# web_read

Reads the current page of a web session so you can reason over it. mode='text' (visible text, default), 'a11y' (compact accessible tree of links/buttons/fields — best for deciding what to click), or 'html' (raw DOM). Returns an explicit no_session error if the session isn't open — never a silent empty.

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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "web_read",
    "arguments": {}
  }
}
```

## Why web_read is rated Low

This tool retrieves and queries web page content in various formats for reasoning purposes. It has no side effects, does not create, modify, delete, or execute operations. It is purely observational, making it a Read category tool with low severity since misuse would only expose information the user can already access on their own screen.

From the tool's own definition: "Tool description explicitly states it 'Reads the current page' and 'Returns an explicit no_session error if the session isn't open — never a silent empty.' The three modes (text, a11y, html) all retrieve and return data without modifying state."

## Use case

AI agents call web_read to retrieve information from Local without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "web_read": {}
  }
}
```
