Connect VNTAR to Codex desktop
Complete these four steps in order. Start with research access; trading access can be granted later from this page.
- 1
Copy the VNTAR server address
This is the only URL you need. Do not paste your VNTAR password or brokerage credentials into Codex.
https://vntar.com/mcp - 2
Add an MCP server in Codex
Open Codex → Settings → MCP servers, choose Add server, and enter:
- Name
- VNTAR
- Type
- Streamable HTTP
- URL
- https://vntar.com/mcp
- 3
Connect and approve in VNTAR
Choose Connect or Save in Codex. A VNTAR sign-in and approval page opens in your browser. Sign in, review the client name and requested access, then approve it. Research-only access is the safest starting point.
- 4
Confirm that Codex appears here
Return to VNTAR → Settings → Agentic trading. You should see an Approved client card named Codex. If it does not appear, refresh this page once and reconnect from Codex.
How you know it worked
Codex is listed above as an approved client, and Codex can answer the safe verification prompt below without asking you to add the server again.
Using ChatGPT instead?
Create a custom MCP app
- 1.In ChatGPT, open Settings → Apps → Advanced settings and enable Developer mode.
- 2.Go to Settings → Apps → Create, paste
https://vntar.com/mcp, then choose Scan tools. - 3.Complete the VNTAR authorization prompt, wait for the scan, and choose Create.
ChatGPT plan and workspace permissions can affect which MCP actions are available.
Open ChatGPT setup helpAfter you connect
Start with a safe connection check.
An approved connection gives your AI workspace permission to use VNTAR when you ask it to. It does not start a background bot or independently look for trades.
Your first Codex prompt
Use the VNTAR MCP tools. Verify my account status, buying power, current positions, and active agentic mandate. Do not submit, cancel, modify, or close any order.When it is active
Open a Codex task with VNTAR enabled and give it a specific request. “Full control ready” means it is permitted to act, not that it is running on its own.
How to follow activity
Trade shows broker orders and fills. Settings shows the client mandate and budget. VNTAR records each MCP request and execution decision securely.
After the check, use a narrow request with a symbol, side, and amount. Every request must still pass your mandate and broker checks; purchase orders also require available buying power.
