What ecb-rates.macro.yield_curve does on Apibase
AI agents call ecb-rates.macro.yield_curve to retrieve information from Apibase 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 |
|---|---|---|---|
end_period | string | — | End of date range: YYYY, YYYY-MM, or YYYY-MM-DD depending on series frequency. Ignored if last_n_observations is set. |
tenor_years | string | — | Bond maturity in years for the spot rate: "1", "5", "10", or "30". Default "10". |
start_period | string | — | Start of date range: YYYY, YYYY-MM, or YYYY-MM-DD depending on series frequency. Ignored if last_n_observations is set. |
last_n_observations | integer | — | Return only the most recent N observations (max 100). Takes precedence over start_period/end_period. Default 10 if no range given. |

Attacks that exploit this kind of access
The rule that runs ecb-rates.macro.yield_curve safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Apibase, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For ecb-rates.macro.yield_curve, this is the rule to start with:
ecb-rates.macro.yield_curve 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 Apibase, apply this rule, and every ecb-rates.macro.yield_curve call is checked against it from then on.
Questions about ecb-rates.macro.yield_curve
Get the euro area AAA-rated government bond spot yield curve rate for a given maturity (1, 5, 10, or 30 years). Business-day series used as a euro area risk-free benchmark. Filter by tenor_years, and either last_n_observations or start_period/end_period. Data: ECB Statistical Data Warehouse (data-api.ecb.europa.eu), no auth required. It is categorised as a Read tool in the Apibase MCP Server, which means it retrieves data without modifying state.
ecb-rates.macro.yield_curve accepts 4 parameters: end_period, tenor_years, start_period, last_n_observations. The full parameter table on this page comes from the server's own tool schema.
Register the Apibase MCP server in PolicyLayer and add a rule for ecb-rates.macro.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 Apibase. Nothing to install.
ecb-rates.macro.yield_curve 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 ecb-rates.macro.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 ecb-rates.macro.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.
ecb-rates.macro.yield_curve is provided by the Apibase MCP server (apibase-mcp-client). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
