Plugin Types

Skills

Skills provide workflows, procedures, and domain knowledge that Claude loads based on context. Each skill has:

• SKILL.md: Manifest with frontmatter (name, description) and instructions
• scripts/: Optional executable code
• references/: Optional documentation
• assets/: Optional files for output (templates, images)

MCPs (Model Context Protocol)

MCPs provide tools that are always available in Claude Desktop. Each MCP has:

• .claude-plugin/plugin.json: Manifest with name, description, and server configuration
• server.py: MCP server implementation
• config.json: Optional configuration

Quick Start

Create a New Plugin

# Create a skill
python tools/init_plugin.py skill my-skill --path skills

# Create an MCP
python tools/init_plugin.py mcp my-mcp --path mcps

Package a Plugin

python tools/package_plugin.py skills/my-skill
# Creates: my-skill.plugin

Install an MCP

# From packaged file
python tools/install_mcp.py dist/session-memory.plugin

# From directory (symlink for development)
python tools/install_mcp.py mcps/session-memory --symlink

Then add to Claude Desktop config (~/.config/claude/claude_desktop_config.json):

{
  "mcpServers": {
    "session-memory": {
      "command": "python3",
      "args": ["~/.claude/session-memory/server.py"]
    }
  }
}
