# WyreUP MCP Server

A production-ready Model Context Protocol (MCP) server that transforms webhook endpoints from automation platforms (n8n, Make.com, Zapier, FlowiseAI, etc.) into reliable, agent-callable tools for **any MCP-compatible AI system**.

**Compatible with:**

- 🤖 **Claude Desktop** (Anthropic's official desktop app)
- 🔧 **Any MCP Client** (VS Code extensions, custom applications, etc.)
- 🌐 **Future MCP Services** (growing ecosystem of MCP-enabled tools)
- 📱 **Custom Integrations** (build your own MCP client)

**📦 NPM Package:** [wyreup-mcp](https://www.npmjs.com/package/wyreup-mcp) (v0.2.6)
**🔗 GitHub Repository:** [tamler/wyreup-mcp](https://github.com/tamler/wyreup-mcp)

## 🎯 What It Does

Turn any HTTP webhook into an MCP tool that AI agents can use reliably. Define your automation endpoints in a simple JSON manifest, and the server handles authentication, retries, rate limiting, health monitoring, and error handling automatically.

## ✨ Key Features

### 🚀 **Enterprise-Ready Reliability**

- **Smart Retry Logic**: Exponential backoff for transient failures
- **Rate Limiting**: Per-tool request throttling with sliding windows
- **Health Monitoring**: Real-time endpoint health tracking and statistics
- **Timeout Management**: Configurable timeouts per tool (great for slow automations)

### 🔐 **Flexible Authentication**

- **Multiple Auth Types**: Header-based and JWT Bearer token authentication
- **Environment Variables**: Secure credential management via `valueFromEnv` and `tokenFromEnv`
- **External Secrets**: Store credentials in `~/.wyreup-secrets/` files
- **Per-Tool Auth**: Each webhook can use different authentication methods

### 🛠 **Developer-Friendly**

- **JSON Schema Validation**: Full input/output schema support with Zod validation
- **Rich Error Handling**: Structured error responses with debugging context
- **Built-in Monitoring Tools**: Health checks and rate limit status via MCP
- **Hot Reload**: Changes to manifest files are picked up automatically

### 🌊 **Advanced HTTP Support**

- **All HTTP Methods**: GET, POST, PUT, PATCH, DELETE support
- **Binary Data**: Handle file downloads and binary responses
- **Streaming Ready**: Architecture prepared for real-time data streams
- **Content Type Detection**: Automatic handling of JSON, text, and binary responses

### 🧠 MCP Protocol Compliance

- ✅ Uses official MCP SDK (v1.12.0+) with full STDIO and SSE support
- ✅ Per-session SSE transports with isolated tool execution
- **Supports transports**: STDIO and SSE
- **Tool Registration**: Fully schema-based using `tools/list` and `tools/call`
- **JSON-RPC 2.0**: Strictly compliant request/response structure

## 🚀 Quick Start

### Installation & Setup

```bash
# Install globally from npm
npm install -g wyreup-mcp

# Or run directly with npx (recommended)
npx wyreup-mcp --init
npx wyreup-mcp --validate
npx wyreup-mcp
```

### ⚡ **Ultra-Fast Setup: Simplified Format**

**NEW**: Get started in under 2 minutes with the simplified webhook format! Perfect for rapid prototyping and low-code users.

```json
{
  "tools": [
    {
      "name": "get_quote",
      "webhook": "https://wyreup.com/tools-mock/random-quote"
    }
  ]
}
```

**That's it!** The system automatically infers:
- ✅ **Description**: "Forward to random quote webhook"
- ✅ **Method**: POST (default for webhooks)
- ✅ **Input Schema**: Empty object `{}`
- ✅ **Output Schema**: Auto-detects JSON, text, binary, or streaming responses

**Supported Response Types:**
- 📄 **JSON** - Auto-parsed for structured data
- 📝 **Text/HTML** - Plain text responses
- 🖼️ **Binary** - Images, PDFs, files (base64 encoded)
- 🌊 **Streaming** - Real-time event streams

