dsql_lint · Amazon MQ MCP Server MCP: Risk & Policy

WHAT IT DOES

What dsql_lint does on Amazon MQ MCP Server

AI agents call dsql_lint as a supporting operation in Amazon MQ MCP Server workflows.

WHY IT NEEDS A POLICY

Why dsql_lint needs a policy

The description is empty and uninformative. The name 'dsql_lint' suggests a linting or static analysis tool (possibly for DSQL/distributed SQL), which would be a Read/Execute category, but without confirmation I default to Other with low confidence. Lint tools generally only read and analyze code without side effects, so severity is low.

From the tool's definition Tool name 'dsql_lint' and empty description provide no clear indication of what the tool does. 'lint' typically implies static analysis/read-only checks, but this cannot be confirmed.
