FAQ
What is the best free deployment MCP server?
Azure MCP (Microsoft) ranks first with a TestedMCP score of 100/100 (tested 2026-10-22). Ties are broken by GitHub stars; affiliate status is never used.
Do I need an API key?
Azure MCP (Microsoft): no key needed for the MCP handshake; mcp-remote (proxy): no key needed for the MCP handshake; Kubernetes (Flux159): no key needed for the MCP handshake; Heroku (official): no key needed for the MCP handshake; Netlify (official): no key needed for the MCP handshake. A working handshake without a key doesn't mean the backing service is free.
Is AWS Core (AWS Labs) deprecated?
Yes. Status: "yanked: load individual MCPs" (tested 2026-10-22).
Is Railway (official) deprecated?
Yes. Status: "Deprecated: Railway MCP is now bundled into the Railway CLI. Use 'railway mcp'. See https://docs.railway.com/cli/mcp." (tested 2026-10-22).
Is AWS KB Retrieval (legacy reference) deprecated?
Yes. Status: "Package no longer supported. Contact Support at https://www.npmjs.com/support for more info." (tested 2026-10-22).
What's the difference between free and free tier?
Free means open source with no paid service behind it. Free tier means the server is open source but the API behind it meters usage, and heavy use is paid.
