energy.solar-resource
NREL solar resource averages (NSRDB) for a lat/lon. Returns annual + monthly DNI (direct normal irradiance), GHI (global horizontal), and tilted-at-latitude irradiance in kWh/m²/day.

What energy.solar-resource does on Mcp
AI agents call energy.solar-resource to retrieve information from Mcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why energy.solar-resource is rated Low
This is a straightforward data retrieval tool that queries a public solar resource database and returns read-only information. It has no side effects, cannot modify data, execute code, or trigger financial transactions. The only minor consideration is that the data is returned from a pay-per-call service (2s.io), but the tool itself performs only a harmless lookup.
From the tool's definition Returns solar resource averages and irradiance data for a given latitude/longitude. No modification, deletion, or execution of external operations. Purely queries NREL NSRDB database and retrieves computed meteorological values (DNI, GHI, tilted irradiance).
Attacks that exploit this kind of access
The rule that runs energy.solar-resource safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For energy.solar-resource, this is the rule to start with:
energy.solar-resource is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Mcp, apply this rule, and every energy.solar-resource call is checked against it from then on.
Questions about energy.solar-resource
NREL solar resource averages (NSRDB) for a lat/lon. Returns annual + monthly DNI (direct normal irradiance), GHI (global horizontal), and tilted-at-latitude irradiance in kWh/m²/day. 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.solar-resource: 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.solar-resource 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.solar-resource 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.solar-resource. 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.solar-resource 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.
