- Example of tool description manipulation leading to unauthorized data access (e.g., API and SSH keys).
- Tool Poisoning Attacks:
- Attackers can embed malicious instructions in tool descriptions invisible to users.
- Explains the concept of shadowing tool descriptions across multiple servers.
- Mitigation Strategies:
- Ensure tool descriptions are visible to users.
- Implement tool version pinning and hashing to prevent unauthorized changes.
- Maintain strict boundaries and data controls between multiple MCP servers.
- Best Practices:
- Vet every MCP server and tool for security.
- Ensure that any downloaded cursor rules are properly vetted.
