Cline connects to Zephex through its MCP server JSON. Use the stdio config below instead of the older Streamable HTTP setup.
OVERVIEW
Cline is an open-source AI coding agent for VS Code. For Zephex, the reliable setup is the stdio MCP JSON that launches `npx -y zephex` and passes your `ZEPHEX_API_KEY` through the env block.
CONFIG FILE LOCATION
Managed by the Cline extension at ~/Library/Application Support/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json on macOS, %APPDATA%/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json on Windows. You can also configure servers directly from the Cline panel without editing the file.
Open Cline’s MCP Servers editor and paste the JSON exactly as shown.
Replace `mcp_sk_your_key_here` with your real Zephex API key before saving.
{ "mcpServers": { "zephex": { "command": "npx", "args": ["-y", "zephex"], "env": { "ZEPHEX_API_KEY": "mcp_sk_your_key_here" } } }}Confirm the server is connected before relying on Zephex tools in your prompts.
Make sure you saved the JSON through Cline’s MCP server editor and that the top-level key is `mcpServers`.
Click Reconnect in the Cline MCP panel and verify the config uses `command`, `args`, and `env` exactly as shown.
Install Node.js so Cline can launch `npx`, or switch to absolute `node` and package paths if your environment does not inherit PATH correctly.
If the editor still does not connect, return to Quickstart or check Connection Issues.
