Connect to Codex CLI

​

Prerequisites

• Codex CLI installed (npm install -g @openai/codex)
• A V5 bearer token — get one from POST /admin/tokens/issue

​

Setup

{
  "mcpServers": {
    "ascend": {
      "type": "http",
      "url": "https://ascend-gateway-v5.ascendgtm.workers.dev/mcp",
      "headers": {
        "Authorization": "Bearer ${ASCEND_GATEWAY_TOKEN}"
      }
    }
  }
}

export ASCEND_GATEWAY_TOKEN=<your-token>
# Add to ~/.zprofile to persist

codex "What are my top HubSpot deals by amount?"

​

TOML config (alternative)

[mcpServers.ascend]
type = "http"
url = "https://ascend-gateway-v5.ascendgtm.workers.dev/mcp"

[mcpServers.ascend.headers]
Authorization = "Bearer ${ASCEND_GATEWAY_TOKEN}"

​

Agentic mode with V5

codex --full-auto "Pull last week's Google Ads performance, identify the top 3 campaigns by ROAS, and write a summary I can paste into Slack."

​

Notes

• Codex has no session hook — manually update HANDOVER.md after multi-step sessions
• Bearer token auth (no OAuth flow) — suitable for scripts and CI
