Non-localhost remote MCP server URL MCPCFG_004

mcp-config L5

Detects MCP server configurations connecting to non-localhost remote URLs

"url":"https://github.com/joelkuijper/trein/releases/latest/download/trein-darwin-arm64"

FIX

Change the MCP server URL to localhost or a trusted internal endpoint. If a remote server is required, verify the domain ownership and use HTTPS with certificate validation.

FP?

Likely FP if the URL points to example.com, a documentation domain, or a well-known SaaS API endpoint (e.g., api.openai.com).

LOW

Runtime URL controlling behavior THIRDPARTY_001

third-party-content L19

Detects URLs fetched at runtime that control or influence agent behavior without pinning

download a standalone binary from [GitHub Releases](https:// + config

FIX

Avoid loading configuration or behavior-controlling content from runtime URLs. Bundle required configurations locally or pin remote config to versioned, integrity-verified endpoints.

FP?

Likely FP if the URL in the match is a documentation link or example URL (e.g., example.com) rather than an actual runtime-fetched configuration endpoint.
