How to connect

Your client connects to the URL. The first time, it asks you to sign in or, for some servers such as GitHub's, to add a token; the repository's README says which.

Terminal

claude mcp add --transport http context7 https://mcp.context7.com/mcp

~/.cursor/mcp.json

{
  "mcpServers": {
    "context7": {
      "url": "https://mcp.context7.com/mcp"
    }
  }
}

~/.codex/config.toml

[mcp_servers.context7]
url = "https://mcp.context7.com/mcp"

Terminal

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

~/.cursor/mcp.json

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

~/.codex/config.toml

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