# Polyester MCP

Connect Cursor or Claude Desktop to Polyester documentation search and live deposit, withdraw, and market data via the hosted MCP server.

Polyester MCP is a hosted **Model Context Protocol** server. It lets AI assistants (Cursor, Claude Desktop, and other HTTP MCP clients) query Polyester documentation and read live platform configuration — no local setup required.

Connect with a URL only. You do not need to clone a repository or configure environment variables on your machine. The snippet uses the Polyester network this docs site is on.

## Connect in Cursor

Add to **Cursor Settings → MCP** or your workspace `.cursor/mcp.json`:

```json
{
	"mcpServers": {
		"polyester": {
			"url": "https://polyester-mcp-testnet.fabriclabs.workers.dev/mcp"
		}
	}
}
```

Reload MCP in Cursor after saving.

## Other clients

Claude Desktop and other clients that support **remote MCP over HTTP** (Streamable HTTP) can use the same URL. Check your client’s documentation for how to add a remote MCP server URL.
