A TypeScript MCP server port of Anthropic's filesystem editing tools, allowing file manipulation via client-approved operations without automated writes to prevent system harm.
This is a direct port of Anthropic's filesystem editing tools from their computer use demos to a TypeScript MCP server. It was written largely by Claude Sonnet 3.5 on Roo Cline (now Roo Code) with probably not quite enough direct supervision. I checked over the code and use this server every day, but there may be mistakes or AI weirdness.
I recommend using this server along with mcp-server-commands
Get the files on your computer. Run:
npm install
npm buildIf you're using the Claude desktop app, paste this into your config under "mcpServers", and edit the path to match where you put mcp-editor:
{
"mcpServers":
... your existing servers ...
"mcp-editor": {
"command": "node",
"args": ["/absolute/path/to/mcp-editor/dist/server.js"]
}
}
}If you're using MCP Installer, you just need to provide your LLM with the path on your disk to mcp-editor.
