WHAT IT DOES

What gcp_bq_run_query does on GCP MCP Server

AI agents invoke gcp_bq_run_query to trigger actions in GCP MCP 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.

RISK

Why gcp_bq_run_query is rated High

This tool executes SQL queries against BigQuery, which qualifies as Execute since it triggers external operations (SQL execution) whose effects depend entirely on the query argument provided by the user.

From the tool's definition Tool name 'gcp_bq_run_query' and description 'Run a BigQuery SQL query' indicate execution of arbitrary SQL queries. BigQuery is a data warehouse where SQL queries can read, modify, or delete data depending on query content.

RECOMMENDED RULE

The rule that runs gcp_bq_run_query safely

PolicyLayer is an MCP gateway: it sits between your AI agents and GCP MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For gcp_bq_run_query, this is the rule to start with:

gcp_bq_run_query Rate-limited

gcp_bq_run_query stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

    }
  }
}

The button opens the PolicyLayer dashboard: create your workspace, connect GCP MCP Server, apply this rule, and every gcp_bq_run_query call is checked against it from then on.
