You Cannot Defend an MCP Server You Do Not Know You Are Running
Tool poisoning is the most impactful client-side MCP vulnerability, and the defensive research is solid. All of it assumes you know which MCP servers you connect to. Almost nobody does.
How tool poisoning attacks compromise MCP tool descriptions
A single poisoned tool description can turn a trusted MCP server into a silent data-exfiltration channel. Here's how these attacks work — and how to stop them.
Risks of MCP server rug-pulls and silently changing tool ...
An MCP rug pull attack swaps a trusted server's tool definitions after approval. Here's how tool definition drift happens, and how Safeguard catches it early.
MCP server security for AI coding agents
A critical RCE in Anthropic's own MCP Inspector (CVSS 9.4) and two Cursor CVEs show that giving AI agents tool access creates a new, largely unvetted attack surface.
Securing Model Context Protocol (MCP) servers
MCP server security explained through real 2025 CVEs, tool poisoning, and rug-pull attacks, plus concrete controls security teams need to defend AI agent tool calls.
mcp-scan: detecting malicious MCP tool definitions
MCP lets AI agents call tools via plain-text descriptions the model trusts blindly. Here's how mcp-scan catches poisoning, rug-pulls, and shadowing.
Securing MCP server registries: risks of unvetted AI tool...
Unvetted MCP servers already power tool poisoning and rug-pull attacks. Here's why package scanning like JFrog's isn't enough, and how to actually secure your MCP registry.
Cursor MCP Security: The Risks and How to Harden It
Cursor's MCP support lets the AI editor call external tools and data sources. That power comes with real risks. Here is how Cursor MCP can be attacked and hardened.
Tool Poisoning Attacks: How Malicious Instructions Hide I...
AI agent tools can hide invisible instructions attackers use to steal data. Here's how tool poisoning attacks work and how Safeguard stops them.
Model Context Protocol Security 101: What Could Go Wrong ...
MCP lets AI models call tools automatically — and lets malicious servers hide instructions in plain sight. Here's how tool poisoning, rug pulls, and shadowing actually work.
Agentic AI Security Glossary: Tool Poisoning, Prompt Inje...
A precise glossary of agentic AI security terms — prompt injection, tool poisoning, model jailbreaking, excessive agency, and MCP rug pulls — with concrete attack examples.
MCP tool poisoning: hidden instructions and rug-pulled tool definitions
Tool-poisoning attacks against Model Context Protocol servers hide adversarial instructions inside tool descriptions and silently mutate tool definitions after install. Here is how the attack works and how to defend against it.
Self-healing security runs on Safeguard.
