Stylemcp

Turns brand voice guidelines into executable rules that AI models can validate against before generating text. Exposes tools for checking text compliance, rewriting copy to match your style, and fetching approved patterns and CTAs. Ships with pre-built packs for SaaS, ecommerce, healthcare, and finance that catch things like forbidden jargon, weak CTAs, and accessibility issues. You can also define custom packs using YAML files with vocabulary preferences, regex patterns to avoid, and tone attributes. Runs as an MCP server for Claude, a REST API for any app, a CLI for CI/CD pipelines, or a GitHub Action to block off-brand copy in pull requests. Useful when you need consistent voice across multiple AI agents or want to enforce brand rules programmatically instead of through style guides.
