Using the Plugins

Jira MCP Setup Plugin

This plugin installs and configures the mcp-atlassian MCP server, giving Claude Code direct access to Jira via the Model Context Protocol.

Prerequisites

• Python 3
• uv (curl -LsSf https://astral.sh/uv/install.sh | sh)
• jq (brew install jq)
• A Jira API token — generate one at https://id.atlassian.com/manage-profile/security/api-tokens

Setup

/jira-mcp-setup

Or pass all values directly:

/jira-mcp-setup https://mycompany.atlassian.net [email protected] YOUR_API_TOKEN

The skill will:

1. Verify dependencies are installed
2. Ask for Jira URL, email, and API token (if not provided)
3. Create or update .mcp.json in the project root
4. Ask if you want to add .mcp.json to .gitignore (recommended — the file contains your API token)
5. After restarting Claude Code, the Jira MCP server will be available

Plan Refinement Plugin

Use this plugin to refine implementation plans:

/plan-refinement

This skill helps create detailed, well-structured plans for AI execution.

Adding plugin functionality

To add new plugins to this marketplace, follow PLUGINS.md. It describes:

• Directory structure (.claude-plugin/, commands/, agents/, skills/, hooks/, .mcp.json, .lsp.json)
• How to create plugin manifests, commands, agents, skills, hooks, MCP and LSP configs
• A quick checklist for new tools
• Current contents and using skills/plan-refinement/ as a template

Create each plugin under plugins/<plugin-name>/ and, if you use a marketplace manifest (e.g. .claude-plugin/marketplace.json), add an entry there so the plugin is discovered.

Managing marketplaces/plugins (Claude Code)

To discover, add marketplaces, and manage plugins in Claude Code, see the official docs:

• Discover and install plugins — browse marketplaces and install plugins
• Add marketplaces — add from GitHub (owner/repo), Git URLs, local paths, or remote marketplace.json URLs
