n8n
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: Auto-Add Captions to Every Video Your Team Uploads (n8n + FFmpeg) | dev.to | 2026-06-12You'll need an n8n instance (cloud or self-hosted), an FFmpeg Micro API key from ffmpeg-micro.com, and a cloud storage folder your team already uses for video files.

LobeHub
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 | 2026-03-24You 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!

Project mention: I got tired of copy-pasting GitHub issues into AI chats. So I fixed it. | dev.to | 2026-04-10
What really inspired this was Context7. Watching it fetch fresh docs as a subagent made something click:

Project mention: CLI over MCP: a small Chrome DevTools experiment in Copilot CLI | dev.to | 2026-06-10
I ran the same browser smoke task through two paths: direct Chrome DevTools MCP and a custom CLI skill around mcp2cli. In GitHub Copilot CLI with gpt-5.3-codex-medium, direct Chrome DevTools MCP added about 5k tokens of upfront context before the agent did any work. The runtime table is too small and too noisy to rank the tools. The useful question is where the agent pays to discover the browser-control surface.

AI Agents & MCPs & AI Workflow Automation • (~400 MCP servers for AI agents) • AI Automation / AI Agent with MCPs • AI Workflows & AI Agents • MCPs for AI Agents
Project mention: The AI Harness: why your AI coding agent is only as smart as the repo you put it in | dev.to | 2026-05-01Hi. I am an engineer at Activepieces, an open source automation platform (think Zapier, but you can self host it and read the source code). I write TypeScript for a living. I argue with bots about tabs vs spaces now. And our team spent the last few months really, really invested in one question:

context-mode
Context window optimization for AI coding agents. Sandboxes tool output, 98% reduction. 15 platforms
Project mention: Show HN: Context Mode Insight – observability layer for AI coding agents | news.ycombinator.com | 2026-06-07 -

Project mention: I shipped a fix. The PR got closed. And that’s exactly how open source works sometimes 🙂 | dev.to | 2026-02-07
PR for context: https://github.com/triggerdotdev/trigger.dev/pull/3014

It's convenient to place the rules in a separate directory. For example, create a .cursor folder in the project root and put all rules inside a rules folder within it. Be sure to give the AI agent a link to the rules. Here's also an example of a detailed set of rules from another project configured with Framelink MCP:

OpenMetadata
The Open Context Layer for Data and AI , OpenMetadata is the open platform for building trusted data context and business semantics for humans, AI assistants, and agents.
Project mention: Show HN: Marmot – Single-binary data catalog (no Kafka, no Elasticsearch) | news.ycombinator.com | 2025-12-02Great to see Marmot here and I'm a huge fan of your project. Recently, we deployed a catalog but we went with open-metadata https://open-metadata.org/ another amazing project.
What we missed on marmot was existing integrations with Airflow and other plugins like Tableau, PowerBI etc. We're an enterprise and needed a more mature product. Fingers crossed marmot reaches there soon.

gateway
A blazing fast AI Gateway with integrated guardrails. Route to 1,600+ LLMs, 50+ AI Guardrails with 1 fast & friendly API.
Project mention: gateway VS bifrost - a user suggested alternative | libhunt.com/r/gateway | 2026-05-26 -
claude-context
Code search MCP for Claude Code. Make entire codebase the context for any coding agent.
Claude Code doesn't do anything with semantic search or embeddings out of the box. They use a simple grep tool instead.
Neither does OpenAI's Codex CLI - you can confirm that by looking at the source code https://github.com/openai/codex
Cursor and Windsurf both use semantic search via embeddings.
You can get semantic search in Claude Code using this unofficial plugin: https://github.com/zilliztech/claude-context

Project mention: VoltAgent Just Asked Us to Build Their Guardrail Provider Interface. Here Is What We Shipped. | dev.to | 2026-03-20
VoltAgent is a 6.8k-star TypeScript framework for building AI agents. They already had InputGuardrail and OutputGuardrail types — handler functions that run before and after model calls.

mcp
Browser MCP is a Model Context Provider (MCP) server that allows AI applications to control your browser (by BrowserMCP)
Project mention: Creating an Automated UI Test of Your Web App in Seconds, with Gemini CLI and BrowserMCP | dev.to | 2026-01-14Jack Wotherspoon had shared his most recent weekly bulletin describing the latest advancements in Gemini CLI. He mentioned “Multi-Modal MCP Tool Responses” as one of the new features, meaning that Gemini CLI can now interpret and act on MCP responses of various modalities, not just text. He happened to mention BrowserMCP which I’ve never before looked at.
