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.

  "apply": "curl -X POST \"https://discord.com/api/webhooks/$WEBHOOK_ID/$WEBHOOK_TOKEN?wait=true\" -H \"Content-Type: application/json\" -d '{\"content\":\"deploy finished\"}'",
Reads files and sends them to the network cli/lib/failure.mjs:5, plugin/footgun/scanner/lib/failure.mjs:5
import { mkdirSync, readdirSync, readFileSync, renameSync, rmSync, statSync, writeFileSync } from "node:fs";

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.

Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

confirm
confirm_trap
Record that a trap is still true (or not), with optional hours lost and version seen. Needs an API key.
file
file_trap
Draft a trap after a failure was fixed. Private by default with a Pro or Team key. Public filings are checked automatically against official sources and published only when an official source confirms them. A reviewer can still act on any filing. Citing the provider's official documentation or changelog in sources helps. No API key needed. Set visibility to public to submit to the public registry.
lookup
lookup_traps
Call before writing code against a third-party API, platform, or AI tool. Returns verified, dated failure modes with fixes.
traps
search_traps
Call when a call to a third-party service fails. Paste the error text. Returns the closest verified traps with fixes.

Footgun — questions

Answers built from our own checks of this server.

What can Footgun do?
It exposes 4 tools, read directly from the server on our last check. Among them: confirm_trap, file_trap, lookup_traps, search_traps. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Footgun working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 92 checks got a reply (0.0%), average response time 107 ms. The bar chart above shows every period we have measured.
The registry lists Footgun 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 Footgun?
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 Footgun need an API key?
No. Footgun completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
Is Footgun open source?
The code is open source: it is published under the MIT licence, written in JavaScript and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at getfootgun.com, which runs on its operator's own terms.
