Summary from the TLDR InfoSec newsletter

`mcp-context-protector` is a security wrapper for LLM apps using MCP that defends against line jumping attacks and prompt injection via tool descriptions and ANSI escape codes. It requires users to review new and modified server descriptions and tool definitions. The tool sanitizes ANSI sequences to prevent prompt injection and is implemented as an MCP. It is unable to evaluate chain-of-thought attacks.
