WHAT IT DOES

What append_pkg does on CLIO Adios

AI agents use append_pkg 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 append_pkg is rated Medium

This tool modifies a pipeline configuration by adding a package to it. This is a reversible write operation (the package could be removed), so it falls under Write. The blast radius is medium since misconfiguration of a pipeline could affect scientific workflows.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

append_pkg Rate-limited

append_pkg 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.

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect CLIO Adios, apply this rule, and every append_pkg call is checked against it from then on.

Can I rate-limit append_pkg? +

Yes. Add a rate_limit block to the append_pkg 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 append_pkg completely? +
