Calculate carbon emissions from gas consumption in non-metropolitan areas of Australian states
AI agents call gas_emission_non_metro 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 is a pure calculation tool that retrieves emission factors from official National Greenhouse Accounts 2024 data and computes results based on consumption input. No data is written, deleted, modified, executed externally, or committed financially. The tool simply reads data and returns computed results, matching the Read category definition of 'retrieves or queries data; no side effects'.
From the tool's definition Tool 'gas_emission_non_metro' performs carbon emission calculations from gas consumption data. It 'calculates' emissions, a computational read operation with no side effects, state/data mutation, code execution, financial transactions, or destructive actions.
Attacks that exploit this kind of access
Calculate carbon emissions from gas consumption in non-metropolitan areas of 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 gas_emission_non_metro: 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.
gas_emission_non_metro 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 gas_emission_non_metro 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 gas_emission_non_metro. 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.
gas_emission_non_metro 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.
