Brand rules for AI outputs. Validate and rewrite text to match your brand voice.
Brand rules for AI outputs. Validate and rewrite text to match your brand voice. The stylemcp mcp server wraps that behind the Model Context Protocol, so an assistant can use it through 14 defined tools rather than through you.
Executable brand rules for AI models and agents. Keep every AI-generated message on-brand.
StyleMCP validates and rewrites AI-generated text to match your brand voice. Use it as:
Everything the assistant can do here goes through one of these:
Method — EndpointPOST — /api/validateGET — /api/packsvalidate_text — Validate text against brand rulesrewrite_to_style — Rewrite text to match brand voiceget_voice_rules — Get voice and tone guidelinesget_copy_patterns — Get approved copy patternsget_cta_rules — Get CTA guidelinesget_tokens — Get design tokenslist_packs — List available style packsManual — The Manual tool exposed by this serverVocabulary — The Vocabulary tool exposed by this serverInstallation goes through your MCP client rather than a global install: point it at stylemcp on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
You will need 2 environment variables: STYLEMCP_API_KEY, GITHUB_WEBHOOK_SECRET. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Stylemcp's toolset — Method, POST, GET and 11 more — is a fair guide to whether it matches your workflow. It is maintained by 3DUNLMTD; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
