SEPs and Proposals

Proposal Venue Description
SEP-2076 MCP Spec Agent Skills as a first-class MCP primitive
SEP-2093 MCP Spec Resource Contents Metadata and Capabilities: scoped resources/list, per-resource capabilities, resources/metadata endpoint
PR #2527 MCP Spec Recommend clients expose resource read to models — prerequisite for the resources-based skills approach
skills.json format proposal MCP Registry Skills metadata in registry schema

Working Group Member Implementations

Work by WG leads and active participants that directly implements the group's core patterns: SKILL.md with YAML frontmatter, skill:// resource URIs, and progressive disclosure via MCP primitives.

Implementation Author Organization URL Notes
skilljack-mcp Ola Hungerford Nordstrom github.com/olaservo/skilljack-mcp SKILL.md, skill:// resources, tools, and prompts; progressive disclosure (index→skill→files); file watching for dynamic updates; audience annotations
skills-over-mcp Keith Groves github.com/keithagroves/skills-over-mcp SKILL.md, skill:// resources with progressive disclosure (index→skill→documents); Zod validation against Agent Skills spec
skillsdotnet Peder HP github.com/PederHP/skillsdotnet C# implementation: SKILL.md, skill:// resources, load_skill tool for progressive disclosure, manifest with file hashes; published on NuGet; compatible with FastMCP 3.0

Alternative Approaches

Work by WG members and MCP maintainers that explores skills over MCP through different technical approaches than the core SKILL.md / skill:// pattern.

Implementation Author Organization URL Notes
skillful-mcp Kurtis Van Gent Google Cloud github.com/kurtisvg/skillful-mcp Progressive disclosure via 4 lightweight tools (list_skills, use_skill, read_resource, execute_code); wraps downstream MCP servers as skills using mcp.json config rather than SKILL.md; sandboxed code execution via Monty
Astronomer agents Kaxil Naik Astronomer github.com/astronomer/agents Production skills catalog for Apache Airflow (blueprint, migration, warehouse-init); uses SKILL.md frontmatter but distributed via plugin marketplace rather than MCP resources; demonstrates real-world skills adoption at scale
mcpGraph skill Bob Dickinson TeamSpark.ai github.com/TeamSparkAI/mcpGraph Declarative YAML-based tool orchestration engine (directed graphs of MCP tool calls); includes SKILL.md files as documentation; explores a complementary "no-code composition" approach to skill authoring

Specifications and Standards

  • Agent Skills Standard: agentskills.io
  • Agent Skills Discovery RFC v0.2.0 (Matt Silverlock / Cloudflare): github.com/cloudflare/agent-skills-discovery-rfc — Domain-level skill discovery using /.well-known/agent-skills/ (RFC 8615). Defines index.json with progressive disclosure, skill-md and archive distribution types, $schema versioning, SHA-256 content integrity, and archive safety requirements. Complementary to MCP-level discovery: .well-known answers "what skills does this domain publish?" while MCP answers "how does the agent consume them at runtime?"
  • Skill dependency declaration: agentskills/agentskills#110 — Discusses how skills should declare their tool/server dependencies
  • Apache Airflow AIP-91 (MCP integration): cwiki.apache.org/…/AIP-91+-+MCP
