Convert weight between mg, g, kg, t, oz, and lb.
AI agents call convert_weight to retrieve information from Unit Expert MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a stateless mathematical conversion between weight units. It only computes and returns a value; it does not read from or write to any data store, execute code, or trigger any external operation. Misuse potential is essentially zero.
From the tool's definition "Convert weight between mg, g, kg, t, oz, and lb" — pure unit conversion with no side effects, data storage, or external operations.
Attacks that exploit this kind of access
Convert weight between mg, g, kg, t, oz, and lb. It is categorised as a Read tool in the Unit Expert MCP MCP Server, which means it retrieves data without modifying state.
Register the Unit Expert MCP server in PolicyLayer and add a rule for convert_weight: 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 Unit Expert MCP. Nothing to install.
convert_weight 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 convert_weight 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 convert_weight. 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.
convert_weight is provided by the Unit Expert MCP server (kdaehun00/unit-expert-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
