  This repository is a synthetic security-test artifact from the Layerfault
  corpus. It intentionally contains adversarial characteristics (e.g.
  suspicious pickle opcodes, executable-format smuggling, prompt-injection
  strings) designed to exercise security scanner detection rules. It is
  **not** a usable ML model and must never be loaded or executed outside an
  isolated scanner-testing environment. By accepting, you confirm you
  understand this repository is a test fixture, not production model
  weights.

> **SECURITY TEST ARTIFACT: DO NOT USE AS A PRODUCTION MODEL**

This repository is part of the Layerfault synthetic security corpus.
It is deliberately constructed to contain security-relevant characteristics for scanner testing.

**Corpus ID:** `LF-CORPUS-MCP-0001`

## Purpose

Static MCP configuration combining plaintext transport, URL credentials, fake env credentials, overbroad scopes, unpinned npx, auto-confirm and contradictory tool annotation.

## Direct expected Layerfault rules

- `LF-MCP-TLS-ABSENT`
- `LF-MCP-CREDENTIAL-IN-URL`
- `LF-MCP-CREDENTIAL-ENV-EXPOSURE`
- `LF-MCP-SCOPE-OVERBROAD`
- `LF-MCP-SUPPLY-CHAIN-AUTO-DOWNLOAD`
- `LF-MCP-SUPPLY-CHAIN-AUTO-CONFIRM`
- `LF-MCP-CONTRADICTORY-ANNOTATION`
- `LF-MCP-TOKEN-PASSTHROUGH-RISK`

## Candidate rules

These are deliberately plausible targets that remain marked as candidates until the exact
Layerfault build used for certification confirms them.

- `LF-MCP-AUTH-ABSENT`
- `LF-MCP-AUTH-METADATA-MISSING`
- `LF-MCP-TOKEN-AUDIENCE-UNBOUND`
- `LF-MCP-ORIGIN-UNRESTRICTED`

## Negative-control rules

These should remain silent for this corpus item.

- None

## Safety

The corpus uses fake secrets, loopback/`.invalid` network destinations, harmless marker output,
and synthetic model behavior only. It is intended for static scanning and isolated security testing.
