Calculate a percentage of a value.
AI agents call calculate_percentage to retrieve information from MCP Multi-Tool 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 pure mathematical computation (percentage calculation) with no side effects, data modification, or external operations. It simply reads input values and returns a calculated result.

Attacks that exploit this kind of access
Calculate a percentage of a value. It is categorised as a Read tool in the MCP Multi-Tool Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Multi-Tool Server MCP server in PolicyLayer and add a rule for calculate_percentage: 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 Multi-Tool Server. Nothing to install.
calculate_percentage 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 calculate_percentage 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 calculate_percentage. 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.
calculate_percentage is provided by the MCP Multi-Tool Server MCP server (vipankumar87/mcp-example). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
