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"]
}
}
}
