List all object types in your Cosmic bucket.
AI agents call list_object_types to retrieve information from Cosmic 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 data about object types without creating, modifying, deleting, or executing any operations. It is a straightforward read operation with no side effects, placing it in the 'Read' category with low severity.
From the tool's definition Tool name 'list_object_types' and description 'List all object types in your Cosmic bucket' indicate a retrieval operation with no modification, deletion, or execution of external commands.
Attacks that exploit this kind of access
List all object types in your Cosmic bucket. It is categorised as a Read tool in the Cosmic MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Cosmic MCP Server MCP server in PolicyLayer and add a rule for list_object_types: 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 Cosmic MCP Server. Nothing to install.
list_object_types 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_object_types 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_object_types. 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_object_types is provided by the Cosmic MCP Server MCP server (patgpt/cosmic-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
