Astrix’s MCP Discovery 

As organizations embrace MCP, visibility and security are critical. Astrix helps you discover MCP servers across your environment, manage risks, and stay compliant while adopting the latest AI technologies.

The MCP Security Challenge

The Model Context Protocol (MCP) is fast becoming the standard for connecting AI agents to enterprise systems. However, rapid adoption often comes with hidden risks:

The expanding attack surface

The State of MCP Server Security 2025 research reveals that while 88% of MCP servers require credentials, more than half (53%) still rely on static API keys or Personal Access Tokens (PATs), which are long-lived credentials that require continuous rotation to remain secure. Only 8.5% use OAuth, the preferred delegation framework, while 79% of API keys were found to be passed via simple environment variables. This pattern reflects a wider security issue highlighted in the latest Verizon Data Breach Investigations Report (DBIR), which identifies credential exposure as a leading cause of account compromise.

MCP-related attacks

Malicious MCP servers have already been identified in the wild, designed to exfiltrate information without detection. Even official MCP implementations have shown vulnerabilities that could be weaponized by threat actors. For example, a counterfeit “Postmark MCP Server” discovered in early 2025 silently BCC’d all processed emails, including internal documents, invoices, and credentials, to an attacker-controlled domain. Distributed under the same name as the legitimate Postmark integration, it successfully infiltrated production environments by exploiting the trust developers place in MCP servers, demonstrating how easily a poisoned or impersonated implementation can leak sensitive data through normal agent operations.

The Result: Security teams are facing a growing visibility gap in AI ecosystems, where unmanaged MCP servers become blind spots and identity risks.

The Solution: Astrix MCP Discovery

Astrix MCP Discovery provides complete visibility and control over how MCP servers are deployed, accessed, and used across your organization. It continuously identifies every connection, classifies each server, and uncovers credential usage, permissions, and potential threats – enabling teams to secure AI adoption without friction.

MCP Discovery enables you to:

• Identify who is using MCP servers and who owns them
• See which AI agents (e.g., Cursor, Claude Code, WindSurf) are connected
• Determine if servers are local or remote, Official or unofficial
• Understand what platforms and permissions are being used
• Detect inactive or orphaned MCP servers
• Assess how authentication occurs (OAuth, API Keys, long-lived tokens)
• Detect exposed secrets on endpoints – Potentially transform those secrets into vaulted secrets

Key Benefits

• Comprehensive visibility across all MCP activity
• Fast time-to-value with low-touch deployment
• Seamless integration with SentinelOne, Microsoft Defender, and CrowdStrike
• Actionable insights to prioritize and remediate risks

How Astrix MCP Discovery Works

To deliver full MCP visibility, Astrix leverages endpoint intelligence and telemetry already available across the organization. This is achieved through two complementary deployment methods, ensuring flexibility and minimal overhead.

1. EDR Integration

Astrix integrates directly with your existing EDR platforms. including SentinelOne, Microsoft Defender for Endpoint, and CrowdStrike, to analyze data collected from endpoints.
This approach provides instant visibility with virtually zero additional setup.

Two support levels are available:

• Basic Discovery A low-touch observability layer that uses existing EDR telemetry to detect MCP activity across the organization. It provides rapid, high-level visibility into AI agent and MCP usage patterns, offering an immediate security baseline with minimal deployment effort. Ideal for organizations seeking quick time-to-value and a foundation for deeper analysis.
  
• Advanced Visibility A comprehensive discovery tier that combines EDR event data with file collection and on-endpoint logic execution to achieve deep inspection of MCP context.

2. Endpoint Service
Astrix integrates seamlessly with leading policy enforcement and device management solutions to deploy a lightweight endpoint service that automatically collects MCP-related data. The service can be easily distributed through tools such as Microsoft Intune and Jamf, requiring no manual intervention. This approach delivers complete, continuous visibility into MCP usage across all devices.
