# Claude Code CLI Connect Biosimulant from a terminal on your computer. This guide is separate from the [Claude Code desktop](/agents/connect/claude-code) app guide. ## Open Claude Code first For the **terminal version**, open Terminal on Mac or your terminal app on Windows. Type `claude` and press Enter. If the command is missing, follow [Claude Code’s installation guide](https://code.claude.com/docs/en/setup) first. At the Claude Code prompt, type `/mcp` and press Enter. ## Check for an existing connection In **/mcp**, look for Biosimulant. If Biosimulant is already present, reuse it and authenticate if requested. With a Claude account login, a connector authenticated on [Claude web](/agents/connect/claude) can also be available in Claude Code. API-key and other provider logins do not automatically load Claude account connectors. If a connector is missing, check **/status** for the active login method. ## Add the server directly If no existing connection is available, exit Claude Code and run this in your **terminal**, not as a slash command: ```bash claude mcp add --scope user --transport http biosimulant https://api.biosimulant.com/mcp ``` The explicit **user** scope makes the connection available across projects on this computer. Without it, Claude Code defaults to a local project connection. Run `claude` again. Open **/mcp**, select **biosimulant**, and authenticate. Complete Biosimulant sign-in and approve access in your browser. Start a new Claude Code chat if the tools have not appeared. Using staging? Use the server address from staging Studio in the command above. See [Claude Code’s MCP guide](https://code.claude.com/docs/en/mcp) for scopes and account connector availability. ## Check the connection Ask your agent: ```text Check my Biosimulant account and tell me whether this connection is personal or for a team. Do not start a session or run anything. ``` Confirm the account and context, then [create a session in Studio](/studio/quickstart) and paste its session prompt into this agent. Setup alone does not join a Studio session. [Setup help](/agents/connect/help) · [Choose another app](/agents/connect)
