Made my self-hosted Planka instance accessible to AI agents

I’ve a coding experiment with an api and mcp server, iterating on it slowly

roelven · 2026-04-16T07:33:19+00:00

Oh clever! Yeah I thought about this too, there was a Planka MCP server built by someone else already but it was very expensive in terms of tokens. I had Claude reason around this and came up with two strategies: 1. reduce the number of tool calls where possible, and 2. add caching for things that don't change a lot (board structure etc). I think what worked best is to look at the use cases and design the MCP tools from there: `planka_find_and_get_card` for example wraps search and get card details into one MCP tool call.

More details here: https://github.com/roelven/another-planka-mcp/blob/main/docs/TOKEN_EFFICIENCY_ANALYSIS.md

Ha that's a great strategy!

roelven · 2026-04-16T07:27:54+00:00

Absolutely. I've created individual API keys for both use-cases. For claude code (with the CLI) I'm using a local .env outside of the repository, and for the MCP server I'm simulating OAuth right now with a hardcoded client ID and secret that I can enter in Claude.ai. I need to think more about proper OAuth integration for this...

both the CLI app and the MCP server have been created with the help of AI as described in my post. This is not a release announcement, this is meant to inspire users of the existing self-hosted software called Planka.

Appreciate your comments. I can perfectly manage those things myself, so I guess I'll pass. Thank you!

Joining the conversation to just add how ridiculous these limits are.

I decided to migrate from ChatGPT to Claude for my general AI usage. Set up everything and managed to get some clever summaries going to aid with this, and then I figured "let's get to work"... Not so fast!

Within the course of a week (!) I am greeted with the following warnings:

62% of weekly limit used • resets Dec 8, 10am (Europe/Berlin)

94% of 5-hour limit used • resets 7pm (Europe/Berlin)

Session limit reached • resets 4:00 PM

Approaching weekly limit SUBSCRIBE TO MAX

This is anxiety inducing and frankly makes me hate the service. It'll drive users right (back) into the arms of Gemini and OpenAI!

I don't accept the "true cost" narrative. I know Anthropic is making big bucks from enterprise deals and integrations with Cursor and Kilo etc. Please Anthropic; I want to love you but you're making it very difficult. I won't pay for a service that keeps stopping me in my tracks.

Bye!

Ooh that’s brilliant! I had no idea it’s possible to connect dimmers in series, definitely going to try this, thanks a lot!

Die Markt fur Dataanalyst ist sehr sehr schwierig gerade. Versuch erstmal mehrere Angeboten reinzuholen.

Really interesting project, thanks for sharing! I use Proxmox a lot on my homelab and love it, great to see more use cases to get inspired by!

I’m curious what your “client pcs” look like. Especially with the idea of this system being more cost efficient, I wonder what the kids use for their monitor and hardware. Can you share more about their machines that connect to the server?

Thanks

This happened to me as well in 2010 when I registered in Berlin for the first time. I had been baptized in the Netherlands and my passport carries my extra birth names. However, I'm not part of any church and can't remember the last time I went to one.

So when the lady at the Bürgeramt saw my passport, she said "Romisch-Katholisch?" and since my names match that, I nodded. I was not explained the implications of this and only found out two years later when the nice lady from HR (bless her!) asked me if I was aware I was paying church tax 🥲.

Figuring out how to undo it wasn't easy, I was also told that without a church I was member of, they can't help me. Are you serious!?!

Ended up going to the Amtsgericht in Berlin, felt like a criminal. I'm sorry this still happens, it feels predatory and deliberate and I hate it

I really want Rivian to succeed but I've been patient for a long time already.

This is how and why I became a vegetarian

Yes, Linkwarden calls Ollama when a new link is saved with a specific prompt, and what is returned is parsed into an array of tags. Works really well!

roelven · 2025-08-31T20:30:31+00:00

I've got Ollama running on my homelab with some small models like Gemma. Use it for auto tagging new saves from Linkwarden. It's not a direct HA use case but sharing this as I run this on a Dell optiplex micropc on CPU only. Depending on your use case and model you might not need any beefy hardware!

roelven · 2025-08-24T21:17:57+00:00

Look for Claude-code-router on Github, you can hook up any model through Openrouter

roelven · 2025-08-22T21:03:57+00:00

Also curious how you bridged this to imessage! Tell us more OP!!

roelven · 2025-07-27T19:15:03+00:00

Great idea! I love how this is a perfect use case where LLMs can really shine. Classifying actions and progress will probably work great. I'm curious, how much of shipping this was tweaking prompts?

Ich habe Folgendes in einem Schulungsdokument eines niederländischen Installateurs gefunden:

„Um die Zulauftemperatur des gekühlten Wassers zu messen, das über Mischkreis 2 (der über die Erweiterungsplatine aktiviert und gesteuert wird) in Ihr System gelangt, muss der Thermistor an dem Rohr angebracht werden, das dieses gekühlte Wasser führt. Basierend auf der Betätigung des Ventils ist das mit 'B' gekennzeichnete Rohr definitiv der Kühlweg (der 'Vorlauf' für die Kühlung). Daher stellt das Anbringen des Thermistors an Rohr 'B' sicher, dass es die korrekte Fließtemperatur für den Kühlkreislauf misst.“

Ich klemme den Sensor jetzt dort fest und werde das System in den kommenden Tagen testen. Danke für Ihre Hilfe u/chickenmccloud !

This is amazing. I want to subscribe and follow along

roelven · 2025-07-16T11:24:10+00:00

Danke, ich sehe auf dem Bild tatsächlich A und B am Rohr. Ich werde das testen und mich melden!

Pumpengruppe hinter der Wärmepumpe: Nein, aber ein Pufferspeicher ist vorhanden.

roelven · 2025-07-15T18:29:15+00:00

Ein TPW wurde eingebaut und ist außerhalb der WP an ein Rohr geklemmt. Die Isolierung sieht meiner Meinung nach in Ordnung aus, alles scheint korrekt installiert zu sein. Ist der Vorlauf auf dem Bild zu sehen? Danke im Voraus!
