Bamsai MCP

Provides Korean blue-chip prices 24/7 from Hyperliquid perps in KRW, including pre-open price and arbitrage opportunities. It helps LLM-based auto-trading bots and investors determine if domestic market opening prices will follow overnight global price movements by showing price differences and historical accuracy rates.

get_arbitrage

Advertised by the server during the last successful anonymous check.

Premium between Hyperliquid perp (mid) and KRX price, its usual level (5-day regular-session median) and the net left after costs on the gap beyond that level. net.netPct subtracts fees, tax, FX, funding, order-book slippage for notionalKrw (net.costs.slippage, net.fills: volume-weighted fill prices per leg) and the price move during the gap between the two orders (net.costs.latency = 1-minute volatility × √(lagSec/60)). net.depthLimited / net.maxNotionalKrw: the visible book can fill less than notionalKrw. All assets if asset is omitted

predict_open

Advertised by the server during the last successful anonymous check.

Where the next domestic re-open (08:00–08:10 average on KRX/NXT, vs the 20:00 close) stands, for SMSN/SKHX/HYUNDAI. While the domestic market trades, status=in-session and preOpen is Hyperliquid at today's 08:00 open. Otherwise: the Hyperliquid price in KRW now and at the US close, how often past re-opens followed Hyperliquid at this stage of the night (night.follow.ratePct), the 80% band, and the overall follow rate (backtest.followRatePct). probUp and the expected price are model output, not a promise

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http bamsai-mcp https://bamsai.kr/api/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add bamsai-mcp --url https://bamsai.kr/api/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable bamsai-mcp in your MCP settings.

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Gemini CLI configuration

gemini mcp add --transport http bamsai-mcp https://bamsai.kr/api/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
