Overview

Description from the maker (original English)

Self-custodial Hyperliquid perps, Polymarket, staking and yield for AI agents, with a kill switch.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Crypto & blockchain
  • You need to fill in: Authorization

Install

Pick the AI app you use, then copy the settings.

Before you install

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http terminal https://terminal.vectorialdata.com/api/mcp --header 'Authorization: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "terminal": {
      "url": "https://terminal.vectorialdata.com/api/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

    "terminal": {
      "type": "http",
      "url": "https://terminal.vectorialdata.com/api/mcp",

        "Authorization": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • Authorization secret HTTP header
    Bearer . Docs, markets and registration work without it; the register_agent tool returns the key.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.

  • get_docs

    The complete Agent API manual (markdown): auth, trading, limits, withdrawals, error catalog.

  • list_markets

    Tradeable markets with live prices and the precision metadata needed to size orders (size_decimals, min_size, price rules, $10 min notional).

  • get_registration_challenge

    Step 1 of creating an agent account: get a nonce+message to sign (EIP-191) with the agent's own EVM wallet.

  • register_agent

    Step 2: register with the signed challenge. Returns the api_key ONCE — store it and configure it as the Authorization header of this MCP server. New accounts start in paper mode.

  • get_account

    Your agent account: status, mode (paper|live), scopes, live balances, deposit address, limits.

  • get_positions

    Open positions (live: venue truth; paper: from your fills).

  • list_orders

    Your authoritative order ledger (cursor-paginated). Paper triggers appear as trigger_tp/trigger_sl rows.

  • get_metrics

    Your tear-sheet: win rate, net PnL, fees, drawdown, Sharpe, equity curve — computed server-side from the authoritative ledger.

  • place_order

    Place an order. PAPER mode executes immediately (simulated fill against real prices — nothing to sign). LIVE mode trades from your trading wallet (create_trading_wallet + authorize_trading_key first) and returns typed_data to sign with your TRADING key, then submit_order. Fees: 0

  • submit_order

    Execute a prepared LIVE order with your trading key's signatures (one per typed_data, in order).

  • close_position

    Close an open position (fully or size_pct). Paper executes immediately; live returns typed_data for signing.

  • protect_position

    Attach post-hoc reduce-only TP/SL triggers to an open position. Paper executes immediately.

  • cancel_order

    Cancel a resting order by ledger id. Paper executes immediately.

  • submit_intent

    Execute a prepared intent (cancel/protect/withdraw) with the wallet's signatures.

  • log_decision

    Log WHY you traded (your audit trail and future public track record). Pass order_id to correlate.

  • get_limits

    Your bounded-autonomy rails (caps, allowlists, pending loosenings).

  • update_limits

    Adjust rails. Tightening is instant; loosening waits 24h (see /limits/escalate in the docs for the wallet-signed immediate path).

  • set_mode

    Flip paper ↔ live. Fund the wallet before going live (see get_account.deposit).

  • kill_switch

    Instant pause: every subsequent prepare/submit is rejected until resume_trading (which needs the wallet's signature).

  • resume_trading

    Reactivate after kill_switch. Needs the account WALLET's signature (the api key alone cannot undo a pause): call it with no arguments to get { nonce, message }, sign `message` with your agent wallet (EIP-191), then call it again with nonce + signature.

  • get_withdrawals_config

    Money-out policy: mode (disabled|autonomous|human_passkey), strict destinations, guardian link.

  • list_pending_withdrawals

    Your withdraw intents and their approval lifecycle (human_passkey). Approved intents include signable actions.

  • prepare_withdrawal

    Prepare a withdrawal (USDC → Arbitrum). Requires withdraw scope + matured allowlist; returns typed_data to sign externally (or approval_state=pending under human_passkey). MCP alone can NEVER move funds — execution requires the wallet's signature via submit_intent.

  • guardian_status

    Human guardian link state (human_passkey mode).

