BestReads Server

This is a remote MCP server, built on Cloudflare Workers, that provides personalized book recommendation.

This was built using Cloudflare's guide on deploying remote MCP servers. It uses the Agents SDK to build the MCP server, Durable Objects to persist the user's book preferences, Workers AI to generate book recommendations, and Cloudflare's OAuth Provider library to add GitHub as an authentication provider. The MCP server supports Server-Sent Events (/sse) and Streamable HTTP (/mcp) transport methods.

Get Started

To try it out, connect to https://bestreads.dinas.workers.dev/sse or https://bestreads.dinas.workers.dev/mcp, if your MCP client supports Streamable HTTP. Or, deploy it yourself using the Deploy to Cloudflare button + instructions below.
