MODEL CONTEXT PROTOCOL (MCP) AND SUPPLY-CHAIN SECURITY

KEEPING AN INVENTORY You cannot protect what you do not know you have. Keep a simple list of every server, package, and external service your harness uses, with its owner, its version, its permissions, and the date it was last reviewed. When a security problem is announced in a popular package, the inventory lets you answer within minutes whether you are affected. Teams without an inventory often spend days searching. READING A REAL WARNING When a security notice about a package or server appears, ask four plain questions. Do we use it, and which version? What can an attacker do with the flaw? Is a fixed version available? What is the quickest safe step, such as updating, disabling, or limiting access, until we can do more? Answering these in order keeps you calm and prevents both panic and neglect. TRUST IS NOT TRANSITIVE A subtle point deserves emphasis. If you trust server A and server A trusts server B, you have not necessarily agreed to trust B. Each new link in a chain adds a party whose care you cannot check directly. Prefer short chains, review each party you depend on, and be ready to remove any link that cannot be vouched for.
