Available tools 2

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

yield

get_yield_decision

Buyer-side MOVE/HOLD decision (Layer 1 premium — sells the decision, not the raw datapoint). Given your current position, size, move cost and horizon, returns whether moving your capital to the best risk-adjusted protocol pays for itself now — with expected net gain, break-even days and a confidence tier. Deterministic from the underlying signal, which is EIP-712 signed and returned in a sibling content block (re-run the decision locally to reproduce it). Priced above the plain signal tool.

get_yield_signal

Real-time risk-weighted yield signal. USDC/WETH: lending APY on Base (Aave/Compound/Morpho read onchain, Moonwell/Euler/Fluid via DefiLlama). ETH_STAKING: liquid staking APY on Ethereum mainnet (Lido/Rocket Pool/Coinbase Wrapped Staked ETH/Frax Ether/Binance Staked ETH, all via DefiLlama) — a different chain and category from the lending signals, not a Base lending market. Source tagged per reading (never estimated). Result is signed (EIP-712 typed data) by the payment-receiving address, returned as a sibling content block for offline verification. That same address is registered on-chain as an ERC-8004 agent identity (agent-card.json) and periodically publishes EAS attestations of past readings (Base mainnet) — a public track record independent of this server's uptime.

YieldSignal — questions

Answers built from our own checks of this server.

What can YieldSignal do?

It exposes 2 tools, read directly from the server on our last check. Among them: get_yield_decision, get_yield_signal. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is YieldSignal working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 255 ms. The bar chart above shows every period we have measured.

How do I connect YieldSignal?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does YieldSignal need an API key?

No. YieldSignal completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is YieldSignal?

It answers our handshake in 255 ms on average, which is faster than 53% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is YieldSignal open source?

Yes — it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
