# send_html

Shows HTML content on a display: menus, dashboards, welcome pages, schedules or any custom design. slot 'live' (default) replaces the current content; slot 'idle' stores the default/fallback content shown when nothing live is active (idle requires admin scope). Always pass a short description so later content reads stay meaningful. Exactly one of html or base64_html. For external web pages use send_url; to edit current content call read_display_html first. For polished results load prompt render_premium_display_html or resource agentview://public/design-system. Requires content scope.

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `html` | string | no | Complete HTML document to render. Mutually exclusive with base64_html. |
| `slot` | string | no | Target slot: 'live' (default) replaces current content; 'idle' sets the default shown when idle (admin scope). |
| `token` | string | no | Display-specific demo/preview token for unauthenticated access. NOT the OAuth token. |
| `duration` | integer | no | Seconds the content stays; 0 = indefinite (default). Live slot only. |
| `display_id` | string | yes | 8-character display profile ID, e.g. 'ABCD1234'. |
| `base64_html` | string | no | Base64-encoded HTML (standard base64). Use only when raw HTML cannot survive JSON transport. Mutually exclusive with html. |
| `description` | string | yes | Short human-readable summary of the content, e.g. 'Weekly KPI dashboard'. |
| `access_token` | string | no | Optional bearer token; prefer session_request_id. Distinct from the display-specific 'token'. |
| `session_request_id` | string | no | Session handle from create_auth_session; pass it on every authenticated call. |

Parameters from the server's own tool schema.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "send_html",
    "arguments": {
      "display_id": "<display_id>",
      "description": "<description>"
    }
  }
}
```

## Why send_html is rated Medium

An AI agent can call send_html faster than any human can review: one bad instruction and it creates or modifies resources in agentView by the hundred, each call as confident as the last.

Risk signals: Handles credentials or secrets (token) · Accepts raw HTML/template content (html) · Admin/system-level operation

## Use case

AI agents use send_html to create or update resources in agentView, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your agentView environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches agentView:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "send_html": {
      "limits": [
        {
          "counter": "send_html_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
