+# MCP REST API Tester Plugin
+
+This plugin automatically configures the [dkmaker-mcp-rest-api](https://github.com/dkmaker/mcp-rest-api) MCP server for Claude Code.
+
+## What This Plugin Does
+
+When installed, this plugin adds the REST API tester MCP server to Claude Code, enabling you to test HTTP endpoints directly from conversations with Claude.
+
+## Installation
+
+```bash
+/plugin install mcp-rest-api@my-claude-plugins
+```
+
+Or from the terminal:
+```bash
+claude plugin install mcp-rest-api@my-claude-plugins
+```
+
+## Configuration
+
+The plugin uses environment variables with the `REST_MCP_` prefix to avoid conflicts with other tools.
+
+### Configuration Template
+
+Copy this template to your settings file and uncomment/configure the variables you need:
+
+```json
+{
+  "env": {
+    "REST_MCP_BASE_URL": "https://api.example.com",
+
+    // Authentication - choose ONE method:
+
+    // Option 1: Bearer Token
+    // "REST_MCP_AUTH_BEARER": "YOUR_BEARER_TOKEN_HERE",
+
+    // Option 2: Basic Auth
+    // "REST_MCP_AUTH_USERNAME": "YOUR_USERNAME_HERE",
+    // "REST_MCP_AUTH_PASSWORD": "YOUR_PASSWORD_HERE",
+
+    // Option 3: API Key
+    // "REST_MCP_APIKEY_HEADER": "X-API-Key",
+    // "REST_MCP_APIKEY_VALUE": "YOUR_API_KEY_HERE",
+
+    // Optional settings:
+    // "REST_MCP_SSL_VERIFY": "true",
+    // "REST_MCP_RESPONSE_LIMIT": "10000",
+
+    // Custom headers (optional):
+    // "HEADER_X-API-Version": "2.0",
+    // "HEADER_Accept": "application/json",
+    // "HEADER_Authorization": "custom-auth-value"
+  }
+}
+```
+
+### Option 1: Shell Environment (Recommended)
+
+Set environment variables before starting Claude Code:
+
+```bash
+# In your ~/.bashrc or ~/.zshrc
+export REST_MCP_BASE_URL="https://your-api.com"
+export REST_MCP_AUTH_BEARER="YOUR_BEARER_TOKEN_HERE"
+
+# Or for one session
+REST_MCP_BASE_URL="http://localhost:3000" claude
+```
+
+### Option 2: Project Settings
+
+Edit `.claude/settings.json` in your project and paste this template:
+
+```json
+{
+  "env": {
+    "REST_MCP_BASE_URL": "http://localhost:3000",
+
+    // Authentication - choose ONE method:
+
+    // Option 1: Bearer Token
+    // "REST_MCP_AUTH_BEARER": "YOUR_BEARER_TOKEN_HERE",
+
+    // Option 2: Basic Auth
+    "REST_MCP_AUTH_USERNAME": "YOUR_USERNAME_HERE",
+    "REST_MCP_AUTH_PASSWORD": "YOUR_PASSWORD_HERE",
+
+    // Option 3: API Key
+    // "REST_MCP_APIKEY_HEADER": "X-API-Key",
+    // "REST_MCP_APIKEY_VALUE": "YOUR_API_KEY_HERE",
+
+    // Optional settings:
+    // "REST_MCP_SSL_VERIFY": "false",
+    // "REST_MCP_RESPONSE_LIMIT": "50000"
+  }
+}
+```
+
+### Option 3: User Settings (All Projects)
+
+Edit `~/.claude/settings.json` and paste this template:
+
+```json
+{
+  "env": {
+    "REST_MCP_BASE_URL": "https://api.production.com",
+
+    // Authentication - choose ONE method:
+
+    // Option 1: Bearer Token
+    "REST_MCP_AUTH_BEARER": "YOUR_PRODUCTION_TOKEN_HERE",
+
+    // Option 2: Basic Auth
+    // "REST_MCP_AUTH_USERNAME": "YOUR_USERNAME_HERE",
+    // "REST_MCP_AUTH_PASSWORD": "YOUR_PASSWORD_HERE",
+
+    // Option 3: API Key
+    // "REST_MCP_APIKEY_HEADER": "X-API-Key",

