# session_list

A read tool on the Looking Glass MCP server.

Agent View of the PolicyLayer registry record for `session_list`. HTML page: https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/session-list

## Facts

- Tool: `session_list`
- Server: Looking Glass (`looking-glass-mcp`) — https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp.md
- Install: `npx -y looking-glass-mcp`
- Homepage: https://github.com/Sahib-Sawhney-WH/LookingGlass
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Allowed

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

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

## Why session_list is rated Low

The naming convention (list suffix) strongly suggests retrieval of session data without side effects. Empty description reduces confidence slightly, but the tool appears to retrieve or enumerate existing browser sessions rather than modify, delete, or execute operations. Consistent with other Read tools like 'browser_action_history' and 'browser_console_messages' on the same server.

From the tool's own definition: "Tool name 'session_list' indicates a listing/querying operation consistent with Read category. No description provided to clarify destructive, write, or execute capabilities."

## Use case

AI agents call session_list to retrieve information from Looking Glass 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 Looking Glass:

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