Submit to the Marketplace

Share your Claude Code skills, MCP servers, or CLAUDE.md templates with the community.

What we accept

The Prefex Marketplace is a curated catalog of tools that help Claude Code users save money and be more productive. We accept three types of entries:

  1. Skills, SKILL.md files that teach Claude Code domain-specific patterns, workflows, or coding standards
  2. MCP Servers, Model Context Protocol servers that extend Claude Code's capabilities (search, databases, APIs, etc.)
  3. CLAUDE.md Templates, Project configuration templates that give Claude Code the right context for specific tech stacks

Every entry must be open source (MIT, Apache-2.0, BSD, or ISC license) and hosted on a public GitHub repository.

Two tiers

Entries are classified into two quality tiers. Both are free and visible to all users.

Verified

Manually reviewed against our scoring rubric. Must average 2.0/3.0 or higher.

  • Green checkmark badge in the marketplace
  • Sorted first in search results
  • Highlighted in "For You" recommendations
  • Featured on the public marketplace page

Community

Passes automated checks only. No manual review required.

  • Blue badge in the marketplace
  • Visible to all users
  • Can be promoted to Verified based on community feedback
  • Auto-removed if thumbs-down ratio exceeds 60% after 50+ installs

Automated checks (required for all entries)

Every submission is run through automated validation. All checks must pass before an entry is listed.

Must pass

  • Frontmatter has required fields: name, description, version, author, license
  • SKILL.md is under 50KB, no binaries or minified code
  • No hardcoded credentials, no curl | bash patterns, no dangerouslyDisableSandbox
  • License is MIT, Apache-2.0, BSD-2-Clause, BSD-3-Clause, or ISC
  • No duplicate or near-duplicate name in the existing catalog
  • Description is over 20 characters
  • Has a "When to Activate" or "When to Use" section
  • At least one code example or actionable instruction
  • MCP-specific: valid JSON config with command or url, env vars documented
  • Template-specific: at least 3 sections, under 500 lines, no hardcoded project paths

Automatic rejection

  • Outbound network calls in skill body (skills should not phone home)
  • Obfuscated or minified code
  • Entries that duplicate functionality of an existing Verified entry
  • Marketing content disguised as a skill (no value to the user)
  • Entries that require a paid service without clearly stating it

Scoring rubric (Verified tier)

Each criterion is scored 0-3. Entries must average 2.0 or higher to earn Verified status. Scores are published transparently in the catalog.

Criterion0, Reject1, Weak2, Good3, Excellent
Value clarity No clear benefit Vague claim Specific benefit with rationale Quantified impact (e.g., "30% fewer retries")
Scope fit Duplicates existing Significant overlap Fills a gap Addresses an unmet need
Quality Broken or misleading Works, rough edges Well-structured Reference implementation
Audience Author-only use Niche One persona ($20/$100/API) Broad audience
Maintenance Abandoned Responsive author Versioned, active Changelog, tests, active
