Start using x402 Package Advisories
Choose your client, copy the configuration, then enable the server in your client’s MCP settings.
Run this command in your terminal, then restart Claude Code.
Claude Code
claude mcp add --transport http x402-package-advisories https://x402-package-advisories.microtools-x402.workers.dev/mcpCapabilities
Free health check. Returns service status, version, tool prices, network and the plain-HTTP x402 endpoints.
DiscoveredAudit up to 50 dependencies in one call (OSV.dev querybatch). Input: items [{ecosystem,name,version}], or packages "npm:lodash@4.17.15,PyPI:django@3.2.0", or a manifest: package.json text (dependencies, devDependencies, optionalDependencies; range minimum used) or requirements.txt text (name==version lines). You can also POST the raw package.json or requirements.txt as the body. Returns per-package vulnerable flag, vuln count, max severity, max CVSS v3, recommended upgrade and advisory list (id, CVE, severity, score, summary, fix), plus totals by severity, unique vulns and skipped entries. Vulnerability data from OSV.dev (CC-BY 4.0); package metadata from deps.dev. Bad input and upstream errors are not charged. Costs $0.01 USDC per call via x402.
DiscoveredSecurity advisories for one open-source package version (npm, PyPI, Go, Maven, crates.io, NuGet, RubyGems, Packagist, Pub, Hex...). Returns a verdict (vulnerable yes/no, vuln count, max severity, max CVSS v3 score, counts by severity, recommended upgrade version re-checked against OSV, latest stable version and whether it is affected) plus every advisory: OSV/GHSA id, CVE aliases, summary, severity label, CVSS v3 score (computed from the vector) and v4 vector, affected ranges, fixed versions, the fix for this version, published/modified dates and references. Duplicate records (GHSA vs PYSEC/GO ids with the same CVE) are merged. Also returns the version's licenses, publish date, deprecation and dependency counts from deps.dev. Omit version to check the latest stable release. Vulnerability data from OSV.dev (CC-BY 4.0); package metadata from deps.dev. Unknown packages/versions, bad input and upstream errors are not charged. Costs $0.003 USDC per call via x402.
DiscoveredPaid connectivity test: returns ok and a server timestamp. Use it to check that your x402 payment flow works end to end. Costs $0.001 USDC per call via x402.
DiscoveredFull OSV record for one vulnerability id (GHSA-..., CVE-..., PYSEC-..., GO-..., RUSTSEC-..., OSV-...): details, aliases, related ids, every affected package with ranges and versions, references, credits, database_specific fields, plus a normalized severity label and computed CVSS v3 score. Vulnerability data from OSV.dev (CC-BY 4.0); package metadata from deps.dev. Unknown ids and upstream errors are not charged. Costs $0.001 USDC per call via x402.
