Reference MCP – let your AI agents search each other's past sessions
I was tired of asking my claude code to reference my codex chats to get references to what decisions it made and why ; so I built Reference MCP It, whenever prompted establishes sessions to get direct access - been using it on my system for a bit and was super helpful so I made a repo :) Would love feedback!

What it does
Let your AI agents search each other's past sessions. - Kuberwastaken/reference
One MCP server you register in each tool. It reads every tool's session transcripts and memory files ( CLAUDE.md , AGENTS.md , …) from your machine — so any agent can recall what any of them did before. Claude Code forgets what you did in Codex; Codex can't see your Claude history; Cursor knows neither. Reference fixes that. I kept asking Claude Code to go reference my Codex chats — to dig up what decisions it had made and why . Doing that by hand got old fast, so I built Reference . Whenever it's prompted, an agent establishes sessions to get direct access to your history across tools. I've been running it on my own system for a bit and it's been genuinely helpful — so I cleaned it up into…from github.com

Retain – A unified knowledge base for all your AI coding conversationsJan 2026 · github.com · ▲45Hey HN! I built Retain as the evolution of claude-reflect (github.com/BayramAnnakov/claude-reflect). The original problem: I use Claude Code/Codex daily for coding, plus claude.ai and ChatGPT occasionally. Every conversation contains decisions, corrections, and patterns I forget existed weeks later. I kept re-explaining the same preferences. claude-reflect was a CLI tool that extracted learnings from Claude Code sessions. Retain takes this further with a native macOS app that: - Aggregates conversations from Claude Code, claude.ai, ChatGPT, and Codex CLI - Instant full-text…
A "Codebase" as an MCP Server2025 · github.com · ▲20We built a reference MCP server that lets your editor/agent learn a codebase directly from source (signatures, types, AST, comments). Docs are optional. The reference impl runs on our open-source project’s codebase. Why we built it Docs are important, but they add another abstraction layer between your code and your users. Keeping them at the right quality is hard (especially at a startup), and LLM-generated docs are often mediocre until you invest real polish. Exposing code to the model in a structured way keeps answers grounded and current, and it’s always available. You can even…
CoChat MCP – Let your team review what your coding agent is buildingFeb 2026 · github.com · ▲5I built an MCP server that connects coding agents (Claude Code, Cursor, OpenCode, Codex) to a collaborative workspace where your team and other AI models can review what the agent is planning. The problem: When Claude Code creates an implementation plan, it lives in your terminal session. Nobody else sees it until it becomes a PR. If you want GPT to check the architecture or a teammate to flag issues, you're copy-pasting between windows. This MCP server fixes that. When your agent creates a plan, it gets shared as a collaborative thread in CoChat. Engineers comment on it, other AI models…

Homebrew 6.0.0▲1,481Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
