12 MCPs published
A published suite of MCP servers that give AI agents real tools: browser automation over Puppeteer, GitHub and Jira/Atlassian, AWS CloudWatch Logs, Azure AD device-code auth, MySQL, SonarCloud, Kafdrop, Obsidian and a self-hosted Onyx knowledge base, plus an automated code-review agent. One monorepo, one registration command per host, and they work with any agent rather than a single vendor's.

22 repositories
The largest is a Node.js back-end framework comparison: the same TODO API built in Nest, Express, Koa, Fastify, Next and vanilla Node, then benchmarked side by side. Around it: local-LLM translation tooling (including a Ren'Py visual-novel translator that runs on modest hardware), Windows provisioning and microservice quickstart scripts, a design patterns reference, and Google Apps Script snippets.
