The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • hub_token_price unknown never probed

    Live price, market cap, 24h volume, price change and pool liquidity for any token on Base 8453, read from DexScreener — never from model memory. Use whenever a price or market-cap number is about to appear in your answer; quoting one from training data is always wrong by now. Triggers — "price of TOKEN", "what's X trading at", "market cap", "is it up today", "how much volume". Takes a 0x address (exact) or a ticker (resolved against Base pools, so verify the returned address is the one the user meant — tickers are not unique).

    arguments 12 lines
  • hub_wallet_holdings unknown never probed

    Every ERC-20 and native ETH balance held by a wallet on Base 8453, with live USD values, read via Moralis. Use before any portfolio answer, and before building a swap or send — it tells you what the wallet can actually spend, so you size a transaction against a real balance instead of an assumed one. Triggers — "what's in my wallet", "show my portfolio", "do I have enough USDC", "what tokens does 0x… hold", "my balance". Base 8453 only — for Robinhood Chain 4663 holdings, use blue_registry to find the rh- tools.

  • blue_registry unknown never probed

    Search the full Blue Hub catalog of 115 callable tools — 109 x402-paid and 6 free — covering on-chain data, security, DeFi, token intel and builder tooling, and get each one's id, price, category and input shape. Use when the user's request has no exact match among the tools loaded here, BEFORE telling them it cannot be done — most capabilities live in the catalog, not in this manifest. Pair it with blue_call: registry finds the id, blue_call runs it. Triggers — "what tools do you have", "can you analyse X", "is there a tool for Y", "list your capabilities", or any request you are about to decline. Covers Base 8453 and Robinhood Chain 4663; each result states its own chain. Free.

  • blue_call unknown never probed

    Execute ANY tool from the Blue Hub catalog by its id — the execution counterpart to blue_registry. Use after blue_registry returns an id you want to run. PAYMENT depends on the id, so read the price blue_registry gave you before deciding: 109 ids are x402-paid and the first call returns HTTP 402 with a `paymentRequirements` object (USDC on Base 8453, EIP-3009 transferWithAuthorization, payTo and exact amount included) — sign that authorization with your own wallet and call again with the resulting header in `payment` to get the result. The other 6 are priced $0.00 and NEVER answer 402: call them with no `payment`, no wallet and no signature, and do not wait for requirements that will not arrive. You hold your own keys — Blue Agent never sees them and never pulls funds. Triggers — any time you have a catalog id and need its output. Report a 402 to the user verbatim rather than inventing the tool's output.

  • blue_swap_tx unknown never probed

    Build an unsigned swap transaction the user signs in their OWN wallet. Base 8453 routes through 0x AllowanceHolder across Base liquidity; Robinhood Chain 4663 routes through Blue Agent's deployed RobinhoodSwapRouter against Uniswap V3 pools. Returns { to, data, value, chainId } plus any ERC-20 approval needed first — never a broadcast, never a private key. Use when the user wants to trade a token and you have both token addresses. Triggers — "swap X for Y", "buy TOKEN", "sell my TOKEN", "convert USDC to ETH". Check hub_honeypot and hub_liquidity_depth before swapping an unfamiliar token. If no route exists the response says so — do NOT invent a price.

  • blue_send_tx unknown never probed

    Build an unsigned ERC-20 or native-ETH transfer the user signs in their OWN wallet, on Base 8453 or Robinhood Chain 4663. Returns { to, data, value, chainId } with the resolved symbol, decimals and exact base-unit amount so the user can verify before signing. Non-custodial — the server encodes calldata and nothing else. Use when the user wants to move tokens to an address. Triggers — "send 50 USDC to 0x…", "transfer TOKEN to", "pay this address". Run hub_risk_gate on the recipient first when the user has not sent there before.

  • blue_bridge_tx unknown never probed

    Build an unsigned BIDIRECTIONAL bridge transaction between Base 8453 and Robinhood Chain 4663, backed by the Relay Protocol. Returns { to, data, value, chainId } plus a separate `approve` tx when the source token needs one — the user signs both in their own wallet. Use when a token or the user is on the wrong chain for what they want to do next, which is common because tokenized stocks list on both. Triggers — "bridge USDC to Robinhood", "move my ETH to Base", "get funds onto chain 4663", "I'm on the wrong network". fromChain and toChain must differ; the response carries a Relay tracker URL for the user to follow settlement.

  • b20_encode_payment unknown never probed

    Encode a B20 `transferWithMemo` call on Base 8453 — send a B20 token with an on-chain memo (order id, invoice ref) so the payment reconciles against off-chain books. Returns { to, data, value } for the sender to sign; pure calldata builder, no keys, no payment, no broadcast. Use when an agent or merchant needs a payment that carries its own reference. Triggers — "pay invoice 1234 in USDC", "send payment with order id", "settle this with a memo", "reconcilable transfer". Memo is capped at 32 UTF-8 bytes on-chain. B20 is Base-only — there is no B20 registry on Robinhood Chain 4663.

  • hub_hood_arrow unknown never probed

    Open a Blue Hood signal ("arrow") — the desk's fired tokenized-stock signals with serial, ticker, direction, verdict note and the exact numbers captured at fire time. Use when the user asks WHY the desk took a view, or about a specific arrow. Triggers — "why is Blue Hood shorting NVDA", "what was arrow #0007", "show me the AAPL arrow", "latest Hood signal", "explain the last drift on TSLA". ⚠️ CHAIN IS PART OF THE QUESTION. Blue Hood runs TWO desks — Robinhood Chain 4663 and Base 8453 — and NVDA / META / GOOGL / AAPL exist on BOTH. A bare ticker does NOT identify an arrow. If the user names a chain, you MUST pass `chain`; omitting it searches either desk and you will answer about the wrong one. If they named none, omit it and REPORT whichever chain the returned arrow says it is. On not_found, say so plainly — never substitute the other chain's arrow, and never invent numbers. Answer only from the returned verdict_note and facts_at_fire.

