Roll a dice with a specified number of sides and return the result.
AI agents call getDiceRoll to retrieve information from MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a stateless computation (random number generation) and only returns data without creating, modifying, deleting, or executing any external operations. It has no impact on system state or data persistence. The blast radius of misuse is negligible.
From the tool's definition Tool name 'getDiceRoll' and description 'Roll a dice with a specified number of sides and return the result' indicates a pure read operation that returns a random number without side effects.

Roll a dice with a specified number of sides and return the result. It is categorised as a Read tool in the MCP Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Server MCP server in PolicyLayer and add a rule for getDiceRoll: 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 MCP Server. Nothing to install.
getDiceRoll 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 getDiceRoll 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 getDiceRoll. 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.
getDiceRoll is provided by the MCP Server MCP server (jeongjaesoon/sample-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
