A lightweight Model Context Protocol (MCP) server for TypeScript and JavaScript refactoring. Every tool maps directly to a tsserver protocol command — the output is the raw, unmodified response from TypeScript's compiler. Rename symbols, extract functions, move declarations between files, reorganize imports, get diagnostics, find references, and more — with every import, require, re-export, and reference updated automatically across your entire codebase.

AI coding assistants can read and write code, but they struggle with structural changes that ripple across many files. Renaming a function, extracting a helper, moving a React component, or reorganizing a folder means updating every reference and import that touches it. Miss one and the build breaks.

ts-mcp-server gives any MCP-compatible client — VS Code Copilot, Claude Desktop, Cursor, Windsurf, Continue, and others — the ability to perform these refactors correctly and completely, using TypeScript's own compiler infrastructure.

• 12 tools — each a 1:1 mapping to a native tsserver protocol command
• Rename symbols — variables, functions, classes, types, properties, interfaces, enums — all references updated across every file
• Extract function — extract a code range into a new function with auto-detected parameters and return type
• Extract constant — extract an expression into a named constant with inferred type
• Extract type — extract an inline type annotation into a named type alias
