Smarter automation starts with better data. NodeZero MCP Server plugs exploitability intelligence into your existing AI ecosystem. Now your tools can prioritize, orchestrate, and validate based on attack paths proven to be exploitable, not guesswork.
Overview
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.

Dimensions summary
This listing has one pricing dimension: Free. You pay nothing to use the NodeZero MCP Server. There are no tiers, instance sizes, or usage-based add-ons to select. The single Free dimension applies to all usage. It connects your AI tools to NodeZero exploitability data and lets you launch pentesting operations through natural language queries. Because pricing is flat and free, there is no scaling by volume, users, or capacity.
Top-of-mind questions for buyers
You get the NodeZero MCP Server, which connects your AI tools and language models to NodeZero exploitability data. You can query your asset, vulnerability, and exposure context in plain language. You can also launch and manage pentests directly from your AI client at no charge.
No. Pricing is flat and free, so there is no metering by users, queries, or pentest volume. The vendor-hosted option supports multiple users at no added charge. You will not incur software fees regardless of how heavily your team uses the server.
The vendor-hosted MCP Server runs on the seller's SaaS platform, with infrastructure maintained by the vendor. A locally hosted option exists that you self-host and maintain. The listing itself carries no software charge. Underlying self-hosting resource costs, if any, would fall outside this free dimension.
