Change how the operator interface presents information. Use this when the situation calls for a denser HUD, a minimal compact view, spoken output only, or silence. Returns a JSON confirmation with the new mode and timestamp.
AI agents use sint__interface_mode to create or update resources in SINT Protocol — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your SINT Protocol environment.
This tool modifies the display/presentation mode of the operator interface (HUD, compact view, spoken output, silence). It is a reversible configuration change with no data destruction, financial impact, or code execution. The blast radius is low since it only affects how information is presented to the operator, not underlying data or security policies.

Documented attack patterns abuse exactly the kind of access sint__interface_mode gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and SINT Protocol, and nothing reaches the server without passing your rules. This is the rule we recommend for sint__interface_mode:
{
"version": "1",
"default": "deny",
"tools": {
"sint__interface_mode": {
"limits": [
{
"counter": "sint__interface_mode_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}sint__interface_mode stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Change how the operator interface presents information. Use this when the situation calls for a denser HUD, a minimal compact view, spoken output only, or silence. Returns a JSON confirmation with the new mode and timestamp. It is categorised as a Write tool in the SINT Protocol MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the SINT Protocol MCP server in PolicyLayer and add a rule for sint__interface_mode: 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 SINT Protocol. Nothing to install.
sint__interface_mode 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 sint__interface_mode 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 sint__interface_mode. 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.
sint__interface_mode is provided by the SINT Protocol MCP server (sint-ai/sint-protocol). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from SINT Protocol, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
