Search for a regex pattern recursively. Respects .gitignore.
AI agents call grep to retrieve information from Cursor MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries data (search results) without side effects. It respects .gitignore boundaries, indicating a read-only operation limited to file content inspection. No data is modified, deleted, or executed.
From the tool's definition Tool name 'grep' and description 'Search for a regex pattern recursively. Respects .gitignore.' — performs pattern searching with no modification or execution capability.
Attacks that exploit this kind of access
Search for a regex pattern recursively. Respects .gitignore. It is categorised as a Read tool in the Cursor MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Cursor MCP Server MCP server in PolicyLayer and add a rule for grep: 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 Cursor MCP Server. Nothing to install.
grep is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the grep 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 grep. 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.
grep is provided by the Cursor MCP Server MCP server (tariqnasheed/cursor_mcp_server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
