AI agents call mikey_math_mod to retrieve information from Mcp Math without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Modular arithmetic operations are stateless mathematical computations. They compute results based on inputs (e.g., modular exponentiation, modular inverse) but do not create, modify, delete, or trigger external operations. This fits the Read category of retrieving or computing data with no side effects.
From the tool's definition Tool performs modular arithmetic operations (power, inverse, simple mod) which are mathematical computations that retrieve or compute values without modifying state.
Attacks that exploit this kind of access
Modular arithmetic: power, inverse, or simple mod. It is categorised as a Read tool in the Mcp Math MCP Server, which means it retrieves data without modifying state.
Register the Mcp Math MCP server in PolicyLayer and add a rule for mikey_math_mod: 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 Math. Nothing to install.
mikey_math_mod 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 mikey_math_mod 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 mikey_math_mod. 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.
mikey_math_mod is provided by the Mcp Math MCP server (mikeybeez/mcp-math). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
