1. anything-llm

   1 48 61,470 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.

   Project mention: Hermes Agent – Open-Source AI Agent with Persistent Memory | news.ycombinator.com | 2026-06-08

   The project in question that is asserting Hermes is copying their ideas:

   https://github.com/EvoMap/evolver

   The timeline here is pretty telling and it looks like Hermes basically points their coding agent at evolver and says "reimplement this yourself." A few days later Hermes magically sports a nearly identical feature.

6. cursor-talk-to-figma-mcp

   5 2 6,829 6.5 JavaScript

   TalkToFigma: MCP integration between AI Agent (Cursor, Claude Code) and Figma, allowing Agentic AI to communicate with Figma for reading designs and modifying them programmatically.

   

   Project mention: Speeding Up Layout from Figma with MCP and Cursor | dev.to | 2026-02-13

   MCP Cursor Talk To Figma - a bit more demanding to set up (you need to set up a local server following the instructions and run the "Cursor Talk To Figma" plugin in Figma; works even without Dev Mode access).

7. firecrawl-mcp-server

   6 1 6,555 9.0 JavaScript

   🔥 Official Firecrawl MCP Server - Adds powerful web scraping and search to Cursor, Claude and any other LLM clients.

   

   Project mention: Show HN: MCP-recorder – VCR.py for MCP servers. Record, replay, verify | news.ycombinator.com | 2026-03-06

   --target https://mcp.devhelm.io

   It works with both HTTP and stdio transports. Scenarios are defined in YAML so it works with MCP servers in any language, and there's a pytest plugin if you want tighter integration. Secret redaction and environment variable interpolation are built in.

   To make sure this actually works on real codebases, I submitted several PRs to production MCP servers: monday.com's MCP server (https://github.com/mondaycom/mcp/pull/222), Tavily's MCP server (https://github.com/tavily-ai/tavily-mcp/pull/113), and Firecrawl's MCP server (https://github.com/firecrawl/firecrawl-mcp-server/pull/175). They went from zero schema coverage to full tool surface verification with a clean schema diff available on each tool change. One big benefit is that you can do verification and replay with no API keys — deterministic responses, no live requests to real servers.

   I wrote up a deeper dive into the schema drift problem and the VCR pattern for MCP here: https://devhelm.io/blog/regression-testing-mcp-servers

8. godot-mcp

   7 1 3,300 - JavaScript

   MCP server for interfacing with Godot game engine. Provides tools for launching the editor, running projects, and capturing debug output. (by Coding-Solo)

   

   Project mention: Fixing Godot MCP in Cursor on WSL | dev.to | 2026-04-28

   If godot-mcp won't connect in Cursor on WSL, the real culprit is almost always that Cursor is a Windows app trying to launch a Linux Node binary it can't see. The fix is to set wsl.exe as the command in mcp.json and pass node plus the absolute Linux path as arguments. Two smaller gotchas usually compound the problem along the way: tildes (~) don't expand inside JSON, and JSON config files don't allow // comments.

9. brightdata-mcp

   8 20 2,448 9.0 JavaScript

   A powerful Model Context Protocol (MCP) server that provides an all-in-one solution for public web access.

   

   Project mention: 5 Production Stacks for Live Data Ingestion at Scale (Without Getting Blocked) | dev.to | 2026-05-19

   Repository: https://github.com/brightdata/brightdata-mcp License: MIT Free Tier: 5,000 requests/month Best for: High-complexity, moderate-volume targets (competitive pricing, job market analysis, funding data, SERP monitoring) where the hard problem is anti-bot, adaptive navigation, or frequent site changes; not throughput.

10. super-agent-party

13. claude-delegator

    12 1 963 - JavaScript

    Delegate tasks to Codex and Gemini directly from within Claude Code. (by jarrodwatts)

    

    Project mention: One model is a guess. Three that agree is a plan. | dev.to | 2026-05-18

    I did not invent the delegation layer. claude-delegator is a fork of Jarrod Watts' original (MIT, upstream currently quiet), fully based on his design - I kept the structure and the license.

14. mcp-jetbrains

    13 1 960 3.8 JavaScript

    Project mention: Webmcp | news.ycombinator.com | 2026-05-22

16. cloud-run-mcp

    15 2 615 9.2 JavaScript

19. Lynkr

    18 12 468 9.2 JavaScript

    Streamline your workflow with Lynkr, a CLI tool that acts as an HTTP proxy for efficient code interactions using Claude Code CLI.

    

    Project mention: LiteLLM vs Lynkr for AI Coding Workflows: Where the Token Savings Actually Come From | dev.to | 2026-06-10

    I built Lynkr, so take this as a founder comparison. I’ll keep it honest: LiteLLM is a solid provider abstraction layer. But if your goal is specifically to reduce spend in Claude Code, Cursor, or Codex-style workflows, the difference is not “which gateway supports more providers.” The difference is whether the gateway cuts tokens before they reach the model.

20. desktop

    19 4 429 8.2 JavaScript

    Agentify Desktop lets Codex/Claude/OpenCode control your logged-in ChatGPT, Claude, AiStudio, Gemini, Grok, Perplexity web sessions via MCP, parallel hidden/visible tabs, file upload + image download (by agentify-sh)

    

    Project mention: Ask HN: What are tools you have made for yourself since the advent of AI | news.ycombinator.com | 2026-06-08

    Most of it has been to maximize productivity with AI

    1) Use chatgpt pro from codex cli, opencode, claude etc as you can't get it via API. This has been the biggest boost in productivity for me as I don't have to copy and paste.

    https://github.com/agentify-sh/desktop

    2) A small gate to make sure any agent cannot run destructive rm -rf or git reset --hard commands, it has saved me many many times

    https://github.com/agentify-sh/safeexec

    3) For mac users, summarizes and speaks out loud after codex finishes a turn

    https://github.com/agentify-sh/speak
