Implements MCP server icons at the correct architectural level (server initialization) instead of at the tool level. Adds both light and dark theme variants of the Mapbox logo using base64-encoded SVG data URIs. - Add mapbox-logo-black.svg for light theme backgrounds - Add mapbox-logo-white.svg for dark theme backgrounds - Update server initialization to include icons array with theme property - Use 800x180 SVG logos embedded as base64 data URIs This replaces the previous incorrect approach of adding icons to individual tools, which was not aligned with the MCP specification.

Updates the MCP SDK from 1.25.1 to 1.25.2 and recreates the output validation patch for the new version. The patch continues to convert strict output schema validation errors to warnings, allowing tools to gracefully handle schema mismatches. Changes: - Update @modelcontextprotocol/sdk from ^1.25.1 to ^1.25.2 - Recreate SDK patch for version 1.25.2 - Remove obsolete 1.25.1 patch file - All 397 tests pass with new SDK version Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Implement the MCP Apps pattern for static_map_image_tool, maintaining backward compatibility by supporting both patterns simultaneously. Changes: - Add _meta.ui.resourceUri to static_map_image_tool response for MCP Apps pattern - Create StaticMapUIResource (ui:// scheme) for static map previews - Register StaticMapUIResource in resourceRegistry.ts The MCP Apps pattern enables broader client compatibility (Claude Code, VS Code) while preserving existing MCP-UI functionality. The tool now returns both: 1. MCP-UI resource content via createUIResource() 2. MCP Apps metadata via _meta.ui.resourceUri This graceful degradation allows clients to use whichever pattern they support. Related: https://blog.modelcontextprotocol.io/posts/2026-01-26-mcp-apps/ All tests passing (582 tests).

Closing this PR - MCP Apps support doesn't make sense for static_map_image_tool since it returns an image (base64 data), not a URL. The tool already includes the image in the response and MCP-UI handles iframe display. MCP Apps is better suited for tools that return URLs as primary content (like the devkit tools: preview_style_tool, style_comparison_tool, geojson_preview_tool). Focusing on mcp-devkit-server PR #62 for MCP Apps support instead. |

This PR implements MCP Apps support for static_map_image_tool, enabling interactive map preview in compatible hosts (VS Code, Claude Code, Goose). ## Changes - Add @modelcontextprotocol/ext-apps dependency and upgrade SDK to 1.25.3 - Add meta property to BaseTool for MCP Apps metadata (_meta.ui) - Create StaticMapUIResource serving interactive HTML with MCP Apps SDK - Refactor StaticMapImageTool to return URL instead of base64 image - Update index.ts to register UI resources with registerAppResource - Update all tests to expect URL text content instead of image data ## Benefits - No server-side image fetching (URL-based approach) - Interactive visualization in MCP Apps-capable hosts - CSP configuration for api.mapbox.com domains - Maintains backward compatibility with MCP-UI pattern - Consistent with mcp-devkit-server implementation ## Testing All 597 tests passing ✅ ## Related - Companion to mcp-devkit-server PR #62 - Resolves closed PR #107 properly Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
