Flip one or more coins and show results as heads or tails.
AI agents call flip_coin to retrieve information from Dice Roller 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 random simulation and returns results without modifying any data, executing external commands, or triggering irreversible actions. It is functionally equivalent to a query or fetch operation that generates and returns stochastic output. The blast radius of misuse is minimal—an AI agent cannot cause harm by requesting coin flips.
From the tool's definition Tool name 'flip_coin' and description state it 'flip[s] one or more coins and show results as heads or tails' — a pure information retrieval operation with no side effects, data modification, code execution, or destructive capability.

Register the Dice Roller MCP Server MCP server in PolicyLayer and add a rule for flip_coin: 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 Dice Roller MCP Server. Nothing to install.
flip_coin 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 flip_coin 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 flip_coin. 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.
