Set up Weaviate MCP in VS Code

Connect to Weaviate vector database collections for semantic search, knowledge base operations, and chat memory storage from your AI editor.

1

Locate the config file

VS Code reads MCP server configuration from the following file:

.vscode/settings.json → mcp section

Create this file if it does not already exist. For VS Code, this is inside your workspace .vscode/settings.json file under the mcp section.

2

Add the configuration

Add the following to your VS Code config file:

json
{
  "servers": {
    "weaviate-mcp": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "mcp-server-weaviate"
      ],
      "env": {
        "WEAVIATE_URL": "YOUR_WEAVIATE_URL",
        "WEAVIATE_API_KEY": "YOUR_WEAVIATE_API_KEY"
      }
    }
  }
}

WEAVIATE_API_KEYOptional
