218b0b422d## Summary This PR implements the flattened `_meta` format for server extensions as discussed in #284, replacing the confusing wrapper format with a clean single-file approach. **Before (wrapper format):** ```json { "server": { "name": "my-server", "description": "..." }, "x-publisher": { "build_info": "..." }, "x-io.modelcontextprotocol.registry": { "id": "...", "published_at": "..." } } ``` **After (flattened format):** ```json { "name": "my-server", "description": "...", "_meta": { "publisher": { "build_info": "..." }, "io.modelcontextprotocol.registry": { "id": "...", "published_at": "..." } } } ``` ## Key Changes - **Flattened Format**: Single `ServerJSON` file with structured `_meta` field - **Better DX**: Publishers maintain one file instead of separate server.json + extensions.json - **MCP Compliance**: Uses standard `_meta` mechanism instead of `x-*` prefixes - **Simplified Database**: PostgreSQL now uses simple `id, value` table structure - **Type Safety**: Structured `ServerMeta` with known extension fields ## Database Migration Added migration `003_simplify_to_key_value.sql` that drops the complex relational structure and creates a simple key-value table. This significantly simplifies database management. ## Testing - All core tests passing (validators, service layer) - Schema validation working for all 10 examples - Seed data successfully migrated (396 entries) - Publishing functionality verified Fixes #284
