WHAT IT DOES

What get_lending_yields does on Tanod

AI agents call get_lending_yields to retrieve information from Tanod 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
`view`	string	—	all: every matching rate, highest supply APY first. best_stablecoin: USDC, USDT, DAI, USDS and USDe ranked by supply APY across the three protocols (canonical t
`limit`	integer	—	Rows returned, 1-200 (default 50).
`assets`	object	—	Optional asset symbols such as USDC or WETH (case-insensitive, at most 20). In best_stablecoin only USDC, USDT, DAI, USDS and USDe are ranked.
`chains`	object	—	Optional subset of ethereum, base, arbitrum, polygon, optimism. Default: all. Aave V3, Compound V3 and Morpho cover all five.
`protocols`	object	—	Optional subset of aave_v3, compound_v3, morpho. Default: all.
`min_tvl_usd`	object	—	Only rows with at least this many USD supplied (rows with an unknown USD size are dropped when it is above 0). Default 0; best_stablecoin defaults to 1,000,000.

Parameters from the server's own tool schema.

RISK

Why get_lending_yields is rated Low

Even though get_lending_yields 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.

RECOMMENDED RULE

The rule that runs get_lending_yields safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Tanod, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get_lending_yields, this is the rule to start with:

get_lending_yields Allowed

get_lending_yields is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_lending_yields": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Tanod, apply this rule, and every get_lending_yields call is checked against it from then on.

FAQ

Questions about get_lending_yields

What does the get_lending_yields tool do? +

chainpeek: Use when an agent must choose where to lend or borrow: supply and borrow APY on Aave, Compound and Morpho. For protocol TVL use get_protocol_tvl; for perp funding use get_funding_rates. Returns current lending supply and borrow APY on Aave V3, Compound V3 and Morpho by chain and asset, or the best stablecoin supply rate (USDC, USDT, DAI, USDS, USDe) across them. Snapshot refreshed about every 5 minutes (as_of, stale); Aave, Compound and Morpho on Ethereum, Base, Arbitrum, Optimism and Polygon; APY excludes rewards. Informational only, not investment advice. Bad input is a 422 (not charged). Typically under 1 s. Price: USD 0.001. Free: 10 chain reads per IP per UTC day. Docs: https://tanod.dev/learn/defi-lending-rates-api.html. It is categorised as a Read tool in the Tanod MCP Server, which means it retrieves data without modifying state.

What parameters does get_lending_yields accept? +

get_lending_yields accepts 6 parameters: view, limit, assets, chains, protocols, min_tvl_usd. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on get_lending_yields? +

Can I rate-limit get_lending_yields? +

Yes. Add a rate_limit block to the get_lending_yields 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.

How do I block get_lending_yields completely? +

Set action: deny in the PolicyLayer policy for get_lending_yields. 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.

What MCP server provides get_lending_yields? +
