Render Deployment Guide

This document explains how to deploy the Office Word MCP Server on Render.

Required Environment Variables

Set the following environment variables in your Render service:

MCP_TRANSPORT

• Value: sse
• Description: Sets the transport type to Server-Sent Events (SSE) for HTTP communication
• Required: Yes (for Render deployment)

MCP_HOST

• Value: 0.0.0.0
• Description: Binds the server to all network interfaces
• Required: No (defaults to 0.0.0.0)

FASTMCP_LOG_LEVEL

• Value: INFO
• Description: Sets the logging level for FastMCP
• Required: No (defaults to INFO)

How to Set Environment Variables

1. Go to your Render dashboard: https://dashboard.render.com
2. Navigate to your service: Office-Word-MCP-Server
3. Click on "Environment" in the left sidebar
4. Add the environment variable:
   • Key: MCP_TRANSPORT
   • Value: sse
5. Click "Save Changes"

Deployment

After setting the environment variables:

1. Render will automatically redeploy your service
2. The server will start with SSE transport on the port provided by Render
3. Access your server at: https://your-app.onrender.com/sse

Health Check Endpoint

The FastMCP server with SSE transport automatically provides a health check endpoint at:

• https://your-service.onrender.com/health

Troubleshooting

Server exits with status 1

• Cause: Server is running in STDIO mode instead of SSE
• Fix: Ensure MCP_TRANSPORT=sse is set in environment variables

Port binding errors

• Cause: Server not using Render's PORT environment variable
• Fix: This has been fixed in the latest version of main.py

Cannot connect to server

• Cause: Health checks failing
• Fix: Ensure SSE transport is enabled and server is listening on 0.0.0.0
