Plugin Overview & Capabilities

AI-assisted organization based on the public repository snapshot. The content must be grounded in source evidence and does not replace compatibility or security verification.

source-grounded
SandBase Harness is a local-first, self-hosted agent runtime and MCP bridge compatible with DeepSeek Harness through Cordis configuration. It provides isolated session execution environments (local process, Docker, Kubernetes, or worker queues), persistent session replay, credential vaults, and an integrated local management console.

Key Capabilities

  • Multi-backend sandboxed execution across local processes, Docker containers, and Kubernetes clusters
  • Model Context Protocol (MCP) bridge and stdio tool integration for DeepSeek Harness
  • Persistent agent sessions backed by local SQLite metadata and state storage
  • Resumable Server-Sent Events (SSE) stream for event logging, audit trails, and session replay
  • Credential vaults and permission policies with interactive or automated approval gates
  • Integrated local developer console for inspecting agent sessions and configuration

Useful For

  • Executing untrusted or model-generated code securely inside isolated Docker or Kubernetes containers
  • Bridging external MCP servers and tools into DeepSeek Harness workflows with strict permission policies
  • Debugging and replaying long-running autonomous agent interactions locally

Who It Fits

  • AI agent engineers requiring secure sandboxed execution for generated scripts
  • DeepSeek Harness users needing credential governance and granular MCP tool approval
  • Developers building local-first, self-hosted agent infrastructure without hosted control planes

Documented Limitations

  • Requires Node.js 22 or higher
  • Containerized or cluster sandboxing backends require operational Docker or Kubernetes environments
  • Multi-agent coordinator threads and hosted MCP tunnel features are currently unsupported
