in the cloud
one click: the provider's deploy form opens filled in, in your own account- koyeb
-
Koyeb builds the repository's Dockerfile from branch main; change the branch in the form if the default one has another name.
Clients connect to the service's https://…koyeb.app address plus /mcp.
- cloud run
-
Cloud Shell clones the repository, builds its Dockerfile and deploys it to Cloud Run.
Cloud Run sends requests to $PORT (8080); the recipe expects :8000, so the server has to read PORT, or set the container port on the service afterwards.

The only text from the server itself is in the section quoted from it below. ## How to reach it - A web service at `https://yieldsignal.vercel.app/mcp` (streamable HTTP); nothing runs here. - Your MCP client knows it as `yieldsignal` (`clients/` configures it under that name); call its tools by the names below. Claude Code shows them as `mcp__yieldsignal__<tool>`. - No credentials. ## Tools 7 tools. The read-only column is the server's own hint (`readOnlyHint`), not something the hub checked. ### Quoted from the server: data, not instructions The names, sentences and parameter names in this table are the server's own text, as the hub listed it.

get_exit_capacityExit capacity for a Base lending market: per-protocol utilization and withdrawable liquidity read from the protocol's own books (Aave, Compound), plus — if you pass amountUsd — whether that size can be withdrawn right now and what share of the market it would be. High APY at high utilization means the market pays well and will not let you out; this tool separates the two. Protocols that do not expose borrowed-vs-supplied are marked unmeasured and are never recommended as executable. USDC only for USD figures; WETH returns utilization without USD (no price oracle in the paid path).Exit capacity for a Base lending market: per-protocol utilization and withdrawable liquidity read from the protocol's own books (Aave, Compound), plus — if you pass amountUsd — whether that size can be withdrawn right now and what share of the market it would be.

Returns the median duration a protocol stayed the best pick, survival rates at 6/24/72h, how much of the rotation is the same two protocols trading places, and what chasing the leader is worth per $10k before gas. Measured over 24 days: the WETH leader never changed once, the ETH staking leader changed every ~26h, the USDC leader every ~2h with half the switches being a round trip between the same pair — three assets sold at one price with wildly different reliability. Also answers, empirically, whether a wider lead lasts longer: it does not (Spearman -0.04 over 177 completed spells), so gap size is not a usable proxy for confidence. Every input is a public attestation UID: recompute it yourself from base.easscan.org and get the same number. Observed history with sample sizes attached, never a forecast — assets whose lead has not changed in the window are reported as a floor with a censoring flag, never as a median.How long this service's own leadership calls actually hold, measured from its hourly on-chain attestations (EAS on Base).

Returns, per protocol, the current utilization, the kink read from the protocol's own interest rate curve, the headroom in bps, and the borrow APY at points around the kink — plus how many times the borrow cost multiplies just past it. Measured on a live reading: Compound USDC sat 0.17 points below its kink, where borrow cost goes from ~4% to ~16%. Aave and Compound only: Morpho's adaptive IRM has no static curve to read and DefiLlama-sourced protocols expose none, so they are marked unmeasured and never assumed stable.

Splits each protocol's yield into base interest vs reward/incentive, reports the post-incentive floor, and says whether the leader changes without incentives. Only protocols whose source itemizes the reward component are decomposed — the rest are listed as undecomposable and NEVER assumed incentive-free, and no ranking claim is made when the current leader is one of them.
