About

MCP Security is a focused editorial resource for platform and security teams that operate MCP servers in production. It covers threat modeling, tool-boundary enforcement, prompt injection defense, and the operational controls that keep agent integrations safe.

The content is written for readers who already understand what MCP is and need practical guidance on securing it. That means fewer introductory paragraphs and more direct coverage of attack surfaces, control patterns, and policy architectures.

Every page is curated rather than exhaustive. The goal is to help a team make a decision or understand a risk within a few minutes of landing on the page, not to catalog every tool or technique in the ecosystem.

External references link to primary sources — protocol documentation, published vulnerability disclosures, and reputable security research — wherever possible.
