Frequently asked questions

What is the Ably MCP server?

The Ably MCP server is an Communication Model Context Protocol server that lets Claude Code, Cursor, Windsurf, VS Code with Copilot, and other MCP-compatible AI agents publish and subscribe to Ably realtime channels for pub/sub messaging from AI agents. It exposes Ably's capabilities as tools the AI can call directly from your editor or CLI.

How do I install Ably MCP with Claude Code?

The fastest way is the MCPizy CLI: run `mcpizy install ably` and MCPizy will add the server to your `.claude.json` automatically. You can also install it manually by adding an entry under `mcpServers` in `.claude.json` with the command `npx -y @ably/mcp-server` and restarting Claude Code.

Is Ably MCP free?

Yes. The Ably MCP server is free and open source (see the GitHub repository linked on this page). You may still need a Ably account or API key to connect the server to the underlying service, but the MCP layer itself has no MCPizy subscription cost.

Does Ably MCP work with Cursor and Windsurf?

Yes. Any MCP-compatible client works — including Claude Code, Claude Desktop, Cursor (via `.cursor/mcp.json`), Windsurf, VS Code with Copilot Chat, and custom agents built on the MCP SDK. The same install command targets all of them; only the config file path differs.
