WHAT IT DOES

What cs_dbg_set_variable does on Godot Breakpoint

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

RISK

Why cs_dbg_set_variable is rated Medium

This tool writes/modifies a variable's value in a running Godot debug session. While it's reversible in principle (the variable can be changed back), it directly affects program state during execution, making it a Write operation. Severity is high because modifying variables during a debug session can alter game state, cause crashes, or produce unpredictable behavior in the running application.

From the tool's definition "Change a variable" — modifies a variable during a debug session

RECOMMENDED RULE

The rule that runs cs_dbg_set_variable safely

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

cs_dbg_set_variable Rate-limited

cs_dbg_set_variable 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.

Questions about cs_dbg_set_variable

What does the cs_dbg_set_variable tool do? +

How do I enforce a policy on cs_dbg_set_variable? +

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

What risk level is cs_dbg_set_variable? +

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

Can I rate-limit cs_dbg_set_variable? +

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

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

cs_dbg_set_variable is provided by the Godot Breakpoint MCP server (jlivingston-Cipher/godot-breakpoint-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
