WHAT IT DOES

What gh_connect_many does on Rhino

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

RISK

Why gh_connect_many is rated Medium

Adding wires in Grasshopper modifies the parametric definition by creating new connections between components. This is a Write operation because it creates/modifies data structures (component connections) that define the geometry pipeline. It is reversible (wires can be deleted).

From the tool's definition Tool description states 'Add multiple wires in a single round-trip', which creates connections (wires) between Grasshopper components. This is a reversible modification operation.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs gh_connect_many safely

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

gh_connect_many Rate-limited

gh_connect_many 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 Rhino, apply this rule, and every gh_connect_many call is checked against it from then on.

FAQ

Questions about gh_connect_many

What does the gh_connect_many tool do? +

Add multiple wires in a single round-trip. It is categorised as a Write tool in the Rhino MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on gh_connect_many? +

Register the Rhino MCP server in PolicyLayer and add a rule for gh_connect_many: 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 Rhino. Nothing to install.

What risk level is gh_connect_many? +

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

Can I rate-limit gh_connect_many? +

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

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

gh_connect_many is provided by the Rhino MCP server (easehee/rhino-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
