Skysay plugin for Cursor and Grok Bot
Give your agent a real phone number. With Skysay, an agent can check coverage, get a number, place AI voice calls, send SMS and read call results through Skysay's hosted MCP server. 100+ countries covered; channels vary by country and number type.

Connect
- Install Skysay from the marketplace (Cursor: Customize → Plugins; Grok Bot: Connect apps).
- When asked, authenticate. Skysay opens its own sign-in page (verified email code, or Google/GitHub). Review the client, workspace and permissions on the consent screen, then choose Allow access.
- Ask the agent: "Use Skysay account_overview and summarise my workspace. Do not place calls or send SMS."
| Setting | Value |
|---|---|
| Server URL | https://api.skysay.ai/mcp |
| Transport | Streamable HTTP |
| Authentication | OAuth 2.0 authorization code with PKCE S256; dynamic client registration and Client ID Metadata Documents supported; no client secret |
| Read-only alternative | https://api.skysay.ai/mcp/read-only (five read tools, no calls or writes) |
The default grant is read-only: workspace, agents, call metadata, coverage, numbers, onboarding and policy evaluation. Calling (calls:write), SMS (sms:send, sms:read), transcripts (recordings:read), number requests (numbers:write) and top-ups (wallet:write) need extra consent. Revoke access any time under Connected apps on the API keys page in your Skysay workspace.
Costs
Connecting is free. Phone numbers, phone calls and SMS use purchased Skysay funds; the one-time $5 welcome credit only covers browser testing inside Skysay. See https://skysay.ai/pricing. The skill shows the expected cost and waits for your approval before any call, text, number request or top-up. That approval step is the assistant's behaviour, not something OAuth enforces, so review consent scopes carefully.
Example prompts
- "Which Skysay number types are available in Germany, and what do they cost?"
- "Check my UK number's outbound readiness, prepare one short test call to the number I give you, and show me the cost before dialling."
- "Check whether my number can send SMS and draft this text for my approval: …"
- "Show the status and transcript of my last Skysay call."
