Get the complete contents of a specific dataset
AI agents call get_dataset to retrieve information from Opera Omnia 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 returns dataset contents with no side effects, matching the Read category definition (retrieves or queries data; no side effects). The blast radius is minimal since it only accesses existing data. Severity is low because unauthorized read access to game/storytelling datasets poses no operational or financial risk.
From the tool's definition Tool description states 'Get the complete contents of a specific dataset' — retrieves data without modifying, deleting, or executing operations.
Attacks that exploit this kind of access
Get the complete contents of a specific dataset. It is categorised as a Read tool in the Opera Omnia MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Opera Omnia MCP Server MCP server in PolicyLayer and add a rule for get_dataset: 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 Opera Omnia MCP Server. Nothing to install.
get_dataset 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_dataset 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_dataset. 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_dataset is provided by the Opera Omnia MCP Server MCP server (triptych/opera-omnia-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
