Retrieves only the items stored in a container
AI agents call get_container_contents_only to retrieve information from RSpace MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a simple data retrieval operation. It queries the contents of a container in RSpace but does not create, modify, delete, or execute any operations. The verb 'Retrieves' and the absence of any side effects clearly place this in the Read category. The blast radius is minimal since it only accesses existing data without making changes.
From the tool's definition The tool 'get_container_contents_only' with description 'Retrieves only the items stored in a container' is a read-only operation that queries and returns data without modifying, deleting, or executing any operations.
Attacks that exploit this kind of access
Retrieves only the items stored in a container. It is categorised as a Read tool in the RSpace MCP Server MCP Server, which means it retrieves data without modifying state.
Register the RSpace MCP Server MCP server in PolicyLayer and add a rule for get_container_contents_only: 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 RSpace MCP Server. Nothing to install.
get_container_contents_only 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_container_contents_only 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_container_contents_only. 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_container_contents_only is provided by the RSpace MCP Server MCP server (rspace-os/rspace-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
