This guide shows how to configure OpenCode to use Grapevine for company context.

​
Prerequisites

  • An OpenCode installation
  • A Grapevine account with API access

​
Setup

OpenCode does not yet support Oauth for Remote MCP servers. Therefore, we will use mcp-remote as a workaround, so we don’t have to hardcode any API credentials.

​
1. Configure MCP server

First, add the MCP server to your OpenCode configuration:
opencode.json
{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "grapevine": {
      "type": "local",
      "command": ["npx", "-y", "mcp-remote", "https://mcp.getgrapevine.ai"]
    },
  },
}

​
2. Authentication

Login manually once so that OpenCode picks up your credentials: 
npx -y mcp-remote https://mcp.getgrapevine.ai
Your browser will open, login with the same account you use to access your Grapevine dashboard.

​
3. Test the connection

Restart OpenCode and verify the connection by asking a question that requires company context: 
Use the grapevine mcp. What authentication patterns do we use in our codebase?
