MCP support is available via the fast_mcp extension: https://llmspy.org/docs/mcp/fast_mcp

I use llms .py as a personal assistant and MCP is required to access tools available via MCP.

MCP is a great way to make features available to AI assistants, here's a couple I've created after enabling MCP support:

- https://llmspy.org/docs/mcp/gemini_gen_mcp - Give AI Agents ability to generate Nano Banana Images or generate TTS audio

- https://llmspy.org/docs/mcp/omarchy_mcp - Manage Omarchy Desktop Themes with natural language

I will say there's a noticable delay in using MCP vs tools, where I ended up porting Anthropic's node filesystem MCP to Python [1] to speed up common AI Assistant tasks, so their not ideal for frequent access of small tasks, but are great for long running tasks like Image/Audio generation.

Yep Open WebUI's switch to a non OSS license to inhibit competitive forks [1], in their own words [2] ensures I'll never use them. Happy to develop an OSS alternative that does the opposite whose rewrite on extensibility enables community extensions can replace built-in components and extensions so it can easily be rebranded and extended with custom UI + Server features.

The goal is for the core main.py to be a single file without requiring additional dependencies, anything that does can be loaded as an extension (i.e. just a folder with .py server and UI hooks). There's also a script + docs so you can mix n' match the single main.py file and repackage it which whatever extensions you want included [3].

No custom state machine or agent, it's only a copy of Anthropic's 3 computer use tools: run_bash, edit, computer.

It's run in the same process, there's no long agent loops, everything's encapsulated within a single message thread.

Most announcements slip through without notice, it only picks up votes when it hits the main page.

v1 also took a while to make it to HN, v3 is a complete rewrite focused on extensibility with a lot more new features.

Yep, but it only supports GitHub OAuth. i.e. Content is either saved under no user (anonymous) or the authenticated GitHub User.

I wouldn't use Claude API Key pricing, but I also wouldn't get a Claude Max sub unless it was the only AI tool I used.

Antigravity / Google AI Pro is much better value, been using it as my primary IDE assistant for a couple months and have yet to hit a quota limit on my $16/mo sub (annual pricing) which also includes a tonne of other AI perks inc. Nano Banana, TTS, NotebookLM, storage, etc.

No need to use Anthropic's premium models for tool calling when Gemini/MiniMax are better value models that still perform well.

I still have a Claude Pro plan, but I use it much less than Antigravity and thanks to Anthropic axing their sub usage, I no longer use it outside of CC.

Rate limits mostly - plus claude code is a relatively recent thing but sonnet api has been around for a while with 3rd party apps (like cline). In those scenarios, it was only api.

Couldn't think of a better title, do you have any suggestions?
