+Add the server to your user-level `~/.deepagents/.mcp.json` file to make it available in every Deep Agents Code project, or add it to a project-level `.mcp.json` file for only that project. See the [Deep Agents Code MCP tools docs](/oss/deepagents/code/mcp-tools) for discovery locations and precedence rules.

+Then complete the OAuth login flow in one of two ways:
+
+- In the Deep Agents Code TUI, run `/mcp`, select **langsmith**, and follow the login prompt.
+- From your shell, run:
+
+  ```bash
+  dcode mcp login langsmith
+  ```
+
+Launch `dcode`, or restart an active session, to load the LangSmith MCP tools. In an interactive session, run `/mcp` to inspect server status and loaded tools.
