secrets-mcp-server

The server utilizes native operating system secret management APIs (Windows Credential Vault/DPAPI, macOS Keychain, Linux Secret Service) via the `@napi-rs/keyring` library, which is a strong security practice as it leverages OS-level encryption and access controls. Communication is restricted to standard I/O (stdin/stdout) using the Model Context Protocol, eliminating direct network exposure for the server itself. Input validation for all tool parameters is performed using Zod schemas, reducing the risk of malformed inputs or injection attacks. No 'eval', code obfuscation, or hardcoded sensitive credentials were found in the application logic. The primary security risk would lie in potential vulnerabilities within the underlying native OS keyring implementations or the `@napi-rs/keyring` bindings, which are external dependencies.
