Connect your AI app

Claude Desktop connects to remote MCP servers as connectors.

1. Open Settings → Connectors.
2. Click Add custom connector.
3. Give it a name (e.g. VoIP.ms) and paste the server URL:

https://voipms-mcp.ecliptical.io/mcp

1. Save, then click Connect — a browser opens to sign in and choose access.
2. Once connected, the VoIP.ms tools appear in the connector list.

Add the server from the CLI as an HTTP transport:

claude mcp add --transport http voipms https://voipms-mcp.ecliptical.io/mcp

1. Run /mcp inside Claude Code and authenticate when prompted — a browser opens for sign-in and to choose access.
2. After approval the VoIP.ms tools are available in the session.

ChatGPT reaches remote MCP servers through connectors (developer mode / connectors, where available on your plan).

1. In Settings → Connectors, choose to add a custom / remote MCP server.
2. Paste the server URL:

https://voipms-mcp.ecliptical.io/mcp

1. Complete the sign-in and access prompts in the browser, then enable the connector in your chat.

Add the server to Cursor's MCP config — ~/.cursor/mcp.json (global) or .cursor/mcp.json (per-project):

{
  "mcpServers": {
    "voipms": {
      "url": "https://voipms-mcp.ecliptical.io/mcp"
    }
  }
}

1. Reload Cursor. Open Settings → MCP and sign in when prompted to authorize the connection.

VS Code (Copilot agent mode) reads MCP servers from .vscode/mcp.json in your workspace:

{
  "servers": {
    "voipms": {
      "type": "http",
      "url": "https://voipms-mcp.ecliptical.io/mcp"
    }
  }
}

1. Save the file, then click Start on the server in the editor and sign in when prompted.
2. The VoIP.ms tools become available to Copilot in agent mode.

Any client that supports a remote MCP server over the streamable HTTP transport with OAuth can connect. Configure it with:

• Transport: Streamable HTTP (POST). Server-Sent Events are not used.
• URL: https://voipms-mcp.ecliptical.io/mcp
• Auth: OAuth 2.1. The client discovers the authorization server automatically from the protected-resource metadata; no manual client registration is needed.

Claude Desktop starts local MCP servers from its config file. Open it with Settings → Developer → Edit Config and add:

{
  "mcpServers": {
    "voipms": {
      "command": "voipms-mcp"
    }
  }
}

1. Save and restart Claude Desktop. The VoIP.ms tools appear under the tools menu.
2. No sign-in prompt here: you already signed in with voipms-mcp login.

Add the server from the CLI as a local command:

claude mcp add voipms -- voipms-mcp

1. The VoIP.ms tools are available in the next session. There is nothing to authorize: you already signed in with voipms-mcp login.

The ChatGPT desktop app starts local MCP servers through its Codex settings, shared with Codex CLI. ChatGPT on the web can't start a program on your computer; use the hosted server there.

1. Open Settings → MCP servers → Add server.
2. Name it voipms, choose STDIO, and enter the command voipms-mcp.
3. Save, then Restart.

Or add it to ~/.codex/config.toml, which the desktop app, Codex CLI, and the IDE extension all read:

[mcp_servers.voipms]
command = "voipms-mcp"

In ~/.cursor/mcp.json (global) or .cursor/mcp.json (per-project):

{
  "mcpServers": {
    "voipms": { "command": "voipms-mcp" }
  }
}

1. Reload Cursor. The VoIP.ms tools appear under Settings → MCP with no sign-in prompt.

VS Code (Copilot agent mode) reads MCP servers from .vscode/mcp.json in your workspace:

{
  "servers": {
    "voipms": { "type": "stdio", "command": "voipms-mcp" }
  }
}

1. Save the file, then click Start on the server in the editor.
2. The VoIP.ms tools become available to Copilot in agent mode.

Any client that can start a local stdio MCP server can connect. Configure it with:

• Transport: stdio.
• Command: voipms-mcp, with no arguments and no environment variables.
• Auth: none. The client does no OAuth; you already signed in with voipms-mcp login.
