MCP - Agent to VSC

Local MCP server that connects an MCP-capable VS Code agent such as Cline to OpenAI and workspace file tools.

Flow

Cline / VS Code -> MCP (stdio) -> local Node.js server -> OpenAI API

Related MCP server: Code MCP Server

Tools

• ask_ai — send prompts to OpenAI

• read_file — read workspace files

• write_file — write workspace files

• list_files — list workspace files/directories

• workspace_info — inspect configuration

Install

Requirements: Node.js 20+.

npm install

Set OPENAI_API_KEY in the environment. Never commit the real key.

PowerShell:

$env:OPENAI_API_KEY="sk-..."
npm start

Cline

Add this server to Cline's MCP settings:

{
  "mcpServers": {
    "mcp-agent-to-vsc": {
      "command": "node",
      "args": ["C:\\path\\to\\mcp-agent-to-vsc\\server.mjs"],
      "env": {
        "OPENAI_API_KEY": "YOUR_API_KEY",
        "OPENAI_MODEL": "gpt-5.6",
        "WORKSPACE_ROOT": "C:\\path\\to\\your\\workspace"
      }
    }
  }
}

For local VS Code MCP configuration, see .vscode/mcp.json.

Security

The server restricts file access to WORKSPACE_ROOT. Keep your API key in an environment variable or an ignored .env file.
