Rene Cannao 9685cdaa4b mcp discovery: enforce target-scoped run model and add protocol-aware static harvesting (mysql+pgsql) ... Refactor the MCP query/discovery stack to remove prototype-era MySQL-only assumptions and make discovery/catalog semantics explicitly target-scoped. This commit is intentionally not backward compatible with legacy single-target catalog metadata. Key implementation details: - Discovery_Schema: - runs table now stores target_id, protocol, and server_version - resolve_run_id() now requires target_id and resolves schemas within target scope - create_run() now records target/protocol/server version - added legacy schema detection + destructive catalog table rebuild when old runs layout is found - fixed resultset lifetime/escaping issues in target-aware run resolution - New PostgreSQL static harvester: - added PgSQL_Static_Harvester class and build wiring - harvests schemas/objects/columns/indexes/fks/view definitions into Discovery_Schema - maps pg metadata to object_id-based insert APIs used by Discovery_Schema - Query_Tool_Handler: - constructor simplified to catalog_path only (no mcp-mysql_* runtime ctor deps) - discovery.run_static now requires target_id and dispatches protocol-aware harvester at runtime - catalog.*, agent.run_start, and llm.* tool contracts now require target_id when resolving run_id - all run_id resolution call sites switched to resolve_run_id(target_id, ...) - list_schemas catalog query now scoped by target_id via runs join - digest logging path now resolves run_id in target context - ProxySQL_MCP_Server: - updated Query_Tool_Handler construction to new signature - Docs updated: - added explicit target_id scoping guidance for discovery/catalog/agent/llm workflows - clarified protocol-aware routing and noted legacy examples still present in large script docs Build validation: - Recompiled changed objects with PROXYSQLGENAI=1: - Query_Tool_Handler.oo - Discovery_Schema.oo - PgSQL_Static_Harvester.oo - ProxySQL_MCP_Server.oo		3 days ago
