cisa-kev-mcp

Search CISA's Known Exploited Vulnerabilities catalog. This is a focused companion to vulnerability scanners: it helps an agent identify vulnerabilities that CISA has marked as exploited in the wild.

Tools

• search_known_exploited: search CVE, vendor, product, vulnerability name, and description fields.

• recent_known_exploited: list recently added catalog entries.

• catalog_info: inspect catalog version, release date, and entry count.

• by_cve

• by_vendor

• by_product

• ransomware

• vendors

• yearly The feed is public and keyless. Catalog inclusion is a prioritization signal, not a complete risk assessment or a guarantee that a system is vulnerable.

Run

npm install
npm run build
node dist/index.js

Quick start

npm install
npm run build
node dist/index.js

The server uses stdio, so it can be connected to Claude Desktop, Cursor, VS Code, MCP Inspector, or another compatible MCP client.

Tools at a glance

• search_known_exploited: Search CISA
• recent_known_exploited: List the most recently added entries in the CISA KEV catalog.
• catalog_info: Get CISA KEV catalog version and release metadata.

Limits and privacy

This project is intentionally narrow. It should be treated as a practical helper, not a complete certification or security audit. Check the implementation and the returned data before using it with sensitive material. No credentials are required unless the project explicitly says otherwise.

Try it

After building, connect the server through your MCP client. The repository root also contains smoke-test.mjs for projects covered by the shared harness. A typical tool call starts with search_known_exploited.
