barker_crosschain_routesBarker's cross-chain route availability for a stablecoin from a given chain (bridge/venue coverage).No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it Barker's cross-chain route availability for a stablecoin from a given chain (bridge/venue coverage). Use for 'bridge USDC from arbitrum', '跨链路径'. (paid: $0.01 per call via x402)
barker_executable_poolsEXECUTION DISCOVERY: which stablecoin vaults in Barker's index support direct deposit/redeem through barker_execution_quote.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it 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 this call entirely if you already know the vault contract address. All parameters are optional: call with no arguments to get the top executable pools across every asset. APY unit: decimal (0.05 = 5%). Use for 'which pools can my agent actually deposit into', '哪些池子能直接存'. (paid: $0.01 per call via x402)
barker_execution_quoteEXECUTION QUOTE (non-custodial): buy an unsigned, ready-to-sign transaction that deposits into or redeems from a stablecoin vault.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it 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). Same-chain only (self/portals adapters). pool_uid takes EITHER a Barker pool_uid OR the vault contract address — if you already know the vault address, quote directly, no discovery call needed. Flow: barker_yield_advisor → barker_executable_pools → this tool → your user signs. Asset identity is resolved by the selected pool; symbols and underlying-asset token addresses are never accepted as identity (pass the VAULT contract, not the asset contract). If a pool has multiple possible underlying assets, the backend rejects ambiguity instead of guessing. Use for 'deposit 1000 USDC into this vault', '帮我把 USDC 存进这个池子(自己签名)'. (paid: $0.05 per call via x402)
barker_market_overviewBarker's stablecoin market snapshot: total market cap, yield-bearing cap, asset distribution, chain distribution.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it Barker's stablecoin market snapshot: total market cap, yield-bearing cap, asset distribution, chain distribution. Use for 'stablecoin market cap', 'USDT market share', '稳定币市场份额'. share_pct fields are decimals (0.425 = 42.5%). (paid: $0.001 per call via x402)
barker_market_trendBarker's historical APY trend for stablecoins vs.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it Barker's historical APY trend for stablecoins vs. US Treasury benchmark over a lookback window (7–180 days). Use for 'DeFi vs treasury', 'is stablecoin APY going up', 'crypto yield trend', '稳定币利率走势'. (paid: $0.001 per call via x402)
barker_paper_hedge_farmPapertrade (HyperEVM) hedge-farm snapshot: PAPER mint rate per USD lost, BTC/ETH mid prices and open-interest headroom, Barker's hosted fee and size limits.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it Papertrade (HyperEVM) hedge-farm snapshot: PAPER mint rate per USD lost, BTC/ETH mid prices and open-interest headroom, Barker's hosted fee and size limits. Pass margin (USDC per leg) with optional leverage / stop_pct / take_pct / budget to get a cost estimate (USDC per PAPER, loss and PAPER per stop). Read-only; the user starts the strategy at app.barker.money/paper. (paid: $0.001 per call via x402)
barker_pool_detailFull single-pool dossier from Barker's index by pool_uid: all APY components (percent unit), TVL, terms, execution capability, reward breakdown.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it Full single-pool dossier from Barker's index by pool_uid: all APY components (percent unit), TVL, terms, execution capability, reward breakdown. Use after barker_defi_vaults / barker_yield_advisor to inspect one pool. (paid: $0.005 per call via x402)
barker_pool_historyPer-pool APY/TVL time series from Barker's index (default 30d, APY percent unit) for trend and volatility analysis of one pool_uid.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it Per-pool APY/TVL time series from Barker's index (default 30d, APY percent unit) for trend and volatility analysis of one pool_uid. Use for 'is this pool's APY stable', '这个池子收益稳不稳'. (paid: $0.005 per call via x402)
barker_vault_positionVAULT POSITION (on-chain read): current redeemable value of a wallet's ERC-4626 vault position.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it 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 your deposit baseline — record the principal you deposited yourself; earned = current_value - your net deposits. Use after depositing via barker_execution_quote to monitor a position: 'how much is my vault position worth now', '我存进金库的 USDC 现在值多少'. (paid: $0.001 per call via x402)

Description, as the server wrote it FLAGSHIP: 'Where should I park my stablecoins right now?' Returns a ranked top-N recommendation across Barker's DeFi yield index (500+ protocols) with data-derived reasons and risk flags per pick (APY vs market median, TVL depth, incentive-dependence, lock terms). Use for 'best place for my USDC', '钱放哪收益最好', 'recommend stablecoin yield with low risk'. APY unit: percent (6.2 = 6.2%). (paid: $0.03 per call via x402)

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
