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 4 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 Usability70
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 313 tokens (~78/item across 4 items; 4 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 Coverage67
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 4 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
How do I install the AISkills402 MCP server?
AISkills402 is a hosted endpoint at https://mcp.aiskills402.com/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 →
get_skill ~67
Get one skill card (free) plus the exact x402 payment_required body for its one-time purchase of the SKILL.md file, and how_to_buy. Price is price_usd on the card. Buying is over HTTP; MCP does not take payments.
| Name | Type | Req | Description |
|---|---|---|---|
| slug | string | yes | – |
No output schema declared.
No examples provided.
list_categories ~41
List the twelve skill categories (free) with a short introduction and how many skills are listed in each. Use a slug as the category filter of search_skills.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
redownload_skill ~46
Re-download the SKILL.md file you already bought (free), using the token from your purchase receipt. Always returns the current version of the skill.
| Name | Type | Req | Description |
|---|---|---|---|
| token | string | yes | – |
No output schema declared.
No examples provided.
search_skills ~159
Search the tested agent skill files for sale (free). Give a plain-language query (for example: sound less like ChatGPT), or filter by category, tag or language, or combine them. With a query the results come ranked by relevance; without one you get the featured skills first. Each card has match_reason (the field that matched, or the filter), price_usd (a one-time purchase of the SKILL.md file, yours forever), what it is for, what it is not for, and how it was tested. limit is at most 24.
