Context7
Feeds AI the latest docs for libraries and frameworks before it answers, so code it writes does not use outdated, removed functions.
Description from the maker (original English)
Search a curated English and Chinese web index through one read-only MCP tool.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.
Pick the AI app you use, then copy the settings.

Curated English & Chinese Search API and MCP for AI Agents & RAG Systems
*Search that can show its work. Every result carries an explicit fetched_at timestamp and provenance.*
🌐 Website • 📖 API Docs • ⚡ MCP Quickstart • 📊 Frozen Benchmarks • 📁 Examples • 🇨🇳 中文文档
Current web search APIs for AI agents suffer from three fatal flaws:
fetched_at).Annolux solves this with an agent-first curated approach:
| Feature / Metric | Annolux | Exa (Metaphor) | Tavily | Serper / Google |
|---|---|---|---|---|
| Index Quality | Curated Tech & Knowledge (EN/ZH) | Web-wide neural | Web-wide aggregator | Entire Web (noisy SEO) |
| Chinese (ZH) Tech Corpus | First-class native bilingual FTS | Moderate | Weak / Translated | Mixed with content farms |
| Explicit Snapshot Timestamp | ✅ `fetched_at` on every result | ❌ Inconsistent | ❌ Omitted | ❌ Snippet approximate only |
| Billing Guarantee | ✅ 1 credit only on 2xx success | Request-based | Request-based | Request-based |
| Failed / Timeout Queries | 🆓 0 Credits charged | ❌ Billed | ❌ Billed | ❌ Billed |
| MCP Tool Surface | Single lean `search_web` (Minimal token waste) | Multiple bulky tools | Multi-step tools | Needs custom bridge |
| Domain Restriction | ✅ Exact hostname filtering (`domains`) | ✅ Supported | ✅ Supported | Limited site: query |
| Free Starter Tier | 1,000 credits / month | Limited trial | 1,000 / mo | 2,500 one-time |
Node.js 18+ is the only prerequisite. Start in the zero-config sandbox—no account or API key is required:
npx -y annolux-mcp
For the full monthly allowance, create a free key at annolux.com and pass it through the process environment:
ANNOLUX_API_KEY=ann_live_YOUR_API_KEY npx -y annolux-mcp
Annolux implements the official Model Context Protocol (MCP) specification with a single, high-efficiency tool: search_web.
npx -y @smithery/cli install annolux-mcp --client claude
npx -y @smithery/cli install annolux-mcp --client cursor
- **Glama Online Playground**: Test queries instantly without local setup on [Glama.ai](https://glama.ai/mcp/servers/eason4kim-rocket/annolux).
claude mcp add annolux -- npx -y annolux-mcp
This starts in sandbox mode. To use an account key, add it with -e ANNOLUX_API_KEY=ann_live_YOUR_API_KEY before --.
Add to your project .cursor/mcp.json or global configuration:
