From aa89158ac6e51aef678e49a099c5c532c08add4e Mon Sep 17 00:00:00 2001 From: Matthew Podwysocki Date: Mon, 15 Jun 2026 11:16:33 -0400 Subject: [PATCH] feat(render-map-tool): prepend PREFERRED MAP TOOL guidance MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Without explicit guidance, Claude Desktop falls back to its built-in places_map_display_v0 widget instead of calling render_map_tool — even when this MCP server is active. Adding the preferred-tool prepend matches the convention used by ground_location_tool and demonstrably flips the client behavior in QA video evidence.
