English

MCP (Model Context Protocol) server and OpenClaw Skill for integrating with Grizzly SMS — a platform for SMS verification codes and virtual phone numbers. Compatible with Cursor, Claude Desktop, OpenClaw (MCP and Skill modes).

What This Project Provides

Mode Description Use Case
MCP Server Standards-based MCP server exposing Grizzly API tools Cursor, Claude Desktop, OpenClaw with mcpServers
OpenClaw Skill Instruction-based skill using exec + CLI script OpenClaw skills-only setup (no mcpServers)

Features

MCP Server

  • Phone operations: request_number, get_status, set_status
  • Account: get_balance
  • Info: get_countries, get_services, get_prices

OpenClaw Skill

  • Dialog-based API key: Bot asks for the key during the conversation
  • Balance & top-up: Check balance and provide crypto wallet (USDT TRC-20) for top-up
  • Number lifecycle: Request number, poll for SMS, complete or cancel activation
  • Full registration workflow: Resolve service/country codes → rent number → open browser → fill forms → enter SMS code
  • Formatted output: Phone, activation ID, and SMS in copy-friendly format (monospace on Telegram)

OpenClaw Skill Pipeline

  1. API key — Bot asks: Please provide your Grizzly SMS API key
  2. Balance & top-up — Bot can show balance and crypto wallet address for USDT TRC-20 top-up
  3. Number — Bot rents a number for the requested service and country
  4. Status — Bot can cancel an activation or request a new SMS
  5. SMS — Bot polls and returns the verification code
  6. Complete — Bot marks activation complete after code is used

See CONFIG.md for OpenClaw skill setup.

      "mcpServers": {
        "grizzly-sms": {
          "command": "node",
          "args": ["/absolute/path/to/grizzly-sms-mcp/dist/index.js"],
          "env": {
            "GRIZZLY_SMS_API_KEY": "your_api_key",
            "GRIZZLY_SMS_BASE_URL": "https://api.grizzlysms.com"
          }
        }
      }
    }
  }
}

Use absolute paths. Restart after changes: openclaw gateway restart


Configuration: OpenClaw Skill (skills-only, no mcpServers)

  1. Add skill path to openclaw.json:
{
  "skills": {
    "load": {
      "extraDirs": ["/absolute/path/to/grizzly-sms-mcp"]
    },
    "entries": {
      "grizzly_sms": {
        "enabled": true
      }
    }
  }
}
  1. Enable exec and optionally browser tools for the agent
  2. Restart: npx openclaw gateway restart

Full setup (exec approvals, browser tool, API key in dialog) — see CONFIG.md.

MCP (Model Context Protocol) сервер и OpenClaw Skill для интеграции с Grizzly SMS — платформой SMS верификации и виртуальных номеров. Совместимо с Cursor, Claude Desktop, OpenClaw (режимы MCP и Skill).

Что предоставляет проект

Режим Описание Когда использовать
MCP Server MCP‑сервер с инструментами Grizzly API Cursor, Claude Desktop, OpenClaw с mcpServers
OpenClaw Skill Skill на exec + CLI‑скрипт OpenClaw только со skills (без mcpServers)

Возможности

MCP Server

  • Номера: request_number, get_status, set_status
  • Аккаунт: get_balance
  • Справочники: get_countries, get_services, get_prices

OpenClaw Skill

  • API‑ключ в диалоге: бот запрашивает ключ в чате
  • Баланс и пополнение: показывает баланс и криптокошелёк (USDT TRC-20) для пополнения
  • Жизненный цикл номера: аренда номера, ожидание SMS, завершение или отмена активации
  • Полный workflow регистрации: определение сервиса/страны → аренда номера → браузер → заполнение форм → ввод SMS‑кода
  • Форматированный вывод: номер, ID активации и SMS в удобном для копирования виде (моноширинный текст в Telegram)

Пайплайн OpenClaw Skill

  1. API‑ключ — бот спрашивает: Выдайте API ключ Grizzly SMS
  2. Баланс и пополнение — бот показывает баланс и адрес кошелька USDT TRC-20
  3. Номер — бот арендует номер для указанного сервиса и страны
  4. Статус — бот может отменить активацию или запросить новый SMS
  5. SMS — бот опрашивает статус и возвращает код
  6. Завершение — бот помечает активацию выполненной после использования кода

Подробная настройка — в CONFIG.md.

Требования

      "args": ["/абсолютный/путь/к/grizzly-sms-mcp/dist/index.js"],
      "env": {
        "GRIZZLY_SMS_API_KEY": "ваш_api_ключ",
        "GRIZZLY_SMS_BASE_URL": "https://api.grizzlysms.com"
      }
    }
  }
}

OpenClaw (mcpServers)

Путь: ~/.openclaw/openclaw.json (macOS/Linux) | %APPDATA%\.openclaw\openclaw.json (Windows)

{
  "agents": {
    "list": [{
      "id": "main",
      "mcpServers": {
        "grizzly-sms": {
          "command": "node",
          "args": ["/абсолютный/путь/к/grizzly-sms-mcp/dist/index.js"],

          }
        }
      }
    }
  }
}

Используйте абсолютные пути. После изменений: openclaw gateway restart


Конфигурация: OpenClaw Skill (только skills, без mcpServers)

  1. Добавьте путь к skill в openclaw.json:

  "skills": {
    "load": {
      "extraDirs": ["/абсолютный/путь/к/grizzly-sms-mcp"]
    },
    "entries": {
      "grizzly_sms": {
        "enabled": true
      }
    }
  }
}
  1. Включите инструменты exec и по необходимости browser
