What math_solve does on Chain of Draft (CoD) MCP Server

AI agents invoke math_solve to trigger actions in Chain of Draft (CoD) MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

Why math_solve needs a policy

This tool runs a computational reasoning process (Chain of Draft) to solve math problems. It executes logic and generates outputs, making it Execute rather than Read (it's not retrieving existing data) or Write (it's not persisting data). The blast radius is low since it only performs mathematical computation with no side effects on external systems, data stores, or finances.

From the tool's definition "Solve a math problem using Chain of Draft reasoning" — executes a reasoning/computation process to produce an answer

Documented attack patterns abuse exactly the kind of access math_solve gives an agent:

How to control math_solve

PolicyLayer is an MCP gateway — it sits between your AI agents and Chain of Draft (CoD) MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for math_solve:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "math_solve": {
      "limits": [
        {
          "counter": "math_solve_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

math_solve stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

  1. Create a free account and register Chain of Draft (CoD) MCP Server — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

Questions about math_solve

What does the math_solve tool do? +

Solve a math problem using Chain of Draft reasoning. It is categorised as a Execute tool in the Chain of Draft (CoD) MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on math_solve? +

Register the Chain of Draft (CoD) MCP Server MCP server in PolicyLayer and add a rule for math_solve: 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 Chain of Draft (CoD) MCP Server. Nothing to install.

What risk level is math_solve? +

math_solve is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit math_solve? +

Yes. Add a rate_limit block to the math_solve 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 math_solve completely? +

Set action: deny in the PolicyLayer policy for math_solve. 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 math_solve? +

math_solve is provided by the Chain of Draft (CoD) MCP Server MCP server (stat-guy/chain-of-draft). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Chain of Draft (CoD) MCP Server tool call.

Start from Chain of Draft (CoD) MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
