Google Calendar MCP server for Model Context Protocol
We found this by crawling public sources and nobody has attested to it. That is how most of the registry gets here, and it is not a mark against the artifact — it only means no authenticated act of publication is on record. An artifact can be the vendor's own and still appear here.
Choose your runtime: the CLI writes the mcpServers config entry for that target.
nerlo install --target claude-code -- @papercut/gcal-mcp
Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.
7 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.
Not reviewed is not the same as clean. Those 6 findings stand exactly as their scanners reported them, at full severity, as they would have without this review.
The model could have called any of these a false positive and did not.

6 The model called these false positives and our own check did not agree, so the dismissal was refused.

High severity vulnerabilities, including credential access and network risks.
The artifact contains high severity vulnerabilities, including potential credential access risks from OAuth implementation in `src/auth.ts` and `src/index.ts`. A DNS rebind vulnerability in `package.json` could enable network egress or internal network access. Additionally, the use of the Anthropic SDK in `src/index.ts` suggests external data transmission, and multiple high severity supply chain vulnerabilities are present in dependencies.
Concern level assessed by the review: High. 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.
