Products that do what Largest Open Source MCP Repo (280) does
Ash here, founder of Activepieces (open source automation). 2 years ago, we launched Activepieces as the open source Zapier (https://news.ycombinator.com/item?id=34723989). Ever since, we grew total integrations (pieces) to 280 of which 60% were built by our community! Now with the growing popularity of MCP, we built tools around these to turn them into MCP servers. So now every open source integration on Activepieces is an MCP, and we like to think it’s the largest open source MCP repo so far (MIT licensed). With these tools, you can: - Self host the MCP server or use our…

I’ve been building Canine for about 2 years now, and have slowly grown it to about ~1000 developers using it for deploying all sorts of apps / projects / etc. Amazingly, the whole thing is still able to run on a single 48GB Hetzner VPS. Think of it basically like Coolify, for Kubernetes. I previously posted about it here: https://news.ycombinator.com/item?id=44292103 Recently, we added MCP capabilities to canine, and I was shocked how well it worked. It basically is able to create services, cron jobs, databases, get the logs for these and redeploy. See it here:…

Hey HN! I’m Gui from deco (decocms.com). We’ve been using this tool internally as the foundation for a few customer AI platforms, and today we’re open-sourcing it as MCP Mesh. MCP is quickly becoming the standard for agentic systems, but… once you go past a couple servers it turns into the same problems for every team: - M×N config sprawl (every client wired to every server, each with its own JSON + ports + retries) - Token + tool bloat (dumping tool definitions into every prompt doesn’t scale) - Credentials + blast radius (tokens scattered across clients, hard to audit, hard to revoke) - No…

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…

Hi HN, I'm Gzuuus, the creator of ContextVM this is my first post here, hope you find it interesting! I started building ContextVM some months ago, this is an open protocol that runs the Model Context Protocol (MCP) over Nostr. In practice, it’s a transport for MCP that lets you expose remote servers without needing a domain, inbound ports, or OAuth, clients, and servers only need an outbound internet connection. The problem I ran into: When deploying a remote MCP server you can feel the pain. You usually need a domain name, a static IP, TLS certificates, port forwarding, and some way to…

Everyone and their gran have been saying that MCP is dead. But could it be that MCP's saving grace has been with us all along - hiding in plain sight? A feature buried in Claude Code's Jan 2026 release may have marked the most powerful development in MCP since its inception - and almost nobody noticed. Dynamic Tool Registration. Dynamic tool registration extends an MCP server's abilities beyond that of just a glorified swagger doc - allowing the server not just to list a static set of tools, but to dynamically add and remove new tools in real time as part of a stateful agent session. And…

Open-source & web based MCP client. Chat with any MCP server in your own app. Powered by CopilotKit & Composio. Shipped this with cursor over the weekend and built: 1. The first web-based MCP client (deployed version on GH) 2. An open-source client you can add into any app. Built using CopilotKit for the client and interactivity layer + agent frontend which connects to a LangGraph ReAct agent that coordinates MCP calls. Uses Composio's MCP server.

As a consultant I foot my own Cursor bills, and last month was $1,263. Opus is too good not to use, but there's no way to cap spending per session. After blowing through my Ultra limit, I realized how token-hungry Cursor + Opus really is. It spins up sub-agents, balloons the context window, and suddenly, a task I expected to cost $2 comes back at $8. My bill kept going up, but was I really going to switch to a worse model? No. So I built l6e: an MCP server that gives your agent the ability to budget. It works with Cursor, Claude Code, Windsurf, Openclaw, and every MCP-compatible application.…

Hello HN, we're Andrew and Stephen from Keyboard (https://www.keyboard.dev/). After building AI tools for the past year, we recently made a YouTube video on building MCP servers and realized MCP is a total game-changer. It essentially lets AI do anything by connecting to your apps. But the deeper we dove, the clearer it became that security and privacy were complete afterthoughts. Coming from backgrounds at Okta and Stripe, this made us pretty uncomfortable. We kept seeing the same pattern: every app needs its own MCP server, each storing sensitive tokens, with minimal…

Hi HN! I'm Noah, an ordinary guy that got really interested in MCP about a month ago when I downloaded Cursor. It's been super exciting to see companies around the world launch their own MCP servers empowering AI to do more. Unfortunately, I got a bit overwhelmed setting up MCP servers across my clients like Claude Desktop, Cursor, and Claude Code, so I figured I'd take a shot at building an open-source tool to help others and myself! So yeah, I built a CLI tool that enables you to quickly get MCP servers from the Web integrated with your clients like Cursor and Claude Desktop. You can use…

Many developers have faced the challenge of running MCP Servers locally, manually setting up numerous dependencies, retrieving access tokens and low quality. At Klavis, we've made this process simple with just two commands. Starting today, it's easy to pull our MCP Server Docker image to instantly spin up any of our high-quality MCP Server. From https://github.com/Klavis-AI/klavis, it is as simple as: docker run -p 5000:5000 -e AUTH_DATA='{"access_token":"ghp_your_github_token"}' ghcr.io/klavis-ai/github-mcp-server:latest Or use our managed OAuth service: docker…

I'm Fenil, co-founder/CEO of OpenFunnel (YC F24), building this with my co-founder/CTO Aditya. We're launching OpenBenchmarks (https://openbenchmarks.com), open-source, reproducible benchmarks for SaaS APIs, starting with the category we know best: GTM APIs. ## Why we built this More and more B2B software evaluation will/already runs through reasoning models inside agentic workflows rather than through people. And buyers increasingly pick vendors that are API-first and ship MCPs, so they can wire them into internal workflows. Strong reasoning models are skeptical of…

Problem: LLMs need context data to give accurate answers and thousands of great publicly available datasets remain vastly unexploited. Anthropic’s MCP servers are awesome, but we need many more servers and an easy way to discover them. What if it took only one command to connect any LLM to any open dataset? Open Data MCP, a 2-in-1 solution: 1. Access Open Data: - 10 seconds setup to query any integrated Open Data MCP server from Claude (and more to come) - Simple CLI tool 2. Access Open Data: - Create your own Open Data MCP server(s) - Get templates, guides, and community - Get instant…

I built a simple multi user, multi board, Task/Kanban MCP server. I have been looking for something like this to manage development agents, but I wasn't seeing anything that felt like what I wanted. So I set down and decided to vibe code an alternative. While it was an experiment at first I have been using it daily for my personal development projects and I really think there are others who might be looking for exactly this. It's 100% a WIP, but it is also very usable. I have a demo instance running at https://mootasks.dev. If you find this interesting I'd appreciate a star.…
