Pin the curl/wget download to a specific URL with version and verify the downloaded file's SHA-256 checksum before using it. Prefer package manager installs over raw downloads.

Likely FP if the download is from a well-known canonical source (e.g., official GitHub release) and the documentation includes checksum verification steps.

Pin the npx package in the MCP config to an exact version (e.g., @scope/server@1.2.3). Unpinned npx commands can silently fetch a compromised package version.

Likely FP if the MCP config is a local development setup example, though unpinned npx in production configs is a real supply chain risk.
