tan of a number
AI agents call tan to retrieve information from Math MCP Server for MacOS without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool computes the tangent of a number, which is a read-only mathematical operation. It retrieves a computed value without modifying any state, executing commands, or interacting with external systems. Minimal blast radius if misused.
From the tool's definition 'tan of a number' — pure mathematical computation with no side effects
Attacks that exploit this kind of access
tan of a number. It is categorised as a Read tool in the Math MCP Server for MacOS MCP Server, which means it retrieves data without modifying state.
Register the Math MCP Server for MacOS MCP server in PolicyLayer and add a rule for tan: 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 Math MCP Server for MacOS. Nothing to install.
tan 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 tan 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 tan. 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.
tan is provided by the Math MCP Server for MacOS MCP server (rohinigaonkar/mcp-math-macos). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
