 ## Quick Start
 
+Each snippet sends your own Pyth Pro API key as an `Authorization: Bearer` header, so you set it once (see [Access Token](#access-token)).
+
+### Claude Code
+
+```sh
+claude mcp add --transport http pyth https://mcp.pyth.network/mcp --header "Authorization: Bearer YOUR_TOKEN"
+```
+
 ### Claude Desktop
 
-Add to your `claude_desktop_config.json`:
+Claude Desktop reaches remote servers only through custom connectors, which cannot send a header. To set the key once, bridge with [`mcp-remote`](https://www.npmjs.com/package/mcp-remote) (needs Node.js) in `claude_desktop_config.json`:
 
 ```json
 {
   "mcpServers": {
     "pyth": {
-      "url": "https://mcp.pyth.network/mcp"
+      "command": "npx",
+      "args": ["-y", "mcp-remote@0.14.3", "https://mcp.pyth.network/mcp", "--header", "Authorization:${PYTH_AUTH_HEADER}"],
+      "env": { "PYTH_AUTH_HEADER": "Bearer YOUR_TOKEN" }
     }
   }
 }
 ```
 
-### Claude Code
+`mcp-remote` is a community package, not maintained by Pyth, and it handles your key; the snippet pins the version we tested.
 
-```sh
-claude mcp add pyth --transport http https://mcp.pyth.network/mcp
-```
+Or add `https://mcp.pyth.network/mcp` under **Settings → Connectors → Add custom connector**, and pass the key per call.
 
 ### Cursor
 
-Add to `.cursor/mcp.json` in your project:
+Add to `~/.cursor/mcp.json` (global, so the key stays out of your repo):
 
 ```json
 {
   "mcpServers": {
     "pyth": {
-      "url": "https://mcp.pyth.network/mcp"
+      "url": "https://mcp.pyth.network/mcp",
+      "headers": { "Authorization": "Bearer YOUR_TOKEN" }
     }
   }
 }
 ```
 
-### Windsurf / Other Clients
+### VS Code
 
-Any MCP client that supports StreamableHTTP can connect using the URL:
+Add to `.vscode/mcp.json`. VS Code prompts for the key once and stores it securely:
 
+```json
+{
+  "inputs": [
+    { "type": "promptString", "id": "pyth-token", "description": "Pyth Pro API key", "password": true }
+  ],

+Any MCP client that supports Streamable HTTP: connect to `https://mcp.pyth.network/mcp` with the header `Authorization: Bearer YOUR_TOKEN`.

 Every user brings their own Pyth Pro access token. It is required for `get_latest_price`, `get_historical_price`, `get_price_range` and `get_candlestick_data`. `get_symbols` works without one, but with a token it also lists feeds visible only to Pro keys and marks each feed `entitled: true/false` (whether your token can query it right now). `convert_date_to_timestamp` never needs one.

   - **Per call**: the `access_token` tool parameter. Your assistant asks for it when no token is configured. Clients that cannot send headers (e.g. Claude Desktop custom connectors) use this.
 - The server never has a key of its own: the hosted server ignores `PYTH_PRO_ACCESS_TOKEN` in its own environment and only uses the key each user sends.
