AI agents call mikey_math_comb 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.
This tool retrieves mathematical results without creating, modifying, deleting, executing external code, or affecting financial systems. It is a mathematical computation function analogous to a query that reads data and returns results. Even if misused by an AI agent, it cannot cause harm—it only performs arithmetic operations on numbers provided as arguments.
From the tool's definition The tool computes combinatorial mathematical functions (binomial coefficient, permutation, factorial) which are pure mathematical calculations with no side effects.
Attacks that exploit this kind of access
Combinatorics: binomial coefficient C(n,k), permutation P(n,k), or factorial. 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_comb: 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_comb 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_comb 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_comb. 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_comb 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.
