mcpls vs fastmcp
mcpls: mcpls bridges AI coding assistants and LSP servers via MCP, providing type information, cross-references, semantic navigation, diagnostics, and safe refactoring. It works with multiple languages and requires minimal configuration.; fastmcp: FastMCP is a standard framework for building Model Context Protocol (MCP) applications, which connect LLMs to tools and data. It simplifies the process by automatically generating schemas, validation, and documentation for tools, and managing transport negotiation and authentication for server connections. FastMCP offers a comprehensive solution for developing, deploying, and scaling MCP-powered systems.
