GhostFree
A local MCP server that scans repository dependencies for known vulnerabilities (CVEs) using OSV.dev, enriches findings with NVD and CISA KEV data, and supports triage, remediation, and accepted risk management directly from an AI coding assistant.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
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.
list_accepted_risksList all accepted CVE risks, including whether each acceptance has expired.
accept_riskRecord an accepted risk for a CVE, with a reason and mandatory expiry date. Expiry beyond 1 year requires confirm_extended_expiry=true.
remove_accepted_riskRemove a previously accepted risk by its UUID acceptance ID.
check_cvesCheck a list of packages against OSV.dev for known vulnerabilities. Returns CVEs above the severity threshold as a numbered list, suppressed/accepted risks, expired acceptances, and a count of below-threshold findings.
discover_dependenciesScan the repository for manifest files (requirements.txt, package.json, go.mod, Cargo.toml, pom.xml, *.csproj, Dockerfiles, etc.) and return all pinned dependencies grouped by ecosystem.
enrich_cveFetch enrichment data for a specific CVE ID: CVSS vectors and score from NVD, CWE weakness classification, references, and whether it appears in the CISA Known Exploited Vulnerabilities (KEV) catalog. Gracefully degrades if NVD or KEV are unavailable.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

js-yaml: YAML merge-key chains can force quadratic CPU consumption
JS-YAML: Quadratic CPU consumption in !!omap resolution (3.x and 4.x) — CVE-2026-59870 fix not backported
fast-xml-parser XMLBuilder: XML Comment and CDATA Injection via Unescaped Delimiters
JS-YAML: Quadratic-complexity DoS in merge key handling via repeated aliases
GHOSTFREE_DIROptional — use a custom directory instead of .ghostfree/ (applies to both accepted.yml and config.yml)NVD_API_KEYOptional NVD API key for higher rate limits (50 req/30s vs 5 req/30s)All four hints declared on every tool
6/6 tools missing one or more hints — list_accepted_risks (missing: idempotentHint); accept_risk (missing: idempotentHint); remove_accepted_risk (missing: idempotentHint), +3 more. 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
Only 1/6 tools referenced in tests (17%)
Write tests that reference each tool by name so every tool has at least one test.
Production dependencies are patched
0 critical, 2 high severity in production deps — js-yaml@4.1.1 (high), js-yaml@4.1.1 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
1 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
