RelayShield Security Intelligence runs on your own machine — the client starts it, so there is no endpoint to ping. 451 installs a week from pypi. Last commit 7 Sep 2026.
Breach, SIM swap, infostealer, domain lookalikes, MCP registry risk, prompt-injection detection.
What the code does
We read the source, 20 h ago · rules 3dff92dd89df
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.

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.

}This one needs environment variables set before it will start:
RELAYSHIELD_API_URL (RelayShield API base URL — https://api.relayshield.net), RELAYSHIELD_API_KEY (RelayShield API key for subscription access (all tools available) — get one at api.relayshield.net/developers), RELAYSHIELD_X_PAYMENT (x402 payment proof — USDC on Base (pay-as-you-go mode, no API key needed)).
The author declared them in the registry entry; get the values from the project itself.
