Cascade → Actions → Open MCP config file (often ~/.config/devin/mcp_config.json). Setup guide

{
  "mcpServers": {
    "context7": {
      "command": "npx",
      "args": [
        "-y",
        "@upstash/context7-mcp"
      ]
    }
  }
}

Run in your terminal: Setup guide

claude mcp add context7 -- npx -y @upstash/context7-mcp

CLI or add to ~/.codex/config.toml. Setup guide

codex mcp add context7 -- npx -y @upstash/context7-mcp

[mcp_servers.context7]
command = "npx"
args = ["-y", "@upstash/context7-mcp"]

Cline panel → Configure MCP Servers, or ~/.cline/data/settings/cline_mcp_settings.json. Setup guide

{
  "mcpServers": {
    "context7": {
      "command": "npx",
      "args": [
        "-y",
        "@upstash/context7-mcp"
      ]
    }

Run the server directly:

npx -y @upstash/context7-mcp

Before you install: Install command taken from the project README. The README mentions API keys or tokens — you'll likely need to add them as environment variables ("env") in the config.
