We’re releasing Slither-MCP, a new tool that augments LLMs with Slither’s unmatched static analysis engine.

Today we’re announcing the beta release of mcp-context-protector, a security wrapper for LLM apps using the Model Context Protocol (MCP). It defends against the line jumping attacks documented earlier in this blog series, such as prompt injection via tool descriptions and ANSI terminal escape codes.

This post describes how many examples of MCP software store long-term API keys for third-party services in plaintext on the local filesystem, often with insecure, world-readable permissions.

This post describes attacks using ANSI terminal code escape sequences to hide malicious instructions to the LLM, leveraging the line jumping vulnerability we discovered in MCP.

Malicious MCP servers can inject trigger phrases into tool descriptions to exfiltrate entire conversation histories and steal sensitive credentials and IP.

MCP’s ’line jumping’ vulnerability lets malicious servers inject prompts through tool descriptions to manipulate AI behavior before tools are ever invoked.
