WHAT IT DOES

What find_and_replace does on Code MCP Server

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

RISK

Why find_and_replace is rated Medium

This tool modifies file contents by replacing text across multiple files. While it has a 'preview option' suggesting changes can be reviewed before applying, the core action is writing/modifying data across potentially many files.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs find_and_replace safely

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

find_and_replace Rate-limited

find_and_replace 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.
