```bash npm install -g @cello-protocol/connect claude mcp add cello -- cello-mcp ``` Then restart Claude Code (or run `/mcp`). ```bash npm install -g @cello-protocol/connect@latest ``` Then restart Claude Code (or run `/mcp`). No `claude mcp remove` / `claude mcp add` required — the binary name `cello-mcp` stays constant across versions.
