building-mcp-server-on-cloudflare

This skill/documentation describes legitimate functionality for building MCP servers on Cloudflare Workers and mostly aligns with its stated purpose. It is not obviously malicious, but there are meaningful security risks: examples allow execution of raw SQL from client-supplied strings, provide a public/no-auth template that would expose powerful bindings, and permit outbound network calls constructed from parameters. These patterns create high potential for data exposure, SQL injection, SSRF, and credential misuse if used as-is. Recommend: remove examples that execute raw SQL from untrusted input, require/encourage authenticated deployments by default, validate or parameterize DB queries, restrict outbound requests or validate destination domains, and document secure handling of OAuth secrets and least-privilege bindings.
