Real-time risk-weighted USDC lending APY across 6 protocols on Base, paid via x402
Real-time risk-weighted USDC lending APY across 6 protocols on Base, paid via x402. Exposed over MCP by the yieldsignal mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.
Risk-weighted yield signals for autonomous agents, paid per call via the x402 protocol — no API key, no signup. First 3 calls/day per IP are free via ?trial=1.
Everything the assistant can do here goes through one of these:
score — directional: was the flagged protocol still the leader (or within 25bps) when scored against the market right nowwindowedScore — each attestation judged over its own validity window, i.e. until the next attestation for that asset replaced it. medianWindowHours is theYou will need 2 environment variables: CDP_API_KEY_ID, WALLET_SECRET. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Installation goes through your MCP client rather than a global install: point it at npm on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. YieldSignal's toolset — score, windowedScore — is a fair guide to whether it matches your workflow. It is maintained by Stakemate369; worth a glance at recent repository activity before you build anything load-bearing on it.

| windowedScore | each attestation judged over **its own validity window**, i.e. until the next attestation for that asset replaced it. medianWindowHours is the practical answer to "how often should I re-check?" and it differs sharply per |
