Rename a PHP method, property, or constant and update all references project-wide. Uses type inference to only rename the correct member (not same-named members on other classes).
AI agents use phpactor_rename_member to create or update resources in Phpactor MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Phpactor MCP Server environment.
This is a Write operation because it creates or modifies data reversibly—renaming methods, properties, and constants throughout a PHP project are code modifications that can be undone. It is not Destructive because renaming is reversible and does not permanently delete or overwrite data.
From the tool's definition The tool description states it will 'Rename a PHP method, property, or constant and update all references project-wide.' This modifies code across the codebase in a reversible manner (renaming can be undone by renaming back), affecting multiple files.
Attacks that exploit this kind of access
Rename a PHP method, property, or constant and update all references project-wide. Uses type inference to only rename the correct member (not same-named members on other classes). It is categorised as a Write tool in the Phpactor MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Phpactor MCP Server MCP server in PolicyLayer and add a rule for phpactor_rename_member: 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 Phpactor MCP Server. Nothing to install.
phpactor_rename_member 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 phpactor_rename_member 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 phpactor_rename_member. 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.
phpactor_rename_member is provided by the Phpactor MCP Server MCP server (p4it-kft/p4it-phpactor-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
