Usage with VS Code

For quick installation, use one of the one-click install buttons below...

Manual Installation

For manual installation, add the following JSON block to your User Settings (JSON) file in VS Code. You can do this by pressing Ctrl + Shift + P and typing Preferences: Open Settings (JSON).

Optionally, you can add it to a file called .vscode/mcp.json in your workspace. This will allow you to share the configuration with others.

Note that the mcp key is not needed in the .vscode/mcp.json file.

{
  "mcp": {
    "inputs": [
      {
        "type": "promptString",
        "id": "aws_access_key",
        "description": "AWS Access Key ID",
        "password": true
      },
      {
        "type": "promptString",
        "id": "aws_secret_key",
        "description": "AWS Secret Access Key",
        "password": true
      },
      {
        "type": "promptString",
        "id": "aws_region",
        "description": "AWS Region"
      }
    ],
    "servers": {
      "aws-kb-retrieval": {
        "command": "npx",
        "args": ["-y", "@modelcontextprotocol/server-aws-kb-retrieval"],
        "env": {
          "AWS_ACCESS_KEY_ID": "${input:aws_access_key}",
          "AWS_SECRET_ACCESS_KEY": "${input:aws_secret_key}",
          "AWS_REGION": "${input:aws_region}"
        }
      }
    }
  }
}

For Docker installation:

{
  "mcp": {
