Roll the dice with the given notation
AI agents call roll_dice to retrieve information from Tavily Web Search MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool simply computes and returns a random outcome based on dice notation (e.g., 2d6, 3d20). It is a pure read operation that queries a pseudo-random number generator and returns the result without altering any state or external systems. No data is created, modified, deleted, or persisted. This is a benign utility function.
From the tool's definition The tool 'roll_dice' with description 'Roll the dice with the given notation' performs a computational operation that generates random values but produces no side effects, modifies no data, executes no external commands, and performs no financial transactions.
Attacks that exploit this kind of access
Roll the dice with the given notation. It is categorised as a Read tool in the Tavily Web Search MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Tavily Web Search MCP Server MCP server in PolicyLayer and add a rule for roll_dice: 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 Tavily Web Search MCP Server. Nothing to install.
roll_dice 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 roll_dice 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 roll_dice. 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.
roll_dice is provided by the Tavily Web Search MCP Server MCP server (nilay320/mcp-session-code). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
