두 숫자와 연산자를 입력하면 계산 결과를 반환합니다.
AI agents call calc to retrieve information from TypeScript MCP Server Boilerplate without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a simple arithmetic calculation and returns the result. It has no side effects, does not modify any data, and does not execute external commands. It is purely a read/query operation with minimal blast radius.
From the tool's definition 두 숫자와 연산자를 입력하면 계산 결과를 반환합니다 — 'returns calculation result' for two numbers and an operator

두 숫자와 연산자를 입력하면 계산 결과를 반환합니다. It is categorised as a Read tool in the TypeScript MCP Server Boilerplate MCP Server, which means it retrieves data without modifying state.
Register the TypeScript MCP Server Boilerplate MCP server in PolicyLayer and add a rule for calc: 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 TypeScript MCP Server Boilerplate. Nothing to install.
calc 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 calc 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 calc. 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.
calc is provided by the TypeScript MCP Server Boilerplate MCP server (junwoo0406/my-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
