This adds a Web Profiler integration for the MCP Bundle that displays MCP server capabilities (tools, prompts, resources, resource templates) in the Symfony debug toolbar and profiler panel. Features: - ProfilingLoader to capture Registry reference during server build - DataCollector to collect and display MCP capabilities - Split templates for each capability type (tools, prompts, resources, resource templates) - Copy Schema button for tool input schemas - Nested tabs structure following Symfony profiler conventions Note: This implementation depends on the loader pattern. If MCP SDK PR symfony#146 (direct Registry injection via DI) is merged, this approach may need adjustment.

There was a problem hiding this comment.
Thanks, this looks great already, but let's please switch to a TraceableRegistry once modelcontextprotocol/php-sdk#150 gets merged - makes sense?
