WHAT IT DOES

What plot_timeseries does on CLIO Adios

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

RISK

Why plot_timeseries is rated Medium

The tool reads CSV/Excel input data and generates a visualization artifact (PNG image file). This is a reversible write operation—the output file can be deleted or overwritten without affecting source data or system state. It does not execute arbitrary code, delete data, or trigger external operations beyond file I/O. The risk is low because the operation is non-destructive and limited in scope.

From the tool's definition Tool creates and outputs a PNG file ('Create a multi-series line chart PNG'), which involves writing image data to disk.

RECOMMENDED RULE

The rule that runs plot_timeseries safely

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

plot_timeseries Rate-limited

plot_timeseries 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.
