These independent directory pages are discovery mirrors; this repository and its
release metadata remain the source of truth.

## Capabilities

- Persistent agent sessions, event streams, artifacts, memory, and resumable work
- Local, Docker, Kubernetes, and self-hosted worker sandbox providers
- MCP toolsets and a six-tool stdio MCP bridge
- Managed credentials, permission policies, approvals, audit logs, and replay
- Built-in local Console and `/v1` HTTP API
- OpenAI, Anthropic, MiniMax, and OpenAI-compatible model providers, including DeepSeek V4
- SQLite and file-backed local-first storage with no required hosted control plane

## MCP bridge

- Docker image: `ghcr.io/sandbaseai/sandbase-harness-mcp:0.3.8`
- Tools: `list_agents`, `create_session`, `run_session`, `get_session`, `list_artifacts`, `stop_session`
- Runtime endpoint: `MANAGED_AGENTS_URL` (default `http://127.0.0.1:3000`)
- Optional authentication: `MANAGED_AGENTS_API_KEY`

## Limits and safety

- The MCP image is a bridge to a running Harness API; it is not a standalone model provider.
- The local sandbox shares the host OS user boundary; use Docker or Kubernetes for stronger isolation.
- Configure model-provider credentials through the runtime's environment or secret-management path; do not commit keys.
