CardZero

Turn product usage events into invoices for subscription, consumption-based, or hybrid pricing. The API-first platform combines metering, entitlements, automated billing, payment retries, gateway orchestration, and revenue reporting while remaining payment-processor independent. Teams can use its cloud service or run the open-source stack with Docker Compose and connect through REST APIs and SDKs. Self-hosted deployments collect basic action analytics by default; the documentation excludes customer PII and financial data and provides an opt-out.

tradingview-mcp exposes market quotes, screeners, technical indicators, sentiment, and strategy backtests for stocks, crypto, forex, and futures through MCP. It can be self-hosted for free or used through a managed connector. The server does not sign in to TradingView or place trades, and it is an independent project using third-party data that may be delayed or incomplete; its outputs are informational rather than financial advice.

Use this collection to equip coding and general-purpose agents with workflows for financial news, stock data, sentiment analysis, forecasting, signal tracking, visualization, and report generation. Individual skills can be installed with npx or copied into supported agent directories for Claude Code, Codex, OpenCode, and related tools. It is a modular skill pack rather than a standalone investment research application.

This collection provides domain-focused Claude skills for security, privacy, legal, and governance work across frameworks such as ISO 27001, SOC 2, GDPR, HIPAA, FedRAMP, PCI DSS, and the EU AI Act. The skills support gap assessments, first-draft policies, control narratives, evidence preparation, document review, and technical recommendations tied to specific regulatory requirements.
