SafeNode MCP Gateway runs on your own machine — the client starts it, so there is no endpoint to ping. 34 installs a week from npm. Last commit 18 Oct 2026.
Policy proxy for MCP tool calls. A denied call never reaches the downstream server.
What the code does
We read the source, 1 d ago · rules 995398eba69f
What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.
# Placeholder so the demo config validates. Override with a real key to evaluate anything. ENV SAFENODE_API_KEY=sn_demo_key_not_valid_for_evaluation
Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
This code can reach further than it looks
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.
