Overview
A Go library for building Model Context Protocol (MCP) servers with a fluent API, especially for integrating with Large Language Models (LLMs) to provide and execute tools efficiently.

Security Notes
The library adheres to good Go practices, utilizing standard networking and JSON handling with internal error handling for invalid requests/parameters. Key security features include default `InsecureSkipVerify: false` for TLS, and `MAX_TOOL_CALL_ITERATIONS` to prevent infinite tool loops in LLM integration. Potential risks typically stem from user-implemented tool handlers (e.g., unsafe file I/O or OS command execution without validation) rather than the core library itself. While tool search could be a DoS vector for very long inputs if not protected by an upstream API gateway, the internal implementation does not show immediate vulnerabilities.
