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
- API key — Bot asks: Please provide your Grizzly SMS API key
- Balance & top-up — Bot can show balance and crypto wallet address for USDT TRC-20 top-up
- Number — Bot rents a number for the requested service and country
- Status — Bot can cancel an activation or request a new SMS
- SMS — Bot polls and returns the verification code
- Complete — Bot marks activation complete after code is used
See CONFIG.md for OpenClaw skill setup.
Prerequisites
- Node.js 18+
- Grizzly SMS API key — register at grizzlysms.com, then get it from the API section
