Tip: Astrix MCP Secret Wrapper — Pull Secrets from Vault at Runtime Instead of Storing on Disk

Astrix Security·medium signal

Astrix released an open-source MCP Secret Wrapper that sits in front of any MCP server and pulls credentials from a secure vault at runtime, so secrets never touch the host machine's disk or environment variables. Given the recent OAuth grant attack surface findings, this is a concrete hardening step: wrap your MCP servers so that even if the server process is compromised, credentials aren't locally extractable.
