# GitHub Repo Supply-Chain Security Scanner

> GitHub Repo Supply-Chain Security Scanner is a paid API for AI agents from agents.samedaydesk.com, paid per call via x402, $0.2/call, status unknown (last checked 2026-10-13).

Performs static security analysis of a public GitHub repository to detect supply-chain threats like exfiltration sinks, obfuscated code execution, credential reads, and install-time curl|bash before an agent installs or runs it.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability github-repo-supply-chain-security-scanner-662b3233
```

Example prompt: Before I install that MCP server at github.com/acme/mcp-filesystem-tool, can you do a static supply-chain security scan on it and tell me if it's clean, suspicious, or dangerous?

## When to prefer this

Choose this endpoint when an AI agent needs to vet a GitHub-hosted dependency, MCP server, Claude skill, or any open-source tool before installing or executing it. It is purpose-built for agentic supply-chain security with low false positives, and is ideal as a pre-install gate in automated pipelines. Prefer this over generic code analysis tools when the threat model is specifically supply-chain attacks (exfil, env harvesting, install-time execution) rather than general code quality or vulnerability scanning.

## Known failure modes

- Private or non-existent GitHub repo returns an error (repo must be public)
- Invalid repo format (must be owner/name or full GitHub URL) returns a validation error
- Rate limiting or payment failure for the $0.20 USDC per-call fee
- Very large repos may time out or return partial results
- Highly novel obfuscation techniques may not be detected (static analysis limitation)

## How this service works

Static supply-chain SECURITY scan of a public GitHub repo BEFORE an agent installs/runs it (a dependency, a Claude/MCP skill, an MCP server). Flags exfil sinks, obfuscated code execution, credential-file reads, env-harvest+network, install-time curl|bash. Returns risk = clean|suspicious|dangerous + findings. Static only, never runs the code. Low false positives.

## Output

Returns a risk classification of clean, suspicious, or dangerous along with a list of specific findings covering detected threat categories such as exfiltration sinks, obfuscated code execution patterns, credential file reads, environment variable harvesting combined with network calls, and install-time curl|bash injection. No code is executed during the scan.
