, queues with lists, streams and consumer groups, sparse index-addressed arrays and ring buffers (ARSET, ARINSERT, ARRING, ARGREP, AROP), embeddings and nearest-neighbour vector search stored inside Redis (VECTOR commands via redis.vector, separate from @upstash/vector), JSON documents, pipelines and MULTI/EXEC transactions, Lua scripting, read replicas, or full-text search, typo-tolerant search, facets, aggregations, and search over Redis stream entries with Upstash Redis Search (different from regular FT.SEARCH; also available for TCP clients via @upstash/search-redis and @upstash/search-ioredis). Also use when migrating from ioredis or node-16.8 k16.8 k instalaciones en skills.sh0
upstash-ratelimit-jsupstashRate limiting for serverless and edge apps with the @upstash/ratelimit TypeScript/JavaScript SDK backed by Upstash Redis. Use when adding a rate limiter or throttling to an API route, Next.js middleware, Vercel Edge, Cloudflare Workers, or any HTTP endpoint; returning 429 Too Many Requests; choosing between fixed window, sliding window, and token bucket algorithms; limiting per user, IP, API key, or tenant with prefixes and custom keys; protecting login, signup, form, or AI endpoints from abuse, bots, and brute force; using deny lists, ephemeral caching, analytics, timeouts, and multi-region rate limits; or estimating the Redis command cost of rate limiting. Also use when the user says rate limit, rate-limiting, throttle, quota, request limits, or traffic protection.16.4 k16.4 k instalaciones en skills.sh0
find-docsupstashRetrieves up-to-date documentation, API references, and code examples for any developer technology. Use this skill whenever the user asks about a specific library, framework, SDK, CLI tool, or cloud service — even for well-known ones like React, Next.js, Prisma, Express, Tailwind, Django, or Spring Boot. Your training data may not reflect recent API changes or version updates.8,0008,000 instalaciones en skills.sh0
context7-mcpupstashThis skill should be used when the user asks about libraries, frameworks, API references, or needs code examples. Activates for setup questions, code generation involving libraries, or mentions of specific frameworks like React, Vue, Next.js, Prisma, Supabase, etc.5,4005,400 instalaciones en skills.sh0
upstashupstashWork with any Upstash product, SDK, or tool, including serverless Redis (caching, sessions, leaderboards, key-value storage), Ratelimit (rate limiting and throttling), QStash (message queue, cron schedules, background jobs), Workflow (durable long-running functions), Vector (vector database for embeddings, semantic search, and RAG), Search (full-text and semantic search), Box (sandboxed cloud containers for AI agents, TypeScript/JavaScript and Python), Blob (serverless S3-compatible file storage with direct browser uploads), the Upstash CLI, and no-signup scratch Redis for agents. Use when the user mentions Upstash or needs any of these capabilities in a serverless, edge, or Node.js app.3,0003,000 instalaciones en skills.sh0
