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

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

```

## Why open-browser is rated High

Opening a browser profile triggers an external operation (launching a browser process with a specific fingerprint profile), which falls under Execute. The description is empty, lowering confidence, but context from server description and sibling tools strongly suggests browser execution.

From the tool's own definition: "Tool name 'open-browser' on a server described as enabling 'opening... browser profiles'; sibling tools include 'close-browser', 'connect-browser-with-ws', suggesting this launches/opens a browser instance."

## Use case

AI agents invoke open-browser to trigger actions in AdsPower LocalAPI MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
