Loading the registry…
MCP server that shopping agents ping before purchase to check merchant trustworthiness and price fairness on Base or Solana, monetized via x402 micropayments. Part of Gradient Decisions.
The publisher performed an authenticated act of publication — proving control of a namespace in the official MCP registry, or appearing in a first-party catalogue an operator curates. That establishes WHO published it. It is not a security finding, and attested artifacts carry Flagged verdicts too.
3 critical findings reported by cisco-skill-scanner, agent-audit-kit. The composite score alone does not reflect this — read the per-scanner reports below.
Choose your runtime: the CLI writes the mcpServers config entry for that target.
nerlo install --target claude-code -- merchant-check-mcp
Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.
5 of 11 scanners examined this package. The rest do not apply to it — language, ecosystem and packaging decide which analyzers can say anything, and a scanner that cannot examine an artifact reports nothing rather than passing it.

Findings in files this artifact installs stand as reported; a model re-read the rest and said which ones it believes are false positives. This is a second opinion published beside the evidence, not a correction to it: the per-scanner reports above are unchanged, every dismissed finding is still listed there at its original severity, and the score and the Flagged badge are computed from those raw severities alone. Nothing below moved them.
Out of 26 findings across every scanner that examined this package. None of the 3 findings rated critical by their scanner were dismissed.
These findings are in files this artifact installs and are not placeholder values. No false-positive basis can be corroborated for such a finding, so this review never dismisses one; they were not sent to the model and stand at their scanner's severity.

Critical risks from shell execution and DNS rebind vulnerabilities
This artifact contains critical vulnerabilities, including potential shell execution via command injection in `/repo/scripts/backtest.ts` and DNS rebind vulnerabilities in `scripts/demo-client.ts` and `scripts/mainnet-live-test.ts`. Additionally, high-severity findings indicate that secrets could be exposed through network egress in `/repo/scripts/mainnet-http-check-test.ts` and `/repo/src/categorize/model.ts`. These capabilities warrant careful review before installation.
Concern level assessed by the review: Critical. This is the review's scale, not the registry badge.
Reviewed by gemini-2.5-flash. The model sees the findings, not your code, and cannot change a score.
