AI agents call gov.bea-gdp to retrieve information from Mcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a data retrieval operation with no side effects. It queries an authoritative public database (BEA) and returns economic statistics. The parameters (state, year) are filters only; they do not trigger actions, execute code, or modify any data.
From the tool's definition Tool retrieves quarterly real GDP data from BEA Regional accounts; explicitly described as 'Returns the state name + GDP observations'. No modification, deletion, execution, or financial transaction occurs. Data is public-domain and read-only.

Quarterly real GDP by US state from the Bureau of Economic Analysis (BEA) Regional accounts — all-industry total, in millions of chained (inflation-adjusted) dollars. Requires state (2-letter); optional year (defaults to last 5 years). Returns the state name + GDP observations (period like 2025Q2, real GDP millions USD, unit), newest quarter first. Free, public-domain (BEA). Authoritative state economic-output data an LLM cannot recall. It is categorised as a Read tool in the Mcp MCP Server, which means it retrieves data without modifying state.
Register the MCP server in PolicyLayer and add a rule for gov.bea-gdp: 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 Mcp. Nothing to install.
gov.bea-gdp 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 gov.bea-gdp 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 gov.bea-gdp. 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.
gov.bea-gdp is provided by the MCP server (@2sio/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
