Connect VNTR OS to your AI client

Use VNTR OS from a client that supports remote MCP over Streamable HTTP and OAuth. Your connection operates on the organization you authorize in VNTR OS. Investors and startups receive different tool lists; account permissions still apply to every action.

Before you connect

You need a VNTR OS account, membership in the organization you want to use, and access to MCP for that organization. Some actions require additional account permissions. The connector does not transfer funds or execute investment trades.

Connect

  1. In your AI client's remote MCP or custom connector settings, enter https://mcp.vntr.vc/.
  2. Start the OAuth connection. Sign in on the VNTR OS consent page using your usual method. If your account already has a password, you can select Sign in with password.
  3. Check the organization displayed on the consent page. Choose read-only access, or read and write access if your client requested it, then approve.
  4. Return to your AI client and ask it to list what it can do with VNTR OS.

Do not paste passwords, sign-in codes, API tokens or other credentials into chat or tool arguments. OAuth delivers the connection credential directly to your client.

Try it

For an investor account:

  • “Show my current investment thesis.” (get_thesis)
  • “List the deals in my pipeline.” (list_deals)
  • “Show my portfolio holdings.” (list_portfolio_holdings)

For a startup account:

  • “Read my company profile.” (read_startup_profile)
  • “List my fundraising contacts.” (list_fundraising_contacts)
  • “Show my cap table.” (get_cap_table)

Write tools can change records, start analysis jobs or send information to recipients. Read each action before approving it in your client. Confirmation behavior depends on your client; a write-enabled connection is permission to execute authorized writes. Use read-only access if you do not want the client to make changes.

Connection lifetime and revocation

New OAuth connections expire after one year. Reconnect and approve access again when prompted; automatic refresh is not currently offered. To stop access earlier, revoke the connection in Settings → API tokens in VNTR OS, then remove the connector from your AI client. Deleting the client-side connection alone may not revoke its credential. Manually issued API tokens follow the expiry configured when they were created.

Data and privacy

Tools return the data needed for the requested task: for example your thesis, company profile, deal information, portfolio, fundraising contacts or cap table. Those results are delivered to the AI client you connected. Its handling of the results is governed by that provider's terms and your account settings.

VNTR OS records tool-call audit metadata for accountability. Disconnecting stops future access; it does not remove data already returned to the client or delete VNTR OS records. See our Privacy Policy for collection, processors, retention and deletion requests, and our Terms for service conditions.

Troubleshooting

  • Sign-in requested again: the connection may have expired or been revoked. Reconnect from your AI client and check the organization on the consent page.
  • Write refused: use read-only tools, or reconnect and approve write access if intended.
  • Account access refused: check your organization membership and permissions with your administrator. A connection cannot give you access to another organization's records.
  • Too many requests: pause and retry after the server's indicated delay.
  • Connection cannot be completed: verify the URL above and that your client supports remote MCP and OAuth. Contact info@vntr.vc with your client name, the time of the failure and the error message. Do not include tokens or passwords.
