Server instructions

Stack Facts: signed, dated answers on software end-of-life dates (endoflife.date), actively exploited CVEs (CISA KEV) and LLM prices. Pay per call in USDC: no account or API key, no daily cap, up to 50 items per call. Free tools (preview, try, index, validate, manifest, keys) answer here. Paid tools answer isError with an x402 offer: pay over HTTP by sending the given request to the given url with a PAYMENT-SIGNATURE header (x402 v2) or an X-PAYMENT header (x402 v1; the HTTP 402 body is the v1 offer).

Check dependencies or a lockfile for vulnerable and malicious packages: up to 50 purls, or a package-lock, yarn.

Inferred read-only

stackfacts_preflight

Call before installing a package an LLM suggested: one npm, PyPI or purl version against OSV, CISA KEV and EOL data.

Inferred read-only

Inferred read-only

stackfacts_package_card

Get an npm or PyPI package's latest version, publish dates, deprecation or yank, SPDX licence, repository and runtime range.

Potential side effects

stackfacts_license_check

Call before adding a dependency: check SPDX licences or packages against your project licence and use, with a compatibility verdict per item.

Inferred read-only

stackfacts_cve_prioritize

Call before patching: rank up to 100 CVEs by CISA KEV status, then FIRST EPSS exploit probability score and percentile.

Inferred read-only

stackfacts_cve_search

Find CVEs by keyword or package name in CISA KEV and OSV (not all of NVD), with KEV status, EPSS score, and CVSS v3 where an OSV advisory has one.

Inferred read-only

stackfacts_package_preflight

Call before installing an npm or PyPI package: latest version, licence, OSV vulns, CISA KEV CVEs, deprecation or yank.

Check moving an npm or PyPI package from one version to another: advisories fixed or introduced, KEV, licence, runtime.

Inferred read-only

stackfacts_lockfile_diff

Check two npm or PyPI package lists (purls): version changes with advisories fixed or introduced, KEV, licence, runtime.

Inferred read-only

stackfacts_stack_watch