  • invite_guardian

    Mint a single-use invite (48h) for a human to become this agent's withdrawal guardian. Hand them the accept_url.

  • list_webhooks

    Your webhook endpoints (max 5): url, subscribed event types, status, failure counters. Also returns the full event-type catalog.

  • create_webhook

    Register a webhook endpoint (public https). Returns the HMAC signing secret ONCE (vd_whsec_…) — deliveries are signed `x-vd-signature: t=…,v1=hex(hmac_sha256(secret, t + '.' + body))`, at-least-once, dedupe by event id. Omit event_types to receive everything.

  • get_webhook

    One webhook + its last 20 delivery attempts (status codes, retries, dead letters) — the delivery debugging surface.

  • delete_webhook

    Remove a webhook endpoint (its queued deliveries are dropped).

  • test_webhook

    Send a synchronous signed test event to a webhook and report the receiver's response — verify your endpoint + HMAC handling before relying on real events.

  • list_copy_leaders

    Strategies available to copy, with the SAME numbers a human sees, as a DAILY snapshot (UTC: the same object all day): time-weighted return net of fees (immune to the leader's deposits and withdrawals — never a return on capital), max drawdown, Sharpe, trade count and the leader's

  • get_copy_status

    What this agent is copying, per leader. Live follows: your copy wallet is a Hyperliquid account you own — read its positions and every fee transfer directly from Hyperliquid (info: clearinghouseState and userNonFundingLedgerUpdates) with the address from GET /copy/wallet. get_pos

  • follow_leader

    Start copying a leader with real funds: mode 'live' mirrors from your copy wallet — create and fund it first with create_copy_wallet. Mirrors begin at the leader's NEXT fill; past trades are never backfilled. Every mirror is sized on the copy wallet's FULL value (what you funded

  • unfollow_leader

    Stop copying a leader. Live: 'stopping' while the engine closes your mirrored positions and settles fees. Requires the 'copy' scope.

  • create_copy_wallet

    Create the copy wallet needed for LIVE copying. You generate a P-256 keypair and send only the PUBLIC key — you own the wallet and can withdraw with your owner key at any time, without us. Our signer is locked by policy to fee destinations, which is what makes all fees settle aut

  • get_trading_wallet

    Your trading wallet — the Hyperliquid account LIVE orders trade from: address and balances, trading key status (and when to renew it), how to fund it, fees (0.25% per perps trade, the same everyone pays, collected automatically) and custody terms.

  • create_trading_wallet

    Create your trading wallet (required for LIVE trading; your agent wallet must have nothing open). You generate a P-256 keypair and send only the PUBLIC key: it becomes the wallet's OWNER and never leaves your process. Our signer on it can only pay trading fees to our treasury and

  • authorize_trading_key

    Authorize the key that signs your LIVE orders. Generate a NEW secp256k1 key (no Hyperliquid history — Hyperliquid refuses keys that already have an account). Call with no arguments to get the message that key must sign (EIP-191) as proof. Fund the trading wallet first. Then call

  • send_trading_funds_home

    Move USDC from your trading wallet back to your agent wallet, inside Hyperliquid (the destination is always your own agent wallet). Pending trading fees are collected first. TWO CALLS: the first returns one payload_b64 per rail with its `verify` list (destination = your agent wal

  • get_copy_wallet

    Your copy wallet: address to fund, whether it is ready for live copying, and the custody terms.

  • get_scope_challenge

    Step 1 of gaining a new scope ('copy' to follow leaders, 'withdraw' to move funds). Returns a message to sign with your agent wallet. keys/rotate can only NARROW scopes — new authority always costs a wallet signature, and the challenge is bound to the intent so a signature given

  • escalate_scope

    Step 2: submit the signature from get_scope_challenge and receive a NEW api key carrying the scope. Store it and replace the Authorization header of this MCP server — the old key keeps working during a short grace window.

  • rotate_key

    Mint a fresh api key, optionally NARROWING its scopes. Cannot add authority — use get_scope_challenge + escalate_scope for that. Previous keys stay valid for a short grace window so a running bot does not lose access mid-flight.

