Which electric utility serves a US lat/lng + a summary of its published rate plans, from OpenEI URDB (CC0). Each plan: utility, rate name, sector, EIA utility id, fixed monthly charge, first-tier energy rate ($/kWh), tariff link. For solar/EV/storage economics, bill estimation, and
AI agents call energy.utility-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 data retrieval tool that queries a public, read-only database to provide utility rate information for analysis purposes (solar economics, bill estimation). It has no side effects, cannot modify data, and presents no destructive or financial risk on its own—it merely supplies information consumers would use for their own downstream financial decisions.
From the tool's definition Tool retrieves published utility rate plan data from OpenEI URDB (CC0) based on geographic coordinates. Returns informational fields: utility name, rate name, sector, EIA ID, fixed charges, energy rates, and tariff links.

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.utility-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.utility-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.utility-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.utility-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.utility-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.
