grep_script
AI agents call grep_script to retrieve information from GameDevBench MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The name 'grep_script' strongly implies a read-only search operation (grep is a standard text search tool). However, the description is empty, which lowers confidence. Based on the name alone and the context of sibling tools (find_in_file suggests similar read operations), this is most likely a Read operation that searches script files for patterns. No side effects are expected from a grep-like operation.
From the tool's definition Tool name 'grep_script' suggests a search/pattern-matching operation on scripts, similar to the grep command which reads and searches file contents without modifying them.
Attacks that exploit this kind of access
grep_script. It is categorised as a Read tool in the GameDevBench MCP MCP Server, which means it retrieves data without modifying state.
Register the GameDevBench MCP server in PolicyLayer and add a rule for grep_script: 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 GameDevBench MCP. Nothing to install.
grep_script 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_script 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_script. 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_script is provided by the GameDevBench MCP server (seeleai/gamedevbench-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
grep_script is one line of GameDevBench's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
