What number_converter does on Math MCP Server
AI agents call number_converter to retrieve information from Math MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why number_converter is rated Low
The tool name suggests data retrieval/transformation of numerical values without modification of persistent state. Although the description is empty and reduces confidence, the name implies a read-only computation. Converted numbers would be returned to the user without creating, modifying, deleting, or executing external operations. Severity is low because number conversion has minimal blast radius even if misused.
From the tool's definition Tool name 'number_converter' suggests a utility that converts between number formats or bases (e.g., decimal to binary, hexadecimal conversion). No description provided to confirm function.
Attacks that exploit this kind of access
The rule that runs number_converter safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Math MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For number_converter, this is the rule to start with:
number_converter 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 Math MCP Server, apply this rule, and every number_converter call is checked against it from then on.
Questions about number_converter
number_converter is a read tool on the Math MCP Server MCP server. It is categorised as a Read tool in the Math MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Math MCP Server MCP server in PolicyLayer and add a rule for number_converter: 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 Math MCP Server. Nothing to install.
number_converter 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 number_converter 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 number_converter. 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.
number_converter is provided by the Math MCP Server MCP server (111-test-111/math-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
