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	3 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	3 months ago
