WHAT IT DOES

What create_notebook_design does on Funky Junction

AI agents use create_notebook_design 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_notebook_design needs a policy

This tool creates a new design artifact (a quantum circuit design) which is a reversible operation - designs can be modified, overwritten, or deleted after creation. This fits the Write category rather than Read (it generates new data rather than just retrieving it) or Execute (it's not running code or triggering external operations, but rather generating a design output).

From the tool's definition Tool description states 'Create the complete quantum circuit design' - the verb 'Create' indicates data creation/generation. The tool generates and persists a complete quantum circuit design artifact from a notebook.

Verdict

create_notebook_design Rate-limited

create_notebook_design 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.

FAQ

Questions about create_notebook_design

What does the create_notebook_design tool do? +

Create the complete quantum circuit design from the notebook with all components. It is categorised as a Write tool in the Funky Junction MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create_notebook_design? +

Register the Funky Junction MCP server in PolicyLayer and add a rule for create_notebook_design: 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 Funky Junction. Nothing to install.

What risk level is create_notebook_design? +

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

Can I rate-limit create_notebook_design? +

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

Set action: deny in the PolicyLayer policy for create_notebook_design. 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 create_notebook_design? +

create_notebook_design is provided by the Funky Junction MCP server (paulgoldschmidt/qsim-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
