-Tools that interact with B2C Commerce instances (e.g., MRT, SCAPI, cartridge deployment) require credentials, which can be provided via **environment variables**, a **`.env` file**, a **`dw.json` file**, or the **`--config`** flag. Local tools (e.g., scaffolding, development guidelines) work without configuration.
+Different tools require different types of configuration:
+
+| Tool Type | Configuration Required |
+|-----------|----------------------|
+| **MRT tools** (e.g., `mrt_bundle_push`) | API key + project |
+| **B2C instance tools** (e.g., `cartridge_deploy`) | dw.json or instance flags |
+| **Local tools** (e.g., scaffolding) | None |
+
+#### MRT Configuration
+
+MRT tools require an **API key** and **project**. The **environment** is optional (for deployments).
+
+| Setting | Flag | Env Variable | Fallback |
+|---------|------|--------------|----------|
+| API key | `--api-key` | `SFCC_MRT_API_KEY` | `~/.mobify` |
+| Project | `--project` | `SFCC_MRT_PROJECT` | — |
+| Environment | `--environment` | `SFCC_MRT_ENVIRONMENT` | — |
+
+> Priority: Flag > Env variable > `~/.mobify` file
+
+**Example:**
+
+```json
+{
+  "mcpServers": {
+    "b2c-dx": {
+      "command": "/path/to/packages/b2c-dx-mcp/bin/dev.js",
+      "args": [
+        "--toolsets", "MRT",
+        "--project", "my-project",
+        "--environment", "staging",
+        "--api-key", "your-api-key"
+      ]
+    }
+  }
+}
+```
+
+Or use environment variables instead of flags:
+
+```json
+{
+  "mcpServers": {
+    "b2c-dx": {
+      "command": "/path/to/packages/b2c-dx-mcp/bin/dev.js",
+      "args": ["--toolsets", "MRT"],
+      "env": {
+        "SFCC_MRT_API_KEY": "your-api-key",
+        "SFCC_MRT_PROJECT": "my-project",
+        "SFCC_MRT_ENVIRONMENT": "staging"
+      }
+    }
+  }
+}
+```
+
+> **Note:** Make sure the script is executable: `chmod +x /path/to/packages/b2c-dx-mcp/bin/dev.js`
+
+#### Environment-Specific Config
+
+If you have a `~/.mobify` file from the `b2c` CLI, the MCP server will use it as a fallback for API key:
+
+```json
+{
+  "api_key": "your-api-key"
+}
+```
+
+For non-production environments, use `--cloud-origin` to select an environment-specific config file:
+
+| `--cloud-origin` | Config File |
+|------------------|-------------|
+| (not set) | `~/.mobify` |
+| `https://cloud-staging.mobify.com` | `~/.mobify--cloud-staging.mobify.com` |
+| `https://cloud-dev.mobify.com` | `~/.mobify--cloud-dev.mobify.com` |
+
+#### B2C Instance Config (dw.json)
+
+Tools that interact with B2C Commerce instances (e.g., `cartridge_deploy`, SCAPI tools) require instance credentials.
+
+**Authentication Methods:**
+
+| Method | Credentials | Used By |
+|--------|-------------|---------|
+| **Basic auth** | `--username` + `--password` | WebDAV tools (`cartridge_deploy`) |
+| **OAuth** | `--client-id` + `--client-secret` | OCAPI tools, SCAPI tools |
+
+> **Recommendation:** Use Basic auth (username/password) for WebDAV tools like `cartridge_deploy`. OAuth credentials (client-id/client-secret) are required for OCAPI/SCAPI tools. If you need both WebDAV and OCAPI tools, configure all four credentials.
 
 **Priority order** (highest to lowest):
 
-1. Environment variables (`SFCC_*`) — includes `.env` file if present (shell env vars override `.env`)
-2. `dw.json` file (auto-discovered or via `--config`)
+1. Flags (`--server`, `--username`, `--password`, `--client-id`, `--client-secret`)
+2. Environment variables (`SFCC_*`)
+3. `dw.json` file (via `--config` flag or auto-discovery)
 
-#### Option 1: Environment Variables
+**Option A: Flags with Basic auth (for WebDAV tools like cartridge_deploy)**
+
+```json
+{
+  "mcpServers": {
+    "b2c-dx": {
+      "command": "/path/to/packages/b2c-dx-mcp/bin/dev.js",
+      "args": [
+        "--toolsets", "CARTRIDGES",
+        "--server", "your-sandbox.demandware.net",
+        "--username", "your.username",
+        "--password", "your-access-key"
+      ]
+    }
+  }
+}
+```
 
-Set environment variables directly or create a `.env` file in your project root:
+**Option B: Flags with OAuth (for OCAPI/SCAPI tools, or WebDAV fallback)**
 
-```bash
-# .env file or shell exports
-SFCC_HOSTNAME="your-sandbox.demandware.net"
-SFCC_USERNAME="your.username"
-SFCC_PASSWORD="your-access-key"
-SFCC_CLIENT_ID="your-client-id"
-SFCC_CLIENT_SECRET="your-client-secret"
-SFCC_CODE_VERSION="version1"
+```json
+{
+  "mcpServers": {
+    "b2c-dx": {
+      "command": "/path/to/packages/b2c-dx-mcp/bin/dev.js",
+      "args": [

+        "--client-secret", "your-client-secret"
+      ]
+    }
+  }
+}
 ```
 
-#### Option 2: dw.json File
+**Option C: Environment variables (all credentials)**
+
+```json
+{

+        "SFCC_CODE_VERSION": "version1"
+      }
+    }
+  }

+
+**Option D: dw.json with explicit path**
+
+```json
+{

+      "args": ["--toolsets", "CARTRIDGES", "--config", "/path/to/dw.json"]
+    }
+  }
+}
+```
+
+**Option E: dw.json with auto-discovery**
+
+When `--config` is not provided, the MCP server searches upward from `~/` for a `dw.json` file.
 
-Create a `dw.json` file in your project root (auto-discovered by searching upward from current working directory):
+> **Note:** Auto-discovery starts from the home directory, so it won't find project-level `dw.json` files. Use `--config` with an explicit path instead.
