Get metadata about a series (title, units, frequency, seasonal adjustment, notes)
AI agents call get_series_info to retrieve information from FRED MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about economic time series without modifying data, executing code, or causing side effects. It is a simple query operation that returns read-only information about series properties. The low severity reflects the minimal risk even if an AI agent calls it unexpectedly—it merely returns descriptive information about available economic data.

Register the FRED MCP Server MCP server in PolicyLayer and add a rule for get_series_info: 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 FRED MCP Server. Nothing to install.
get_series_info 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 get_series_info 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 get_series_info. 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.
get_series_info is provided by the FRED MCP Server MCP server (shawndrake2/mcp-fred). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
