Wixzel Voice MCP

The Wixzel Voice MCP server enables AI agents to build voice assistants and place real phone calls over a user's own SIP trunk. It provides tools for managing phone numbers, initiating calls, and reviewing usage logs, integrating directly with MCP clients like Claude and Cursor.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http wixzel-mcp https://mcp.voice.wixzel.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add wixzel-mcp --url https://mcp.voice.wixzel.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable wixzel-mcp in your MCP settings.
Cursor configuration
