🚀 Quick Start & MCP Configuration

EnvMem is designed to work seamlessly with any MCP-compatible client (like Claude Desktop, Cursor, or your own tools).

Option 1: Claude Desktop (Recommended)

Add this to your claude_desktop_config.json:

{
  "mcpServers": {
    "envmem": {
      "command": "npx",
      "args": ["-y", "envmem"],
      "env": {
        "ENVMEM_API_KEY": "your-secret-api-key"
      }
    }
  }
}

Note: Generate your API key at envmem.com or use any random string (it acts as your personal partition).

Option 2: Remote MCP (No Node.js required)

If your MCP client supports remote URLs (SSE), you can connect directly without running anything locally:

{
  "mcpServers": {
    "envmem": {
      "url": "https://envmem.com/mcp?apikey=your-secret-api-key"
    }
  }
}

Usage

1. Import Your Variables

import_env_variables({
  envText: `
    OPENAI_API_KEY=sk-...
    STRIPE_SECRET_KEY=sk_live_...
    DATABASE_URL=postgres://...
  `
})

2. Create a Project

create_project({
  name: "my-saas",
  repoUrl: "github.com/me/my-saas",
  tags: ["nextjs", "stripe", "supabase"]
})

3. Link Services to Project

link_services_to_project({
  projectName: "my-saas",
  services: ["Stripe", "Supabase", "OpenAI", "Clerk"]
})

4. Get Complete .env File

get_envs_for_project({
  projectName: "my-saas",
  environment: "prod"
})
// Returns ready-to-use .env file content

5. Auto-Fill from .env.example

fill_env_example({
  envExampleContent: `OPENAI_API_KEY=\nSTRIPE_SECRET_KEY=\nDATABASE_URL=`,
  projectName: "my-saas"
})
// Returns filled .env with your stored values

Project Management

Typical Workflow

// 1. Import your envs once
import_env_variables({ envText: "..." })

// 2. Create project
create_project({ name: "autoclient", repoUrl: "github.com/me/autoclient" })

// 3. Link services
link_services_to_project({
  projectName: "autoclient",
  services: ["Stripe", "Supabase", "OpenAI"]
})

// 4. Get .env for deployment
get_envs_for_project({ projectName: "autoclient", environment: "prod" })

• Bearer: Authorization: Bearer your-key

• Query: ?apikey=your-key
