Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to youraitools.co, which also runs its endpoint. That identifies the publisher; it does not make the server's tools safe.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

A remote MCP server that pre-checks a Hyperliquid perpetual order before an agent sends it, reporting rejection risk, cost, liquidation and funding.

What you can do: Check a proposed Hyperliquid perp order before submission, giving coin, side and size in coins or notional in USD, with optional limit price, leverage, cross or isolated margin and reduceOnly. Get a verdict on whether the exchange would reject the order and suggested corrected values. See estimated cost, liquidation and market impact, plus funding information for the order.
When to use it: Use it when an agent is about to place or size a Hyperliquid perpetual futures order and you want a dry-run sanity check on validity, cost and liquidation risk before anything is sent to the exchange.
Requirements: A remote streamable HTTP endpoint; no package, environment variables or headers are declared. The assistant connects to the hosted service, so network access is required. No authentication is declared.

Before you install

The check is advisory and does not place the order itself; actual execution and any resulting spending happen elsewhere. Results such as rejection verdicts, costs and liquidation estimates come from a third-party service and should not be treated as guaranteed. Order details you submit are sent to that external endpoint.

Installation

In SourceWeft

Open PerpCheck in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/co.youraitools%2Fperpcheck/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Hyperliquid pre-trade order check

Checks a Hyperliquid perp order BEFORE your agent sends it: would the exchange reject it, and what does it cost and risk? Give coin, side and size (coins, as you would send it) or notional (USD); optional limit price (omit = market order), leverage, margin cross/isolated, reduceOnly. Returns verdict REJECT_LIKELY / CAUTION / OK, issues[] with fix values (size decimals, price tick, $10 minimum, max leverage by margin tier, isolated-only, OI cap, delisted, far-from-mark), warnings[], rules, isolated liquidation estimate and distance, taker impact from the live L2 book, funding carry per day, market facts, confidence and sources_failed. Read-only: never places, signs or holds orders and needs no keys. Free: 30 calls/day per IP with full results (max 10/min; invalid input is not counted). After that the tool returns an error with the x402 pay URL ($0.01 USDC per full check at /v1/full, or $0.003 lite at /v1/lite) or prepaid credits. Not financial advice; the exchange decides whether an order is accepted. PerpCheck is a read-only pre-trade check: it never places, signs or holds orders, has no custody and never asks for keys.
