Add the Claude Platform Docs MCP server to Codex
Add the Claude Platform Docs entry the way Codex’s own docs describe, fill in what it needs, then check it’s connected.
Run the command
codex mcp add anthropic-claude-platform-docs --url https://platform.claude.com/docs/mcpCheck it’s connected
Restart or reload Codex and look for anthropic-claude-platform-docs in its list of MCP servers. A server that needs sign-in opens it on first use.
