Retail electricity price + sales for a US state by customer sector (residential/commercial/industrial/transportation/all), monthly newest-first, from EIA. Returns price (cents/kWh), sales (MWh), revenue ($M), customers. More granular than energy.prices (national benchmark only).
AI agents call energy.electricity-rates to retrieve information from Mcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a pure data retrieval tool that queries historical electricity pricing and sales statistics by state and sector. It has no side effects, cannot modify data, execute operations, or commit financial transactions. The data returned is informational reference material for analysis only. The 'pay-per-call' settlement mechanism is orthogonal to the tool's function—it is still fundamentally a Read operation.
From the tool's definition Tool retrieves and returns electricity rate data: 'Returns price (cents/kWh), sales (MWh), revenue ($M), customers' from EIA. No modification, deletion, or execution capability mentioned. Described as providing historical/reference data 'monthly newest-first'.

Retail electricity price + sales for a US state by customer sector (residential/commercial/industrial/transportation/all), monthly newest-first, from EIA. Returns price (cents/kWh), sales (MWh), revenue ($M), customers. More granular than energy.prices (national benchmark only). It is categorised as a Read tool in the Mcp MCP Server, which means it retrieves data without modifying state.
Register the MCP server in PolicyLayer and add a rule for energy.electricity-rates: 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. Nothing to install.
energy.electricity-rates 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 energy.electricity-rates 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 energy.electricity-rates. 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.
energy.electricity-rates is provided by the MCP server (@2sio/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
