create_transmons · Funky Junction MCP: Risk & Policy

WHAT IT DOES

What create_transmons does on Funky Junction

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

WHY IT NEEDS A POLICY

Why create_transmons needs a policy

This tool creates new design components (transmon qubits Q1 and Q2) within a circuit design. This is a Write operation because it creates new data structures that can be modified or removed later. There is no irreversible deletion, financial impact, or code execution involved. The blast radius is limited to the design artifact being modified, making severity low.

From the tool's definition Tool name 'create_transmons' and description 'Add transmon pockets Q1 and Q2 to the design' indicate creation of design elements. 'Add' is a write operation that modifies the quantum circuit design reversibly.

create_transmons Rate-limited

create_transmons 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.

What risk level is create_transmons? +

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

Can I rate-limit create_transmons? +
