Questions
What is the RAGStack MCP server?
Search, chat, upload, and scrape a serverless RAGStack knowledge base on AWS.
What tools does RAGStack expose?
15 in total: 11 read-only, 4 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.
Is RAGStack safe to connect to an agent?
No — not without reading the findings first. The audit graded it D (69/100) and found 4 critical or high issues in the source. Each one is listed on this page with the file and line it is on.
What credentials does RAGStack need?
It reads ADMIN_PASSWORD, METADATA_KEY_LIBRARY_TABLE, RAGSTACK_API_KEY and SAM_GRAPHQL_API_KEY from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.
How does RAGStack run?
It speaks stdio, so it runs as a local process your client starts. It is published on npm as ragstack-ui at 1.0.0.
How current is this page?
The grade is for one exact copy of the source (e4662e8b8b27), read on 2026-10-09. The repository is watched and re-audited when it changes.
