When deciding the position to add a new object to the path, this rectangular area should be avoid.

AI agents call get_avoid_rect_position to retrieve information from MaxMSP-MCP-Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries the current state of a Max patch to determine spatial positioning information. It has no side effects—it only reads and returns coordinate data to help avoid overlapping when adding objects. There is no data modification, code execution, or resource consumption beyond data retrieval.
From the tool's definition Tool description states it 'Returns: list: A list of four numbers representing the left, top, right, bottom of the rectangular area.' This is a pure query operation that retrieves layout metadata about existing objects in a Max patch without modifying any…
Documented attack patterns abuse exactly the kind of access get_avoid_rect_position gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MaxMSP-MCP-Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_avoid_rect_position:
{
"version": "1",
"default": "deny",
"tools": {
"get_avoid_rect_position": {}
}
}get_avoid_rect_position is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

When deciding the position to add a new object to the path, this rectangular area should be avoid. This is useful when you want to add an object to the patch without overlapping with existing objects. Returns: list: A list of four numbers representing the left, top, right, bottom of the rectangular area. It is categorised as a Read tool in the MaxMSP-MCP-Server MCP Server, which means it retrieves data without modifying state.
Register the MaxMSP-MCP-Server MCP server in PolicyLayer and add a rule for get_avoid_rect_position: 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 MaxMSP-MCP-Server. Nothing to install.
get_avoid_rect_position is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_avoid_rect_position 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 get_avoid_rect_position. 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.
get_avoid_rect_position is provided by the MaxMSP-MCP-Server MCP server (tiianhk/maxmsp-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
