Detects patterns that check for tool existence and install if missing
If `get_started` is NOT available**, the MCP server needs to be installed. **Ask the user for confirmation before proceeding** — explain that this will download Replace conditional download-and-install logic with explicit dependency declarations in a manifest file (package.json, requirements.txt). Verify checksums for any runtime downloads.
Likely FP if the conditional install is documentation showing standard prerequisite checks (e.g., checking if a tool is installed before installing it).
Detects automatic registration of MCP servers into agent configuration
claude mcp add 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.
Detects MCP server configs using npx to run packages without version pinning
"command": "npx" 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.
Detects -y, --yes, or --auto-approve flags in MCP/skill install commands that bypass user confirmation
"-y" Remove the -y/--yes auto-confirm flag from MCP server launch arguments. This flag bypasses user confirmation prompts and allows unattended execution of potentially dangerous operations.
Likely FP if the matched text is an isolated flag (-y or --yes) in documentation describing command-line options, not in an actual MCP config.
Detects npx with -y flag that bypasses user confirmation for package installation
npx -y Replace npx -y with an explicit npm install step that pins the package to a specific version, then run it. Remove the -y flag to require user confirmation.
Likely FP if the npx command runs a well-known, trusted tool (e.g., create-react-app) in documentation context with no version pinning concern.
Detects -y, --yes, or --auto-approve flags in MCP/skill install commands that bypass user confirmation
add --transport stdio leetcode -- npx -y Remove the -y/--yes auto-confirm flag from MCP server launch arguments. This flag bypasses user confirmation prompts and allows unattended execution of potentially dangerous operations.
Likely FP if the matched text is an isolated flag (-y or --yes) in documentation describing command-line options, not in an actual MCP config.
