Codex CLI#

Connect ClipKit to OpenAI Codex — the codex terminal agent — so it can author and preview ClipKit videos while it codes.

ClipKit's connector is open (no key, no OAuth) and speaks Streamable HTTP at https://www.clipkit.dev/mcp. Sessionless servers like ClipKit are the easy case for Codex.

Add the connector#

codex mcp add clipkit --url https://www.clipkit.dev/mcp

Or hand-edit ~/.codex/config.toml:

[mcp_servers.clipkit]
url = "https://www.clipkit.dev/mcp"
# optional — bump these if a cold start is slow:
startup_timeout_sec = 20
tool_timeout_sec = 120

Verify#

codex mcp list should show clipkit with its URL. Start codex, run /mcp (or ask it to list MCP tools), and confirm the ClipKit tools appear.

Notes#

  • Use url only — don't mix url with command / args in the same block; Codex's parser rejects it.
  • Default timeouts are 10s startup / 60s per tool. If a cold start or a slow tool times out, raise startup_timeout_sec / tool_timeout_sec.
  • On older Codex builds, remote URL servers are gated behind a top-level key — add experimental_use_rmcp_client = true above the [mcp_servers.clipkit] block (not inside it), or just update Codex.
