Model Context Protocol (MCP) is “all the rage” these days.

I stumbled upon protoc-gen-go-mcp and think it’s an elegant application of two technologies: programmatically generating an MCP server from a gRPC protobuf.

I’m considering building an MCP server for Ackal but, thought I’d start with something simple: gRPC Health Checking protocol.

I was surprised to learn as I was doing this that there’s a new List (Add List method to gRPC Health service #143) added to grpc.health.v1.Health. My (Ackal) healthcheck server does not yet implement it (see later).

I spent some time over the weekend understanding Fly.io. It’s always fascinating to me how many smart people are building really neat solutions. Fly.io is subtly different to other platforms that I use (Kubernetes, GCP, DO, Linode) and I’ve found the Fly.io team to be highly responsive and helpful to my noob questions.

One of the team’s posts, Docker without Docker surfaced in my Feedly feed (hackernews) and it piqued my interest.
