api record

Risk-adjusted DeFi yield recommendations powered by DeFiLlama. Use get_best_yield to find the optimal yield for a given asset and risk profile. Use explain_risk to understand why a protocol is rated as it is. Use compare_yields to compare multiple protocols side-by-side. All outputs are optimized for minimal token consumption.

_ is it live, free and safe measured by this hub
Is defi-yield-engine live?
Yes — it answered the hub's last check (checked 13h ago). It answered 99% of checks over the last 30 days.
Is defi-yield-engine free to use?
Yes — the hub reached it with no key and no payment.
What tools does defi-yield-engine have?
17 tools: explain_risk, compare_yields, yield_alert_set, yield_alert_delete, score_contract, get_optimal_allocation, yield_alert_check, compare_perps, ….
Is defi-yield-engine safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • get_gas_price reads open 3d ago

    Get current gas prices across urgency levels for a given chain. FREE. Returns safe/standard/fast gas prices in Gwei with USD cost estimate for a standard ERC-20 transfer (21,000 gas). Use this when: an agent needs current gas cost before executing a transaction. Follow with get_optimal_gas_window to decide whether to wait.

  • get_optimal_gas_window reads open 3d ago

    Predict the best time window to execute transactions for minimum gas cost. Uses historical Ethereum gas patterns (hourly + day-of-week multipliers) to identify upcoming low-gas windows. Typical savings: 25-45% vs peak hours. Best windows: 3-7 AM UTC (daily low) and weekends (-20 to -25%). Use this when: an agent can defer a non-urgent transaction to save on gas. Combine with get_gas_price for current baseline.

  • score_contract reads unknown never probed

    Score a smart contract for security risks using GoPlus Security API. Checks for: honeypot detection, buy/sell tax, ownership risks, proxy patterns, trading cooldowns, blacklist functions, mint capabilities, and liquidity risks. Risk score 0-100 (100 = safest). Covers tokens and general contracts. Use this when: an agent is about to interact with an unknown contract or token. Do NOT use for: known safe protocols (use explain_risk for Aave/Morpho/etc.).

  • get_optimal_allocation reads unknown 4d ago

    Split capital optimally across multiple DeFi protocols for maximum risk-adjusted yield. Unlike get_best_yield (one protocol), this tool returns a weighted multi-protocol allocation that maximizes APY while respecting TVL constraints and risk limits. Ideal for amounts >$10,000 where diversification improves risk-adjusted returns. Use this when: an agent needs to deploy capital across multiple protocols. Do NOT use for: single-protocol analysis (use get_best_yield or explain_risk).

  • get_best_yield reads unknown 3d ago

    Select the single best DeFi yield opportunity for a given asset and risk profile. Scores 13,800+ pools across 548 protocols and 115 chains using a 9-signal risk algorithm (TVL, APY stability, reward dependency, outlier flag, momentum). Returns ONE opinionated recommendation with reasoning + 2 alternatives. Output: ~60 tokens — 97% smaller than raw DeFiLlama data. Use this when: an agent needs to deploy capital and wants a single actionable answer, not a list to evaluate manually. Do NOT use for: protocol comparison (use compare_yields), risk detail (use explain_risk).

_ try it over mcp through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 0c782e75f2aa9976.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/0c782e75f2aa9976/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
