• Legacy SSE endpoint: /sse

Quick Start (Koyeb First)

1. Fork or use this repo on GitHub

Use this repository in your own GitHub account (for example RunLittleTurtle/mcp-coda).

2. Create a Koyeb account and connect GitHub

In Koyeb:

1. Create a new Web service
2. Select your GitHub repo and main branch
3. Keep Buildpack as builder
4. Choose Free / CPU Eco instance

3. Set environment variables

Add these variables in Koyeb:

• API_KEY = your Coda API key
• PORT = 3000

4. Configure port

In Koyeb Ports:

• Port: 3000

Important:

• Use /mcp (not / and not /sse in Agent Builder)

pnpm install
pnpm build
echo "API_KEY=your-coda-key" > .env
PORT=3000 pnpm start:http

Then test:
