Category Security
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 Security100
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- Runs setuptools.build_meta at install time, a recognised build step with no custom scripting around it. View diagnostics → Pass
- No production dependencies, so there is no dependency health to assess. View diagnostics → Pass
Provenance & Transparency100
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to pezhik/skilltotal). View diagnostics → Pass
- Clear OSI-approved license (Apache-2.0).Pass
- Actively maintained (last published 0 days ago).Pass
- Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability61
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1211 tokens (~403/item across 3 items; 3 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 Management100
- No destabilizing schema changes in the last 30 days.Pass
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
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 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 →
diff_components Compare two versions of a component ~455
Compare two versions of a component and report what changed. Use for upgrade reviews (is the new version riskier than the one already vetted?). Both sides accept the same sources as scan_component. The default summary gives each side's verdict, the verdict change, the risk-score delta, new and removed risk findings (in scan_component's why shape) and capability changes; detail="full" returns the complete diff with every new/resolved/changed finding. Decide on the verdict (level, headline, has_malicious_indicators), not on the number of findings: a finding whose threat_class is "capability" is something the component can do (run commands, read files, reach the network) and adds no risk; malicious_indicator and risky_construct findings are what the verdict and score rest on. Not checked: the code of the component's dependencies, known vulnerabilities (CVEs), and runtime behaviour.
| Name | Type | Req | Description |

list_rules List detection rules ~187
List SkillTotal detection rules: id, severity, category, title, threat class and capability. Use it to look up a rule id from a scan_component or diff_components result, or to see what SkillTotal checks before scanning. It reads the rule list bundled with this engine: offline, instant, no side effects. With no arguments it returns every rule. ids and query narrow the list and combine (a rule must match both); no match returns an empty array []. Pass verbose=true for each rule's description and recommendation.
| Name | Type | Req | Description |
|---|---|---|---|
| ids | array | – | Only these rule ids, as a finding's rule field shows them (case-insensitive). Unknown ids are skipped, not an error. |
| query | string | – | Only rules whose id or title contains this text (case-insensitive substring; descriptions are not searched). |
| verbose | boolean | – | Also return each rule's description and recommendation. |
No output schema declared.

scan_component Scan a component ~493
Statically scan an AI component (agent skill, MCP server, npm/PyPI package, repository, local path or archive) for supply-chain risks, dangerous capabilities, prompt-injection surfaces, and exfiltration paths. Use this BEFORE installing or trusting a component. The scan is local, deterministic, and never executes the component's code. A local path is read in place; a git URL or npm:/pypi:/vscode:/openvsx: source is downloaded to a temp folder that is removed afterwards. A source over the size limit is refused with an error naming the setting that raises it. Decide on the verdict (level, headline, has_malicious_indicators), not on the number of findings: a finding whose threat_class is "capability" is something the component can do (run commands, read files, reach the network) and adds no risk; malicious_indicator and risky_construct findings are what the verdict and score rest on. Not checked: the code of the component's dependencies, known vulnerabilities (CVEs), and runtime behaviour. The default summary is a JSON object: component, verdict {level, headline, has_malicious_indicators}, decision (one line), risk_score, risk_level, why [{rule, threat_class, severity, title, evidence ["file:line snippet"]}] (risk findings first), capabilities [names], counts {findings_by_threat_class, needs_review}, check_manually [notes to read], not_checked [what this scan does not cover], engine {version, ruleset}. Pass detail="full" for the complete report.

What is the SkillTotal MCP server?
SkillTotal is an MCP server listed in the public MCP registry as ai.skilltotal/skilltotal. Deterministic security scan of MCP servers, agent skills and npm/PyPI packages. Runs locally. This page covers its PyPI package (skilltotal).
Is the SkillTotal MCP server safe to use?
SkillTotal scores 93 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 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 SkillTotal MCP server expose?
SkillTotal exposes 3 tools: scan_component, diff_components, list_rules. Their descriptions and schemas cost roughly 1,135 tokens of context every time the server is loaded.
Is the SkillTotal MCP server still maintained?
SkillTotal is still listed as active in the MCP registry. We last reached this channel on 5 November 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 SkillTotal MCP server under?
SkillTotal 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.
