Retrieve an objects' attributes and values of the attributes. Use this to understand the state of an object. Returns: list: A list of attributes name and attributes values.
AI agents call get_object_attributes 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 purely queries and retrieves data about Max patch object state without creating, modifying, deleting, or executing operations. The retrieval of object attributes is a read-only operation with no blast radius if misused by an agent—at worst, an agent learns information about the patch, but cannot alter it.
From the tool's definition Tool name is 'get_object_attributes' and description states 'Retrieve an objects' attributes and values' with no modification or side effects indicated. Returns 'a list of attributes name and attributes values.'
Documented attack patterns abuse exactly the kind of access get_object_attributes 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_object_attributes:
{
"version": "1",
"default": "deny",
"tools": {
"get_object_attributes": {}
}
}get_object_attributes is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Retrieve an objects' attributes and values of the attributes. Use this to understand the state of an object. Returns: list: A list of attributes name and attributes values. 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_object_attributes: 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_object_attributes 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_object_attributes 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_object_attributes. 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_object_attributes 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.
