WHAT IT DOES

What spasql_query does on OpenLink MCP Server for ODBC

AI agents invoke spasql_query to trigger actions in OpenLink MCP Server for ODBC. 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 spasql_query needs a policy

Executing arbitrary SPASQL queries can perform reads but also potentially trigger writes, updates, or destructive operations depending on the query content. The 'execute' verb and query execution nature place this in the Execute category.

From the tool's definition 'Execute a SPASQL query and return results' — the tool actively executes a query (SPASQL, a hybrid SPARQL/SQL language) against an ODBC-accessible database.
