FOR APP BUILDERSFree and open source

Add BYOK and MCP support to your app.

A library for text, image, video and local AI models. Install it yourself or with a coding agent.

Paste into your agent

My app, my keys

Add AI provider support to this project with AI Connections (npm package: ai-connections). First read https://seeker-studio.games/ai-connections/llms.txt and follow it.

BYOK for your users

Integrate BYOK support into this app with AI Connections (npm: ai-connections), so each user brings their own AI provider key. Read https://seeker-studio.games/ai-connections/llms.txt first, use full mode, and hook it into this app's sign-in.

Run once in your project

npx ai-connections-cli skill

Teaches Claude Code and Codex to use it in every session.

Your agent reads llms.txt and does the rest.

What's this for?

AI Connections connects your app to AI providers and makes its features available to agents.

BYOK

Bring your own key

You or your users connect an AI provider with an API key and pay that provider directly.

Shared adapters handle authentication, model names, request formats and errors, so you can add or switch providers through a common interface.

MCP

Model Context Protocol

MCP gives agents a standard way to call your app's actions, such as submitting an image job or reading its output.

Your agent tools reuse the services and permissions behind your app's interface.
