An MCP Server That Answers the "Why"
Axcaliver · reddit · 2026-07-19
The author introduces Rootr: a workspace that connects team documents into a graph, rather than acting as a simple document search index. Its MCP server exposes rootrask, which can traverse relationships like "decision → related docs → postmortem/runbook" to answer "why was this changed," rather than just finding "what it is."
The post mentions it supports integration via Streamable HTTP + OAuth 2.1 dynamic client registration. Clients like Claude/ChatGPT only need to add a custom connector and log in, without managing API keys separately. The author also provided two public examples to demonstrate graph-based Q&A on real codebases.
