AI agents call yield_curve_v2 to retrieve information from Feedoracle Macro Mcp without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though yield_curve_v2 only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

These attack patterns abuse exactly the kind of access yield_curve_v2 gives an agent. Each links to the full case and the policy that stops it:
Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
[AGENT-NATIVE v2] Treasury 10Y-2Y spread WITH interpretation layer: curve_state (deep_inverted/inverted/flat/normal/steep), days_inverted_last_365, recession_imminent detection (un-inversion pattern), ranked actions array.. It is categorised as a Read tool in the Feedoracle Macro Mcp MCP Server, which means it retrieves data without modifying state.
Register the Feedoracle Macro MCP server in PolicyLayer and add a rule for yield_curve_v2: 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 Feedoracle Macro Mcp. Nothing to install.
yield_curve_v2 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 yield_curve_v2 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 yield_curve_v2. 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.
yield_curve_v2 is provided by the Feedoracle Macro MCP server (https://feedoracle.io/mcp/macro/sse). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
