Rene Cannao	23e5efca5a	Test: Don't redirect sys.stderr, write logs directly to file The sys.stderr redirection may be interfering with stdout/stdin pipes. Now logging writes directly to a file handle instead of through sys.stderr.	3 months ago
Rene Cannao	f4a4af8d82	Fix: Write directly to stdout.buffer to bypass TextIOWrapper issues The TextIOWrapper may have buffering issues when stderr is redirected. Writing directly to the binary buffer with encoded bytes ensures immediate delivery of responses to Claude Code.	3 months ago
Rene Cannao	ad54f92dc5	Revert: Simplify tool handlers back to original pass-through Remove all the unwrapping and TextContent wrapping logic that was added. Go back to the original simple pass-through that just returns the result from ProxySQL directly. The original format was correct.	3 months ago
Rene Cannao	2b5134632c	Fix: Wrap tool results in TextContent format for MCP protocol compliance The MCP protocol requires tool call results to be wrapped in content items with type and text fields. This matches what other MCP servers do. Before: {"result": [{"name": "testdb", ...}]} After: {"result": [{"type": "text", "text": "[{\"name\": \"testdb\", ...}]"}]} This should fix the issue where Claude Code was timing out waiting for responses.	3 months ago
Rene Cannao	55dd5ba574	Debug: Add detailed stdout write logging to troubleshoot Claude Code timeout - Revert the stdout replacement changes (was probably not the issue) - Add detailed logging to _writeline to see exactly what's happening when writing to stdout	3 months ago
Rene Cannao	f5606986ff	Fix: Replace stdout with truly unbuffered wrapper to prevent response buffering The previous sys.stdout.reconfigure(line_buffering=True) didn't work when stderr is redirected. Now we create a new io.TextIOWrapper around sys.stdout.buffer with line_buffering=False, ensuring immediate flush. Also sets PYTHONUNBUFFERED=1 for extra safety.	3 months ago
Rene Cannao	edac8eb5e0	Fix: Add verbose logging and fix stdout buffering issue in MCP stdio bridge - Redirect stderr to /tmp/proxysql_mcp_bridge.log for debugging - Add extreme verbosity with timestamps for all stdin/stdout/HTTP traffic - CRITICAL FIX: Set stdout to line-buffered mode to prevent responses from being buffered and never reaching Claude Code (causing timeouts) - Log all HTTP requests/responses to ProxySQL MCP server - Log all message handling and unwrapping operations	3 months ago
Rene Cannao	fc6b462be1	Fix: unwrap ProxySQL nested response format ProxySQL MCP wraps tool responses in {"result": {...}, "success": true}. The bridge now unwraps this to return just the actual result to Claude Code. This fixes the LLM error 'The prompt parameter was not received normally' which occurred because the LLM was receiving the malformed nested structure.	3 months ago
Rene Cannao	4491f3ce0b	Add debug logging to MCP bridge for troubleshooting Add PROXYSQL_MCP_DEBUG environment variable to enable verbose logging of all stdio communication and ProxySQL HTTP requests/responses.	3 months ago
Rene Cannao	01c182ccac	Add stdio MCP bridge for Claude Code integration Add a Python stdio-based MCP server that bridges to ProxySQL's HTTPS MCP endpoint, enabling Claude Code to use ProxySQL MCP tools directly. The bridge: - Implements stdio MCP server protocol (for Claude Code) - Acts as MCP client to ProxySQL's HTTPS endpoint - Supports initialize, tools/list, tools/call methods - Handles authentication via Bearer tokens - Configurable via environment variables Usage: - Configure in Claude Code MCP settings - Set PROXYSQL_MCP_ENDPOINT environment variable - Optional: PROXYSQL_MCP_TOKEN for auth	3 months ago
Rene Cannao	9d6a2173bf	Enhance Rich CLI with configurable LLM chat path and better tracing LLM improvements: - Add configurable chat path (LLM_CHAT_PATH or --llm-chat-path) to support non-standard endpoints like Z.ai's /api/coding/paas/v4 - Add optional JSON mode (LLM_JSON_MODE or --llm-json-mode) for models that support native JSON output - Enhanced tracing: log HTTP status and response body snippet on every request - Safer JSON parsing: treat empty content as error with helpful message - Better error messages with diagnostic hints Code cleanup: - Remove intent command (simplify CLI) - Remove user_intent reading and passing - Simplify stopping logic (just run max_iterations) - Clean up formatting and remove unused code	3 months ago
Rene Cannao	f2ca750c05	Add MCP Database Discovery Agent (initial commit) Add a database discovery agent prototype that uses LLMs to explore databases through the MCP Query endpoint. Includes: - Rich CLI (discover_cli.py): Working async CLI with Rich TUI, proper MCP tools/call JSON-RPC method, and full tracing support - FastAPI_deprecated_POC: Early prototype with incorrect MCP protocol, kept for reference only The Rich CLI version implements a multi-expert agent architecture: - Planner: Chooses next tasks based on state - Structural Expert: Analyzes table structure and relationships - Statistical Expert: Profiles tables and columns - Semantic Expert: Infers domain meaning - Query Expert: Validates access patterns	3 months ago
Rene Cannao	ef5b99edbf	Fix MCP tool bugs: NULL value handling and query validation - Fixed NULL value handling in execute_query: use empty string instead of nullptr to avoid "basic_string: construction from null" errors - Fixed validate_readonly_query: corrected substring length check from substr(0,6)!="SELECT " to substr(0,6)!="SELECT" - Fixed test script: added proper variable_name parameter for get_config/set_config tools Query endpoint tools now pass all tests.	3 months ago
