Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog) Scored 2026-08-23. - **Supply Chain Security**: 0/100 - Malware scan not yet available for this package. - Known CVEs could not be checked: this artifact ships no SBOM, so there is no dependency list to read. Publishing one would let us assess it. - Install-script risk not yet assessed. - Dependency health could not be checked: this artifact ships no SBOM, so there is no dependency list to read. Publishing one would let us assess it. - **Provenance & Transparency**: 48/100 - Source repository is publicly reachable at the declared URL. - Provenance check failed: no build-provenance attestation is published. - Clear OSI-approved license (Apache-2.0). - Actively maintained (last published 3 days ago). - Publishes a security disclosure policy (SECURITY.md). - **Schema Quality & AI Usability**: 69/100 - AI-judged instruction clarity (good). - Tool/resource definitions use about 207 tokens (~34/item across 6 items; 6 tools + 0 resources), lean. - Usage-examples check failed: none of the tools include examples. - **Stability & Change Management**: 0/100 - Stability not yet verified: not enough scan history yet (needs a 30-day window). - **Tool Coverage**: 100/100 - 100% of tools have a non-trivial description (not blank, and not just the tool's name). - 100% of tool parameters carry a description. - **Capabilities**: 100/100 - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28. **Unverified: 2 categories.** Categories scored 0 because we could not verify them: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm. ## Install ### How do I install the SandBase Harness MCP server?

SandBase Harness is an MCP server listed in the public MCP registry as io.github.sandbaseai/sandbase-harness. Stdio MCP bridge for SandBase Harness agents, sessions, turns, artifacts, and cancellation. This page covers its container image (ghcr.io/sandbaseai/sandbase-harness-mcp:0.3.4). ### Is the SandBase Harness MCP server safe to use? SandBase Harness scores 38 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm. ### What tools does the SandBase Harness MCP server expose? SandBase Harness exposes 6 tools: list_agents, create_session, run_session, get_session, list_artifacts, stop_session. Their descriptions and schemas cost roughly 207 tokens of context every time the server is loaded. ### Is the SandBase Harness MCP server still maintained? SandBase Harness is still listed as active in the MCP registry. We last reached this channel on 23 August 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced. ### What licence is the SandBase Harness MCP server under? SandBase Harness declares the Apache-2.0 licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls. ## Links - Repository: https://github.com/sandbaseai/sandbase-harness - Changelog RSS feed: https://verifymcp.io/servers/sandbaseai-sandbase-harness/ghcr-io-sandbaseai-sandbase-harness-mcp-0-3-4.xml - Changelog JSON feed: https://verifymcp.io/servers/sandbaseai-sandbase-harness/ghcr-io-sandbaseai-sandbase-harness-mcp-0-3-4.json - HTML version of this page: https://verifymcp.io/servers/sandbaseai-sandbase-harness/ghcr-io-sandbaseai-sandbase-harness-mcp-0-3-4
