Bounds-safe string formatting to prevent buffer overflows	1 month ago
Rene Cannao	b3edc6524b	fix: Escape SQL strings in harvest_view_definitions Add escape_sql_string() helper function that doubles single quotes to prevent SQL injection when strings are used in SQL string concatenation. Update harvest_view_definitions to use this function for view_def, schema_name, and view_name. This prevents SQL injection in the UPDATE statement that stores view definitions in the catalog.

Wazir Ahmed	68a41d6db8	MCP: Add handler for prompts and resources Issue ----- - ProxySQL only supports the `tools` feature of the MCP protocol and does not support features such as `prompts` and `resources`. - Although ProxySQL expresses this in its `initialize` response, (server capabilities list contains only the `tools` object), clients such as Warp Terminal ignore it and continue to send requests for methods such `prompts/list` and `resources/list`. - Any response other than `HTTP 200 OK` is treated as an error and client fails to initialize. Fix --- - Handle prompt and resource list requests by returning an empty array. Signed-off-by: Wazir Ahmed <wazir@proxysql.com>	1 month ago

Rene Cannao	7e522aa2c0	feat: Add schema parameter to run_sql_readonly with per-connection tracking Add optional schema parameter to run_sql_readonly tool that allows queries to be executed against a specific schema, independent of the default schema configured in mcp-mysql_schema. Changes: - Added current_schema field to MySQLConnection structure to track the currently selected schema for each connection in the pool - Added find_connection() helper to find connection wrapper by mysql pointer - Added execute_query_with_schema() function that: - Uses mysql_select_db() instead of 'USE schema' SQL statement - Only calls mysql_select_db() if the requested schema differs from the current schema (optimization to avoid unnecessary switches) - Updates current_schema after successful schema switch - Updated run_sql_readonly handler: - Extracts optional 'schema' parameter - Calls execute_query_with_schema() instead of execute_query() - Returns error response when query fails (instead of success) - Updated tool schema to document the new 'schema' parameter This fixes the issue where queries would run against the default schema (configured in mcp-mysql_schema) instead of the schema being queried, causing "Table doesn't exist" errors when the default schema differs from the discovered schema.	1 month ago
Rene Cannao	ee13e4bf13	feat: Add include_objects parameter to llm_search for complete object retrieval Enhance the llm_search MCP tool to return complete question template data and optionally include full object schemas, reducing the need for additional MCP calls when answering questions. Changes: - Added related_objects column to llm_question_templates table - Updated add_question_template() to accept and store related_objects JSON array - Enhanced fts_search_llm() with include_objects parameter: - LEFT JOIN with llm_question_templates to return example_sql, related_objects, template_json, and confidence - When include_objects=true, fetches full object schemas (columns, indexes) for all related objects in a single batch operation - Added error checking for SQL execution failures - Fixed fts_search_llm() get_object() call to pass schema_name and object_name separately instead of combined object_key - Updated Query_Tool_Handler: - Added is_boolean() handling to json_int() helper to properly convert JSON boolean true/false to int 1/0 - Updated llm.search handler to extract and pass include_objects parameter - Updated llm.question_template_add to extract and pass related_objects - Updated tool schemas to document new parameters This change allows agents to get all necessary schema information in a single llm_search call instead of making multiple catalog_get_object calls, significantly reducing MCP call overhead.	1 month ago
Rene Cannao	5668c86809	fix: Implement FTS indexing for LLM artifacts and fix reserved keyword issue - Rename llm_search_log column from \"limit\" to \"lmt\" to avoid SQL reserved keyword - Add FTS inserts to all LLM artifact upsert functions: - add_question_template(): index question templates for search - add_llm_note(): index notes for search - upsert_llm_summary(): index object summaries for search - upsert_llm_domain(): index domains for search - upsert_llm_metric(): index metrics for search - Remove content='' from fts_llm table to store content directly - Add <functional> header for std::hash usage This fixes the bug where llm_search always returned empty results because the FTS index was never populated.	1 month ago

All timing values are in microseconds using monotonic_time(). New schema: - tool VARCHAR - schema VARCHAR - count INT - first_seen INTEGER (microseconds) - last_seen INTEGER (microseconds) - sum_time INTEGER (microseconds - total execution time) - min_time INTEGER (microseconds - minimum execution time) - max_time INTEGER (microseconds - maximum execution time)	1 month ago

Rene Cannao	35b0b224ff	refactor: Remove mcp-catalog_path variable and hardcode catalog path Remove the mcp-catalog_path configuration variable and hardcode the catalog database path to datadir/mcp_catalog.db for stability. Rationale: The catalog database is session state, not user configuration. Runtime swapping of the catalog could cause tables to be missed and the catalog to fail even if it was succeeding a second earlier. Changes: - Removed catalog_path from mcp_thread_variables_names array - Removed mcp_catalog_path from MCP_Thread variables struct - Removed getter/setter logic for catalog_path - Hardcoded catalog path to GloVars.datadir/mcp_catalog.db in: - ProxySQL_MCP_Server.cpp (Query_Tool_Handler initialization) - Admin_FlushVariables.cpp (MySQL_Tool_Handler reinitialization) - Updated VARIABLES.md to document the hardcoded path - Updated configure_mcp.sh to remove catalog_path configuration - Updated MCP README to remove catalog_path references	1 month ago
