Tools & capabilities

Attestd MCP tools 4

  • check_package_vulnerabilityCheck whether a software package or infrastructure product version has known CVE vulnerabilities or a confirmed supply chain compromise. Call this before adding, updating, or recommending any npm, PyPI, or infrastructure dependency, including mid-conversation when a developer asks about installing or upgrading a package. outsideCoverage=true means Attestd has no data for that product; treat as unknown risk, not safe. Covers infrastructure products (nginx, PostgreSQL, Redis, Docker, Kubernetes, etc.) and PyPI/npm packages.
  • list_covered_productsReturns Attestd-covered products for CVE checks. With an API key, returns live data from GET /v1/products (CVE infrastructure slugs plus monitored supply chain packages). Without a key, returns the static bundled infrastructure list. PyPI and npm packages also work with check_package_vulnerability even when absent from this list.
  • check_batch_vulnerabilitiesCheck up to 100 software packages or infrastructure products in a single request. Each item is billed as one API call. Use this instead of multiple check_package_vulnerability calls when you need to audit a lockfile, manifest, or dependency list. Items outside Attestd coverage return outsideCoverage=true and should be treated as unknown risk, not safe. A 429 is returned before any results are delivered if the batch would exceed your monthly quota; no calls are billed in that case.
  • get_cve_detailsReturn full details for a single CVE id (CVSS, EPSS, KEV status, affected products). Use when you need context on a specific CVE before recommending a patch or explaining risk to a developer.

MCP Tenant Isolation tools 4

  • scan_tenant_isolationScan a project path. Returns structured findings with completeness, coverage, concern families, and receipt.
  • list_tenant_isolation_rulesReturns all 57 rules with metadata. Filterable by category.
  • explain_tenant_isolation_ruleReturns rule details, OWASP mapping, CWE IDs, fix suggestions.
  • suppress_tenant_isolation_findingAdd a suppression with reason, approver, controls, and expiry.
