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 5 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 Usability86
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 1917 tokens (~26/item across 72 items; 5 tools + 67 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
- Structured output schemas are declared (80% 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
- We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 7 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
How do I install the io.github.mjaskolski/wondel-skills-mcp server?
io.github.mjaskolski/wondel-skills-mcp is a hosted endpoint at https://skills.wondel.ai/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_journey Get a guided journey ~131
One guided journey as a phase plan: the ordered skills, the decision question each phase answers, the docs/ file it writes, and which phases are go/no-go gates. Pass slug for a known journey, or goal to have one picked.
| Name | Type | Req | Description |
|---|---|---|---|
| context | string | yes | Why are you calling this tool? One line on the user's actual task, in their words — not a restatement of the tool name. |
| goal | string | – | What you are trying to achieve, if you do not know which journey fits |
| slug | string | – | Journey slug, e.g. "grow-website" |
| Name | Type | Req | Description |
|---|---|---|---|
| artifacts | array | yes | – |
| canonical | string | yes | – |
| definition | string | yes | – |

| phases | array | yes | – |
| slug | string | yes | – |
| tagline | string | yes | – |
| useWhen | array | yes | – |
No examples provided.
get_skill Get skill metadata ~168
Metadata for one skill or journey: its definition, when to use it, when not to, and related slugs. Deliberately cheap (~300 tokens) so you can check a candidate before committing context to it. Pass sections to widen, or sections:["all"] for the whole page. This does not return the skill instructions — load_skill does.
| Name | Type | Req | Description |
|---|---|---|---|
| context | string | yes | Why are you calling this tool? One line on the user's actual task, in their words — not a restatement of the tool name. |
| sections | array | – | Which parts to return. Default: definition, use_when, not_for, related. "all" returns the full page. |
| slug | string | yes | Skill or journey slug, e.g. "refactoring-ui" or "create-business" |

| useWhen | array | – | – |
No examples provided.
load_skill Load skill instructions ~133
The skill's actual instructions — the upstream SKILL.md, ready to follow in this session with nothing installed. The response also lists the skill's reference files with their token cost, so you can pull deeper material on demand by calling again with part set to a filename.
| Name | Type | Req | Description |
|---|---|---|---|
| context | string | yes | Why are you calling this tool? One line on the user's actual task, in their words — not a restatement of the tool name. |
| part | string | – | "core" (default) for SKILL.md, or a reference filename from a previous response |
| slug | string | yes | Skill or journey slug |
No output schema declared.
No examples provided.
recommend_skills Recommend skills for a task ~188
Route a task to the right skills. Describe the job in your own words and this returns which skills to load first, which to skip whenever a skill's own "not for" line rules it out for this task — quoted verbatim — and a guided journey when the task spans a whole project rather than one step. This is the tool to reach for first.
| Name | Type | Req | Description |
|---|---|---|---|
| context | string | yes | Why are you calling this tool? One line on the user's actual task, in their words — not a restatement of the tool name. |
| max | integer | – | How many skills to return (default 3) |
| phase | string | – | Where in the work you are |
| stack | string | – | Language, framework or platform, if it narrows the answer |
| task | string | yes | The job to be done, in your own words — a full sentence beats a keyword |
| Name | Type | Req | Description |
|---|---|---|---|
| avoid | array | yes | – |
| journey | object | – | – |
| loadFirst | array | yes | – |
| next | string | yes | – |
| task | string | yes | – |
| then | array | yes | – |
No examples provided.
search_skills Search skills ~172
Search 51 book-based agent skills and 14 guided journeys by keyword or phrase. Each skill is matched against its own trigger text, so plain task language works ("my UI looks amateur", "pricing", "dark mode"). Returns compact hits, each quoting the line that matched. Use recommend_skills instead when you have a task rather than a keyword.
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | – | Restrict to one domain |
| context | string | yes | Why are you calling this tool? One line on the user's actual task, in their words — not a restatement of the tool name. |
| kind | string | – | Restrict to single skills or guided journeys |
| limit | integer | – | Maximum hits (default 8) |
| query | string | yes | Keyword, phrase, slug or plain description of the problem |
| Name | Type | Req | Description |
|---|---|---|---|
| next | string | yes | – |
| query | string | yes | – |
| results | array | yes | – |