**Test immediately:**
```bash
echo '{
  "tools": [
    {
      "name": "get_quote",
      "webhook": "https://wyreup.com/tools-mock/random-quote"
    }
  ]
}' > wyreup-simple.json

echo '{ "jsonrpc": "2.0", "id": "call-1", "method": "tools/call", "params": { "name": "get_quote", "arguments": {} } }' | npx wyreup-mcp --config wyreup-simple.json --transport stdio --debug
```

**Simplified Format Syntax:**
```json
{
  "tools": [
    {
      "name": "your_tool_name",
      "webhook": "https://your-webhook-url.com/endpoint"
    }
  ]
}
```

**Mixed Format Support:** You can combine simplified and full format tools in the same configuration file for maximum flexibility.

### 🚀 **Instant Testing with Live Endpoints**

Skip the setup and test immediately with our live demo endpoints at `wyreup.com`:

```bash
# Create a quick test configuration
echo '{
  "tools": [
    {
      "name": "get_quote",
      "description": "Get an inspirational quote",
      "url": "https://wyreup.com/tools-mock/random-quote",
      "method": "GET",

      }
    }
  ]
}
```

### Connect to MCP Clients

**Claude Desktop:**
Add to your Claude Desktop config (`~/Library/Application Support/Claude/claude_desktop_config.json`):

```json
{
  "mcpServers": {
    "wyreup": {
      "command": "npx",
      "args": ["wyreup-mcp"],
      "cwd": "/path/to/your/project"
    }
  }
}
```

**Other MCP Clients:**

- **VS Code Extensions**: Use MCP extension settings
- **Custom Applications**: Connect via stdio transport on any platform
- **Server Deployments**: Use SSE transport mode (`--transport sse --port 3333`)

The server implements the standard MCP protocol, so it works with any compliant client.

### Authentication Types

**Header Authentication:**

```json
{
  "auth": {
    "type": "header",
    "name": "Authorization",
    "value": "Bearer secret-token"
  }
}
```

**Environment Variable:**

```json
{
  "auth": {
    "type": "header",
    "name": "X-API-Key",
    "valueFromEnv": "API_KEY"
  }
}
```

**JWT Bearer:**

```json
{
  "auth": {
    "type": "jwt",
    "tokenFromEnv": "JWT_TOKEN"
  }
}
```

**External Secrets:**

```json
{
  "authFrom": {
    "user": "production-user"
  }
}
```

Create `~/.wyreup-secrets/production-user.json`:

```json
{
  "tool_name": {
    "type": "header",
    "name": "Authorization",
    "value": "Bearer your-secret-token"
  }
}
```

### Rate Limiting

```json
{
  "rateLimit": {
    "requests": 30, // Max requests
    "window": 60000 // Time window in ms
  }
}
```

## 🖥 Usage

### Command Line Options

```bash
# Validation
npx wyreup-mcp --validate
npx wyreup-mcp --validate --config wyreup-example.json

# Server modes
npx wyreup-mcp                          # STDIO mode (default, used by Claude Desktop and local tools)
npx wyreup-mcp --transport sse         # SSE mode for web clients (experimental)

# Development
npx wyreup-mcp --debug                  # Enable debug logging
npx wyreup-mcp --init                   # Create sample manifest
```

```bash
# SSE Testing (experimental)
npm run test:sse         # Starts local SSE server with demo tools
npm run test:sse-client  # Sends a tool call over SSE transport
```

### Built-in Monitoring

These tools are automatically available and do not require configuration:

- **`health-check`**: Test individual webhook endpoints
- **`health-status`**: Get success rates and performance metrics
- **`rate-limit-status`**: Monitor rate limiting usage

Example: Check health of all tools

```bash
echo '{"jsonrpc": "2.0", "method": "tools/call", "params": {"name": "health-status", "arguments": {}}, "id": 1}' | npx wyreup-mcp
```

### 🧪 SSE Transport Notes

To test SSE locally:

1. Start the server with `--transport sse`
2. Your client must subscribe to `/sse` (EventSource)
3. Wait for the `endpoint` event to get the sessionId
4. Send `POST` requests to `/messages?sessionId=...`
5. Each session gets its own transport and tool server instance
6. Transport is cleaned up after tool execution or connection close
