Calculate carbon equivalencies for a given kilowatt-hour value.
AI agents call emissions_equivalencies 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 read-only calculation that transforms an input value (kilowatt-hours) into equivalent carbon emissions using reference data. It retrieves or computes information without modifying any data, executing external commands, or causing irreversible changes. The low severity reflects minimal blast radius—misuse would only produce incorrect advisory information, not compromise systems or data integrity.
From the tool's definition Tool name 'emissions_equivalencies' and description 'Calculate carbon equivalencies' indicate a pure calculation/transformation of input data with no state changes, data modification, deletion, code execution, or external side effects.
Attacks that exploit this kind of access
Calculate carbon equivalencies for a given kilowatt-hour value. 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 emissions_equivalencies: 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.
emissions_equivalencies 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 emissions_equivalencies 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 emissions_equivalencies. 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.
emissions_equivalencies 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.
