haiku-version

Version

Call the haiku_version_info tool to retrieve version information.

Display:

• MCP version — the version baked into the running binary at build time (or dev when the binary wasn't built)
• Plugin version — the version from plugin.json on disk
• Build kind — whether the running engine is the compiled production bundle (plugin/bin/haiku.mjs) or a dev process loading TypeScript directly via bun/tsx. The two can disagree with the plugin version if the dev tree has uncommitted or unbuilt changes
• Runtime — node <version> (or bun <version> etc.) — useful when triaging "why does my behavior differ from the docs"
• Entry — the actual file the runtime launched with (process.argv[1]). For prod this points at the bundle; for dev it points at the source file

If a pending update is reported, mention it to the user.

When build_kind is dev, also call out that any working-tree edits to packages/haiku/src/** are live — no rebuild needed. For prod, a rebuild (bun run --cwd packages/haiku build) is required for source edits to take effect.
