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 Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- 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 Usability67
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 789 tokens (~197/item across 4 items; 4 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 Management37
- Stability observed for 11 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage93
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 79% of tool parameters carry a description.Partial
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 5 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 SkillAgent MCP server?
SkillAgent is a hosted endpoint at https://skillagent.dev/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 Get an agent skill ~87
Get one skill as Markdown: summary, metadata, install command and the full skill file. `owner` and `name` are the last two segments of a skill's pageUrl (https://skillagent.dev/skill/{owner}/{name}).
| Name | Type | Req | Description |
|---|---|---|---|
| name | string | yes | Skill slug from the pageUrl. |
| owner | string | yes | GitHub owner, e.g. anthropics. |
No output schema declared.
No examples provided.
install_skill Get install instructions for a skill ~163
Exact installation instructions for one skill on one agent: the install command(s) when one exists, otherwise the file to create (path relative to the project root) with its content. This tool does not install anything; apply the result yourself, and only after showing the user the skill and getting their approval. Includes the safety summary. Refuses (isError) when the skill's safety scan is at "warning". `owner` and `name` are the last two segments of a skill's pageUrl.
| Name | Type | Req | Description |
|---|---|---|---|
| agent | string | yes | The agent to install into, e.g. claude-code, cursor, codex. |
| name | string | yes | Skill slug from the pageUrl. |
| owner | string | yes | GitHub owner, e.g. anthropics. |
No output schema declared.
No examples provided.
recommend_skills Recommend agent skills for a project ~227
Recommend skills for a project from a description of it: languages, frameworks or dependencies (e.g. names from package.json or requirements.txt), a task, and the agent the user runs. Returns a ranked shortlist; each entry has the skill record and a `why` explaining the match (matched terms, fit for the agent, freshness, quality, safety). Ranking is deterministic. Skills whose safety scan is at "warning" or whose source is gone are excluded, and the result says how many were.
| Name | Type | Req | Description |
|---|---|---|---|
| agent | string | – | The agent the user runs; skills made for it rank higher. |
| dependencies | array | – | Package names from a manifest, e.g. ["@playwright/test", "prisma"]. |
| frameworks | array | – | Frameworks and tools, e.g. ["next.js", "playwright"]. |
| languages | array | – | Programming languages, e.g. ["typescript", "python"]. |
| limit | integer | – | – |
| task | string | – | What the user wants to do, e.g. "write e2e tests". |
No output schema declared.
No examples provided.
search_skills Search agent skills ~176
Search the SkillAgent catalogue of AI agent skills, rules files and MCP servers. Returns matching skills with description, format, stars, quality score, freshness, page URL and install command.
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | – | Category, e.g. development, data-analytics, security. |
| format | string | – | Skill format, e.g. skill-md, claude-md, agents-md, cursorrules, mcp-server. |
| health | string | – | Filter by repository freshness or reachability. |
| limit | integer | – | – |
| offset | integer | – | – |
| platform | string | – | Agent platform, e.g. claude-code, cursor, codex, vscode-copilot, windsurf. |
| query | string | – | Keywords matched against name, description, owner and tags. |
| sort | string | – | – |
No output schema declared.