  • list_prediction_markets

    Prediction markets you can trade now (Polymarket): events with their markets and, per outcome, the CLOB token_id you trade and its price (a probability 0–1 = USD per share; a winning share pays $1). Default: by 24h volume. Optional: query (search), event_slug (one event), tag (a

  • get_prediction_book

    Live order book of one prediction outcome (best first): best bid/ask, mid, tick size and the top levels with sizes in shares.

  • get_predictions_account

    Your predictions account: your deposit wallet (a Polymarket smart wallet only your agent wallet controls), activation steps, cash (pUSD = USD), WHERE TO DEPOSIT (any supported chain; lands as pUSD in minutes), anything pending and the last relayer transaction.

  • activate_predictions

    Enable prediction markets (once, gasless). Predictions trade LIVE only (no paper simulation) and need 'polymarket' in venue_allowlist. TWO CALLS: the first (no arguments) deploys your deposit wallet and returns actions[] — sign each typed_data (EIP-712) with your AGENT wallet, in

  • place_prediction_order

    Buy or sell a prediction outcome with a fill-or-kill market order (fills entirely at a protected price or nothing happens). BUY: amount_usd (min $1; Polymarket's taker fee and our builder fee go on top — the same everyone pays; max_spend_usd caps the all-in spend). SELL: shares.

  • submit_prediction_order

    Execute a prepared prediction order with your agent wallet's signature over its typed_data. Returns the fill (shares, average price, USD) or why it didn't fill (nothing is charged on a miss).

  • get_prediction_positions

    Your open prediction positions (Polymarket's numbers): shares, average and current price, cost, value, P&L, and whether a resolved winner is waiting to be collected (collectable).

  • send_predictions_home

    Move predictions cash back to YOUR agent wallet as native USDC (polygon, arbitrum or base; min $2) through Polymarket's bridge — the destination is always your own agent wallet. Returns a batch typed_data: sign it with your AGENT wallet, then submit_predictions_batch. Works while

  • collect_prediction_winnings

    Collect resolved WINNING positions into your predictions cash (Polymarket usually does this automatically at resolution; use this if get_prediction_positions shows collectable: true). Optional condition_id. Returns a batch typed_data: sign it with your AGENT wallet, then submit_p

  • submit_predictions_batch

    Execute a prepared send_predictions_home or collect_prediction_winnings batch with your agent wallet's signature (gasless, via Polymarket's relayer).

  • get_earn

    Earn for agents: HLP (Hyperliquid's market-making vault), HYPE staking and USDC lending — rates, fees, lockups and validators; whether you can enter (live, 'earn' in venue_allowlist, certification); your trading wallet's balances and Earn positions. Everything runs from your trad

  • certify_earn

    One-time Earn eligibility certification (valid 1 year): the agent's OPERATOR certifies it is not in an excluded jurisdiction (read get_earn → certification_text first). If the request comes from an excluded country (agents often run in US data centers), call again with confirm_op

  • earn_hlp_deposit

    Deposit USDC from your trading wallet into HLP. Entry fee 0.55% (collected after the deposit lands), min $5.03, 4-day lockup; counts toward your exposure cap. Returns operation_id + signatures_needed[]: sign EACH step with the signer it names — 'owner' = your OWNER P-256 key over

  • earn_hlp_withdraw

    Withdraw from HLP back to your trading wallet (free; after the 4-day lockup). Works while paused. Returns operation_id + signatures_needed[]: sign EACH step with the signer it names — 'owner' = your OWNER P-256 key over payload_b64 (decode it and check every `verify` line against

  • buy_hype

    Buy HYPE with USDC in your trading wallet (spot, immediate-or-cancel at up to +1% from mid; fee 0.25% in USDC; Hyperliquid's minimum order is $10). The outcome says how much HYPE arrived — stake it with stake_hype. Returns operation_id + signatures_needed[]: sign EACH step with t

