Monghoul 1.5.7

MCP

• Lazy tool exposure — the MCP server now advertises only ~10 essential tools on connect instead of all 70+, cutting the AI assistant's upfront context cost by roughly 70%. The rest are grouped into categories (charts, themes, sidebar, panels, windows, schema, etc.) and stay hidden until they're needed.
• Three meta-tools always available — discover_tools returns the catalog of hidden tools grouped by category with one-line summaries (no schemas, cheap to call), enable_tools loads tools by category or by name and returns category-specific workflow tips, and disable_tools hides them again to free context. enable_tools({ categories: ['*'] }) loads everything in one call for power users.
• Slimmer server instructions — the MCP welcome blurb dropped chart and workspace cheat-sheets in favor of pointers to the new meta-tools, saving another ~300 tokens. Chart patterns, panel tips, and other category guidance are now returned only when the relevant category is enabled.

Tabs

• No more forever-loading tabs after a crash — if Monghoul was killed or restarted while a query was still running, the affected tab's loading spinner used to be sticky on the next launch; switching to that tab would just spin. The sidecar now sweeps those orphaned execution flags on startup so the tab opens normally and you can re-run the query.
