simulator_keychain

Manipulate the device keychain: add root certificates, add certificates, or reset the entire keychain.

Part of the Preflight Ios MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

// WHEN AI AGENTS USE THIS TOOL

AI agents may call simulator_keychain to permanently remove or destroy resources in Preflight Ios. Without a policy, an autonomous agent could delete critical data in a loop with no way to undo the damage. Intercept blocks destructive tools by default and requires explicit human approval before enabling them.

// WHY ENFORCE A POLICY ON SIMULATOR_KEYCHAIN

Without a policy, an AI agent could call simulator_keychain in a loop, permanently destroying resources in Preflight Ios. There is no undo for destructive operations. Intercept blocks this tool by default and only allows it when a human explicitly approves the action.

// RECOMMENDED POLICY

Destructive tools permanently remove data. Block by default. Only enable with explicit approval workflows.

  simulator_keychain:
    rules:

// FAQ

What does the simulator_keychain tool do? +

Manipulate the device keychain: add root certificates, add certificates, or reset the entire keychain.. It is categorised as a Destructive tool in the Preflight Ios MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.

How do I enforce a policy on simulator_keychain? +

Add a rule in your Intercept YAML policy under the tools section for simulator_keychain. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Preflight Ios MCP server.

What risk level is simulator_keychain? +

simulator_keychain is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.

Can I rate-limit simulator_keychain? +

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

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

simulator_keychain is provided by the Preflight Ios MCP server (preflight-ios-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
