Top 23 mcp Open-Source Projects

1. n8n

   1 454 191,300 10.0 TypeScript

   n8n is a workflow automation platform for building AI-powered workflows and agents, connecting any AI model to any business system with full control over data, security, and deployment. Build visually or in code while n8n handles infrastructure from prototype to production with fully auditable executions.

   

   Project mention: SOC-in-a-Box: One LLM, Eight Hats, A Production-Bar AI SOC on a Single GPU | dev.to | 2026-06-06

   n8n and similar visual workflow tools were on the list for one specific reason: leadership likes seeing the boxes-and-arrows. But the LLM nodes aren't first-class — you'd be wrapping every model call in HTTP, and the graph is in a database, not in code that's reviewable in a PR. Auditability and reproducibility are both worse than the LangGraph + bus path. (n8n is a great fit for non-LLM SOAR-style automations, just not for this.)

   Production-ready platform for agentic workflow development.

   

   Project mention: Bringing MongoDB Atlas and Voyage AI to Dify: Build RAG Workflows and Data Agents Without Heavy Glue Code | dev.to | 2026-05-31

   The MongoDB extensions for Dify help close that gap.

4. open-webui

   3 61 139,852 10.0 Python

   User-friendly AI Interface (Supports Ollama, OpenAI API, ...)

   

   Project mention: Quick and easy local AI RAG setup with JetBrains IDE integration and browser UI | dev.to | 2026-06-02

   To get a local web UI (that is very similar to CharGPT) that supports Retrieval Augmented Generation (RAG), workflows and many other features, we'll use Open WebUI (https://github.com/open-webui/open-webui). Although it can be setup using locally installed Python, I've decided to try out their Docker image instead. Since I have an Nvidia card, I've used their Nvidia GPU supported docker image.

5. cc-switch

   4 3 90,508 9.9 Rust

   A cross-platform desktop All-in-One assistant for Claude Code, Codex, OpenCode, OpenClaw, Gemini CLI & Hermes Agent. Only official website: ccswitch.io

6. ragflow

   5 18 81,919 10.0 Python

   RAGFlow is a leading open-source Retrieval-Augmented Generation (RAG) engine that fuses cutting-edge RAG with Agent capabilities to create a superior context layer for LLMs

   

   Project mention: I Scanned 5 Popular Open-Source AI Projects for EU AI Act Compliance. Here's What I Found. | dev.to | 2026-03-31

   I ran AIR Blackbox (the scanner itself), Browser Use (79K+ stars), RAGFlow (76K+ stars), LiteLLM (23K+ stars), and Superlinked (15K+ stars) through the same compliance checks.

7. Netdata

   6 130 79,077 9.9 C

   The open-source observability platform everyone needs

   

   Project mention: OpenTelemetry Profiles Enters Public Alpha | news.ycombinator.com | 2026-03-26

   > Like… has anyone done a Jepsen-like stress test on rsyslogd and shared the results? I’ve half-assedly looked before and not been able to find anything.

   I've not used rsyslogd specifically, but I don't see how you'd have any issues with the log volume you described.

8. LobeHub

   7 20 78,186 10.0 TypeScript

   The ultimate space for work and life — to find, build, and collaborate with agent teammates that grow with you.

   

   Project mention: Show HN: AI Roundtable – Let 200 models debate your question | news.ycombinator.com | 2026-03-24

   You can set this up yourself with API keys to the corresponding providers and creating an Agent Group in https://github.com/lobehub/lobehub. Agent groups allow you to easily create a room of agents and have them discuss any of your topics. Easily make agents with types and skills, it even assists in drafting starting prompts and even team members depending what your query (and selected model) is.

   You can self-host as well, but not via desktop app. Sever setup required.

   Be careful of your token context, you can easily rack up costs if you leave Opus selected as the model and get lost in some rabbit hole of results.

   Enjoy enjoy!

9. anything-llm

   8 48 61,083 9.7 JavaScript

   Stop renting your intelligence. Own it with AnythingLLM. Everything you need for a powerful local-first agent experience

   

   Project mention: NVIDIA RTX Spark: What the Backlash Gets Wrong About AI on Your Desktop [2026] | dev.to | 2026-06-04

   The headline marketing number is "1 petaflop" of AI performance. Sounds staggering. Tim Carambat, creator of AnythingLLM and one of the most credible voices in the local AI developer community, has already questioned this figure. His point is one I've validated repeatedly in my own benchmarking: for running large language models locally, memory bandwidth is the actual bottleneck, not raw FLOPS. You can have all the tensor cores in the world, but if you can't feed them data fast enough, your Llama 3 inference is still going to crawl.

10. Scrapling

    9 9 60,673 9.8 Python

    🕷️ An adaptive Web Scraping framework that handles everything from a single request to a full-scale crawl!

    

    Project mention: I Tested Every Web Scraping Tool Against Lazada — Here's What Actually Works (May 2026) | dev.to | 2026-05-29

    I came across Scrapling through a recommendation on X and decided to put it through its paces — not against a demo page, but against Lazada Singapore, a production site with Google reCAPTCHA and a custom slider verification. The setup: a single 4GB VPS, no residential proxies, no credits, just open-source tools.

    Project mention: DeepSeek reasonix, engineered for low token cost during long running sessions | news.ycombinator.com | 2026-05-24

    Maybe check out Goose. It is the standard agent harness being developed by The Linux Foundation under the AAIF. Under active development and the implementation seems to have a good leg up on the other popular agents.

18. Kong

    17 22 43,520 7.0 Lua

    🦍 The API and AI Gateway

    

    Project mention: Show HN: ArchGW – an intelligent edge and service proxy for agents | news.ycombinator.com | 2025-07-12

    Nice project but there are several dozens of AI gateways now.. all kind doing the same thing. Kong AI gateway [1] was maybe the first to attack the LLM traffic governance and is indeed far ahead in both features and adoption. Trying to understand the value add and differentiator here, since is a problem kinda solved already.

19. chrome-devtools-mcp

    18 17 42,973 9.8 TypeScript

    Chrome DevTools for coding agents

    

    Project mention: WebMCP Is the Quiet Google I/O Announcement That Could Make Web Apps Agent-Ready | dev.to | 2026-05-24

    That sounds small until you compare it with the tool that exists today: Chrome DevTools MCP, Google's official MCP server that lets coding agents control and inspect Chrome through DevTools.

24. playwright-mcp

    23 45 33,458 9.6 TypeScript

    Playwright MCP server

    

    Project mention: Playwright MCP vs Rendershot MCP: choosing a browser MCP server in 2026 | dev.to | 2026-05-27

    Playwright MCP (microsoft/playwright-mcp) is an MCP server from the Playwright team that exposes ~45 tools letting an LLM drive a real browser — Chromium, Firefox, or WebKit — running locally. It sends the agent the page's accessibility tree (not screenshots) as the primary way to "see" pages, which makes it deterministic and token-cheap. You install it as npx @playwright/mcp@latest inside Claude Desktop, Cursor, Claude Code, Goose, or any MCP-compatible client.
