Release summary
This beta continues the work on the Model Context Protocol (MCP) server introduced in the alphas, rounding out the tool set with autonomous build-mode support, log access, UI-error inspection, and lifecycle control (restart / reset). Now the MCP server tool set has all the tools as dev tools window has. The release also fixes reliability issues in the Dev Tools reload state and multi-window handling.
MCP Server
The MCP server gains several new tools and parameters since 1.2.0-alpha02:
| Tool | Description |
|---|---|
await_reload |
Wait for an autonomous reload to complete when the application runs in continuous build mode (--auto), and report the resulting state. |
get_ui_error |
Get the runtime UI exception currently thrown while a window renders (e.g. an exception in a @Composable), with message and (capped) stacktrace. |
get_logs |
Return recent log output from the running application as plain text. |
restart |
Restart the running application with the same arguments and wait for it to reconnect. |
reset_ui |
Discard the current composition so all remember-ed state is dropped and the UI rebuilds from scratch (same as the "Reset UI" dev tools button). |
Additional MCP changes:
de0caf1 — Add a save_to parameter to the take_screenshot tool to write the screenshot to a file.
6bd6a7a — Extend the status response with lastErrorDetails, carrying additional diagnostic lines (such as compiler output) when a reload fails. status also reports uiErrorWindows for windows failing to render.
717b5e0 — Extend the status response with buildContinuous boolean flag indicating whether the app is run in --auto mode.
Dev Tools
6df6e95 — Fix the reload state hanging indefinitely in continuous / auto build mode.
72cc124 — Fix the hot reload panel being non-interactive in multi-window mode.
cf00d0b — Move the "Copy" buttons in the notification overlay to the top line.
