AI agents call sg_gdp_history to retrieve information from Sgdata without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves historical GDP growth data for analysis purposes. It performs a read-only operation with no side effects, no code execution, and no data modification. The blast radius of misuse is minimal—at worst, an agent could request large volumes of public economic data, but no sensitive systems are at risk.
From the tool's definition Tool name 'sg_gdp_history' and description indicate retrieval of historical time series data ('Time series of YoY GDP growth'). No modification, deletion, execution, or financial transaction occurs.

Register the Sgdata MCP server in PolicyLayer and add a rule for sg_gdp_history: 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 Sgdata. Nothing to install.
sg_gdp_history 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 sg_gdp_history 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 sg_gdp_history. 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.
sg_gdp_history is provided by the Sgdata MCP server (sypherin/sgdata-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
