WHAT IT DOES

What add_grid_consumption does on Ha Nexus Agent

AI agents use add_grid_consumption to create or update resources in Ha Nexus Agent, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ha Nexus Agent environment.

RISK

Why add_grid_consumption is rated Medium

This tool creates or modifies energy dashboard settings (write operation) rather than reading data, executing arbitrary commands, or destroying data. The severity is medium because misconfiguration of energy monitoring flows could cause incorrect energy reporting but does not directly compromise security or enable destructive actions.

From the tool's definition The tool 'add_grid_consumption' creates or modifies the Energy Dashboard's grid source configuration by adding a 'flow_from' entry. This is a state-mutating operation that updates dashboard configuration.

RECOMMENDED RULE

The rule that runs add_grid_consumption safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Ha Nexus Agent, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For add_grid_consumption, this is the rule to start with:

add_grid_consumption Rate-limited

add_grid_consumption stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

How do I enforce a policy on add_grid_consumption? +

Register the Ha Nexus Agent MCP server in PolicyLayer and add a rule for add_grid_consumption: 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 Ha Nexus Agent. Nothing to install.

What risk level is add_grid_consumption? +

add_grid_consumption is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit add_grid_consumption? +

Yes. Add a rate_limit block to the add_grid_consumption 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.

How do I block add_grid_consumption completely? +

Set action: deny in the PolicyLayer policy for add_grid_consumption. 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.

What MCP server provides add_grid_consumption? +
