Model Context Protocol (MCP) server for freee API integration
DeFi Quant Yield & Risk Engine is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.
What it does
Quantitative DeFi carry ROE, borrow kink slippage & risk simulation across 6 protocols.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user defi-quant-yield-risk-engine-mcp '--' npx -y defi-quant-mcp-server
# 2 — ask your agent for something these tools do
# scan_stablecoin_yield_arbitrage_radar, simulate_morpho_blue_kink_slippage, simulate_ethena_susde_vesting_dilution and 4 more
DeFi Quant Yield & Risk Engine costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.
Collected from a public index. Nobody has claimed this account, so nothing here was written by its author — claim it if it is yours.
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. This one runs on your machine: your client starts DeFi Quant Yield & Risk Engine as a process under your own user, with your files and your network, so the tool surface below is what it can do to your computer rather than to a server somewhere else. Its scan result is on the Security tab — read the surface before you approve it.
This is a public server: you run it yourself and this marketplace is not in the path. You need Node.js — the current LTS (24) is the safe choice; npx comes with it. Claude Code registers it in one command; --scope user makes it available in every project. The '--' is in quotes so that PowerShell passes it on.
claude mcp add --scope user defi-quant-yield-risk-engine-mcp '--' npx -y defi-quant-mcp-serverReconnect, or start a new session, and the tools appear in the model’s tool list.
Nothing is required, but it can take RAPIDAPI_KEY (RapidAPI key for live on-chain RPC telemetry across Morpho, Ethena, Fluid, Sky, Euler V2, and Pendle V2.) if you want to set it.
One config entry your client uses to start the process locally. A local server runs with your file system and your network, which is why it is priced without metering.
7 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.
Tool surface
What the model actually sees. Descriptions are diffed on every release — see version history.
Read from its source code. A server that builds its tool list when it starts can list more tools than this.
Use this tool when a user asks where to find the best DeFi stablecoin yield, how to loop stablecoins for leveraged carry, or wants to compare Ethena sUSDe and Sky sUSDS yields against the cheapest USDC borrow rates across Morpho Blue, Fluid, and Euler V2.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| leverage | number | no | Target loop leverage multiplier (1 to 10, default: 5) |
Use this tool when a user wants to check Morpho Blue borrow rates, market utilization, or simulate how a large borrow or loop position will impact the 90% AdaptiveCurveIRM kink and push up post-trade borrow APY.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| marketId | string | no | 32-byte Morpho Blue market ID hex (defaults to flagship wstETH/USDC market) |
| simBorrowDelta | number | no | Simulated additional borrow amount in loan token units (default: 2000000) |
Use this tool when a user asks about Ethena sUSDe real-time APY, 8-hour epoch reward vesting (getUnvestedAmount), or how a large whale deposit into the sUSDe staking contract will dilute the current yield.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| simDepositUSDe | number | no | Simulated new USDe deposit size to test APY dilution (default: 25000000) |
Use this tool when a user asks about Fluid Protocol USDC borrow/supply rates, needs to decode Fluid's 256-bit BigMath storage slots (exchangePricesAndConfig), or wants to simulate post-trade utilization on Fluid.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| tokenAddress | string | no | ERC-20 token address on Fluid LiquidityLayer (defaults to Mainnet USDC) |
| simBorrowDelta | number | no | Simulated additional borrow amount in token units (default: 2000000) |
Use this tool when a user asks about Sky Protocol (MakerDAO) sUSDS savings rate, continuous per-second RAY compounding (ssr and chi), or wants to calculate leveraged sUSDS/USDC loop ROE and breakeven borrow rates on Morpho.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| leverage | number | no | Target loop leverage multiplier (default: 5) |
| borrowRateOverride | number | no | Optional manual USDC borrow APY override in percent (e.g. 6.5) |
Use this tool when a user wants to audit an Euler V2 (EVK) vault, decode uint16 compact floating-point supply/borrow caps, simulate Euler IRM borrow kink slippage, or inspect Ethereum Vault Connector (EVC) 256-bit XOR sub-account bitmaps.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| vaultAddress | string | no | Euler V2 EVault address (defaults to flagship Euler V2 Prime USDC Vault) |
| accountAddress | string | no | Optional Ethereum wallet address to scan EVC sub-account prefixes (0..3) |
| simBorrowDelta | number | no | Simulated additional borrow amount in underlying units (default: 2000000) |
Use this tool when a user asks about Pendle V2 fixed yields (PT/YT), wants to compare Spot Implied APY against the 15-minute geometric PT Oracle TWAP, or needs to simulate how a large PT trade impacts the logit AMM curve (scalarRoot, lnFeeRateRoot).
| Parameter | Type | Required | Notes |
|---|---|---|---|
| marketAddress | string | no | Pendle V2 Market contract address (defaults to flagship PT-sUSDe market) |
| simPtTradeSize | number | no | Simulated PT trade size to calculate logit curve price impact (default: 1000000) |
- Every tool, no call limit
- No card, and mcprush charges nothing for it
- Source published under MIT
- Runs on your machine — nothing of it reaches our gateway
- Nothing to cap, because mcprush bills nothing
What counts against your monthly calls
| Tool | Unit | Calls used | Out of the allowance |
|---|
Nothing here is billable: mcprush charges nothing to install DeFi Quant Yield & Risk Engine or to call it, at any volume.
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
| Term | Level | What it prices | Points |
|---|---|---|---|
| capability-exposure | minimal | capability blast radius (minimal) — client exposure if the model is manipulated | −0 |
| verification-discount | none | publisher verification (unlinked) — no provenance/repo link, but the shipped source was fully read | −2 |
| coverage-honesty | source | inspection depth (source) — how much of the target the scan could see | −0 |
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.
Tools were statically extracted from the published source (7 recovered), not enumerated from a running server. Tool-poisoning, Unicode-smuggling, capability and toxic-flow analysis ran on this inferred surface, but a mis-parsed registration could be missed or mis-attributed, so tool-derived findings are capped below “confirmed”. To grade the real runtime surface, scan the running server: --command "npx -y <package>".
Capability — what it could do if the model were manipulated
Tags derived from each tool’s schema and the implementation, not from what the tool calls itself. minimal is the level these add up to.
| Tool | Capability tags | Why the tag was assigned |
|---|---|---|
| scan_stablecoin_yield_arbitrage_radar | no tags | |
| simulate_morpho_blue_kink_slippage | no tags | |
| simulate_ethena_susde_vesting_dilution | no tags | |
| unpack_fluid_liquidity_layer_state | no tags | |
| simulate_sky_susds_leveraged_carry | no tags | |
| audit_euler_v2_vault_and_evc_subaccounts | no tags | |
| analyze_pendle_v2_logit_curve_and_twap | no tags |
Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.
The public result for this release does not print the flow graph, so there is nothing to show here. That is not the same as "no paths were found": what the scan did read is above, under coverage.
Supply chain and provenance
This is the first scan of this surface here, so there is nothing yet to compare it against.
Every result on this tab comes from one deterministic pass over the published package — offline, rule by rule, and auditable line by line above. Same methodology version, same bytes, same score.
Release history
Always latest — the install command names no version, so it installs the newest release when it runs; the current release on file is 1.0.6. Pin a release below and the command asks for exactly that one.
No release note was published with this version.
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Any signed-in account that does not publish DeFi Quant Yield & Risk Engine can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
