WHAT IT DOES

What append_rows does on Integrations MCP

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

RISK

Why append_rows is rated Medium

The name 'append_rows' strongly implies a write operation — adding new rows to some data store (likely a spreadsheet or table, given the context of tools like airtable_create_record on the same server). Appending is a reversible write operation. Severity is medium due to potential for data corruption or unintended bulk inserts. Confidence is lowered due to empty description.

From the tool's definition Tool name 'append_rows' suggests adding rows to a dataset or spreadsheet; description is empty and uninformative.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs append_rows safely

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

append_rows Rate-limited

append_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.
