This tool creates a new chart artifact, which is a write operation that modifies the state of visualizations in the system. It is reversible (unlike destructive operations) and does not involve code execution, external system commands, financial transactions, or data retrieval.

From the tool's definition Tool name is 'create_chart' with description 'Create a new data visualization chart'. The verb 'Create' indicates data creation/modification. Chart creation is reversible (charts can be deleted or regenerated).

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_chart safely

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

create_chart Rate-limited

create_chart 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.
