How to use the HippoRAG MCP tools (retrieve, rag_qa, index, delete, index_stats) as long-term memory. Use when the user asks to remember, index or "add to memory" documents, notes or files, when they ask questions that may be answered by previously indexed material, or when they ask to forget or remove indexed content.
Why this score
This repo hosts 2 skills, so its 4,073 stars are split between them (about 2,037 each) for scoring.
Popularity score: 83/100 from public GitHub signals only. It shows how widely used and maintained this is, not how well it works. Not included yet: the fake-star check. The security scan is shown separately and doesn't change the score. How we rank
Security
Scanned Oct 21, 2026 at commit d5c8329422e0, with Cisco's open-source skill-scanner.
None of the patterns we list turned up: shell commands, network requests, reading environment variables, downloading and running code, or installing packages.
A scan lists patterns in the code. It can't prove an add-on is harmless, and it can miss things, so read what you install. How we scan
