Horizon3.ai Introduces MCP Server to Accelerate Remediation and Close the Find–Fix–Verify Loop

SAN FRANCISCO--(BUSINESS WIRE)--Horizon3.ai, the leading provider of offensive security solutions, today officially announced the availability of its Model Context Protocol (MCP) Server, a capability designed to help security teams close the gap between finding vulnerabilities and fixing them. By transforming pentest results into automated remediation workflows, MCP Server enables organizations to reduce risk faster, more measurably, and with less manual effort.

“The hard part is no longer finding vulnerabilities — it’s fixing them,” said Snehal Antani, CEO and Co-founder of Horizon3.ai. “Security teams are buried under backlogs and tool sprawl. MCP Server cuts through the noise by turning NodeZero pentest findings into actions: roll credentials, tune defenses, open tickets, and re-test fixes in minutes instead of weeks.”

Outcomes That Matter

  • Remediation at Scale: MCP Server streamlines the fix cycle, enabling security teams to remediate across thousands of systems without the bottlenecks of manual coordination.
  • Faster Risk Reduction: Automated workflows shrink the time between detection and resolution, reducing exposure windows that attackers exploit.
  • Seamless Integration: MCP Server connects with ticketing systems, SIEMs, and security tools, eliminating the need to glue together workflows across fragmented platforms.
  • Proof of Fix: Every remediation can be immediately re-tested and verified by NodeZero, giving CISOs defensible evidence that issues are resolved.

“MCP Server exposes our 10,000 GQL API data points to both humans and agents, enabling them to interface with NodeZero® quickly and effectively to build workflows,” added Snehal.

Closing the Loop

With MCP Server, Horizon3.ai operationalizes the find–fix–verify loop that security leaders have long sought. Pentest results are no longer static reports, but actionable inputs that drive measurable outcomes. The result: security programs that not only discover risk, but continuously reduce it.

Availability

The MCP Server is available today as part of the NodeZero® Offensive Security Platform.