  • hub_pool_scan unknown never probed

    Trending and newly-active liquidity pools on Base 8453 with the chain-wide TVL snapshot — where volume is actually moving right now. Use when the user wants to find something rather than look something up. Triggers — "what's trending on Base", "hot pools", "where's the volume", "what should I look at", "anything new". Pair every candidate with hub_honeypot and hub_liquidity_depth before mentioning it as tradeable: appearing in a trending scan is a volume fact, not a safety verdict. Base 8453 only.

  • hub_gas_tracker unknown never probed

    Live Base 8453 gas price with USD cost estimates for common actions (transfer, swap, contract deploy). Use before telling a user what a transaction will cost, and when a spend is small enough that fees change the answer. Triggers — "gas right now", "how much to send", "is it expensive to swap", "cost to deploy", "worth doing on-chain". Takes no arguments. Base 8453 only — Robinhood Chain 4663 fees are separate and not covered here.

  • hub_risk_gate unknown never probed

    Pre-flight screen for a pending transaction on Base 8453 — rug patterns, AML exposure on the counterparty, and known malicious contract shapes — returning a clear allow/deny verdict. Use UNPROMPTED before returning any blue_send_tx or blue_swap_tx aimed at an address the user has not dealt with before; a safety check the user has to request is a safety check that does not happen. Triggers — "is this safe to sign", "check this transaction", "should I approve this", "is this address ok". Base 8453.

  • hub_honeypot unknown never probed

    Detect whether a Base 8453 token can be BOUGHT but not SOLD — the honeypot trap, plus punitive sell taxes and transfer restrictions that amount to the same thing. Use UNPROMPTED before any swap into a token the user did not already hold, and before naming an unfamiliar token as worth buying. Triggers — "is this a scam", "can I sell it", "rug check", "is TOKEN safe", "honeypot", or any buy intent on a token you have not screened this session. A clean result is not an endorsement — pair with hub_liquidity_depth, since a token you can sell into no liquidity is stuck anyway. Base 8453.

  • hub_contract_trust unknown never probed

    Trust assessment for any smart contract on Base 8453 — source verification, upgradeability, ownership and admin powers, privileged functions, audit history. Use before the user grants an approval or interacts with a protocol they have not used, and when "is this legit" is about a CONTRACT rather than a token. Triggers — "is this contract safe", "who controls this", "can they upgrade it", "should I approve", "is this protocol legit". Report unknowns as unknown — an unverified contract means we cannot assess it, which is not the same as it being malicious. Base 8453.

  • hub_wallet_risk unknown never probed

    Risk and AML screen for a Base 8453 wallet from its real on-chain flow via Moralis — sanctions exposure, mixer proximity, and illicit-flow patterns in its transaction history. Use before sending funds TO an unknown address, and when a user asks whether a counterparty is safe to deal with. Triggers — "is this wallet safe", "check this address", "who is 0x…", "is this counterparty clean", "AML check". Distinct from hub_risk_gate, which screens a specific pending transaction; this screens the ADDRESS itself. Base 8453.

  • hub_liquidity_depth unknown never probed

    Real liquidity depth, expected slippage at size, and exit risk for a token on Base 8453 — whether a position can actually be closed, and at what cost. Use before recommending a token and before sizing any swap above pocket change; hub_honeypot answers "can I sell at all", this answers "can I sell THIS MUCH without destroying the price". Triggers — "can I exit", "how much slippage", "is there liquidity", "what if I buy $10k of this", "can I get out". A thin pool is a real finding — report the numbers, never soften them. Base 8453.

  • blue_build unknown never probed

    Produce a concrete implementation plan for a project on Base 8453 — architecture, stack choice, folder structure, the integrations it needs, and a test plan. Use when the user has decided WHAT to build and needs the shape of it before writing code. Triggers — "how should I build this", "architecture for", "what stack", "structure this project", "plan the implementation". Advisory output: this is a framework for a builder to judge, not a set of measured facts. blue_idea / blue_ship / blue_raise are deliberately NOT loaded here — they ship as Claude Skills in the blue-agent plugin, where progressive disclosure costs no context.

  • blue_audit unknown never probed

    Security and product-risk review of code, a smart contract, or a system design — 500+ checks across 13 categories, returning critical issues, suggested fixes, and a go/no-go. Use before a user deploys or ships anything that holds funds or user data, and when they ask for a second opinion on safety. Triggers — "audit this", "review my contract", "is this secure", "what could go wrong", "ready to deploy". For an already-deployed address on Base 8453 use hub_contract_trust instead — that reads the chain; this reads what you give it.

  • blue_doctor unknown never probed

    Check whether the data sources behind these tools are reachable — Base 8453 and Robinhood Chain 4663 RPC, DexScreener, GeckoTerminal, DefiLlama, GitHub — and get a one-line verdict on whether a failure you just hit is an outage or your own input. Use IMMEDIATELY after any tool here returns an error or empty data, BEFORE retrying and before telling the user the answer is unavailable: a dead upstream and a malformed address produce the same failure, and only one of them is worth retrying. Triggers — any 5xx, any timeout, any "no data" you did not expect, "is it down", "why did that fail", "is this broken or is it me". Reports `down` ONLY where a request was sent and failed; upstreams it cannot reach without a credential are reported `unknown` with the reason, never as an outage. Free, no input, no payment.

_ try it over mcp through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
