1. Add the server

Run in your terminal

codex mcp add context7 --url https://mcp.context7.com/mcp

2. Sign in

Run codex mcp login <name> to complete OAuth for a remote server. Context7 is hosted by Upstash, so there is nothing to install or keep updated.

3. Try it

Ask Codex for something Context7 can do. Pulls current, version-specific library docs and code examples into the prompt. Approve the first tool call and check the result before allowing write actions automatically.

  • · Each server is a [mcp_servers.<name>] table in config.toml.
  • · Use enabled_tools or disabled_tools to keep the tool list short.
