read_file
Read a file, or a line range of one, without downloading it
How to use it
read_file is exposed by the Claude Design MCP MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), and the read_file tool becomes available to the model automatically. See the full listing for setup details and every tool this server provides.
