How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security49
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 12 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability66
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 2280 tokens (~190/item across 12 items; 12 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage96
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 87% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 12 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 12 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

barker_crosschain_routes ~85
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)
| Name | Type | Req | Description |
|---|---|---|---|
| from_chain | string | yes | Origin chain (lowercase) |
| symbol | string | yes | Stablecoin symbol (lowercase) |
No output schema declared.
No examples provided.
barker_defi_vaults ~225
Query real-time stablecoin supply yield pools from Barker's index of 500+ DeFi protocols. Returns ranked rows with protocol_name, chain_name, asset_symbol, supply_apy_total (decimal — multiply by 100 for %), and supply_tvl (USD). Use for questions like 'best stablecoin yield', 'where to earn on USDC', 'compare lending rates', '稳定币利率'. (paid: $0.001 per call via x402)
| Name | Type | Req | Description |
|---|---|---|---|
| asset | string | – | Stablecoin symbol (lowercase): usdt, usdc, dai, usde, usds, fdusd, gho, crvusd, pyusd, sdai, frxusd, tusd, lusd, dola, etc. |
| chain | string | – | Chain name (lowercase): ethereum, bsc, arbitrum, base, polygon, optimism, avalanche, solana, etc. |
| limit | integer | – | Row count (default 50, max 100) |
| sort | string | – | Sort key |
No output schema declared.
No examples provided.
barker_executable_pools ~287
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)
| Name | Type | Req | Description |
|---|---|---|---|
| action | string | – | Filter by executable action |
| asset | string | – | Optional stablecoin symbol filter, case-insensitive: usdc, usdt. Omit to list all assets. |
| chain | string | – | Optional chain filter (lowercase), e.g. base, ethereum |
| limit | integer | – | Max rows (default 20) |
| min_tvl | number | – | Min TVL floor in USD (default 1000000) |
| query | string | – | Optional pool keyword, e.g. 'Steakhouse USDC' |
No output schema declared.
No examples provided.
barker_execution_quote ~592
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)
| Name | Type | Req | Description |
|---|---|---|---|
| action | string | – | Default deposit |
| amount | string | – | 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. |
| 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). |
| chain_id | integer | – | 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. |
| 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 exact… |
| 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 | – | Optional slippage tolerance, e.g. 0.005 |
No output schema declared.
No examples provided.
barker_market_overview ~81
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)
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
barker_market_trend ~94
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)
| Name | Type | Req | Description |

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)
| Name | Type | Req | Description |
|---|---|---|---|
| budget | number | – | USDC loss budget; default 5 × margin |
| leverage | integer | – | – |
| margin | number | – | USDC margin per leg; enables the estimate |
| market | string | – | BTC or ETH; omit for all |
| stop_pct | number | – | stop-loss distance in %, e.g. 0.3 |

| Name | Type | Req | Description |
|---|---|---|---|
| keyword | string | yes | – |
| limit | integer | – | – |
No output schema declared.
No examples provided.
barker_vault_position ~236
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)
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | yes | EVM wallet address holding the vault shares (0x + 40 hex) |

| Name | Type | Req | Description |
|---|---|---|---|
| asset | string | – | Stablecoin symbol (lowercase): usdt, usdc, dai, usde, ... |
| chain | string | – | Optional chain filter (lowercase) |
| limit | integer | – | Top-N picks (default 5) |
| min_tvl | number | – | Optional explicit TVL floor (USD) |
| risk | string | – | Risk band → TVL floor $10M/$1M/$100K |
