You'll be asked for 3 credentials: ETHERSCAN_API_KEY, SUBQL_ACCESS_TOKEN, SUBQL_PRIVATE_KEY
These are read from process.env at runtime. Make sure you trust where they’ll be sent.

No eval / new Function

1 eval() or new Function() call — dynamic code execution

Replace eval / Function with explicit parsing or safer alternatives.

Shell command execution

4 calls in production code run through a shell (src/createProject.fixtures.ts:73, src/controller/init-controller.ts:113, src/controller/init-controller.ts:354)

Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.

Production dependencies are patched

1 critical, 5 high severity in production deps — simple-git@3.28.0 (critical), @modelcontextprotocol/sdk@1.24.3 (high)

Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

Dev dependencies

5 critical/high in dev-only deps (does not ship to users)

Upgrade dev dependencies when convenient.

Dependency freshness

5/38 production deps abandoned (no release in 2+ years): fuzzy@2022-06-18 (4.2y), qrcode-terminal@2022-06-25 (4.2y), json5@2023-03-04 (3.5y)

Domain consistency

npm scope @subql doesn't match GitHub owner subquery

Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 5 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
