WHAT IT DOES

What send_html does on agentView

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.

Parameter	Type	Required	Description
`html`	string	—	Complete HTML document to render. Mutually exclusive with base64_html.
`slot`	string	—	Target slot: 'live' (default) replaces current content; 'idle' sets the default shown when idle (admin scope).
`token`	string	—	Display-specific demo/preview token for unauthenticated access. NOT the OAuth token.
`duration`	integer	—	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	—	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	—	Optional bearer token; prefer session_request_id. Distinct from the display-specific 'token'.
`session_request_id`	string	—	Session handle from create_auth_session; pass it on every authenticated call.

Parameters from the server's own tool schema.

RISK

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 signalsHandles credentials or secrets (token) · Accepts raw HTML/template content (html) · Admin/system-level operation

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs send_html safely

PolicyLayer is an MCP gateway: it sits between your AI agents and agentView, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For send_html, this is the rule to start with:

send_html Rate-limited

send_html stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

policy.json

{

    "send_html": {
      "limits": [
        {

        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect agentView, apply this rule, and every send_html call is checked against it from then on.

FAQ

Questions about send_html

What does the send_html tool do? +

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. It is categorised as a Write tool in the agentView MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does send_html accept? +

send_html accepts 9 parameters: html, slot, token, duration, display_id, base64_html, description, access_token, session_request_id. Required: display_id, description. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on send_html? +

Register the agentView MCP server in PolicyLayer and add a rule for send_html: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches agentView. Nothing to install.

What risk level is send_html? +

send_html is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit send_html? +

Yes. Add a rate_limit block to the send_html rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block send_html completely? +

Set action: deny in the PolicyLayer policy for send_html. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides send_html? +

send_html is provided by the agentView MCP server (https://agentview.de/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
