概览

What is Callsphere?

Callsphere is a public, read-only Model Context Protocol (MCP) server that gives any AI assistant – including Claude, Cursor, Cline, Continue, Windsurf, Zed, or ChatGPT via JSON-RPC – direct access to CallSphere’s voice‑AI knowledge base, industry ROI calculator, case studies for six verticals, and product facts.

How to use Callsphere?

Connect to https://callsphere.ai/api/mcp using Streamable HTTP transport. Install with claude mcp add --transport http callsphere https://callsphere.ai/api/mcp (Claude Code) or add it to your client’s MCP config (Claude Desktop, Cursor, Cline/Continue/Windsurf). For clients without MCP support, send plain JSON‑RPC 2.0 POST requests to the same endpoint.
