Skillz
A lightweight MCP server that loads Claude-style SKILL.md skill files and exposes them as callable tools to any MCP-compatible AI agent (Codex, Copilot, Cursor), acting as a universal shim for skill portability across non-Claude clients.

⚙ Agent Friendliness
🔒 Security
Gaming platform API. SDK key auth. Player data is PII — COPPA compliance for minors. Cash prize gaming — verify age and region restrictions.
⚡ Reliability
Best When
You have Claude skills defined in SKILL.md format and want to reuse them with other MCP-compatible agents without platform-specific rewrites.
Avoid When
You need a production-hardened skill management system with audit trails and access control; Skillz is experimental and treats skill code as potentially untrusted.
Use Cases
- • Share Claude skill packs with Codex, GitHub Copilot, or Cursor without rewriting skills for each platform
- • Package and distribute reusable agent workflows as ZIP or .skill archives discoverable by any MCP client
- • Make supplementary resources (scripts, datasets, examples) available to agents alongside skill instructions
- • Run skills in Docker containers for isolated, reproducible agent execution environments
- • Rapidly prototype and test skill libraries using stdio, HTTP, or SSE transport modes
Not For
- • Production deployments requiring enterprise-grade security — explicitly described as an experimental proof-of-concept
- • Teams needing skill versioning, access control, or centralized skill registry management
- • Scenarios where running untrusted skill code is a security concern
Interface
Authentication
No authentication documented. Skills directory access is controlled by the local filesystem and Docker volume mounts.
Pricing
MIT open source with no associated service costs.
Agent Metadata
Known Gotchas
- ⚠ Explicitly described as 'experimental proof-of-concept' — not production-ready
- ⚠ Users advised to treat skill code as untrusted — skills can execute arbitrary scripts
- ⚠ No skill sandboxing or permission model; Docker is the only isolation mechanism
- ⚠ SKILL.md format is tied to Claude's skill convention — not a universal standard
- ⚠ 369 stars and ~102 commits indicates early-stage adoption; API may change
