Introducing Docker MCP Catalog and Toolkit: The Simple and Secure Way to Power AI Agents with MCP Tools
Model Context Protocols (MCPs) are quickly becoming the standard for connecting AI agents to external tools, but the developer experience hasn’t caught up. Discovery is fragmented, setup is clunky, and security is too often bolted on last. Fixing this experience isn’t a solo mission—it will take an industry-wide effort. A secure, scalable, and trusted MCP… ⌘ Read more

@kat@yarn.girlonthemoon.xyz At the core, you need an ngircd.conf like this:

[Global]
    Name = your.irc.server.com
    Password = yourfancypassword
    Listen = 0.0.0.0
    Ports = 6667

    AdminInfo1 = Well, me.
    AdminInfo2 = Over here!
    AdminEMail = forget.it@example.invalid

[Options]
    Ident = no
    PAM = no

[SSL]
    CertFile = /etc/ssl/acme/your.irc.server.com.fullchain.pem
    KeyFile = /etc/ssl/acme/private/your.irc.server.com.key
    DHFile = /etc/ngircd/dhparam.pem
    Ports = 6669

Start it and then you can connect on port 6667. (The SSL cert/key must be managed by an external tool, probably something like certbot or acme-client.)

I’m assuming OpenBSD here. Haven’t tried it on Linux lately, let alone Docker. 😅

i am writing a quick little guide on deploying soju/gamja all in docker. because i am bored

@prologic@twtxt.net oooh this looks interesting!!! maybe i could play around with it in docker and see how to integrate it with caddy layer4 for TLS + my existing web client and bouncer!!

hey everyone i’ve spent my whole day trying to set up soju + gamja in docker and now i am down a rabbit hole of building caddy with layer4 support and trying to get TLS for my IRC server and NOTHING IS WORKING

@bender@twtxt.net awww thank you :‘))) you all are too nice!!! i really wanted to share how i did this because i think i’m the first person to publicly attempt a production instance of dreamwidth code in docker, so i’m glad i did a good job at documenting it!!!!!!!

7k words of docs on deploying a livejournal folk. you absolutely want to read 7 thousand words of me forcing dreamwidth into production shape in docker https://stash.4-walls.net/selfhostdw/
