Connect by Pasting One Prompt
Paste this into Claude, ChatGPT, Claude Code, or your AI app:
Connect the aVenture MCP server for me: URL https://mcp.aventure.vc/mcp,
transport Streamable HTTP, OAuth sign-in. If you can add it yourself (in
Claude Code, run `claude mcp add --scope user --transport http aventure https://mcp.aventure.vc/mcp`),
do that. Otherwise tell me exactly where to add it in this app.
When it's connected and I've signed in, read aVenture's profile for stripe.com
to confirm it works. Docs: https://docs.aventure.vc/mcp

Ask Your First Question
- "Read aVenture's profile for ramp.com."

Plans and Usage
Profile views, web searches, and research requests count toward your plan's monthly allowance. When one runs out, the answer says which limit you reached and how to upgrade. Ask your assistant to list aVenture plans with monthly and annual prices. You can also manage your plan in subscription settings.
Advanced: Run the Server Locally
Run the server yourself when you need it inside your own network. It requires Node.js 24.18.0 or later.
npm install --global @aventurevc/mcp-server
aventure-mcp-server
The server listens at http://localhost:3333/mcp, which only clients on the same
machine can reach; a cloud app such as ChatGPT cannot. Create a key in
API key settings and have your client send
it with every request:
{
"mcpServers": {
"aventure": {
"type": "http",
"url": "http://localhost:3333/mcp",
"headers": { "Authorization": "Bearer <your-api-key>" }
}
}
}
Store the key in your client's secret storage, not in a file you commit.
AVENTURE_MCP_PORT and AVENTURE_MCP_PATH change the port and route.
