Build faster.
Ship better.
Give your AI coding assistant real-world context. Web browsing, deep research, and secure tunneling—plug-and-play MCP servers for your IDE.
MCP Tools
Products Live
API Calls (Free Tier)
Small, focused tools that do one job well. Each stands alone — and is even better together. No bloat. No dark patterns.
The tools
Everything you need to supercharge your AI coding assistant
lum-browser
Real web access for your AI. Search, follow links, extract and analyze content — get current, sourced answers instead of guesses.
lum-deep-search
Multi‑source research, synthesized. It searches, compares, and cites — so your AI recommends with evidence, not vibes.
lrok
Share localhost in seconds. Clean, readable subdomains, HTTPS by default, and platform tracking. Like ngrok — with nicer links.
How it works
Three steps to supercharge your AI coding assistant
Sign up & get your API key
Login with Google or GitHub (Firebase auth). Create an API key in 30 seconds. No credit card needed.
const apiKey = "lum_live_a1b2c3d4e5f6..."
Configure your AI assistant
Add lum.tools MCP servers to Cursor, Cline, or any MCP-compatible tool. Takes 2 minutes.

"mcpServers": {
"lum-browser": {
"url": "https://lum-browser.lum.tools/mcp",
"headers": { "Authorization": "Bearer " }
}
}
}
Watch your AI get smarter
Your AI can now search Stack Overflow, browse docs, research technologies, and fact-check claims with real web access.
await browse("https://docs.python.org/3/library/asyncio.html")
await search("FastAPI async best practices")
await research("kubernetes horizontal pod autoscaling")
Why developers use this
Real scenarios where lum.tools actually saves you time
Stop copy-pasting docs
"Check the latest React docs for useEffect patterns" → AI browses the actual docs, not 2-year-old training data. No more tab switching.
Actual solutions, not hallucinations
Your AI searches Stack Overflow and GitHub issues for real solutions. Stop debugging AI's made-up fixes.
Compare technologies properly
"Postgres vs MySQL for my use case" → AI researches multiple sources and synthesizes a real answer. Not just vibes.
Share demos instantly
lrok your dev server → share "happy-turtle.t.lum.tools" with your team. No more "works on my machine" screenshots.
About pricing
100% free right now while we figure out fair pricing. No credit card. No gotchas.
Free tier forever
Generous limits for real work. Not a 14-day trial or toy tier.
Pay for usage, not hostages
When we add billing, you'll pay for what you use. Not for basic features we arbitrarily locked.
Open source where possible
lrok is MIT. Don't like our hosting? Self-host it. We're cool with that.
