@appium-mcp Write Risk 4/5

AI agents use setup_wda 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.

Without a policy, an AI agent could call setup_wda 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.

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

What does the setup_wda tool do? +

Download and set up WebDriverAgent for iOS. 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 setup_wda? +

Add a rule in your Intercept YAML policy under the tools section for setup_wda. 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 setup_wda? +

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

Can I rate-limit setup_wda? +

Yes. Add a rate_limit block to the setup_wda 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 setup_wda completely? +

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

setup_wda 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.
