// key findings
⚠️
Known vulnerabilities in dependencies: 3 high
Affects packages this MCP installs at runtime. Upgrade or remove the affected dependency.
✅
No credential exfiltration, no sensitive file access, no obfuscation
Static analysis found nothing flowing your secrets to unexpected places.
✅
Open source with a license and README
Anyone can audit the code, the license is declared, and the publisher documents what it does.
🔐
You'll be asked for 2 credentials: PI_API_KEY, SNOTRA_API_TOKEN
These are read from process.env at runtime. Make sure you trust where they’ll be sent.
// tools this server exposes3 tools

These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.

web_search

Search the web and return results with URLs, titles, and snippets.

web_fetch

Fetch the full content of a web page. Use this to read articles, documentation, or any web page content. Provide a URL to get its readable text content.

get_current_time

Get the current date, time, and timezone. Use this when you need to know the actual current time.

// known CVEs in dependencies3 high1 medium8 low

Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

highnodemailer@6.10.1GHSA-2x7j-588g-ccc2

Nodemailer: Quadratic (O(n²)) time complexity in addressparser allows remote denial of service via a crafted address list

highnodemailer@6.10.1GHSA-p6gq-j5cr-w38f

Nodemailer: Message-level raw option bypasses disableFileAccess/disableUrlAccess, enabling arbitrary file read and full-response SSRF in the delivered message

Nodemailer’s addressparser is vulnerable to DoS caused by recursive calls

Dependencies

12 runtime dependencies, 1 flagged: puppeteer-core

Tool annotations

No tools have read-only/destructive annotations

Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.

All four hints declared on every tool

3/3 tools missing one or more hints — web_search (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); web_fetch (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_current_time (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint). OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

Tool test coverage

1/3 tools referenced in tests (33%)

Write tests that reference each tool by name so every tool has at least one test.

Shell command execution

2 calls in production code run through a shell (extension-runtime.mjs:542, extension-runtime.mjs:588)

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

Production dependencies are patched

0 critical, 3 high severity in production deps — nodemailer@6.10.1 (high), nodemailer@6.10.1 (high)

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

// 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.
