shelly_switch_set

// WHEN AI AGENTS USE THIS TOOL

AI agents use shelly_switch_set to create or modify resources in Shelly. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.

// WHY ENFORCE A POLICY ON SHELLY_SWITCH_SET

Without a policy, an AI agent could call shelly_switch_set repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Shelly.

// RECOMMENDED POLICY

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

shelly.yaml

tools:
  shelly_switch_set:
    rules:
      - action: allow
        rate_limit:
          max: 30
          window: 60

What does the shelly_switch_set tool do? +

Turn a relay switch on/off using Switch.Set.. It is categorised as a Write tool in the Shelly MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on shelly_switch_set? +

Add a rule in your Intercept YAML policy under the tools section for shelly_switch_set. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Shelly MCP server.

What risk level is shelly_switch_set? +

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

Can I rate-limit shelly_switch_set? +

Yes. Add a rate_limit block to the shelly_switch_set rule in your Intercept 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 shelly_switch_set completely? +

Set action: deny in the Intercept policy for shelly_switch_set. 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 shelly_switch_set? +

shelly_switch_set is provided by the Shelly MCP server (shelly-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Let agents act without letting them run wild.
