swipe · React Native MCP: Risk & Policy

WHAT IT DOES

What swipe does on React Native

AI agents invoke swipe to trigger actions in React Native. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why swipe needs a policy

The swipe tool triggers a UI interaction (a gesture) on a device or emulator, which is an external operation that can navigate screens, open drawers, trigger actions, or scroll content. This falls under Execute as it performs a browser/app action whose effects depend on arguments (coordinates and direction). Misuse could navigate to unintended screens or trigger unintended UI actions, giving it medium severity.

From the tool's definition Swipe from (x1,y1) to (x2,y2) in points... For scrolling and drawers.

Verdict

swipe Rate-limited

swipe stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches React Native, so you can run agents against it safely.

FAQ

Questions about swipe

What does the swipe tool do? +

Swipe from (x1,y1) to (x2,y2) in points. Get coordinates from query_selector. For scrolling and drawers. It is categorised as a Execute tool in the React Native MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on swipe? +

Register the React Native MCP server in PolicyLayer and add a rule for swipe: 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 React Native. Nothing to install.

What risk level is swipe? +

swipe is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit swipe? +

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

Set action: deny in the PolicyLayer policy for swipe. 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 swipe? +

swipe is provided by the React Native MCP server (@ohah/react-native-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
