TrojAI | Defend for MCP - Runtime protection for Model Context Protocol deployments.

New tools = new risks.

MCP gives AI agents real autonomy, but with that freedom comes a new class of risk. Each connection, tool, and server introduces another moving part that traditional security tools weren’t built to see or control. Agentic AI-driven systems create and use tools dynamically, opening the door to new attacks.

Shield icon with a crossed-out database symbol, representing blocked or disabled database access.

Unapproved MCP servers

Malicious or unverified servers can expose tools that perform unauthorized actions or leak sensitive data.

Green gear icon with an exclamation mark in the center indicating an alert or warning.

Unapproved tools

Even on trusted servers, unapproved tools can slip past security controls and act outside policy.

Malicious tool descriptions

Attackers can hide prompt injections inside tool metadata — names, descriptions, or parameters that seem harmless but change how an AI model behaves.

Post-approval server and tool integrity

Server or tool metadata changes after approval could signal tampering or a silent “rug pull” attack in which a trusted tool is quietly rewritten to do harm.

Your security command center for MCP.

Identify all MCP servers and tools to stop unauthorized access by malicious actors.

Discover all MCP servers in your environment

Register approved servers to eliminate shadow MCP

Approve MCP tools to prevent rogue or unauthorized tool usage

Confirmation dialog to block TrojAI MCP Server, warning that all traffic will be blocked and approved offerings preserved but inaccessible, with Cancel and Block Server buttons.

Stop rogue MCP servers and prevent manipulation attacks.

Gain full visibility into all MCP traffic to and from each server so you can block unregistered or rogue servers. Eliminate hidden communication paths to protect against common AI attacks like prompt injection, data exfiltration, and more.

Instantly detect server or tool tampering.

Continuously track changes in tool definitions to prevent tampering, drift, or poisoning.

TrojAI MCP Server label with a network icon, server URL, and a pink shield icon indicating the server is blocked.

Automatically block traffic from unapproved tools or MCP servers outside approved paths

Stop prompt injections attacks hidden inside tool descriptions or metadata.

Revoke automated approval if changes to tool descriptions or metadata are detected.

AI policies built to defend MCP workflows.

Protect the enterprise with comprehensive MCP-specific policies that inspect, audit, and enforce security in real time, giving you end-to-end visibility and control.
