grep

What grep does on CoWork OS

AI agents call grep to retrieve information from CoWork OS without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why grep is rated Low

grep is a read-only operation that retrieves and displays matching content from files. It has no side effects, does not execute code, does not modify data, and does not delete anything. It is analogous to standard grep/search utilities. The low severity reflects minimal blast radius—even if an AI agent misuses regex patterns, the worst outcome is a noisy or failed search, not data loss or unauthorized actions.

From the tool's definition Tool name 'grep' and description 'Powerful regex-based content search across files' indicates searching/querying file contents without modification or execution capabilities.

The rule that runs grep safely

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

{
  "version": "1",
  "default": "deny",
  "tools": {
    "grep": {}
  }
}
