Claude Code CLI

1. Open a terminal.

2. Run:

claude mcp add --scope user --transport http spreadjs-mcp https://developer.mescius.com/mcp/spreadjs --header "Authorization: Bearer <YOUR_MCP_TOKEN>"

This example uses --scope user, which makes the MCP server available across your Claude Code projects. Use --scope local only if you want the server to apply to the current project.

3. Verify the configuration:

claude mcp list 
claude mcp get spreadjs-mcp
