AI agents use debug_attach to create or modify resources in Mobai. 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 debug_attach repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Mobai.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access debug_attach gives an agent. Each links to the full case and the policy that stops it:
Other write tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Start a debug session for an iOS app. Provide either bundle_id (launches and attaches) or pid (attaches to a running process). Optional breakpoints[] are armed before the target resumes. Read mobai://reference/debugging first.. It is categorised as a Write tool in the Mobai MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Mobai MCP server in PolicyLayer and add a rule for debug_attach: 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 Mobai. Nothing to install.
debug_attach is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the debug_attach 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.
Set action: deny in the PolicyLayer policy for debug_attach. 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.
debug_attach is provided by the Mobai MCP server (MobAI-App/mobai-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
