Runnable MCP agent attacks – DNS rebinding, rug pull, and mitigations

AI Analysis
●●SolidWizardryNiche Gem
DNS rebinding on MCP is clever, but mitigations require their specific SDK.
Strengths
- •Concrete DNS rebinding proof-of-concept specifically targeting MCP transport layers.
- •Cryptographic sealing of tool definitions prevents mid-session schema tampering effectively.
- •Local SQLite seeding makes the rug pull scenario deterministic and reproducible.
Weaknesses
- •Mitigations tightly coupled to their specific SDK rather than protocol-level fixes.
- •Limited to Python 3.13, excluding other common MCP client implementations.
