MCP Ts Morph MCP Server

If you already use MCP Ts Morph, the mcp ts morph mcp server is the piece that lets your assistant work with it directly. ts-morph を利用した MCP リファクタリングサーバー.

What the server does

このパッケージは GitHub Actions ワークフロー（.github/workflows/release.yml）を介して npm に自動公開されます。

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

• rename_symbol_by_tsmorph — The rename_symbol_by_tsmorph tool exposed by this server
• rename_filesystem_entry_by_tsmorph — The rename_filesystem_entry_by_tsmorph tool exposed by this server
• find_references_by_tsmorph — The find_references_by_tsmorph tool exposed by this server
• remove_path_alias_by_tsmorph — The remove_path_alias_by_tsmorph tool exposed by this server
• move_symbol_to_file_by_tsmorph — The move_symbol_to_file_by_tsmorph tool exposed by this server
• change_signature_by_tsmorph — The change_signature_by_tsmorph tool exposed by this server
• get_type_at_position_by_tsmorph — The get_type_at_position_by_tsmorph tool exposed by this server
• find_unused_exports_by_tsmorph — The find_unused_exports_by_tsmorph tool exposed by this server

Credentials and setup notes

Configuration is passed through the environment: LOG_LEVEL, LOG_OUTPUT, LOG_FILE_PATH. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

Installation

The server ships on npm as pnpm, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.

Where it fits

This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. MCP Ts Morph's toolset — rename_symbol_by_tsmorph, rename_filesystem_entry_by_tsmorph, find_references_by_tsmorph and 5 more — is a fair guide to whether it matches your workflow. It is maintained by SiroSuzume; worth a glance at recent repository activity before you build anything load-bearing on it.

Worth knowing first

• It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
• Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.
