What
/mcp opens a list of your MCP servers, which are outside programs that give Claude extra tools. Each server has a list of its tools. Tools your organization has blocked used to be greyed-out rows you could not move onto, labelled "disabled by your organization".
- A blocked tool can now be highlighted like any other row.
- Selecting it changes the line under the list to " is disabled by your organization" in warning colour, instead of opening the tool.
- The hint for pressing Enter is hidden while a blocked tool is highlighted.
- For a tool marked ask-only, that fact now comes first in its row.
Why
In workplaces where an administrator controls which tools are allowed, you can now move onto a blocked tool and read plainly that it is blocked on purpose.

The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.
Confirmed since
Anthropic's documentation has since written up /mcp, on Hooks reference.
* **[MCP tool hooks](#mcp-tool-hook-fields)** (`type: "mcp_tool"`): call a tool on a configured [MCP server](/docs/en/mcp). The tool's text output is treated like command-hook stdout.hooks see the edit
