WHAT IT DOES

What histogram_plot does on CLIO Adios

AI agents use histogram_plot 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 histogram_plot is rated Medium

An AI agent can call histogram_plot faster than any human can review: one bad instruction and it creates or modifies resources in CLIO Adios by the hundred, each call as confident as the last.

RECOMMENDED RULE

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

histogram_plot Rate-limited

histogram_plot 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 CLIO Adios, apply this rule, and every histogram_plot call is checked against it from then on.

FAQ

Questions about histogram_plot

What does the histogram_plot tool do? +

Create a histogram from CSV or Excel data showing value distribution. It is categorised as a Write tool in the CLIO Adios MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on histogram_plot? +

Register the CLIO Adios MCP server in PolicyLayer and add a rule for histogram_plot: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches CLIO Adios. Nothing to install.

What risk level is histogram_plot? +

histogram_plot is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit histogram_plot? +

Yes. Add a rate_limit block to the histogram_plot rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block histogram_plot completely? +

Set action: deny in the PolicyLayer policy for histogram_plot. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides histogram_plot? +

histogram_plot is provided by the CLIO Adios MCP server (pypi:clio-kit). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
