Calculate carbon emissions from electricity consumption in Australian states
AI agents call electricity_emission to retrieve information from Mcp Carbon Calculator without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a deterministic calculation based on input values and returns results without modifying any data, executing external commands, or triggering state changes. It is purely informational - users provide consumption data and receive emissions metrics. No data is created, destroyed, or altered in any system. This is a classic Read operation: query-based data retrieval with no side effects.
From the tool's definition Tool description states it 'Calculate[s] carbon emissions' - a computational query operation that retrieves calculated emissions data based on input parameters (electricity consumption and state).
Attacks that exploit this kind of access
Calculate carbon emissions from electricity consumption in Australian states. It is categorised as a Read tool in the Mcp Carbon Calculator MCP Server, which means it retrieves data without modifying state.
Register the Mcp Carbon Calculator MCP server in PolicyLayer and add a rule for electricity_emission: 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 Carbon Calculator. Nothing to install.
electricity_emission 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 electricity_emission 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 electricity_emission. 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.
electricity_emission is provided by the Mcp Carbon Calculator MCP server (prdai/mcp-carbon-calculator). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
