WHAT IT DOES

What intent_start does on Claude Mobile

AI agents invoke intent_start to trigger actions in Claude Mobile. 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.

RISK

Why intent_start is rated High

This tool executes external operations on an Android device by launching Activities with developer-controlled Intent parameters. While not a direct shell command execution, launching arbitrary Activities with specified data and actions can trigger side effects that depend on the intent arguments provided.

From the tool's definition Tool description states it 'Launch[es] an Activity with a structured Android Intent' and supports various intent parameters including 'action, component, data URI, category, typed extras, and activity flags'.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs intent_start safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Claude Mobile, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For intent_start, this is the rule to start with:

intent_start Rate-limited

intent_start 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.

How do I enforce a policy on intent_start? +

Register the Claude Mobile MCP server in PolicyLayer and add a rule for intent_start: 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 Claude Mobile. Nothing to install.

What risk level is intent_start? +

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

Can I rate-limit intent_start? +

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