WHAT IT DOES

What gcp_bq_insert_rows does on GCP MCP Server

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

RISK

Why gcp_bq_insert_rows is rated Medium

The tool creates or modifies data (inserts rows) in a reversible manner—data can be queried and deleted later. This is a Write operation rather than Read (no retrieval) or Destructive (insertion is not irreversible). Severity is high because malicious or erroneous insertions could corrupt data integrity, pollute analytics pipelines, or incur significant BigQuery costs at scale, especially with streaming writes.

From the tool's definition Tool name 'gcp_bq_insert_rows' and description 'Insert rows into a BigQuery table (streaming)' indicate creation of new data records in a database table.

RECOMMENDED RULE

The rule that runs gcp_bq_insert_rows 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_insert_rows, this is the rule to start with:

gcp_bq_insert_rows Rate-limited

gcp_bq_insert_rows 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.
