# happ_login

Авторизация на платформе Happ через браузер. Открывает страницу входа, ждёт подтверждения пользователя и сохраняет токены локально. Вызывай ТОЛЬКО когда пользователь явно попросил залогиниться или подтвердил повторный вход. Никогда не вызывай автоматически в ответ на 401/'Не выполнен вход' — инструмент открывает окно браузера у пользователя.

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

```json
{
  "jsonrpc": "2.0",

## Why happ_login is rated High

This tool triggers external operations: it opens a browser window on the user's machine, waits for user interaction, and then saves authentication tokens locally. This constitutes executing a browser action with significant side effects (credential storage, browser window opening), placing it in the Execute category.

From the tool's own definition: "Открывает страницу входа, ждёт подтверждения пользователя и сохраняет токены локально. Никогда не вызывай автоматически — инструмент открывает окно браузера у пользователя."

## Use case

AI agents invoke happ_login to trigger actions in Platform. 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.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "happ_login": {
      "limits": [
        {
