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.

    r = subprocess.run([sys.executable, "-m", "pytest", "tests", "-q", "--no-header", "--tb=line",
Page executes code built at runtime products/signed-cliff-check/verify.html:177
  $("cta").innerHTML = renderCta(PAYMENT_LINK_URL);

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 5

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

security
get_security_receipt
Read an unsigned, filtered public view; retain original delivery for signature verification.
security_preflight
Run a $1 static Security Preflight and return a signed receipt. Direct MCP requires the checkout caller and verified fixed-order session. The separate x402 HTTP rail retains its existing introductory quote policy. No deployed endpoint is fetched or tested. Importing the receipt into an Agent Market profile is a separate, explicit action.
describe
describe_agent
Describe scope, evidence boundary, inputs, and outputs.
scan
scan_source
$1 bounded inline VulnCanon source scan; indicators, not proven exploits. Direct MCP requires the checkout caller and verified fixed-order session. At most 64 KiB, 2000 lines, 4096 characters per line. No model calls, repository fetching or code execution. Returns a redacted signed receipt.
screen
screen_injection
$1 batch of 1–20 text samples screened for deterministic injection markers. Direct MCP requires the checkout caller and verified fixed-order session. Maximum 64 KiB total. Heuristic indicators, not calibrated probabilities or a guarantee of safety. No model calls or automatic follow-on purchase.

Security Preflight — questions

Answers built from our own checks of this server.

What can Security Preflight do?
It exposes 5 tools, read directly from the server on our last check. Among them: describe_agent, get_security_receipt, scan_source, screen_injection, security_preflight. 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 Security Preflight working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 183 of 183 checks got a reply (100.0%), average response time 375 ms. The bar chart above shows every period we have measured.
How do I connect Security Preflight?
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 Security Preflight need an API key?
No. Security Preflight completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Security Preflight?
It answers our handshake in 375 ms on average, which is faster than 36% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Security Preflight open source?
The code is open source: it is published under the Apache-2.0 licence, written in Python, 0 stars on GitHub and 4 open issues. The licence covers the code in the repository, not the hosted service at mcp.viridisconservation.com, which runs on its operator's own terms.
