MCPServers.org vs SkillzBench: Which Agent Skills Platform Should You Trust?
MCPServers.org is a large, free directory of MCP servers, listing 16,671 servers across categories like Development, Productivity, Database, and Web Scraping, with one-click access to official remote servers from Notion, Linear, Stripe, and GitHub. SkillzBench is also free, but it works a level up: it catalogs and verifies AI agent skills (SKILL.md packages), benchmarks each one in a sandbox to publish a measurable Lift, and ships a free MCP connector with per-agent loadouts. If you need to find an MCP server for a specific tool, MCPServers.org's scale wins; if you need to know whether a skill is safe and actually improves your agent, SkillzBench's verification and benchmarking are the difference.
TL;DR
- MCPServers.org lists 16,671 MCP servers across 14 categories including Development, Productivity, Database, Search, and Web Scraping.
- It offers one-click access to official remote MCP servers from Notion, Linear, Stripe, GitHub, Slack, HubSpot, Canva, and Figma with no local install.
- SkillzBench is a free directory of AI agent skills (SKILL.md packages) for Claude Code, Codex, Cursor, Gemini CLI, and chat-app agents.
- Published research found roughly 26% of agent skills carry at least one vulnerability, which is the problem SkillzBench's verification layer targets.
- SkillzBench pins every skill version to a commit SHA, runs security scans and license checks, and benchmarks each skill in a sandbox with and without it, publishing the Lift in percentage points.
- SkillzBench includes a free MCP server plus per-agent loadouts, so each agent only sees the skills and tools you toggled on.
- Both platforms are free to use; MCPServers.org monetizes through sponsor listings, SkillzBench through blog advertising.

The contenders
MCPServers.org is a directory of servers for the Model Context Protocol, billing itself as Awesome MCP Servers. Its index is enormous: the /all page shows 16,671 servers, organized into 14 categories including Development, Productivity, Database, Search, Web Scraping, File System, Version Control, Communication, Cloud Service, Cloud Storage, Marketing, Finance, Design, and Memory. Listings range from official vendor servers (GitHub, Supabase, Atlassian, Playwright, Cloudflare, Context7) to thousands of community-built servers for niche tasks like domain checks, travel eSIMs, and agent-to-agent marketplaces. A dedicated Remote MCP Servers page gives one-click access to official hosted servers from Notion, Linear, Stripe, Slack, HubSpot, Canva, Figma, Mercury, and others, with no local install required, and works with Claude, Codex, Cursor, and any MCP client. The site also publishes focused guides for high-intent workflows such as browser automation. Entries are tagged with an official badge where the vendor maintains the server, and featured slots are marked as sponsor listings. Browsing is free; the directory makes money through sponsors.
pricing 0
- + Largest MCP server index in this comparison by a wide margin: 16,671 listings
- + One-click access to official remote servers removes local setup for tools like Notion, Stripe, and Linear
- + Official badges help you spot vendor-maintained servers at a glance
- + Broad category coverage means nearly any integration need has a candidate server
- + Free to browse with no account friction
- − No security scanning, license checks, or quality scoring of listed servers
- − No benchmarking: you cannot see whether a server actually improves agent performance
- − Sponsor listings sit alongside organic results, which can blur what's featured on merit
- − Listings are developer-oriented; a non-technical owner gets little help judging risk or quality
- − Quality varies wildly across 16,671 community submissions, and the directory doesn't filter for you
SkillzBench is AIQ Labs' free, independent platform for AI agent skills: SKILL.md instruction packages that work with Claude Code, Codex, Cursor, Gemini CLI, and chat-app agents. Its premise is that skills are proliferating faster than anyone can vet them, and published research found roughly 26% of skills carry at least one vulnerability. The platform runs five pillars today. Discover continuously crawls and dedupes skills from GitHub. Verify pins every version to a commit SHA, validates the package, checks the license, runs a security scan, and applies a quality judgment. Benchmark tests every skill in a sandbox with the same model, with and without the skill, and publishes the Lift in percentage points, always shown separately from ratings. Equip provides one free MCP server plus per-agent loadouts: you toggle skills and tools per agent, and the agent only sees what you chose. Stay current tracks upstream changes, re-scans, re-benchmarks, and notifies you. Every skill gets a 0-100 trust score built from security, quality, license, maintenance, and community signals, and money never touches scores. Everything on the platform is free, funded by advertising around blog articles.
pricing 0
- + Directly addresses the ~26% vulnerability rate in agent skills with security scans and version pinning
- + Lift benchmarks give you evidence a skill actually helps, not just that it exists
- + Per-agent loadouts give precise control over what each agent can access
- + Trust scores separate security and quality signals from money and ratings
- + Everything is free, including the MCP connector, benchmarks, and alerts
- + Change tracking means a skill that turns risky upstream gets flagged, not silently swapped
- − Scope is agent skills rather than the full universe of MCP servers, so raw catalog breadth is smaller
- − Benchmark results depend on the model used in the sandbox, so Lift may differ for other models or setups
- − Newer platform, so community signals in trust scores have less history to draw on
- − Revenue comes from blog advertising, which means editorial content sits alongside the product
Verdict
Winner: SkillzBench
For small businesses adopting agents, SkillzBench earns the edge because it answers the question MCPServers.org leaves open: which skills are safe and worth installing. MCPServers.org is the better raw discovery index if you already know exactly which MCP server you want.

FAQ
Are MCPServers.org and SkillzBench both free?
Yes. MCPServers.org is free to browse and funds itself through sponsor listings on its pages. SkillzBench is entirely free as well: the skills directory, the MCP connector, per-agent loadouts, sandbox benchmarks, and change alerts all cost nothing. SkillzBench earns revenue from advertising around its blog articles, and ad money never influences scores or listings.
Do MCPServers.org and SkillzBench compete directly?
They overlap less than you'd think. MCPServers.org is a discovery index for MCP servers, with 16,671 listings across categories like Development, Productivity, and Web Scraping. SkillzBench catalogs and verifies AI agent skills (SKILL.md packages) and benchmarks them for measurable Lift. You'd typically use MCPServers.org to find a server for a specific tool and SkillzBench to vet the skills that shape your agent's behavior.
How risky are unverified agent skills?
Published research found that roughly 26% of agent skills carry at least one vulnerability, so about one in four skills installed without vetting is a potential liability. This is the core problem SkillzBench addresses: every skill version is pinned to a commit SHA, security-scanned, license-checked, and scored on a 0-100 trust scale before you rely on it.
What is Lift in SkillzBench's benchmarking?
Lift is the measurable improvement a skill provides. SkillzBench tests every skill in a sandbox with the same model, once with the skill and once without, and publishes the difference in percentage points. Lift is always shown separately from ratings and money never touches scores, so you can judge usefulness and trust independently. You can see current verified results at skillzbench.com.
Can I use both platforms together?
Yes, and many teams do. A practical pattern: use MCPServers.org to find and connect the MCP server for a tool you already use, such as the official Stripe or Notion remote server, then use SkillzBench to choose and verify the agent skills that tell your agent how to work. One covers infrastructure discovery, the other covers skill quality and safety.
Which platform is better for non-technical business owners?
SkillzBench, for most owners. Its trust scores and Lift numbers can be read without reading code, and per-agent loadouts let you control what each agent accesses with simple toggles. MCPServers.org is excellent but developer-oriented: with 16,671 listings of varying quality, judging which server is safe and well-built falls on you.
