SandBase

Open-source CLI and local MCP bridge that connects AI agents to 2,000+ AI models through one account.

Documentation

@sandbaseai/cli

Give your AI agent superpowers. One command. 2,000+ AI models.

SandBase CLI connects AI clients to 2,000+ AI models

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 through the Model Context Protocol. No API keys to manage. No configuration headaches.

npx -y @sandbaseai/cli connect

That's it. Your agent now has access to everything.

SandBase Open-Source Stack

SandBase Harness — self-hosted agent runtime with persistent sessions, sandbox isolation, approvals, audit, and replay.
SandBase Agent Skills — 88 installable Skills for research, social intelligence, marketing, and business workflows.

After connecting, just ask your agent naturally. It handles the rest.

Agent calls tools on-demand. No daemon. No background process.

Commands

CLI Commands

sandbase connect [--client <name>]    # Authorize + configure
sandbase doctor [--client <name>]     # Health check
sandbase unregister [--client <name>] # Remove configuration
sandbase catalog --json               # List all supported clients

MCP Tools (available to your agent after connecting)

Tool	Purpose
`sandbase_discover`	Search all 2,000+ available AI models
`sandbase_inspect`	Get input schema, pricing, and ready-to-use template
`sandbase_run`	Execute a model or API endpoint
`sandbase_run_get`	Poll status/result of an async run (video gen, etc.)
`sandbase_runs`	List your recent API calls with cost breakdown
`sandbase_account`	Check account balance (free, no cost)

Workflow your agent follows automatically:

discover → inspect → run

1. sandbase_discover(q: "twitter search")        → finds matching tools
2. sandbase_inspect(name: "twitter_timeline")    → gets schema + pricing
3. sandbase_run(name: "twitter_timeline", ...)   → executes and returns data

Security

Zero secrets in URLs or CLI args — OAuth device flow with PKCE
Restricted file permissions — Credentials stored with 0600
Ownership-aware updates — Existing JSONC comments and user-managed MCP entries are preserved
Exact rollback — On failure or unregister, only configuration owned by SandBase is removed
Revoke anytime — One click in the SandBase Dashboard

Get Started

npx -y @sandbaseai/cli connect

Then ask your agent to do something it couldn't before.