+
+    // Optional settings:
+    "REST_MCP_SSL_VERIFY": "true",
+    "REST_MCP_RESPONSE_LIMIT": "10000"
+  }
+}
+```
+
+## Environment Variables Reference
+
+All variables use the `REST_MCP_` prefix to avoid naming conflicts.
+
+| Variable | Maps to MCP Server | Description | Default |
+|----------|-------------------|-------------|---------|
+| `REST_MCP_BASE_URL` | `REST_BASE_URL` | Base URL for API requests | `https://api.example.com` |
+| `REST_MCP_AUTH_BEARER` | `AUTH_BEARER` | Bearer token authentication | None |
+| `REST_MCP_AUTH_USERNAME` | `AUTH_BASIC_USERNAME` | Basic auth YOUR_USERNAME_HERE | None |
+| `REST_MCP_AUTH_PASSWORD` | `AUTH_BASIC_PASSWORD` | Basic auth YOUR_PASSWORD_HERE | None |
+| `REST_MCP_APIKEY_HEADER` | `AUTH_APIKEY_HEADER_NAME` | API key header name | None |
+| `REST_MCP_APIKEY_VALUE` | `AUTH_APIKEY_VALUE` | API key value | None |
+| `REST_MCP_SSL_VERIFY` | `REST_ENABLE_SSL_VERIFY` | Enable SSL verification | `true` |
+| `REST_MCP_RESPONSE_LIMIT` | `REST_RESPONSE_SIZE_LIMIT` | Max response size (bytes) | `10000` |
+
+**Custom Headers**: Use the `HEADER_*` prefix directly (not `REST_MCP_`):
+```bash
+export HEADER_X-API-Version="2.0"
+export HEADER_Accept="application/json"
+```
+
+## Quick Start Examples
+
+### Testing a Local API
+
+```bash
+# Configure for local development
+export REST_MCP_BASE_URL="http://localhost:3000"
+export REST_MCP_AUTH_BEARER="dev-token"
+
+# Start Claude Code
+claude
+
+# Ask Claude to test endpoints
+> Test the GET /users endpoint
+> Make a POST to /auth/login with email and YOUR_PASSWORD_HERE
+```
+
+### Testing a Production API
+
+```bash
+# Configure for production
+export REST_MCP_BASE_URL="https://api.production.com"
+export REST_MCP_AUTH_BEARER="YOUR_BEARER_TOKEN_HERE"
+export REST_MCP_SSL_VERIFY="true"
+
+claude
+```
+
+### Using Basic Auth
+
+```bash
+export REST_MCP_BASE_URL="https://api.example.com"
+export REST_MCP_AUTH_USERNAME="YOUR_USERNAME_HERE"
+export REST_MCP_AUTH_PASSWORD="YOUR_PASSWORD_HERE"
+
+claude
+```
+
+### Using API Key
+
+```bash
+export REST_MCP_BASE_URL="https://api.example.com"
+export REST_MCP_APIKEY_HEADER="X-API-Key"
+export REST_MCP_APIKEY_VALUE="YOUR_API_KEY_HERE"
+
+claude
+```
+
+## Authentication Methods
+
+The MCP server supports multiple authentication methods. Configure only one:
+
+| Method | Variables |
+|--------|-----------|
+| **Bearer Token** | `REST_MCP_AUTH_BEARER` |
+| **Basic Auth** | `REST_MCP_AUTH_USERNAME` + `REST_MCP_AUTH_PASSWORD` |
+| **API Key** | `REST_MCP_APIKEY_HEADER` + `REST_MCP_APIKEY_VALUE` |
+
+## Usage
+
+Once installed and configured, ask Claude to test REST endpoints:
+
+```
+Test the GET /users endpoint
+Make a POST request to /auth/login with {"email": "test@example.com", "password": "your-password"}
+What does the /api/status endpoint return?
+Check if the /health endpoint is responding
+Send a PUT request to /users/123 to update the user
+```
+
+Claude will automatically use the `test_request` tool from the MCP server.
+
+## Troubleshooting
+
+### MCP server not appearing
+
+After installation, restart Claude Code:
+```bash
+# Exit Claude Code (Ctrl+D or /exit)
+# Start it again
+claude
+
+# Check if server is loaded
+/mcp
+```
+
+You should see "rest-api" in the list.
+
+### Environment variables not working
+
+1. Set the env vars **before** starting Claude Code
+2. Or configure them in `settings.json`
+3. **Restart Claude Code** after changing settings
+
+Check your current env vars:
+```bash
+env | grep REST_MCP
+```
+
+### NPM package not found
+
+The plugin uses `npx -y dkmaker-mcp-rest-api` which downloads the package on first use.
+
+Requirements:
+- Node.js 18+ installed
+- Internet connection for first run
+
+## Uninstall
+
+```bash
+/plugin uninstall mcp-rest-api@my-claude-plugins
+```
+

 ## Installation
 
+Choose one of the following methods:
+
+### Option 1: Claude Code Plugin (Recommended)
+
+Install via the my-claude-plugins marketplace for automatic configuration:
+
+```bash
+# In Claude Code
+/plugin marketplace add dkmaker/my-claude-plugins
+/plugin install mcp-rest-api@my-claude-plugins
+```
+
+Then configure with environment variables (see [PLUGIN.md](PLUGIN.md) for details):
+
+```bash
+export REST_MCP_BASE_URL="https://your-api.com"
+export REST_MCP_AUTH_BEARER="your-token"
+claude
+```
+
+### Option 2: Manual MCP Server Configuration
+
+Add the MCP server directly using the `claude mcp add` command:
+
+```bash
+# Basic setup (no authentication)
+claude mcp add --transport stdio rest-api -- npx -y dkmaker-mcp-rest-api
+
+# With Bearer token authentication
+claude mcp add --transport stdio \
+  --env REST_BASE_URL=https://api.example.com \
+  --env AUTH_BEARER=your-token \
+  rest-api -- npx -y dkmaker-mcp-rest-api
+
+# With Basic authentication
+claude mcp add --transport stdio \
+  --env REST_BASE_URL=https://api.example.com \
+  --env AUTH_BASIC_USERNAME=admin \
+  --env AUTH_BASIC_PASSWORD=secret \
+  rest-api -- npx -y dkmaker-mcp-rest-api
+
+# With API Key authentication
+claude mcp add --transport stdio \
+  --env REST_BASE_URL=https://api.example.com \
+  --env AUTH_APIKEY_HEADER_NAME=X-API-Key \
+  --env AUTH_APIKEY_VALUE=your-key \
+  rest-api -- npx -y dkmaker-mcp-rest-api
+```
+
+### Option 3: NPM Global Install (For Cline and other MCP clients)
+
 Install the package globally:
 ```bash
 npm install -g dkmaker-mcp-rest-api
 ```
 
-## Configuration
+Then configure your MCP client. See the [Configuration](#configuration) section below for client-specific setup.
