## Description

Update a watch, including pausing or resuming it. Only the fields you set are changed. [See the documentation](https://rendex.dev/docs/watch#endpoints).

## Props

| Prop | Type | Required | Description |
|---|---|---|---|
| `watchId` | `string` | Yes | The watch to act on. Options are loaded from the connected account. |
| `url` | `string` | No | New page URL to monitor. Changing it re-baselines the watch on the next run. |
| `name` | `string` | No | A human-friendly label for the watch. |
| `intervalMinutes` | `integer` | No | Minutes between automatic checks. Per-plan floors apply (Free 1440, Starter 180, Pro 30, Enterprise 5). |
| `diffMode` | `string` | No | How a change is detected: visual (pixel diff), text (extracted text), or both. |
| `threshold` | `string` | No | Fraction of the page (between 0 and 1) that must change to count as a change. Defaults to 0.01. |
| `webhookUrl` | `string` | No | URL that receives an HMAC-signed POST when a change is detected. Requires a Starter plan or higher. |
| `notifyEmail` | `string` | No | Email to alert on a change. Must match the email on your Rendex account. |
| `paused` | `boolean` | No | When true, the watch is created/left paused and is not scheduled (no credits charged). |
| `renderFullPage` | `boolean` | No | Capture (and diff) the entire scrollable page. Defaults to true for watches. |
| `renderSelector` | `string` | No | Monitor only the element matching this CSS selector instead of the whole page. |
| `ignoreText` | `string[]` | No | Text patterns stripped from both captures before text-diffing so volatile substrings (timestamps, rotating prices, CSRF tokens) don't trigger a change. Wrap a pattern in /…/flags for a regex; anything else is a case-insensitive substring. |
| `minTextChars` | `integer` | No | A text change must add and remove at least this many characters to count — drops micro-edits. |
| `suppressWhilePresent` | `string[]` | No | While the page text contains any of these strings (e.g. Out of stock, Loading), the run is treated as unchanged — no alert, no baseline drift. |
| `uaMode` | `string` | No | Fetch identity for the watch: auto (lead with the RendexWatch UA, retry once with a browser identity if blocked), identify (always the RendexWatch UA), or stealth (always a standard browser identity). |

  projectId: process.env.PIPEDREAM_PROJECT_ID!,
  clientId: process.env.PIPEDREAM_CLIENT_ID!,
  clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
  projectEnvironment: "production",

const accessToken = await pd.rawAccessToken

const transport = new StreamableHTTPClientTransport(

        "x-pd-app-slug": "rendex",
      },
    },
  },
)

const mcp = new Client({ name: "my-agent", version: "1.0.0" })
await mcp.connect(transport)

const { tools } = await mcp.listTools()

// listTools() hands your model this tool's input schema, so it can
// fill the arguments itself:
const result = await mcp.callTool({
  name: "rendex-update-watch",
  arguments: {
    watchId: "Watch",
    url: "URL",
  },
})
```
