Show HN: MCPfinder – An MCP server that finds and installs other MCP servers

coderai — Mon, 20 Apr 2026 21:38:18 +0000

I’ve been building and using agents heavily lately. The Model Context Protocol ecosystem is growing insanely fast, but discovering and configuring new tools is still highly manual. Every time I needed to connect an agent to a new service, I had to browse registries, figure out the transport type, identify required env vars, and manually update "mcp.json" files.

So I built MCPfinder. It aggregates servers from the official MCP registry, Glama, and Smithery (around 25,000 combined entries) into a deduplicated, ranked catalog.

But the real twist is the DX: MCPfinder is itself an MCP server :D

You only install it once as your "base capability" via standard stdio: npx -y @mcpfinder/server

From then on, when you tell your AI, "I need to query my PostgreSQL database," the magic happens autonomously.

It's completely free, AGPL-3.0 licensed, and built purely to optimize AI-tool surface discovery.

I'd love to hear your thoughts, feedback, or edge cases where JSON generation for specific platforms is acting up.

Show HN: Needed instant realtime whiteboard for meetings so I built it in 1 day

coderai — Tue, 14 Apr 2026 10:30:36 +0000

Hi there. I was looking for a pastebin-like instant solution for online meetings — a shared whiteboard with real-time sync. Of course there are Excalidraw and tldraw, BUT they require signup and are overgrown with features I don't need. So I just built cnvs.app — instant sharing, no signup, real-time sync with all the essentials: drawing, writing, and pasting images. All in one day. On day two I added sticky notes, full mobile support, and Mermaid diagrams (cool thing — try pasting some Mermaid syntax there!) and deployed to Cloudflare so everyone can use it for free.

Be creative. Have fun :)

Show HN: PLAI.chat – Multi-model AI chat that doesn't store your conversations

coderai — Mon, 02 Mar 2026 14:17:39 +0000

I built PLAI.chat because I was frustrated with two things: 1) new models ship every week and I was constantly switching between apps to keep up. 2) Every service stores my conversations on their servers.

So, PLAI.chat takes a different approach: your chat history is stored only in your browser's localStorage — never on our servers. API calls go to model providers via OpenRouter, but we don't log, store, or train on any conversations — and they aren't linked to any user identity on our end. We don't store anything. The architecture makes the privacy guarantee verifiable, not just a policy claim.

You can try it right now, no account needed. Go to plai.chat and start chatting for free. For more models or higher limits, sign in with a magic link — no forced registration, no confirmation hoops.

What it does: - 300+ models (GPT, Claude, Gemini, Llama, Mistral, Qwen, and more via OpenRouter) - Free to start, pay-per-use for extended usage — no subscription - Chat history in your browser only — close the tab, it's still there; we never see it - Switch models mid-conversation to compare responses; presets for free/balanced/premium - Supports files, PDFs, images, and image generation

I also built a Slack version — but still waiting on Slack's marketplace approval, which has been... slow.

Stack: Next.js, Cloudflare Workers, Stripe, OpenRouter.

Thanks for your feedback and comments!

nice because system proofread (right click) not everywhere works

So it works locally but uses cloud AI providers I must setup and pay myself, separately?

Hi, I wanted to launch something similar, one-click OpenClaw instance ready to use, connected to some backend AI already. OpenClaw for dummies ;) Please post some update next week how did it go!

New comment by coderai in "Show HN: SunnyFlight – Find cheap weekend flights to sunny destinations"

coderai — Wed, 18 Feb 2026 12:50:07 +0000

I live in a place where unfortunately 2/3 of the year we have 0–15°C. Sometimes I look for quick weekend escapes — not to far-away countries, but somewhere closer (like Italy or Spain) where the weather might be nice for the weekend. So I combined automatic search of cheap flights with good weather.

The idea is simple: tell us your departure city, budget, and preferred temperature — we scan thousands of flights and weather forecasts every week to find you the best sunny weekend deals.

Technical stack: - Cloudflare Workers for backend (serverless, fast) - Flight data from Amadeus API + Kiwi.com - Weather from OpenWeatherMap - Email via Resend

It's completely free, no ads, no spam. Just a weekly email if we find a good match.
