Fetch data direct from Bureau of Labor Statistics. Use instead of FRED when: (1) you need data on release day (BLS publishes at 8:30am ET, FRED lags 30-60 min), (2) you need metro-area CPI or state employment detail FRED doesn
AI agents call bls_get_series 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 queries public economic data from the BLS API. It performs no side effects, creates no resources, executes no code, modifies no data, and involves no financial transactions. The primary function is data retrieval, fitting squarely in the Read category with low severity and high confidence.
From the tool's definition Tool description states 'Fetch data direct from Bureau of Labor Statistics' — this is a retrieval operation with no modification, deletion, or execution capability.

Fetch data direct from Bureau of Labor Statistics. Use instead of FRED when: (1) you need data on release day (BLS publishes at 8:30am ET, FRED lags 30-60 min), (2) you need metro-area CPI or state employment detail FRED doesn. It is categorised as a Read tool in the Econstats MCP Server, which means it retrieves data without modifying state.
Register the Econstats MCP server in PolicyLayer and add a rule for bls_get_series: 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.
bls_get_series 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 bls_get_series 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 bls_get_series. 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.
bls_get_series 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.
