In their own words
StyleMCP
StyleMCP checks AI-generated copy against brand rules, provides scores and actionable fixes, and can rewrite drafts to fit a brand voice. Its Learn My Voice feature analyzes supplied content to produce custom style rules. Users can start with SaaS, E-commerce, Healthcare, and Finance style packs or define rules in YAML. The AI Trust Layer is described as identifying voice drift, compliance risks, and hallucination patterns. Connections include MCP support for Claude and Cursor, a REST API, CLI, and GitHub Actions for CI/CD; the maker says it works with Claude, GPT, Llama, and any model. The core validation engine is open source and can run on a user's infrastructure with Docker Compose. The free plan includes 5,000 requests per month; Pro costs $9 a month and includes 25,000 requests. Each validate, rewrite, or batch API call counts toward usage, with batch requests counted by items. When a quota is exceeded, API requests return a 429 error until the monthly reset on the first.
