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
