Nothing to run from here
Stablecoin Yield 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.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
Claude Codedeclared by this listing
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http stablecoin-yield-mcp https://mcp.barker.money/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
What you approve
11 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

| Parameter | Type | Required | Notes |

Fuzzy search Barker's pool index by keyword (protocol name / pool name / asset). Resolves natural-language pool references to pool_uid for the detail/history tools. (paid: $0.001 per call via x402)
| Parameter | Type | Required | Notes |
|---|---|---|---|

EXECUTION DISCOVERY: which stablecoin vaults in Barker's index support direct deposit/redeem through barker_execution_quote. Returns executable pools with adapter support, live deposit capacity (is_full) and APY/TVL. Call this before barker_execution_quote — every pool listed here can be quoted, and its pool_uid is the exact string that tool expects (its vault_token_address works there too). Skip
| Parameter | Type | Required | Notes |
|---|---|---|---|
| asset | string | no | Optional stablecoin symbol filter, case-insensitive: usdc, usdt. Omit to list all assets. |
| chain | string | no | Optional chain filter (lowercase), e.g. base, ethereum |
| query | string | no | Optional pool keyword, e.g. 'Steakhouse USDC' |
| action | string | no | Filter by executable action |
| limit | integer | no | Max rows (default 20) |
| min_tvl | number | no | Min TVL floor in USD (default 1000000) |
EXECUTION QUOTE (non-custodial): buy an unsigned, ready-to-sign transaction that deposits into or redeems from a stablecoin vault. Returns transaction_request {chainId,from,to,data,value} + route + risk summary + approval info. Barker NEVER broadcasts and never holds funds — return the transaction to YOUR user's wallet to sign; vault shares always go to signer_address (receiver is not a parameter)
| Parameter | Type | Required | Notes |
|---|---|---|---|
| pool_uid | string | yes | Either the exact pool_uid from barker_executable_pools (copy verbatim), OR the vault contract address (0x + 40 hex) if that is what you already have — no discovery call needed. Both are matched exactl |
| chain_id | integer | no | Optional, only useful when pool_uid is a contract address that is deployed at the same address on several chains (e.g. Aave aTokens). EVM chain id, e.g. 8453 for Base. |
| action | string | no | Default deposit |
| amount_base_units | string | yes | Integer amount in token base units (1 USDC = 1000000). For redeem: underlying assets to withdraw. Send either this OR amount — not both (they are cross-checked and a mismatch is rejected). |
| amount | string | no | Same amount in human units ("1000" = 1000 USDC), converted server-side using the pool's own asset decimals. Use this if you don't want to compute base units yourself. Alternative to amount_base_units. |
| signer_address | string | yes | EVM address that will sign AND receive vault shares / redeemed assets. Mandatory — it is the tx sender and the share recipient, so Barker can never infer or default it. |
| slippage | number | no | Optional slippage tolerance, e.g. 0.005 |
VAULT POSITION (on-chain read): current redeemable value of a wallet's ERC-4626 vault position. Pass the pool_uid (from barker_executable_pools / barker_execution_quote) and the wallet address; Barker resolves the vault contract and reads balanceOf + convertToAssets directly on-chain, returning shares and current_value in the vault's underlying asset (value_asset, e.g. USDC). Barker does not store
| Parameter | Type | Required | Notes |
|---|---|---|---|
| address | string | yes | EVM wallet address holding the vault shares (0x + 40 hex) |
| pool_uid | string | yes | Barker pool uid of the ERC-4626 vault, e.g. morpho-vault_base_usdc_0xee8f4ec5 (from barker_executable_pools) |

No rule-by-rule report on file for this release
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.
This listing is an address its publisher runs, and you connect to it directly — this marketplace is not in the path. The scanner reads packages and public source, and an address is neither: the repository linked on this page is where this record was collected from, not a copy of what the address serves, so it is not graded in its place. So there is no grade — not a withheld one, an unmeasured one.
Release history
This is an address its publisher runs: which release it serves is theirs to choose, so there is nothing here to pin. The history below is for reading; the current release on file is 1.0.4.

Who can review
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 Stablecoin Yield can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
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.
