codebase-memory-mcp
High-performance code intelligence MCP server. Indexes codebases into a persistent knowledge graph — average repo in milliseconds. 158 languages, sub-ms queries, 99% fewer tokens. Single static binary, zero dependencies.
Project mention: Google's Ax and Anthropic's Financial Services Are Trending — But Who Solves Long-Running Workflow Resilience? | dev.to | 2026-09-23DeusData/codebase-memory-mcp indexes codebases into a persistent knowledge graph. It solves the "context loss" problem in long-running agent tasks — agents don't have to re-read the entire codebase every time.
-
claude-task-master
An AI-powered task-management system you can drop into Cursor, Lovable, Windsurf, Roo, and others.
Project mention: TaskMaster (26K) captures 100% of prompts and responses, sendDefaultPii:true | news.ycombinator.com | 2026-04-04 -

Unity-MCP
AI Skills, MCP Tools, and CLI for Unity Engine. Full AI develop and test loop. Use cli for quick setup. Efficient token usage, advanced tools. Any C# method may be turned into a tool by a single line. Works with Claude Code, Gemini, Copilot, Cursor and any other absolutely for free. (by IvanMurzak)

Also in this issue: Matt Nigh analyzed 2,500+ repositories to figure out what makes AGENTS.md files actually useful (spoiler: most aren't), browser fingerprinting via favicon is both creepy and clever, PrinceJS lands in the top 3 performance benchmarks despite being "the smallest backend framework ever," and privacy fans get Ackee for self-hosted analytics. Ultracite brings zero-config linting with opinions baked in, and zerobyte automates backups for self-hosters who want to set it and forget it.
-
Chaterm
Open source AI terminal for cloud and infrastructure management, enabling you to deploy, troubleshoot, and automate services using natural language and intelligent agents.

Project mention: LNAI – Define AI coding tool configs once, sync to Claude, Cursor, Codex, etc. | news.ycombinator.com | 2026-02-03
Is this substantially different than https://github.com/intellectronica/ruler? Or how would you differentiate?
-
DevDocs
Completely free, private, UI based Tech Documentation MCP server. Designed for coders and software developers in mind. Easily integrate into Cursor, Windsurf, Cline, Roo Code, Claude Desktop App (by cyberagiinc)
-
mcp-unity
Model Context Protocol (MCP) plugin to connect with Unity Editor — designed for Cursor, Claude Code, Codex, Windsurf and other IDEs
Community projects, like those from CoplayDev and CoderGamester, focus on speed and flexibility. They expose many parts of the Unity editor as MCP tools, which makes them great for experimentation and fast iteration.

Project mention: Ask HN: Is there a free MCP for web and documentation search? | news.ycombinator.com | 2026-01-17
* https://github.com/arabold/docs-mcp-server: I didn't test this, but I was turned off by the fact you have to run the server in the background instead of allowing it to be booted by the Codex instance (via npx) like it can for other kinds of MCP servers.
Does anyone have a solution to this that hits on all marks: free, able to read websites including JS ones, thorough and high-quality?
-
context-engineering-kit
Hand-crafted Claude Code Skills focused on improving agent results quality. Compatible with OpenCode, Cursor, Antigravity, Gemini CLI, and others. Includes CodeRabbit open-source alternative.

react-compiler-marker
Universal IDE extension that shows which React components are optimized by the React Compiler ✨
Project mention: Will React Compiler Make Manual Memoization Obsolete? — Things to Know Before Adopting It | dev.to | 2026-01-26If you're considering adoption, I think it would be good to first enable the ESLint plugin and check how many Rules of React violations exist in your codebase. The recommended or recommended-latest presets in eslint-plugin-react-hooks include compiler-specific rules and can be used even without installing the compiler. The unsupported-syntax rule can detect unsupported syntax, though I haven't been able to confirm whether it detects finally clauses or conditional branches inside try-catch. If you want to know for certain, you might want to try it in the React Compiler Playground or use tools like react-compiler-marker.
