mcplint

The MCPLint tool itself demonstrates strong security practices in its implementation, such as secure handling of API keys via environment variables or configuration files, robust JSON schema validation, and compartmentalized modules. It functions as a security scanner, interacting with user-specified MCP servers for testing. While this involves executing external commands (via `stdio` transport) or connecting to remote endpoints, these interactions are managed with safety mechanisms like timeouts and resource limits. No `eval` equivalents, direct code injection vulnerabilities, or hardcoded secrets were identified in the Rust source. The fuzzer is designed to intentionally generate potentially malicious inputs, but these are directed at the *target server* under test, not executed within MCPLint's core logic.
