Stripe

Stripe

The Stripe plugin connects Claude to Stripe's MCP server, enabling AI-assisted payment integration development. It provides best practices guidance for implementing checkout flows, subscriptions, webhooks, and Connect platforms while helping you avoid deprecated APIs and follow Stripe's recommended patterns. Key features include error explanation with code examples in your programming language, test card references organized by scenario, and guidance on modern Stripe APIs like CheckoutSessions, PaymentIntents, and Billing APIs. The plugin steers you toward Stripe-hosted checkout and Payment Element while warning against legacy patterns like the Charges API. How to use: Use /explain-error followed by a Stripe error code or message to get plain English explanations, common causes, and remediation code. Use /test-cards to quickly access test card numbers for different scenarios like declined payments, 3D Secure, or fraud testing. Ask Claude about Stripe best practices when implementing payment flows, and it will guide you using Stripe's recommended CheckoutSessions API and modern payment methods.

Hookify

Anthropic

Create custom hooks via markdown to prevent unwanted behaviors from conversation patterns or explicit instructions.

Greptile

Greptile

Greptile is an AI-powered code review agent that integrates with GitHub and GitLab. View and resolve Greptile's automated PR review comments directly from Claude Code, eliminating context-switching between your terminal and browser. The plugin provides tools for managing pull requests (list, filter by repository/branch/author/status), accessing detailed code reviews, and searching across all Greptile-generated feedback. You can also define and manage custom coding standards and patterns for your organization. How to use: After setting up your Greptile API key, try prompts like "list my open pull requests", "show me the Greptile review for PR #42", "search for comments about error handling", or "trigger a new code review on my current branch".

Remember

Digital Process Tools

Continuous memory for Claude Code: extracts, summarizes, compresses conversations into tiered daily logs.

Linear

Linear

Connect Claude Code to Linear's modern issue tracking platform. This plugin lets you create and manage issues, update statuses, search across your workspaces, and keep your development workflow in sync—all without leaving your terminal. With the Linear plugin, you can quickly file bugs, track feature requests, update project statuses, and query your issue backlog directly from Claude Code. It integrates seamlessly with Linear's fast, streamlined interface designed for product teams. How to use: Ask Claude to interact with your Linear workspace naturally. Try prompts like "create a Linear issue for this bug", "what are my assigned Linear issues?", "update the status of issue ABC-123 to In Progress", or "search Linear for authentication issues".

Firecrawl

Firecrawl

Turn any website into clean, LLM-ready markdown or structured data. Firecrawl integrates powerful web scraping, crawling, and search capabilities directly into Claude Code. Scrape single pages, crawl entire sites, map site structures, and search the web — all with automatic JavaScript rendering, anti-bot handling, and proxy rotation built in. The plugin includes an AI agent for autonomous multi-source data gathering. Just describe the data you need in plain language and the agent finds, navigates, and extracts it across multiple websites — no URLs required. Results can be returned as markdown, HTML, screenshots, links, or structured data matching a custom schema. How to use: After installing, run /firecrawl:setup to configure your API key. Then use these commands to get started: /firecrawl:scrape — Extract a single webpage as clean markdown./firecrawl:crawl — Crawl and extract content from an entire website./firecrawl:search — Search the web and get scraped results./firecrawl:map — Discover all URLs on a site./firecrawl:agent — Describe what data you need and let the AI agent autonomously find and extract it. You can also use Firecrawl's tools directly in conversation: ask Claude to scrape a URL, search the web for information, or gather competitive research across multiple sites. Supports self-hosted Firecrawl instances via custom API endpoint configuration.

Sentry

Sentry

The Sentry plugin brings powerful error monitoring and debugging capabilities directly into Claude Code. Connect to your Sentry environment to analyze production errors, investigate stack traces, and identify patterns across issues—all through natural language queries. The plugin provides real-time access to your error data with severity indicators, user impact metrics, and direct links to Sentry issues. Key features include the issue-summarizer agent for parallel analysis of multiple issues, automatic pattern detection across error types, and root cause investigation with actionable fix suggestions. The plugin quantifies user impact and prioritizes issues by severity, helping you focus on what matters most. How to use: Use /seer followed by natural language queries like "What are the top errors in the last 24 hours?" or "Show me unresolved issues assigned to me." Run /getIssues [projectName] to retrieve recent issues from a specific project. The sentry-code-review skill automatically analyzes and fixes detected bugs in GitHub Pull Requests.

CodeRabbit

CodeRabbit AI

CodeRabbit brings AI-powered code review directly into Claude Code. It provides external validation using a specialized AI architecture and 40+ integrated static analyzers, offering a different perspective that catches bugs, security vulnerabilities, logic errors, and edge cases. The plugin performs context-aware analysis via AST parsing and codegraph relationships, and automatically incorporates your CLAUDE.md and project coding guidelines into reviews. Reviews are organized by severity level: Critical findings (security issues and bugs), Suggestions (code improvements), and Positive feedback (code strengths). The plugin can automatically apply recommended fixes when code generation instructions are available. How to use: Run /coderabbit:review to review your code changes. You can also ask naturally: "Review my code", "Check for security issues", or "What's wrong with my changes?" The review command supports different scopes—review all changes, only committed changes, only uncommitted changes, or compare against a specific branch like main. Prerequisites: Requires installing and authenticating the CodeRabbit CLI before use. The plugin is free to use and works within any Git repository.
