Returns a name list of all objects that can be added in Max. To understand a specific object in the list, use the get_object_doc tool.
AI agents call list_all_objects 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 and returns reference data (a list of available Max objects) without modifying, executing, deleting, or creating anything. It is informational only and serves to enable discovery of available objects for use with other tools. The severity is low because misuse poses minimal risk—an LLM agent obtaining a list of valid object names cannot cause harm directly.
From the tool's definition Tool name 'list_all_objects' and description 'Returns a name list of all objects that can be added in Max' indicates a pure retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access list_all_objects 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 list_all_objects:
{
"version": "1",
"default": "deny",
"tools": {
"list_all_objects": {}
}
}list_all_objects is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Returns a name list of all objects that can be added in Max. To understand a specific object in the list, use the get_object_doc tool. 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 list_all_objects: 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.
list_all_objects 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 list_all_objects 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 list_all_objects. 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.
list_all_objects 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.
