Overview

Product video
The NodeZero MCP Server requires an active NodeZero Platform subscription; please review the documentation for deployment instructions specific to your portal region (US or EU). While the MCP Server is available for no additional cost, it unlocks the full value of your existing NodeZero investment by enabling the platform to integrate naturally within agentic AI and automation workflows.
Your AI orchestration can query NodeZero findings, launch targeted tests, and act on facts instead of severity scores - all without human intervention. No manual exports, no hand-triggered tests, just continuous validation powered by your own exploit data. Because it's powered by natural language, anyone on your team can interact with NodeZero's intelligence without needing to master the platform or its APIs.
You chose NodeZero because it proves what's actually exploitable in your environmen - not just what could be vulnerable. The MCP Server brings that same exploitability intelligence directly to your AI investments, making validated attack paths, credential exposures, lateral movement opportunities, and business asset impact programmatically accessible to your entire AI stack. This is the data layer that transforms your AI tools from generic CVE processors into risk-aware systems that prioritize what truly matters to your organization.
Highlights
- MCP Server understands how attackers break into your business, runs real pentests and drives remediation workflows in one motion, shrinking MTTR from weeks to hours by augmenting your existing team with a supertool.
- This isn't just prioritization - it's automated action, driven by adversarial proof, embedded in every step of your security workflow.
- As more tools adopt MCP, your LLM's reach grows - giving you a plug-and-play ecosystem to automate and scale security without complexity.
