# Vike Data API — remote MCP server

<img src="assets/logo.png" alt="Vike" width="96" align="right">

Crypto data for AI agents: on-chain wallets and tokens, Hyperliquid, HL Cohorts and Polymarket.

- **Endpoint:** `https://data.vike.io/mcp` (Streamable HTTP)
- **Auth:** OAuth 2.1 sign-in, or a Vike API key in the `X-API-KEY` header ([create a key](https://vike.io/account?tab=api-keys))
- **Docs:** https://vike.io/docs/ai/data/
- **MCP Registry:** `io.vike/data`

The server is hosted by Vike. This repository holds only the connection manifests: a Cursor
plugin, the registry `server.json`, and install notes for agents. There is nothing to build or run.

## What the tools cover

- **On-chain wallets and tokens** on Ethereum, BNB Chain, Base and HyperEVM: wallet flows and
  balances, PnL history, counterparties, first funder, exchange usage, entity labels and risk flags,
  token holders, transfers and a token screener.
- **Hyperliquid perps**: wallet positions and fills, liquidations, leaderboards, builders, market
  stats and candles.
- **HL Cohorts**: hourly long/short positioning of each Hyperliquid perp split by wallet cohort.
- **Polymarket**: markets, order books, trade tape, settlements, wallet profiles, leaderboard and
  smart-money flows.

## Connect

**Claude (claude.ai, Claude Desktop):** Settings → Connectors → Add custom connector → URL
`https://data.vike.io/mcp`, then sign in.

**Claude Code:**

```bash
claude mcp add --transport http vike https://data.vike.io/mcp --header "X-API-KEY: $VIKE_API_KEY"
```

**Cursor:** install the `vike-data` plugin from this repository, or add to `~/.cursor/mcp.json`:

```json
{
  "mcpServers": {
    "vike-data": {
      "url": "https://data.vike.io/mcp",
      "headers": { "X-API-KEY": "YOUR_KEY" }
    }
  }
}
```

Without `headers`, Cursor signs in with OAuth.

**VS Code (GitHub Copilot):** `.vscode/mcp.json`:

```json
{
  "servers": {
    "vike-data": {
      "type": "http",
      "url": "https://data.vike.io/mcp",
      "headers": { "X-API-KEY": "YOUR_KEY" }
    }
  }
}
```

**Cline:** see [llms-install.md](llms-install.md).

**ChatGPT:** add a custom connector with the URL `https://data.vike.io/mcp` and sign in.

Keep keys out of files you commit: use your client's secret store or an environment variable.
