MCP Startup Guide: Building on a Budget
Running a production MCP server on close to $0/month using free hosting tiers, open-source SDKs, and shared auth infra.
Startup storiesCost-saving tips
You don't need an infrastructure budget to ship a real MCP server. The open-source SDKs, free-tier serverless hosting, and community auth patterns cover most early-stage needs.
The $0 Stack
- SDK: official Python or TypeScript SDK (free, open source)
- Hosting: a serverless free tier (Lambda, Cloud Run, or a PaaS free plan) for bursty, low-traffic tool calls
- Auth: API key checked against an environment variable until you have paying users who need scoped access
Where to Spend First
The first real dollar should go to structured logging — debugging a tool-calling failure without logs is the most common early-stage time sink reported in this community.
