ContrastAPI — 55 Security Tools + 7 MCP Resources for AI Agents

Security intelligence, built for AI agents. Give your agent grounded answers about vulnerabilities, threats, and attack surface — backed by authoritative sources (NVD, CISA KEV, FIRST EPSS, MITRE ATLAS & D3FEND), never guesswork. CVE/KEV/CWE lookup with EPSS exploit-probability and composite risk scoring, domain & IP investigation, IOC enrichment, code-security checks, and live web intelligence. 55 tools, 7 Resources, and 3 Prompts — free, no API key, no signup.

API Documentation — REST reference: 60+ endpoints, authentication, rate limits, token costs, and response envelope.
MCP Documentation — MCP tool-selection guide, 7 Resources, 3 Prompts, and copy-paste agent prompts.

Setup (MCP)

Any MCP client

{
  "mcpServers": {
    "contrastapi": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://api.contrastcyber.com/mcp/"]
    }
  }
}

Restart your agent. Other clients (Python SDK, Node SDK, cURL, VS Code): mcp-setup · quickstart

Claude Desktop — one-click extension

Grab the .mcpb file from the latest release and double-click it (or Claude Desktop → Settings → Extensions → Install Extension…). No signup, no API key — all 55 tools ready immediately.

SDKs

pip install contrastapi      # Python 3.10+ — sync + async, typed responses, shortcut helpers
npm install contrastapi      # Node 14+ — concrete TypeScript types, 14 namespaces

Both SDKs cover every HTTP endpoint and MCP tool — CVE/KEV/CWE, ATLAS, D3FEND, Sigma rules, email security posture, domain, IP, IOC, code security, and web intelligence — with wire-exact response shapes and a typed exception hierarchy that mirrors the API error envelope. They also expose MCP Resources for browsing the ATLAS, D3FEND, and CWE catalogs (see docs/MCP_Documentation.md) and a conditional triage Prompt (see docs/MCP_Documentation.md#contrast-triage). Web-intelligence tools — robots_txt, redirect_chain, email_verify, brand_assets, seo_audit, geo_audit — ship with an explicit ethical floor: per-target throttling, robots.txt respected, no SMTP probing.

Responses include a verdict block — deterministic, falsifiable_fields, data_age_seconds, sources_queried / sources_unavailable, completeness — so a verifier agent can independently re-derive specific fields from the upstream authority (NVD, RDAP, CT logs, URLhaus). Probe GET /v1/capabilities for "verdict_metadata": true.

CVE responses also embed next_calls: list[PivotHint] — {tool, input, reason} triples that suggest the next MCP tool to call (e.g. kev_detail when kev.in_kev=true, cwe_lookup when cwe_id is set). Agents chain workflows without manual prompting.
