List objects from your Cosmic bucket. Optionally filter by object type, with pagination support.
AI agents call list_objects 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 retrieves and queries data from a CMS bucket without side effects. It supports read-only operations (listing, filtering, pagination) typical of data retrieval. The severity is low because misuse would only expose or enumerate existing data within the bucket, not modify or delete it.
From the tool's definition Tool name 'list_objects' and description 'List objects from your Cosmic bucket' indicate a retrieval operation with optional filtering and pagination. No modification, deletion, or execution capability is described.
Attacks that exploit this kind of access
List objects from your Cosmic bucket. Optionally filter by object type, with pagination support. 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_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 Cosmic MCP Server. Nothing to install.
list_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_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_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_objects 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.
