Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account lazymac2x for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Remote MCP server that validates Claude SKILL.md files, scoring them 0–100 and flagging frontmatter, quality and security issues.

What you can do: Validate a whole SKILL.md file, returning a score, a pass/review/fail gate and structured errors and warnings
Lint only the YAML frontmatter and get parsed fields plus rule violations during iterative authoring
Scan a skill for dangerous shell commands, hardcoded secrets and prompt-injection phrases, with excerpts
Run a minimal full validation that returns just the score and ship gate for CI/CD pipelines
When to use it: Useful when authoring or reviewing Claude Skills and you want a quick quality and security check before shipping, or when wiring skill validation into a CI/CD pipeline.
Requirements: A remote MCP endpoint at api.lazy-mac.com; no package, environment variables or headers are declared. Network access to that host is required.

Before you install

Skill content submitted for validation is sent to a third-party hosted service; avoid including real secrets or sensitive material in files you validate. No authentication is declared.

Installation

In SourceWeft

Open Claude Skill Validator in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.lazymac2x%2Fclaude-skill-validator/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Score

90% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