Rene Cannao	de33d177be	Fix verbose mode in test_mcp_tools.sh Verbose output was being printed to stdout, contaminating the captured response value and causing tool discovery to fail. Redirect debug output to stderr instead.	3 months ago
Rene Cannao	25cda31f08	Update test_mcp_tools.sh with dynamic tool discovery - Add discover_tools() function that calls tools/list on each endpoint - Store discovered tools in temp file to avoid bash associative array issues - Define all expected tools with test configurations - Only test tools that are discovered via tools/list - Add support for all 5 endpoints: config, query, admin, cache, observe - Add --list-only flag to show discovered tools without testing - Add --endpoint flag to test specific endpoint - Improve help output with endpoint descriptions	3 months ago
Rene Cannao	093511920f	Add environment variable printing to MCP scripts Print environment variables at the start of each script when they are set: - setup_test_db.sh: Shows MYSQL_HOST, MYSQL_PORT, MYSQL_USER, MYSQL_PASSWORD, TEST_DB_NAME - configure_mcp.sh: Shows MYSQL_HOST, MYSQL_PORT, MYSQL_USER, MYSQL_PASSWORD, TEST_DB_NAME, MCP_PORT - test_mcp_tools.sh: Shows MCP_HOST, MCP_PORT This helps users verify that the correct environment variables are being used.	3 months ago
Rene Cannao	7f957088ee	Fix configure_mcp.sh to allow empty MySQL passwords Change MYSQL_PASSWORD from using :- to = for default value. This allows setting an empty password via environment variable: - MYSQL_PASSWORD="" will now use empty password - Previously, empty string was treated as unset, forcing the default	3 months ago
Rene Cannao	49e6ac5bc6	Revert configure_mcp.sh to respect environment variables The script correctly uses ${VAR:-default} syntax, so it already respects environment variables. The issue was with the MCP server not reinitializing when MySQL configuration changes, which is a separate issue.	3 months ago
Rene Cannao	40cff23c3b	Initialize MySQL Tool Handler and fix default MySQL port - Initialize MySQL_Tool_Handler in ProxySQL_MCP_Server constructor with MySQL configuration from MCP variables - Use GloVars.get_SSL_pem_mem() to get SSL certificates correctly - Add MySQL_Tool_Handler cleanup in destructor - Change configure_mcp.sh default MySQL port from 3307 to 3306 - Change configure_mcp.sh default password from test123 to empty - Update help text and examples to match new defaults	3 months ago

Rene Cannao	d17fe1dba8	Fix configure_mcp.sh error handling and endpoint paths - Split exec_admin into exec_admin (shows errors) and exec_admin_silent - Execute each SET command individually to catch specific failures - Add proper error checking and early exit on configuration failures - Fix MCP endpoint test URL from /config to /mcp/config - Update displayed endpoint URLs to include /mcp/ prefix and all 5 endpoints	3 months ago
Rene Cannao	60d4a7378c	Implement automatic MCP server start/stop and add environment variable support - Add automatic MCP HTTPS server start/stop based on mcp-enabled flag - Server starts when mcp-enabled=true and LOAD MCP VARIABLES TO RUNTIME - Server stops when mcp-enabled=false and LOAD MCP VARIABLES TO RUNTIME - Validates SSL certificates before starting - Added to both flush_mcp_variables___database_to_runtime() and flush_mcp_variables___runtime_to_database() functions - Update configure_mcp.sh to respect environment variables - MYSQL_HOST, MYSQL_PORT, MYSQL_USER, MYSQL_PASSWORD - TEST_DB_NAME (mapped to MYSQL_DATABASE) - MCP_PORT - Updated --help documentation with all supported variables	3 months ago
Rene Cannao	28742554b5	Use relative catalog path instead of absolute path - Change mcp-catalog_path default from /var/lib/proxysql/mcp_catalog.db to mcp_catalog.db - SQLite accepts relative paths, which are resolved relative to the process working directory - ProxySQL's working directory is its datadir, so the catalog will be stored there - Update configure_mcp.sh to set mcp-catalog_path='mcp_catalog.db' - Update lib/MCP_Thread.cpp default to "mcp_catalog.db" - Update README.md to document relative path behavior	3 months ago

Rene Cannao	b3646b4798	Fix argument parsing and documentation in setup_test_db.sh Fixed critical issues with argument parsing that prevented the script from working correctly: 1. Fixed argument order - script now supports both: - ./setup_test_db.sh <command> [options] - ./setup_test_db.sh [options] <command> 2. Fixed --help option - now shows help instead of running commands 3. Updated README.md examples with correct syntax: - OLD: ./setup_test_db.sh --mode native start (wrong) - NEW: ./setup_test_db.sh start --mode native (correct) The script now properly: - Parses -h/--help anywhere and shows usage - Handles options before or after the command - Auto-detects mode when not specified - Shows helpful connection info after setup All examples in README.md updated with correct command syntax.	3 months ago
Rene Cannao	3d827144e8	Add required environment variables section to README Added comprehensive environment variable documentation to the README Prerequisites section to make it clear what needs to be configured before running the test scripts. Changes: - Added "Required Environment Variables" subsection under Prerequisites - Listed all ProxySQL Admin, MySQL, and MCP server environment variables - Added quick setup example for adding variables to ~/.bashrc - Made it clear that PROXYSQL_ADMIN_PASSWORD and MYSQL_PASSWORD need to be set Users now have clear guidance on required configuration before testing.	3 months ago
