AI agents use rename_function to create or update resources in CutterMCP-plus — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your CutterMCP-plus environment.
Renaming a function is a reversible modification operation that changes project state but does not delete data or execute arbitrary code. It fits the Write category (creates or modifies data reversibly). Severity is medium because misuse could corrupt a reverse engineering project's annotation integrity or mislead analysis, but the change can be undone.
From the tool's definition Tool name is 'rename_function' and description states 'Rename a function.' This modifies metadata (the function name) within a reverse engineering project.
Documented attack patterns abuse exactly the kind of access rename_function gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and CutterMCP-plus, and nothing reaches the server without passing your rules. This is the rule we recommend for rename_function:
{
"version": "1",
"default": "deny",
"tools": {
"rename_function": {
"limits": [
{
"counter": "rename_function_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}rename_function 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.

Rename a function. It is categorised as a Write tool in the CutterMCP-plus MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the CutterMCP-plus MCP server in PolicyLayer and add a rule for rename_function: 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 CutterMCP-plus. Nothing to install.
rename_function is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the rename_function 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.
Set action: deny in the PolicyLayer policy for rename_function. 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.
rename_function is provided by the CutterMCP-plus MCP server (restkhz/cuttermcp-plus). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
