MCP server for Q402. Gasless USDC/USDT/RLUSD/Q payments on 12 EVM chains (USDG on Robinhood Chain), Q402 Yield (gasless supply and withdraw into Aave, Lista, and Morpho lending vaults), gasless non-custodial escrow (create, fund, release, refund, dispute), Q staking, a Chainlink CCIP USDC bridge on the eth/avax/arbitrum triangle, and RedStone NAV/price triggers (autonomous gasless payout on a feed crossing), and read-only treasury Memory (spend summaries, vendor history, per-agent spend reports). 46 tools, callable from Claude (Desktop / Code), OpenAI Codex CLI, and any other Model Context Protocol client.
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.
1 critical finding reported by agent-audit-kit. The composite score alone does not reflect this — read the per-scanner reports below.
This artifact ships from 2 sources and their verdicts differ. The worst is github (Flagged). Installing from a cleaner source does not mean the others are safe — check the source you actually install from.
github: https://github.com/quackai-org/q402-mcp, 120 findings
Choose your runtime: the CLI writes the mcpServers config entry for that target.
nerlo install --target claude-code -- @quackai/q402-mcp
Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.
6 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 100 findings across every scanner that examined this package. None of the 1 finding rated critical by their scanner were dismissed.
Two keys had to turn. The model had to name a reason from a fixed list of six, and a deterministic check of ours — over which files this artifact actually installs — had to independently agree. Anything it could not corroborate is in “not reviewed” above, at full severity.
2 Documentation or example — The match is in documentation or sample code, confirmed by our own check to be outside the installed artifact.

2 Test or fixture file — The match is in a test or fixture. Our own check confirmed the file is not part of what gets installed.

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 DNS rebinding and secret exfiltration to network
The artifact contains a critical DNS rebinding vulnerability in `src/travala/live-adapter.ts`. It also exhibits high-severity behavior of exfiltrating secrets to network egress across multiple files, including `src/client.ts` and various tools. Additionally, the artifact handles OAuth credentials and integrates with an Anthropic SDK, which warrant attention.
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.
