What Elixir related stuff are you doing?
As the title says, please share what you’ve been up to with Elixir. Whether that’s been learning it, looking into it, making stuff with it or anything else related to it …we’re a curious bunch here 
I am…
- Checking in on this forum
- Looking out for interesting blogs/posts on Twitter (will cross post any good ones here)
- Going to install Spacemacs
- Then finally, just before it’s time to go to bed - read some more of Programming Elixir

I’ve been working on gen_mcp, MCP server building blocks for Elixir, and just tagged v2.
v2 follows the
2026-07-28protocol revision, announced here, which makes the whole thing stateless. It was a big change and I rewrote a lot of things.It’s still focused on building HTTP servers only, and actually it requires Phoenix right now. It’s not intended to build local stdio MCPs. We use that server to provide MCP servers from our product/internal servers to customers/internal AI tools.
I retrofitted support for protocol versions
2025-06-18and2025-11-25but only to support tool calls as that’s what I have been using mostly. The new protocol implementation supports resources and prompts in addition to tool calls. I never implemented elicitation and sampling (now obsolete) but tool calls supports MRTR.The basic
GenMCPbehaviour is still a generic MCP server that exchanges messages with the built-in “Streamable HTTP” built-in transport. On top of that, the high levelGenMCP.Suitestill covers most use cases with tools, resources and prompts .If anyone feels like building an MCP server with it, I’d be glad to hear how it went. I still need to write some guides, and knowing where people actually get stuck would tell me what to cover.
