mcp-language-server vs llm-router
mcp-language-server: The MCP Language Server exposes language server capabilities like definition, references, and diagnostics to Large Language Models. It helps MCP-enabled clients navigate codebases more easily by providing semantic tools for code understanding and manipulation.; llm-router: LLM Router is an MCP server and hook set that intercepts prompts and routes them to the cheapest model that can handle the task, saving 60-80% on costs. It works with Claude Code, VS Code, Cursor, and many other AI coding tools, automatically offloading simple tasks to cheaper models while reserving premium models for complex work.
