Return the projected electricity-grid carbon intensity for a region, hour by hour. Use this when deciding whether to run an expensive AI task now or defer it. Carbon intensity is reported in grams CO2-equivalent per kWh, with a categorical band (very_clean / clean / average / dirty / very_dirty).
AI agents call get_grid_forecast to retrieve information from Ebb Ai without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves forecast data (grid carbon intensity projections) without modifying, executing operations, or triggering external side effects. It is informational only, used to support scheduling decisions made by other tools. Even if the data were inaccurate, no harm could occur from the read operation itself—only from downstream decisions.
From the tool's definition Tool description states it 'Return[s] the projected electricity-grid carbon intensity' — a pure data retrieval operation with no side effects.

Return the projected electricity-grid carbon intensity for a region, hour by hour. Use this when deciding whether to run an expensive AI task now or defer it. Carbon intensity is reported in grams CO2-equivalent per kWh, with a categorical band (very_clean / clean / average / dirty / very_dirty). It is categorised as a Read tool in the Ebb Ai MCP Server, which means it retrieves data without modifying state.
Register the Ebb Ai MCP server in PolicyLayer and add a rule for get_grid_forecast: 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 Ebb Ai. Nothing to install.
get_grid_forecast 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 get_grid_forecast 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 get_grid_forecast. 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.
get_grid_forecast is provided by the Ebb Ai MCP server (vitalini/ebb-ai). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
