<strong>Give your AI agent superpowers. One line. 2,000+ AI models and APIs — data APIs are free.</strong>
English | 中文 | 日本語 | 한국어 | Español | Français | Deutsch | Português
Your AI coding assistant is smart, but it's trapped in a box. It can't search the web, check social media, generate images, or access real-time data — unless you wire up each API yourself.
SandBase changes that. One command connects your agent to 2,000+ AI models and APIs through the Model Context Protocol. No API keys to manage. No configuration headaches.
Building directly over HTTP instead of MCP? Start with the SandBase API quickstart or compare the unified LLM, image, and video API with specialized model gateways.
Setup
Paste this into your agent and let it do the rest:
set up https://www.sandbase.ai/SKILL.md
It reads the SandBase Skill, runs connect itself, and asks you to approve one browser sign-in. Prefer to drive it yourself:
npx -y @sandbaseai/cli@latest connect
Or install the official Homebrew formula on macOS or Linux:
brew install sandbaseai/tap/sandbaseai-cli
sandbase connect
See the Homebrew launch announcement and macOS/Linux CI evidence.
Approve the browser authorization once; each supported client can then discover,
inspect, and run available SandBase models and APIs through the local MCP bridge.
Start a new session afterwards so the sandbase_* tools load.
Every GitHub release publishes its own SHA-256 next to the tarball, so you can pin
and verify an exact build instead of tracking latest:
V=$(npm view @sandbaseai/cli version)
curl -fL -O "https://github.com/sandbaseai/cli/releases/download/v$V/sandbaseai-cli-$V.tgz"
shasum -a 256 "sandbaseai-cli-$V.tgz" # compare against the checksum on the release page
npx -y "./sandbaseai-cli-$V.tgz" connect
Want to inspect compatibility before signing in or changing configuration? The client catalog is a read-only command — it writes nothing and needs no account:
npx -y @sandbaseai/cli@latest catalog --json
A no-write catalog audit and a bounded doctor check against an empty isolated profile.
Homebrew users can run the same read-only check with sandbase catalog --json.
What It Costs
| Price | |
|---|---|
| Data APIs — search, social, scraping, e-commerce, finance | Free |
| Discovery, inspection, run status, balance, file upload | Free |
| Models — LLM, image, video, audio | Paid per call or per million tokens |
sandbase inspect <tool> always shows the current price before you run anything;
base_price: 0 means the call is free. Prices can change, so trust the live
response over any example in this file.
