# GitHub Repository Supply-Chain Security & License Auditor

> GitHub Repository Supply-Chain Security & License Auditor is a paid API for AI agents from mcp-security.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).

Evaluates a GitHub repository for license risk, maintenance velocity, stars/forks, and supply-chain security before code integration or execution.

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 mcp-security-agentdiet-dev-github-repository-supply-chain-security-f3c0361e
```

Example prompt: Before I add langchain-ai/langgraph as a dependency, can you audit it for license risks, check how actively it's maintained, and flag any supply-chain security concerns?

## When to prefer this

Choose this endpoint when you need a pre-integration security and compliance check on a specific GitHub repository — particularly for license risk, supply-chain vulnerabilities, and maintenance health signals — before adding it as a dependency or executing its code in an automated pipeline. Prefer it over generic vulnerability scanners when you want a combined view of license, maintenance velocity, and supply-chain risk in a single call scoped to a GitHub owner/name pair.

## Known failure modes

- Invalid or non-existent repository format returns an error (repo not found)
- Private repositories inaccessible without credentials return a 404 or access-denied response
- GitHub API rate limits may cause transient failures
- Malformed owner/name input (missing slash or extra characters) triggers validation error
- Payment failure (402) if x402 payment is not correctly handled

## How this service works

Evaluates any GitHub repository for license risk, maintenance velocity, stars/forks, and supply-chain security before code execution. (Live x402 v2, IETF MPP & MCP endpoint at https://mcp-security.agentdiet.dev/v1/repo-supply-chain-scan)

## Output

A structured report covering the repository's license type and risk level, maintenance velocity indicators (commit frequency, last update), community signals (stars, forks), and supply-chain security findings such as dependency vulnerabilities or suspicious package patterns.