  • sell_hype

    Sell spot HYPE for USDC in your trading wallet (immediate-or-cancel at no less than -1% from mid; the same spot sell fee everyone pays). Works while paused. Returns operation_id + signatures_needed[]: sign EACH step with the signer it names — 'owner' = your OWNER P-256 key over p

  • stake_hype

    Stake spot HYPE with a validator (get_earn → products.staking.validators, neutral order). Entry fee 0.25% in HYPE; rewards are paid daily on the delegation. Two owner steps: into the staking balance, then delegate. Returns operation_id + signatures_needed[]: sign EACH step with t

Common questions

Is Vectorial Data Terminal: Hyperliquid, Polymarket & yield for AI agents safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.3.1) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Highwire, DeFi Quant Yield & Risk Engine, gasrescue

Vectorial Data Terminal — MCP server for AI agents

Let Claude, ChatGPT, Cursor or your own bot trade Hyperliquid perps and Polymarket prediction markets, and earn yield (HYPE staking, HLP, USDC lending), from wallets your agent owns, inside limits our server enforces, with a kill switch.

  • Hosted MCP server: https://terminal.vectorialdata.com/api/mcp (Streamable HTTP)
  • REST API: https://terminal.vectorialdata.com/api/agent/v1 · OpenAPI
  • Full manual (for machines and people): /api/agent/v1/docs
  • Overview: terminal.vectorialdata.com/agents
  • Official MCP Registry: com.vectorialdata/terminal

This repository holds documentation and signing examples. The server itself is hosted by Vectorial Data; you don't run anything to use it.

68 tools, each with described arguments and MCP annotations (read-only / destructive / idempotent).

The safety model

  • Self-custodial. Your agent owns its keys: an EVM wallet (its identity), and for live trading a trading wallet whose OWNER is a P-256 key your bot holds, plus a trading key that owner authorizes on Hyperliquid. Every live order and every money movement is signed by your keys. The MCP server never sees a private key and cannot move funds by itself: live tools return what to sign, and you sign outside the MCP boundary.
  • Limits enforced by the server, not the model. Per-order and account-wide exposure caps (perps + predictions + Earn), a daily-loss breaker, asset and venue allowlists. Tightening is instant; loosening waits 24 hours unless your wallet signs it.
  • Kill switch. kill_switch pauses everything new at once; exits and moving money home keep working.
  • Fees are the same a person pays on the Terminal: 0.25% per perps trade (settled automatically), Polymarket's builder fee inside the fill, 0.55% to enter HLP, 0.25% to stake HYPE, 20% of the yield on USDC lending. Leaving Earn is free. Paper mode is free.

Signing, in one picture

Live tools answer with steps to sign. Each step names its signer:

  • "signer": "owner" → decode payload_b64 (base64 of the exact JSON request to the wallet provider), check every line in verify against your own records, then sign the bytes with your OWNER P-256 key (ECDSA over SHA-256, DER, base64).
  • "signer": "trading_key" → sign typed_data (EIP-712) with your trading key.

Then submit the signatures in order. See examples/02-sign-operation.ts for a complete signer that refuses anything it did not expect.

Never sign a payload you have not decoded and checked. A signer that signs blind is the one way a compromised server, network or prompt could make your agent pay someone else.

Examples

  • 01-register-and-paper-trade.ts — create a wallet, register, place a paper order, read positions and metrics.
  • 02-sign-operation.ts — sign and submit any live Earn / move operation (owner and trading-key steps), checking each payload before signing.
cd examples

npm install npx tsx 01-register-and-paper-trade.ts

Requires Node 20+.

Jurisdiction

The operator of an agent (the person or entity that controls its keys and funds it) is responsible for being allowed to trade derivatives and prediction markets where they are. Requests from OFAC-sanctioned jurisdictions are refused. Polymarket does not allow trading from some countries, including the United States. Earn asks for a one-time eligibility certification by the operator.
