Sandbase Harness

by sandbaseai · sandbaseai/sandbase-harness

InstallableBundlenpmfresh

Open-source CMA-compatible agent runtime for any model, with MCP tools, sandboxed sessions, audit, replay, and a local console. Includes a native DeepSeek Harness bundle over stdio MCP.

Install Sandbase Harness

Clean install: prebuilt on npm and declares a `dsh.bundle` layer.

The one-line version

dsh plugin --profile my-profile add managed-agents

The easy path: this bundle is published to npm, so the install pulls a prebuilt artifact — no build step runs on your machine and no build approval is needed.

From npm — installs a prebuilt artifact, no build step on your machine

# 1. add the bundle to a profile — --profile my-profile points at $DSH_HOME/profiles/my-profile
dsh plugin --profile my-profile add managed-agents

# 2. verify: the bundle should show up as a layer in the resolved config
dsh --profile my-profile --dump-config

# 3. boot the profile
dsh --profile my-profile

Package: managed-agents

Prefer to install from source instead?

From GitHub — pulls source, and may ask for build approval on first run

# 1. add the bundle to a profile — --profile my-profile points at $DSH_HOME/profiles/my-profile
dsh plugin --profile my-profile add github:sandbaseai/sandbase-harness#<commit-sha>

# 2. verify: the bundle should show up as a layer in the resolved config
dsh --profile my-profile --dump-config

# 3. boot the profile
dsh --profile my-profile
