MCP is in development

Server behavior and tool contracts may change. Tool availability depends on the server configuration.

* **get_server_info**( [socket_name](https://libtmux.org/en/py/stable/mcp/tools/get_server_info/#mcp.tool.get_server_info.input%2Fproperties%2Fsocket_name)?: [string](https://json-schema.org/understanding-json-schema/reference/string "string (JSON Schema)") | [null](https://json-schema.org/understanding-json-schema/reference/null "null (JSON Schema)"), )

  Get information about the tmux server.

  Use to verify the tmux server is running before other operations. For session-level details, use [list_sessions](https://libtmux.org/en/py/stable/mcp/tools/list_sessions/) instead.

  * MCP request method

    `tools/call` Send `get_server_info` as the tool name, with the arguments below.

  ## Arguments[#](https://libtmux.org/en/py/stable/mcp/tools/get_server_info/#mcp.tool.get_server_info.parameters)
