select_device
Select a specific device
Part of the Appium MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
WHEN AI AGENTS USE THIS TOOL
AI agents use select_device to create or modify resources in Appium. 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 SELECT_DEVICE
Without a policy, an AI agent could call select_device 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 Appium.
RECOMMENDED POLICY
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

FREQUENTLY ASKED QUESTIONS
What does the select_device tool do?
Select a specific device. It is categorised as a Write tool in the Appium MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
How do I enforce a policy on select_device?
Add a rule in your Intercept YAML policy under the tools section for select_device. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Appium MCP server.
What risk level is select_device?
select_device is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Can I rate-limit select_device?
Yes. Add a rate_limit block to the select_device 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 select_device completely?
Set action: deny in the Intercept policy for select_device. 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 select_device?
select_device is provided by the Appium MCP server (appium-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
