WHAT IT DOES

What add_node does on Godot MCP

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

RISK

Why add_node is rated Medium

Adding a node to a scene is a reversible write operation that modifies project state. It creates new structural elements but can be undone (nodes can be removed). This is less severe than Destructive (which would be irreversible deletion) but more impactful than Read operations.

From the tool's definition Tool description states 'Add a node to an existing scene' — directly creates/modifies scene structure in a Godot project. The sibling tools confirm this is a development environment (create_scene, edit_node, export_mesh_library, launch_editor).

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs add_node safely

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

add_node Rate-limited

add_node 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 Godot MCP, apply this rule, and every add_node call is checked against it from then on.

FAQ

Questions about add_node

What does the add_node tool do? +

Add a node to an existing scene. It is categorised as a Write tool in the Godot MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on add_node? +

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

What risk level is add_node? +

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

Can I rate-limit add_node? +

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

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

add_node is provided by the Godot MCP server (6ninelives/godot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
