WHAT IT DOES

What podbc_execute_query_md does on MCP PyODBC Server

AI agents invoke podbc_execute_query_md to trigger actions in MCP PyODBC Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why podbc_execute_query_md needs a policy

This tool executes arbitrary SQL queries against a database via ODBC connections. While the description emphasizes querying, SQL execution is fundamentally an Execute-category action because the effects depend entirely on the query argument—it could read data (Read), modify it (Write), delete it (Destructive), or trigger stored procedures with side effects.

From the tool's definition Tool name contains 'execute_query' and description states 'Execute a SQL query'. The server description indicates support for arbitrary database querying through ODBC, including Virtuoso DBMS.
