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.

Checks whether it runs in a sandbox hefesto/telemetry/client.py:284
        if os.path.exists("/.dockerenv"):
        subprocess.run(["git", "clone", "--depth", "1", url], check=True)
Runs with shell=True hefesto/hooks/pre_push.py:35
            shell=True,
Touches key and credential files hefesto/analyzers/devops/dockerfile_analyzer.py:112
                r"\.env|\.pem|\.key|id_rsa|id_ed25519|credentials|\.npmrc|\.pypirc|\.netrc"
In the project's build, not in the package

Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.

Builds a database query by concatenation .github/workflows/traffic-report.yml:52
      - name: Create or update traffic-report issue
        if: ${{ github.event_name == 'schedule' || inputs.post_issue == 'true' }}

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.

HefestoAI — questions

Answers built from our own checks of this server.

What can HefestoAI do?
It exposes 4 tools, read directly from the server on our last check. Among them: analyze, compare, install, pricing. 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 HefestoAI working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 21 of 91 checks got a reply (23.1%), average response time 757 ms. The bar chart above shows every period we have measured.
The registry lists HefestoAI 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 HefestoAI?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does HefestoAI need an API key?
No. HefestoAI 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.
How fast is HefestoAI?
It answers our handshake in 757 ms on average, which is faster than 16% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is HefestoAI open source?
We cannot say either way: written in Python, 7 stars on GitHub and 2 open issues, but we could not determine the licence, and without one the code is not open source by default.
