Webex Calling MCP Server

An MCP (Model Context Protocol) server that lets you manage your entire Webex Calling infrastructure using natural language through an AI assistant like Claude.

Built for Cisco partners and network engineers to demonstrate the power of AI-driven network administration.

Prerequisites

1. Node.js (v18 or later)

Node.js is the runtime needed to execute the MCP server. You must install it on every machine where you want to run the server.

Option A — Installer:

1. Go to nodejs.org and download the LTS version (green button)

2. Open the .pkg file and follow the installer

3. Open Terminal (Spotlight → type "Terminal") and verify:

   node --version
   npm --version

Option B — Homebrew (if you have it):

brew install node

1. Go to nodejs.org and download the LTS version (green button)

2. Run the .msi installer — keep all default options (this adds node and npm to your PATH automatically)

3. Restart your terminal (close and reopen PowerShell or cmd)

4. Verify the installation:

   node --version
   npm --version

Troubleshooting: If npm is not recognized after installation, restart your computer to ensure the PATH is updated.

2. Git

Git is needed to clone this repository.

Git is pre-installed on macOS. Verify with:

git --version

If prompted to install Xcode Command Line Tools, accept the installation.

1. Download Git from git-scm.com

2. Run the installer — keep all default options

3. Restart your terminal and verify:

   git --version

3. A Webex Full Admin account

4. An AI client that supports MCP

Quick Start

1. Clone the repository

Open Terminal and run:

cd ~/Desktop
git clone https://github.com/rochaussee/webex-calling-mcp.git
cd webex-calling-mcp

Open PowerShell and run:

cd $HOME\Desktop
git clone https://github.com/rochaussee/webex-calling-mcp.git
cd webex-calling-mcp

2. Create a Webex Integration

1. Go to developer.webex.com

2. Sign in with your Webex Full Admin account

3. Create a new Integration and note the Client ID and Client Secret

4. Set the Redirect URI to http://localhost:22991/callback

5. Select the required scopes (see src/auth.ts for the default list)

3. Install dependencies & Build

These commands are the same on macOS and Windows:

npm install
npm run build

Note: You must be in the project folder (e.g. cd webex-calling-mcp) before running these commands.

4. Authenticate (one-time setup)

WEBEX_CLIENT_ID=xxx WEBEX_CLIENT_SECRET=yyy npm run auth

On Windows, you must set environment variables separately — the VAR=value command syntax does not work in PowerShell:

$env:WEBEX_CLIENT_ID="xxx"
$env:WEBEX_CLIENT_SECRET="yyy"
npm run auth

Replace xxx and yyy with the Client ID and Client Secret from step 2.

What happens:

1. Your browser opens the Webex login page

2. You sign in with your Webex Full Admin account

3. Webex sends back authentication tokens to the local server

4. Tokens are saved locally:

   • macOS / Linux: ~/.webex-mcp/tokens.json

   • Windows: %USERPROFILE%\.webex-mcp\tokens.json

About tokens:

• Access token (~14 days): used by the MCP server to call Webex APIs

• Refresh token (~90 days): used to automatically renew the access token when it expires

• You only need to re-run npm run auth every ~90 days when the refresh token expires

Useful commands:

npm run auth -- --status # Check token status
npm run auth -- --logout # Clear stored tokens
npm run auth -- --help # Full help

5. Configure in your MCP Client

The MCP server needs your Client ID and Client Secret at runtime to automatically refresh expired access tokens. These are passed as environment variables in the MCP configuration.

Why are Client ID / Secret needed here too? The npm run auth step uses them to obtain tokens. The MCP server config needs them to refresh tokens automatically. Without them, you'd have to re-authenticate manually every ~14 days instead of every ~90 days.

VS Code (Copilot / Claude Dev)

Add to your .vscode/mcp.json or VS Code global settings:

• macOS: ~/Library/Application Support/Code/User/mcp.json

• Windows: %APPDATA%\Code\User\mcp.json

{
 "mcpServers": {
 "webex-calling": {
 "command": "node",
 "args": ["/Users/<your-username>/Desktop/webex-calling-mcp/dist/index.js"],
 "env": {
 "WEBEX_CLIENT_ID": "your-integration-client-id",
 "WEBEX_CLIENT_SECRET": "your-integration-client-secret"
 }
 }
 }
}

{
 "mcpServers": {
 "webex-calling": {
 "command": "node",
 "args": ["C:\\Users\\<your-username>\\Desktop\\webex-calling-mcp\\dist\\index.js"],
 "env": {
 "WEBEX_CLIENT_ID": "your-integration-client-id",
 "WEBEX_CLIENT_SECRET": "your-integration-client-secret"
 }
 }
 }
}

Note: Use double backslashes \\ in JSON paths on Windows.

Security note: This file is local to your machine and not tracked by git. Never commit your credentials.

Claude Desktop

Add to your Claude Desktop config:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

• Windows: %APPDATA%\Claude\claude_desktop_config.json

{
 "mcpServers": {
 "webex-calling": {
 "command": "node",
 "args": ["/Users/<your-username>/Desktop/webex-calling-mcp/dist/index.js"],
 "env": {
 "WEBEX_CLIENT_ID": "your-integration-client-id",
 "WEBEX_CLIENT_SECRET": "your-integration-client-secret"
 }
 }
 }
}

{
 "mcpServers": {
 "webex-calling": {
 "command": "node",
 "args": ["C:\\Users\\<your-username>\\Desktop\\webex-calling-mcp\\dist\\index.js"],
 "env": {
 "WEBEX_CLIENT_ID": "your-integration-client-id",
 "WEBEX_CLIENT_SECRET": "your-integration-client-secret"
 }
 }
 }
}

6. Start Talking to Your Infrastructure

Once configured, restart VS Code or Claude Desktop, then just ask questions in natural language. The AI will automatically pick the right MCP tools.

• SDK: @modelcontextprotocol/sdk (official MCP TypeScript SDK)

• API Client: Typed wrapper around Webex REST API v1

• Auth: OAuth2 Integration (Client ID / Client Secret) with auto-refresh

Development

# Run in development mode (no build step)
WEBEX_CLIENT_ID=xxx WEBEX_CLIENT_SECRET=yyy npx tsx src/index.ts

# Build for production
npm run build

# Run production build
WEBEX_CLIENT_ID=xxx WEBEX_CLIENT_SECRET=yyy node dist/index.js

# Set environment variables (do this once per terminal session)
$env:WEBEX_CLIENT_ID="xxx"
$env:WEBEX_CLIENT_SECRET="yyy"

# Run in development mode
npx tsx src/index.ts

# Build for production
npm run build

# Run production build
node dist/index.js

Security Notes

• Never commit your Client ID / Client Secret — always use environment variables

• Tokens are stored locally in ~/.webex-mcp/tokens.json (macOS/Linux) or %USERPROFILE%\.webex-mcp\tokens.json (Windows) with restricted permissions

• Token scope requirements depend on which tools you use:

  • spark-admin:people_read — people listing

  • spark-admin:telephony_config_read / _write — calling config

  • spark-admin:calling_cdr_read — call history/CDR

  • spark-admin:devices_read — device inventory
