Assessing the Attack Surface of Remote MCP Servers

This edition dives into our latest analysis of remote MCP servers and how integrations expand the attack surface for LLM-based systems. We also share quick updates from our recent K-Talks session, industry events, and why feedback plays a key role in delivering stronger pentesting assessments.

šŸ“ Latest from Our Blog:

MCP (Model Context Protocol) defines how LLMs interact with external data sources and tools. However, more reach and integrations equals more surface, where the usual vulnerability categories show up.

Matias Forti explores how MCP’s architecture impacts pentesting workflows, why conventional tools struggle to keep up, and how frameworks like MCP Inspector and NCC’s HTTP Bridge can help overcome these challenges.

⭐ Highlight:

ā€œWhile the MCP specification brings a novel interface for integrating LLMs with external systems, it also introduces familiar risks in a new format. Remote MCP servers present a clear attack surface that mirrors traditional web application vulnerabilities like command injection, SSRF, and IDOR.ā€
