What fed_z1_catalog does on Livedatalink
AI agents call fed_z1_catalog to retrieve information from Livedatalink without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
limit | integer | — | Maximum series. Default 20. |
query | string | — | Optional substring of slug, official series ID, or title. |
offset | integer | — | Series to skip. Default 0. |
category | string | — | Optional curated category. |
response_format | string | — | Human-readable markdown or machine-readable JSON. Default markdown. |
Parameters from the server's own tool schema.
Why fed_z1_catalog is rated Low
Even though fed_z1_catalog only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
The rule that runs fed_z1_catalog safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Livedatalink, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For fed_z1_catalog, this is the rule to start with:
fed_z1_catalog is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Livedatalink, apply this rule, and every fed_z1_catalog call is checked against it from then on.
Questions about fed_z1_catalog
List and search the deliberately small catalog of aggregate U.S. balance-sheet and debt series in LiveDataLink's self-hosted Federal Reserve Z.1 snapshot. Returns official series IDs, stable LiveDataLink slugs, table/line metadata, units, adjustment basis, coverage, pagination, release hash, and attribution. Use this for 'what household balance-sheet measures are available?', 'find the mortgage debt series', or to resolve a series before another Z.1 call. This is not the full Z.1 universe. It is categorised as a Read tool in the Livedatalink MCP Server, which means it retrieves data without modifying state.
fed_z1_catalog accepts 5 parameters: limit, query, offset, category, response_format. The full parameter table on this page comes from the server's own tool schema.
Register the Livedatalink MCP server in PolicyLayer and add a rule for fed_z1_catalog: 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 Livedatalink. Nothing to install.
fed_z1_catalog 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 fed_z1_catalog 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 fed_z1_catalog. 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.
fed_z1_catalog is provided by the Livedatalink MCP server (https://livedatalink.ai/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
