WHAT IT DOES

What remainder does on MCP Server & Client Test Environment

AI agents call remainder to retrieve information from MCP Server & Client Test Environment without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

WHY IT NEEDS A POLICY

Why remainder needs a policy

This tool performs a simple arithmetic operation (modulo/remainder), computing the remainder of dividing two numbers. It has no side effects, does not modify data, and does not execute commands. It is a pure mathematical read/compute operation.

From the tool's definition remainder of two numbers divison

Questions about remainder

What does the remainder tool do? +

remainder of two numbers divison. It is categorised as a Read tool in the MCP Server & Client Test Environment MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on remainder? +

Register the MCP Server & Client Test Environment MCP server in PolicyLayer and add a rule for remainder: 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 & Client Test Environment. Nothing to install.

What risk level is remainder? +

remainder is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit remainder? +

Yes. Add a rate_limit block to the remainder 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.

How do I block remainder completely? +

Set action: deny in the PolicyLayer policy for remainder. 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.

What MCP server provides remainder? +

remainder is provided by the MCP Server & Client Test Environment MCP server (mayur11235/lets-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
