WHAT IT DOES

What math_eval does on Symath-MCP

AI agents invoke math_eval to trigger actions in Symath-MCP. 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.

RISK

Why math_eval is rated High

The name 'math_eval' strongly suggests evaluating mathematical expressions, which falls under Execute. However, given the server context (symbolic mathematics), this is likely a safe computation tool rather than arbitrary code execution. The empty description significantly lowers confidence.

From the tool's definition Tool name contains 'eval', which typically implies evaluation/execution of expressions; description is empty and uninformative.

RECOMMENDED RULE

The rule that runs math_eval safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Symath-MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For math_eval, this is the rule to start with:

math_eval Rate-limited

math_eval 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.

The button opens the PolicyLayer dashboard: create your workspace, connect Symath-MCP, apply this rule, and every math_eval call is checked against it from then on.

FAQ

Questions about math_eval

What does the math_eval tool do? +

math_eval is a execute tool on the Symath MCP server. It is categorised as a Execute tool in the Symath-MCP 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_eval? +

Register the Symath MCP server in PolicyLayer and add a rule for math_eval: 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 Symath-MCP. Nothing to install.

What risk level is math_eval? +

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

Can I rate-limit math_eval? +

Yes. Add a rate_limit block to the math_eval 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_eval completely? +

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

math_eval is provided by the Symath MCP server (3akhp/math-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
