Capabilities

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.

Sends data to a third-party sink lib/webhooks.ts:100, lib/slack.ts:74
    return new URL(raw).hostname === "hooks.slack.com"

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.

Sanction — questions

Answers built from our own checks of this server.

Is Sanction working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 2 of 91 checks got a reply (2.2%), average response time 331 ms. The bar chart above shows every period we have measured.
The registry lists Sanction as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Sanction?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Sanction need an API key?
No. Sanction completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. This is what we observed, not what the docs claim.
How fast is Sanction?
It answers our handshake in 331 ms on average, which is faster than 42% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use Sanction?
The npm package sanction-mcp was installed 143 times in the last week. Week over week that is +374%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Sanction open source?
The code is open source: it is published under the MIT licence, written in TypeScript and 3 stars on GitHub. The licence covers the code in the repository, not the hosted service at getsanction.com, which runs on its operator's own terms.
