Install one MCP server across Claude Code, Cursor, Codex, and VS Code without manual config edits

Use add-mcp when an agent needs to roll out, list, remove, or synchronize MCP server configs across multiple coding clients instead of hand-editing each config file separately.

Prerequisites

Node.js and npx; one or more supported coding clients such as Claude Code, Codex, Cursor, OpenCode, or VS Code; any required server URLs, auth headers, env vars, or package names.

Installation

Use the upstream install or setup path that matches your environment:

• npx add-mcp url | package name [options]
• npx add-mcp https://mcp.context7.com/mcp
• npx add-mcp find vercel
• npx add-mcp https://mcp.example.com/mcp

Requirements and caveats from upstream:

• Node.js script

• add-mcp supports all three transport types: HTTP, SSE, and stdio. Some agents require type option to be set to specify the transport type. You can use the --type or --transport option to specify the transport type:

Basic usage or getting-started notes:

• bash

• Example installing the Context7 remote MCP server:

• You can add env variables and arguments (stdio) and headers (remote) to the server config using the --env, --args and --header options.
