Trust breakdown (7 categories)
How this component scores in each security and reliability category. 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. How we score → Why this is hard to score →
Supply Chain Security50
- Malware scan not yet available for this package.Unverified
- No known CVEs affecting this package version or its production dependencies.Pass
- Runs hatchling.build at install time, a recognised build step with no custom scripting around it. View diagnostics → Pass
- 1 of 17 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency100
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to SCGIS-Wales/helm-mcp). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 13 days ago).Pass
- Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability51
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 15167 tokens (~329/item across 46 items; 46 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management93
- Stability check failed: the tool surface changed between 0.4.2 and 0.5.0: 0 tool removals, 3 breaking changes, 0 additions. See how to fix → Fail
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (24% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- All 3 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.Pass
- An AI judge read all 47 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Common questions
What is the io.github.SCGIS-Wales/helm-mcp server?
io.github.SCGIS-Wales/helm-mcp is listed in the public MCP registry as io.github.SCGIS-Wales/helm-mcp. The full Helm CLI surface as 46 MCP tools, backed by the Helm v3 and v4 Go SDKs. This page covers its PyPI package (helm-mcp).
Is the io.github.SCGIS-Wales/helm-mcp server safe to use?
io.github.SCGIS-Wales/helm-mcp scores 75 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 24 October 2026. Its build provenance is signed and verified. 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 io.github.SCGIS-Wales/helm-mcp server expose?
io.github.SCGIS-Wales/helm-mcp exposes 46 tools: helm_create, helm_dependency_build, helm_dependency_list, helm_dependency_update, helm_env, and 41 more. Their descriptions and schemas cost roughly 14,933 tokens of context every time the server is loaded.
Is the io.github.SCGIS-Wales/helm-mcp server still maintained?
io.github.SCGIS-Wales/helm-mcp is still listed as active in the MCP registry. We last reached this channel on 24 October 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 io.github.SCGIS-Wales/helm-mcp server under?
io.github.SCGIS-Wales/helm-mcp declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
