Next Round MCP server

Connect Claude, ChatGPT, Cursor or any MCP client to Next Round. Agents can search the investor database and, once the founder signs in, manage their shortlist on their behalf.

Connecting

Endpoint: https://nextround.vc/mcp
Transport: MCP Streamable HTTP
Auth: OAuth 2.1 with dynamic client registration. Clients discover it at /.well-known/oauth-protected-resource; you approve access on a consent screen after signing in.
Scope: Tools act as the signed-in user — shortlist reads and writes are limited to that account.

Example client config:

{
  "mcpServers": {
    "next-round": {
      "url": "https://nextround.vc/mcp"
    }
  }
}
