313313* MCP servers: threads get their MCP tools from the connectors on your claude.ai account, which are MCP servers you connect once at [claude.ai/customize/connectors](https://claude.ai/customize/connectors) or through the **Manage connectors** link in **Project settings > Environment**. Every thread can use all of them with no per-project setup. The project conversation itself has no connectors, so send work that needs one as a task for a thread. In a project with one repository, threads also load MCP servers from that repository's [`.mcp.json`](/docs/en/cloud-environments#what-carries-over-from-your-setup). [How connectors reach Claude Code](/docs/en/mcp#how-connectors-reach-claude-code) lists the rules for cloud sessions and the settings that turn connectors off.
314314* Command-line tools and packages: install them in the environment's [setup script](/docs/en/cloud-environments#setup-scripts).

316To see which connectors a running thread has at claude.ai/code, open the thread and select **Connectors** from the **+** menu beside its message box. Turning a connector off there removes it from that thread, and it stays off for threads started later until you turn it back on. A thread picks up a connector you add or reconnect after the next message you send it.

Turning a connector off there removes it from that thread and saves that as your account default, so new threads and claude.ai chats start without it until you turn it back on.
