Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 11 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability77
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 1080 tokens (~98/item across 11 items; 11 tools + 0 resources), lean.Pass
- 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 11 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 12 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail
How do I install the io.github.eltociear/skill-audit-mcp server?
io.github.eltociear/skill-audit-mcp is a hosted endpoint at https://eltociear-skill-audit.hf.space/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

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 →

What is the io.github.eltociear/skill-audit-mcp server?
io.github.eltociear/skill-audit-mcp is listed in the public MCP registry as io.github.eltociear/skill-audit-mcp. Scan agent skills and MCP servers for malicious patterns before you load them. This page covers its hosted endpoint (https://eltociear-skill-audit.hf.space/mcp).
Is the io.github.eltociear/skill-audit-mcp server safe to use?
io.github.eltociear/skill-audit-mcp scores 77 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 io.github.eltociear/skill-audit-mcp server expose?
io.github.eltociear/skill-audit-mcp exposes 11 tools: paid_catalogue, air_quality, geocode, earthquakes, public_holidays, and 6 more. Their descriptions and schemas cost roughly 1,019 tokens of context every time the server is loaded.
Does the io.github.eltociear/skill-audit-mcp server require authentication?
No. We connected to io.github.eltociear/skill-audit-mcp without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the io.github.eltociear/skill-audit-mcp server still maintained?
io.github.eltociear/skill-audit-mcp is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
