SandBase

@sandbaseai/cli

Give your AI agent superpowers. One line. 2,000+ AI models and APIs. 100 free data API calls a day, then pay per call from one balance.

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

sandbase inspect always shows the current price before you run anything; data APIs covered by the daily allowance also show pricing.free_quota. The 100 free calls are shared across eligible data APIs and reset at 00:00 UTC; after that, calls are billed per call. sandbase balance --json shows today's remaining free calls as free_api_quota. Prices can change, so trust the live response over any example in this file.

Visit the official SandBase CLI project page for a compact overview. For a security-focused walkthrough of client detection, MCP tools, and rollback, read the 25-client SandBase CLI setup guide. AI agents and automated installers can use the concise llms-install.md instructions.

SandBase Open-Source Stack

• [SandBase Harness](https://github.com/sandbaseai/sandbase-harness) — self-hosted agent runtime with persistent sessions, sandbox isolation, approvals, audit, and replay.
• [SandBase Agent Skills](https://github.com/sandbaseai/sandbase-skills) — 88 installable Skills for research, social intelligence, marketing, and business workflows.
• [SandBase for Codex](https://github.com/sandbaseai/sandbase-codex-plugin) — official Codex plugin packaging the SandBase MCP bridge and guided Agent Skill; its required HOL security scan passes on main.

Discover the authenticated remote bridge in the official MCP Registry, read its Registry community showcase, or find it through Chinese Independent Developer, Awesome MCP, Glama, TensorBlock MCP Index, MCPRepository, VaultPlane, AIMCP, MCP Server Hub, MCP Server Spot, or the Awesome AI API Proxy. External maintainers have merged SandBase into Awesome Codex CLI, Awesome Agent Skills, and Awesome MCP Server. The Hermes integration is independently listed in the Hermes Atlas ecosystem catalog and as beta in Awesome Hermes Agent. Install its verified sandbase Agent Skill from skills.sh, the sandbaseai/cli/sandbase listing on SkillsCat, the sandbaseai/cli/sandbase listing on skills.re, the 93/100 verified SandBase listing on vSkill, the security-audited SandBase listing on Skillstore, or the versioned sandbaseai/sandbase snapshot on Agent Skill Hub.

A Verifiable Agent Workflow

After connecting, ask your agent to follow the same inspectable sequence for search, data APIs, language models, image generation, video generation, and other catalog capabilities:

1. Use sandbase_discover to find candidates by task or capability.
2. Use sandbase_inspect to read the current input schema, pricing, and execution requirements.
3. Confirm the selected endpoint and parameters before calling sandbase_run. Data APIs include 100 free calls per organization per UTC day, then are billed per call like models; confirm the cost shown by sandbase_inspect before paid runs.
4. For asynchronous work, use sandbase_run_get with the returned run_id instead of creating a duplicate run.
5. Use sandbase_runs to review recent run status and recorded cost.
6. Use sandbase_account to check the current account balance.

For example, start with a non-billable discovery request:

Find image models suitable for a square product illustration. Compare the

required inputs and current pricing for the best two candidates. Do not run

either model yet.

Discovery and inspection never cost anything, so an agent can always survey the catalog before it spends.

After reviewing the live response, explicitly approve the endpoint and inputs you want to run. Catalog entries, schemas, pricing, latency, and availability can change, so use the tool response from the current session rather than a static example.
