WHEN AI AGENTS USE THIS TOOL

AI agents use rename_function_by_address to create or modify resources in Ghidra. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.

WHY ENFORCE A POLICY ON RENAME_FUNCTION_BY_ADDRESS

Without a policy, an AI agent could call rename_function_by_address repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Ghidra.

RECOMMENDED POLICY

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

ghidra.yaml 
tools:
  rename_function_by_address:
    rules:
      - action: allow
        rate_limit:
          max: 30
          window: 60

FREQUENTLY ASKED QUESTIONS

What does the rename_function_by_address tool do?

Rename a function by its memory address. It is categorised as a Write tool in the Ghidra MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on rename_function_by_address?

Add a rule in your Intercept YAML policy under the tools section for rename_function_by_address. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Ghidra MCP server.

What risk level is rename_function_by_address?

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

Can I rate-limit rename_function_by_address?

Yes. Add a rate_limit block to the rename_function_by_address rule in your Intercept 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 rename_function_by_address completely?

Set action: deny in the Intercept policy for rename_function_by_address. 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 rename_function_by_address?

rename_function_by_address is provided by the Ghidra MCP server (LaurieWired/GhidraMCP). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
