AI agents call inflation_adjust 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 performs a read-only transformation: it queries or retrieves CPI-U inflation index data and applies a mathematical formula to adjust nominal dollar amounts to real terms. It has no side effects, does not create, modify, or delete any data, and does not execute arbitrary code or trigger external operations.
From the tool's definition Tool name 'inflation_adjust' and description indicate it 'Convert[s] dollar amounts between dates using CPI-U', a pure data transformation operation that retrieves and applies existing economic data (CPI-U index values) to perform calculations.
Attacks that exploit this kind of access
Convert dollar amounts between dates using CPI-U. Use for:. 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 inflation_adjust: 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.
inflation_adjust 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 inflation_adjust 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 inflation_adjust. 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.
inflation_adjust 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.
