What modular_arithmetic does on UnClick
AI agents call modular_arithmetic to retrieve information from UnClick without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
a | number | Yes | Base value. |
b | number | — | Exponent (required for modpow). |
m | number | Yes | Modulus (positive integer). |
operation | string | Yes | Operation: modpow, modinverse, or mod. |
Parameters from the server's own tool schema.
Why modular_arithmetic is rated Low
Modular arithmetic operations are read-only mathematical calculations that retrieve computed results without creating, modifying, deleting, or executing external code. They have no blast radius when misused by an AI agent beyond potentially incorrect mathematical results.
From the tool's definition Tool performs pure mathematical computations (modpow, modinverse, mod) with no side effects, data modification, or external operations. Description explicitly lists mathematical operations only.
Attacks that exploit this kind of access
The rule that runs modular_arithmetic safely
PolicyLayer is an MCP gateway: it sits between your AI agents and UnClick, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For modular_arithmetic, this is the rule to start with:
modular_arithmetic is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect UnClick, apply this rule, and every modular_arithmetic call is checked against it from then on.
Questions about modular_arithmetic
Modular arithmetic operations: modpow (a^b mod m), modinverse (a^-1 mod m), or mod (a mod m). It is categorised as a Read tool in the UnClick MCP Server, which means it retrieves data without modifying state.
modular_arithmetic accepts 4 parameters: a, b, m, operation. Required: a, m, operation. The full parameter table on this page comes from the server's own tool schema.
Register the UnClick MCP server in PolicyLayer and add a rule for modular_arithmetic: 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 UnClick. Nothing to install.
modular_arithmetic 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 modular_arithmetic 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 modular_arithmetic. 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.
modular_arithmetic is provided by the UnClick MCP server (@unclick/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
