create_query · Redash MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_query does on Redash MCP Server

AI agents use create_query to create or update resources in Redash MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Redash MCP Server environment.

WHY IT NEEDS A POLICY

Why create_query needs a policy

Creating a query is a write operation that adds a new record to Redash's data store. This is reversible (the query can be deleted or modified). The severity is medium because misuse could result in numerous unused queries cluttering the system, but the actual blast radius depends on subsequent execution of those queries by other tools (execute_query, execute_raw_query).

From the tool's definition Tool description explicitly states 'Create a new query in Redash'. The action is to create (Write category) a new query object, which is a reversible operation. The query itself is inert data until executed.

Verdict

create_query Rate-limited

create_query stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
