How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security83
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability62

check_pool Check one liquidity pool ~679
Use this when the user asks about one real liquidity pool, such as "volume and fee APR for WETH and USDC on Ethereum" or "is this pool APR a spike?". Pass pool_id (a DefiLlama UUID), or chain plus token_a and token_b, for example chain "ethereum", token_a "WETH", token_b "USDC". Do not try pool_address first: the open index has no pool contract addresses, so it always returns needs_tokens. Returns 1-day and 7-day volume and fee APR, TVL, an APR flag with a reason, a risk checklist with warnings, price trend, token risk flags when a public source covers them, and an informational position-type label. Symbols for one token pair with several fee tiers or exchanges return the highest-TVL pool, with the others in other_tiers. Symbols that match different tokens return status ambiguous. The optional range fields (price_lower, price_upper, price_now, holding_days, capital_usd, gas_usd, exit_cost_usd) add the same fee-versus-impermanent-loss estimate as estimate_lp, at this pool's fee APR. For a pure what-if with no pool, use estimate_lp.
| Name | Type | Req | Description |
|---|---|---|---|
| capital_usd | number | – | Position size, so gas and exit cost can be compared with fees. Not stored as a record of who asked |
| chain | string | – | Chain name or short alias, used with token_a and token_b: ethereum, base, arbitrum, optimism, polygon, bsc, avalanche, solana, zksync, linea, gnosis, scroll, mantle, celo, sonic, or sui. Aliases such… |
| exit_cost_usd | number | – | Other exit cost, such as a withdrawal fee, in the same currency as capital_usd |
| gas_usd | number | – | Gas you expect to pay to enter and exit, in the same currency as capital_usd |
| holding_days | integer | – | Holding window for the fee-versus-IL estimate. Requires price_lower, price_upper, and price_now |
| pool_address | string | – | Pool contract address. The open yields index has no pool contract addresses, so this always returns needs_tokens. Prefer pool_id, or chain with token_a and token_b |
| pool_id | string | – | DefiLlama pool id, a UUID such as "b99bcdf5-1350-4269-981e-0e9b5cccb007", from find_active_pools or other_tiers. Send it alone |
| price_lower | number | – | Lower price of the range, in quote per base |

estimate_lp Estimate fees versus impermanent loss ~418
Estimate fees versus impermanent loss. Use this when the user gives numbers for a what-if and wants to know whether swap fees cover impermanent loss, gas, and exit cost. It needs no pool and reads no live data. Pass price_now, holding_days, and fee_apr_percent, for example price_now 2500, holding_days 14, fee_apr_percent 40. Add price_lower and price_upper for a concentrated range, or omit both for the full-range formula. Optionally pass price_later, capital_usd, gas_usd, and exit_cost_usd. Returns the formula, the fee fraction, the impermanent loss fraction, whether fees cover it and the costs you passed, a plain break-even price line, and break-even prices from a sample. It does not look up gas or recommend a position. To read a real pool's volume and fee APR, use check_pool.
| Name | Type | Req | Description |
|---|---|---|---|
| capital_usd | number | – | Position size, so gas and exit cost can be turned into a fraction of the position |
| exit_cost_usd | number | – | Other exit cost. Not looked up |
| fee_apr_percent | number | yes | Annualized fee APR in percent, not a fraction: 40 means 40%. For example the 1-day fee APR from check_pool |
| gas_usd | number | – | Gas you expect to pay. Not looked up |
| holding_days | integer | yes | How many days the fee APR is applied, a whole number from 1 to 365, such as 14 |
| price_later | number | – | A later price to score. Omit to get break-even prices and the range edges only |
| price_lower | number | – | Lower bound of a concentrated range. Omit, with price_upper, for the full-range formula |
| price_now | number | yes | Current price, quote token per base token, such as 2500 for ETH in USDC |
| price_upper | number | – | Upper bound of a concentrated range |
| Name | Type | Req | Description |
|---|---|---|---|
| assumptions | array | yes | – |
| break_even_line | string | – | – |

find_active_pools Find pools with volume and fees ~371
Use this when the user wants pools across chains or DEXes with recent volume and a fee rate, such as "high fee pools on Base with real volume". All arguments are optional: chains, min_volume_usd_1d (default 50000), min_fee_percent (default 0.05), and limit (default 5, at most 8). Returns each pool's id, volume, TVL, fee rate, 1-day and 7-day fee APR, and an APR flag with its reason, highest 1-day fee APR first. A small pool with a one-day volume spike can rank first, so check tvl_usd and apr_flag before you lead with it, or raise min_volume_usd_1d. It does not read token contracts or the current tick. Call check_pool with a returned pool_id for token flags and the risk checklist.
| Name | Type | Req | Description |
|---|---|---|---|
| chains | array | – | Optional chain names, such as ["base"] or ["ethereum", "arbitrum"]. Supported: ethereum, base, arbitrum, optimism, polygon, bsc, avalanche, solana, zksync, linea, gnosis, scroll, mantle, celo, sonic,… |
| limit | integer | – | How many pools to return, at most 8. Default 5 |
| min_fee_percent | number | – | Minimum swap fee in percent, not a fraction: 0.3 means 0.3%. Read from pool metadata. Default 0.05 |
| min_volume_usd_1d | number | – | Minimum 1-day volume in USD. Default 50000. Raise it, for example to 1000000, to skip small pools with a one-day spike |
| Name | Type | Req | Description |
|---|---|---|---|
| as_of | string|null | yes | ISO 8601 UTC time of the yields index read, or null when nothing was read |
