MODEL CONTEXT PROTOCOL (MCP) AND SUPPLY-CHAIN SECURITY

ARTIFICIAL INTELLIGENCE ASSISTANT PROMPTS [START OF PROMPT] Produce a pre-deployment security checklist and apply it to this specific third-party MCP server before we connect our agent to it: [PASTE MCP SERVER NAME/DESCRIPTION/CONFIG/SOURCE IF AVAILABLE HERE]. Cover origin authentication, capability attestation, and known supply-chain red flags. Output format: a checklist with each item marked Pass/Fail/Unknown based on the information given, and a final go/no-go recommendation. [END OF PROMPT] [START OF PROMPT] Run a Static Application Security Testing-style manual review on this server/tool source code and flag any command-injection, path-traversal, or unsafe deserialization vulnerability: [PASTE LAB OR PRODUCTION MCP SERVER / TOOL HANDLER SOURCE CODE HERE]. For each finding, show the vulnerable snippet and the exact fixed version. Output format: a findings table (Line/Function, Vulnerability Type, Fixed Code). [END OF PROMPT] CHAPTER SUMMARY Connecting to third-party MCP servers is a supply-chain decision with real, documented risk. The protocol lacks built-in capability attestation, and registries may be weakly vetted. Origin authentication, version pinning, and separation between servers reduce trust problems. SAST, integrity checks, dependency scanning, and monitoring that links prompts to actions form layered defenses.
