 This MCP server can be configured to handle requests locally, running as a process and communicating with the MCP client via `stdin` and `stdout`.
-This is the default configuration. The `sse` transport is also configurable so the server is available over the network.
+This is the default configuration, `stdio`. The `streamable-http` and `sse` (deprecated) transports are also configurable, which make the server available over the network.
 Configure the `MCP_TRANSPORT` variable accordingly.
