v1.2.5

What's New

New Features

• Screenshot double-size option — The screenshot command now supports a doublesize option for higher resolution captures.
• Key combo support — New emu_keyboard.sendKeyCombo command allows sending keyboard combinations (e.g. CTRL+STOP) to the openMSX emulator.
• Interactive machine & extension resolution — The launch command now uses user elicitation to interactively resolve machine type and extensions when not explicitly specified.
• Structured Content responses — All tools now return structured content responses, improving compatibility with MCP clients that consume typed output.
• Cancellable sleep with AbortSignal — Internal async operations now support cancellation via AbortSignal, improving responsiveness when tools are interrupted.

Improvements

• Tool & resource annotations — Tools and resources now include MCP annotations (audience, priority, readOnlyHint, destructiveHint, idempotentHint, openWorldHint) for better client-side metadata handling.
• Modular sampling — samplingFindMatches has been extracted into its own module (server_sampling.ts) for better code organization and reusability.
• MCP SDK upgrade — Updated to MCP SDK >1.26.0 with improved dependency management.
• Agent Skill — Added a comprehensive mcp-openmsx-usage agent skill to guide AI agents in using all available tools and resources.
