Episode notes
MCP Created A New Attack Surface
- Model Context Protocol (MCP) standardizes how LLMs connect to external tools and data sources, replacing ad-hoc tool calls with a toolkit model.
- Its rapid adoption created a sprawling new attack surface that security teams now must manage.
Community MCP Servers Proliferated
- Community-built MCP servers proliferated quickly after Anthropic published examples, despite uneven security.
- Rahul warned this led to people grabbing servers that talk to sensitive SQL databases without proper controls.
Authentication Gaps Are Widespread
- Early MCP specs omitted authentication, creating many unauthenticated servers on the internet.
- Even after adding auth, inconsistent implementations left enterprises exposed.
