Why create_spreadsheet is rated Medium
Creating a new spreadsheet is a reversible Write operation that establishes new persistent data storage. The high severity reflects that an AI agent could create many spreadsheets, consume quota, and clutter organizational infrastructure. The approval gating mentioned in the notes ('[write-tier...manager's approval]') further confirms this is classified as a sensitive Write action by the server itself.
From the tool's definition Tool name 'create_spreadsheet' and description 'Create a new Google Spreadsheet with optional headers' explicitly performs a create operation on cloud-hosted data.
Attacks that exploit this kind of access
The rule that runs create_spreadsheet safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Freedom Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_spreadsheet, this is the rule to start with:
create_spreadsheet 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Freedom Mcp, apply this rule, and every create_spreadsheet call is checked against it from then on.
