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 2026-09-21. - **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**: 45/100 - 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 20 days ago). - Disclosure check failed: no security disclosure policy was found in the source repository. - **Schema Quality & AI Usability**: 84/100 - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name). - AI-judged instruction clarity (good). - Tool/resource definitions use about 938 tokens (~85/item across 11 items; 11 tools + 0 resources), lean. - Usage-examples check failed: none of the tools include examples. - **Stability & Change Management**: 70/100 - Stability observed for 21 of 30 days with no destabilising changes; credit accrues until the full window elapses. - **Tool Coverage**: 98/100 - 100% of tools have a non-trivial description (not blank, and not just the tool's name). - 95% of tool parameters carry a description. - **Tool Safety**: 75/100 - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured. - 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "queryDruidSql" implies "execute" and declares readOnlyHint instead, contradicting what its own name says it does. - An AI judge read all 11 captured unit(s) of tool text and found none that tries to manipulate the model reading it. - **Capabilities**: 100/100 - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28. **Unverified: 1 category.** A category scored 0 because we could not verify it: 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 com.iunera/druid-mcp-server server? com.iunera/druid-mcp-server runs locally as a container image, launched with docker run --rm -i docker.io/iunera/druid-mcp-server:2.0.1.

AI-powered MCP server for Apache Druid cluster management and analytic. This page covers its container image (docker.io/iunera/druid-mcp-server:2.0.1). ### Is the com.iunera/druid-mcp-server server safe to use? com.iunera/druid-mcp-server scores 50 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 com.iunera/druid-mcp-server server expose? com.iunera/druid-mcp-server exposes 11 tools: getCompactionConfig, getCompactionStatus, getDatasources, getLookups, queryDruidSql, and 6 more. Their descriptions and schemas cost roughly 938 tokens of context every time the server is loaded. ### Is the com.iunera/druid-mcp-server server still maintained? com.iunera/druid-mcp-server is still listed as active in the MCP registry. We last reached this channel on 21 September 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 com.iunera/druid-mcp-server server under? com.iunera/druid-mcp-server 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/iunera/druid-mcp-server - Changelog RSS feed: https://verifymcp.io/servers/com-iunera-druid-mcp-server/docker-io-iunera-druid-mcp-server-2-0-1.xml - Changelog JSON feed: https://verifymcp.io/servers/com-iunera-druid-mcp-server/docker-io-iunera-druid-mcp-server-2-0-1.json - HTML version of this page: https://verifymcp.io/servers/com-iunera-druid-mcp-server/docker-io-iunera-druid-mcp-server-2-0-1
