AI agents call ecb_get_data to retrieve information from Econstats without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves economic data from the European Central Bank without creating, modifying, executing, or deleting anything. It is a straightforward query/fetch operation against a public data source. The blast radius of misuse is minimal—an agent could request irrelevant data or perform unnecessary queries, but cannot harm systems or commit to financial transactions.
From the tool's definition Tool name 'ecb_get_data' and description 'Fetch ECB data' indicate data retrieval. The enumerated data types (Euro area rates, HICP inflation, money supply, exchange rates) are all read-only economic statistics with no modification or execution capability.

Register the Econstats MCP server in PolicyLayer and add a rule for ecb_get_data: 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 Econstats. Nothing to install.
ecb_get_data 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 ecb_get_data 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 ecb_get_data. 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.
ecb_get_data is provided by the Econstats MCP server (joshfwaldman1/econstats-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
