Return a stable hash signature of the cached dataset (useful for reproducible forecasts).
AI agents call ram_get_dataset_signature to retrieve information from RAM Prices MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves a computed value (a hash signature) from already-cached data. It has no side effects, does not execute external code, does not modify data, and does not move money. The hash is read-only metadata useful for verification. The purpose explicitly states it is for 'reproducible forecasts', confirming passive information retrieval.
From the tool's definition Tool returns a hash signature of cached data ("Return a stable hash signature of the cached dataset") with no modification, creation, deletion, or external operation described.
Attacks that exploit this kind of access
Return a stable hash signature of the cached dataset (useful for reproducible forecasts). It is categorised as a Read tool in the RAM Prices MCP Server MCP Server, which means it retrieves data without modifying state.
Register the RAM Prices MCP Server MCP server in PolicyLayer and add a rule for ram_get_dataset_signature: 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 RAM Prices MCP Server. Nothing to install.
ram_get_dataset_signature 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 ram_get_dataset_signature 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 ram_get_dataset_signature. 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.
ram_get_dataset_signature is provided by the RAM Prices MCP Server MCP server (xeonvs/ddr-price-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
