Rene Cannao	b965fc6df4	Fix PROXYSQLGENAI build - resolve circular includes and missing headers ... This commit fixes compilation errors when building with PROXYSQLGENAI=1: Header file fixes: - Add missing #endif /* PROXYSQLGENAI */ before header guards in multiple headers - Remove #include cpp.h from GenAI headers to avoid circular dependencies Source file fixes: - Add #include proxysql.h to GenAI .cpp files that were missing it - Add #include Static_Harvester.h to Query_Tool_Handler.cpp for forward decl Build system fixes: - Remove vec.o from libproxysql.a (it's linked separately in src/Makefile) - Prevents duplicate symbol errors during linking Test files: - Rename MCP test files with .sh suffix to prevent make clean deletion Both build modes now work: - make build_lib_debug (without GenAI) - PROXYSQLGENAI=1 make build_lib_debug (with GenAI)	1 month ago
Rene Cannao	48bc7dd7bf	Merge v4.0 GenAI features into v3.0 with conditional compilation ... This commit merges the experimental v4.0 GenAI/MCP features into the stable v3.0 branch using conditional compilation. All v4.0 features are disabled by default and only enabled when PROXYSQLGENAI=1 is set at compile time. Changes: Build System: - Modified main Makefile to pass PROXYSQLGENAI flag to sub-makefiles - Modified deps/Makefile to conditionally build sqlite-vec and sqlite-rembed - Modified lib/Makefile to add PSQLGA flag and include GenAI object files - Modified src/Makefile to add PSQLGA flag and conditional linking Headers (wrapped with #ifdef PROXYSQLGENAI): - All 20 new GenAI header files in include/ - Modified cpp.h, proxysql_glovars.hpp, proxysql_admin.h - Modified ProxySQL_Admin_Tables_Definitions.h for GenAI/MCP tables Source Files: - All 22 new GenAI source files in lib/ wrapped with #ifdef PROXYSQLGENAI - Modified src/main.cpp for conditional global variables and init/shutdown - Modified Admin_Handler.cpp for conditional command handlers - Modified Admin_Bootstrap.cpp for conditional table registration - Modified Admin_FlushVariables.cpp for conditional variable flushing - Modified ProxySQL_Admin.cpp for conditional admin methods - Modified ProxySQL_Admin_Stats.cpp for conditional MCP stats functions - Modified proxy_sqlite3_symbols.cpp to always compile (needed by core) - Modified MySQL_Session.cpp for conditional GenAI function calls Test Files: - Renamed test_mcp_query_rules-t to test_mcp_query_rules-t.sh - Renamed test_mcp_rag_metrics-t to test_mcp_rag_metrics-t.sh - Modified anomaly_detection-t.cpp for conditional test execution Usage: # Build without GenAI (v3.0 mode - default) make clean && make build_deps -j$(nproc) && make build_lib -j$(nproc) && make build_src -j$(nproc) # Build with GenAI (v4.0 mode) make clean && PROXYSQLGENAI=1 make build_deps -j$(nproc) && PROXYSQLGENAI=1 make build_lib -j$(nproc) && PROXYSQLGENAI=1 make build_src -j$(nproc)	1 month ago
Rene Cannao	7de3f0c510	feat: Add schema separation to MCP catalog and discovery scope constraint ... This commit addresses two issues: 1. MCP Catalog Schema Separation: - Add 'schema' column to catalog table for proper isolation - Update all catalog methods (upsert, get, search, list, remove) to accept schema parameter - Update MCP tool handlers and JSON-RPC parameter parsing - Unique constraint changed from (kind, key) to (schema, kind, key) - FTS table updated to include schema column 2. Discovery Prompt Scope Constraint: - Add explicit SCOPE CONSTRAINT section to multi_agent_discovery_prompt.md - Agents now respect Target Schema and skip list_schemas when specified - Prevents analyzing all schemas when only one is targeted Files modified: - include/MySQL_Catalog.h: Add schema parameter to all catalog methods - include/MySQL_Tool_Handler.h: Update wrapper method signatures - lib/MySQL_Catalog.cpp: Implement schema filtering in all operations - lib/MySQL_Tool_Handler.cpp: Update wrapper implementations - lib/Query_Tool_Handler.cpp: Extract schema from JSON-RPC params, update tool descriptions - scripts/mcp/DiscoveryAgent/ClaudeCode_Headless/prompts/multi_agent_discovery_prompt.md: Add scope constraint	2 months ago
Rene Cannao	221ff23991	Add MySQL exploration MCP tools with SQLite catalog ... Implemented MCP (Model Context Protocol) server providing tools for LLM-based MySQL database exploration: - MySQL_Catalog: SQLite-based catalog for LLM external memory with upsert, get, search, list, merge, delete operations and FTS support - MySQL_Tool_Handler: 17+ database exploration tools with guardrails: * Inventory: list_schemas, list_tables * Structure: describe_table, get_constraints, describe_view * Profiling: table_profile, column_profile * Sampling: sample_rows (max 20), sample_distinct (max 50) * Query: run_sql_readonly (max 200 rows, 2s timeout, SELECT-only) * Relationship: suggest_joins, find_reference_candidates * Catalog: catalog_upsert, catalog_get, catalog_search, catalog_list, catalog_merge, catalog_delete - MCP Module Integration: * Added 6 new configuration variables for MySQL tool handler (mysql_hosts, mysql_ports, mysql_user, mysql_password, mysql_schema, catalog_path) * Added MySQL_Tool_Handler pointer to MCP_Threads_Handler * Implemented tool routing in MCP endpoint for tools/list, tools/describe, and tools/call methods - TAP Tests: Updated to expect 14 MCP variables (was 8) Files: - include/MySQL_Catalog.h, lib/MySQL_Catalog.cpp - include/MySQL_Tool_Handler.h, lib/MySQL_Tool_Handler.cpp - include/MCP_Thread.h, lib/MCP_Thread.cpp - include/MCP_Endpoint.h, lib/MCP_Endpoint.cpp - lib/Makefile, test/tap/tests/mcp_module-t.cpp	2 months ago
