What fed_board_h15_yield_curve does on Livedatalink
AI agents invoke fed_board_h15_yield_curve to trigger actions in Livedatalink. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
| Parameter | Type | Required | Description |
|---|---|---|---|
date | string | — | ISO date YYYY-MM-DD. |
response_format | string | — | Human-readable markdown or machine-readable JSON. Default markdown. |
Parameters from the server's own tool schema.
Why fed_board_h15_yield_curve is rated High
fed_board_h15_yield_curve triggers real processes with real consequences. An agent gone sideways doesn't fire it once. It starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.
Attacks that exploit this kind of access
The rule that runs fed_board_h15_yield_curve 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_board_h15_yield_curve, this is the rule to start with:
fed_board_h15_yield_curve stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. 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_board_h15_yield_curve call is checked against it from then on.
Questions about fed_board_h15_yield_curve
Build the nominal US Treasury constant-maturity yield curve from the Federal Reserve Board's self-hosted H.15 snapshot for the latest business day on or before a date. Returns maturities, yields, canonical series names, 10y-2y and 10y-3m spreads, curve-shape classification, provenance, and source hash. Use this for 'show today's Treasury curve', 'was the curve inverted on 2024-06-03?', or 'compare short and long rates'. Not security pricing or investment advice. It is categorised as a Execute tool in the Livedatalink MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
fed_board_h15_yield_curve accepts 2 parameters: date, 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_board_h15_yield_curve: 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_board_h15_yield_curve is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the fed_board_h15_yield_curve 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_board_h15_yield_curve. 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_board_h15_yield_curve 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.
