SandBase

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.

npx -y https://github.com/sandbaseai/cli/releases/download/v0.1.17/sandbaseai-cli-0.1.17.tgz 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.

For a reproducible install, verify the immutable release archive before running it. The SHA-256 for sandbaseai-cli-0.1.17.tgz is 1ad535b2899ca460b57b3c268aef278fee28fd28e649a89b92951514fd71fffa.

curl -fL -o sandbaseai-cli-0.1.17.tgz \
  https://github.com/sandbaseai/cli/releases/download/v0.1.17/sandbaseai-cli-0.1.17.tgz
echo '1ad535b2899ca460b57b3c268aef278fee28fd28e649a89b92951514fd71fffa  sandbaseai-cli-0.1.17.tgz' | shasum -a 256 -c -
npx -y ./sandbaseai-cli-0.1.17.tgz connect

Approve the browser authorization once; each supported client can then discover, inspect, and run available SandBase models and APIs through the local MCP bridge.

Want to inspect compatibility before signing in or changing configuration? The current v0.1.17 GitHub release includes a verified 25-client catalog:

npx -y https://github.com/sandbaseai/cli/releases/download/v0.1.17/sandbaseai-cli-0.1.17.tgz catalog --json

Homebrew users can run the same read-only check with sandbase catalog --json.

The npm latest tag currently serves v0.1.14 while tokenless trusted publishing is being enabled. The GitHub release tarball is built from the immutable v0.1.17 tag; its SHA-256 is published with the release.

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 — 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.

• SandBase for Codex — 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, parameters, and possible cost before calling sandbase_run.

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.

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.

See the complete Claude Code and Codex walkthrough or the Chinese workflow guide. For a live catalog example, read the GitHub connector discover-and-inspect dogfooding note.

What's Inside

Supported Clients (25 Targets)

Works with every major AI coding tool:

Preview the complete compatibility catalog without signing in or changing any files:

npx -y https://github.com/sandbaseai/cli/releases/download/v0.1.17/sandbaseai-cli-0.1.17.tgz catalog --json

# Connect all detected clients at once
npx -y https://github.com/sandbaseai/cli/releases/download/v0.1.17/sandbaseai-cli-0.1.17.tgz connect

# Or target one specific client
npx -y https://github.com/sandbaseai/cli/releases/download/v0.1.17/sandbaseai-cli-0.1.17.tgz connect --client cursor

OpenClaw quickstart

Target OpenClaw directly, then ask the CLI to read back the managed MCP server and SandBase Skill before you rely on them:

npx -y https://github.com/sandbaseai/cli/releases/download/v0.1.17/sandbaseai-cli-0.1.17.tgz connect --client openclaw
npx -y https://github.com/sandbaseai/cli/releases/download/v0.1.17/sandbaseai-cli-0.1.17.tgz doctor --client openclaw

After doctor reports the credential, MCP bridge, and Skill as configured, restart OpenClaw and make a natural-language request that needs SandBase. If OpenClaw already has a non-SandBase MCP server named sandbase, the installer leaves it untouched instead of overwriting it. To remove the managed MCP entry and local credential later:

npx -y https://github.com/sandbaseai/cli/releases/download/v0.1.17/sandbaseai-cli-0.1.17.tgz unregister --client openclaw

OpenClaw currently exposes no supported Skill removal command, so unregister reports that limitation and leaves the verified SandBase Skill installed.

Hermes quickstart

SandBase can install both its managed Hermes Skill and local MCP entry in one authorization transaction:

npx -y https://github.com/sandbaseai/cli/releases/download/v0.1.17/sandbaseai-cli-0.1.17.tgz connect --client hermes
npx -y https://github.com/sandbaseai/cli/releases/download/v0.1.17/sandbaseai-cli-0.1.17.tgz doctor --client hermes

doctor verifies the owned local credential, MCP entry, and Skill. Restart Hermes to confirm native discovery in a fresh client session, then use the SandBase Skill or MCP tools. A pre-existing, non-SandBase MCP entry named sandbase is left untouched. To remove only the managed Hermes configuration, Skill, and local credential while retaining the shared bridge for other clients:

npx -y https://github.com/sandbaseai/cli/releases/download/v0.1.17/sandbaseai-cli-0.1.17.tgz unregister --client hermes

The integration is independently listed by Hermes Atlas and Awesome Hermes Agent.

1. Run connect → CLI opens browser auth → you approve

2. API key saved locally (file permissions 0600)

3. MCP bridge configured for your client

4. 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)

Recommended workflow:

discover → inspect → run

1. sandbase_discover(q: "twitter search")          → find current candidates
2. sandbase_inspect(name: discovered_name)          → get schema and pricing
3. sandbase_run(name: discovered_name, input: {...}) → run after confirmation

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 https://github.com/sandbaseai/cli/releases/download/v0.1.17/sandbaseai-cli-0.1.17.tgz connect

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