Symbols.app MCP — docs, code generation, publishing, CLI/SDK reference

symbols-mcp

mcp-name: io.github.symbo-ls/symbols-mcp

MCP server for Symbols.app — provides documentation search, code generation, conversion, auditing, project management, publishing/deployment, and CLI/SDK reference tools for AI coding assistants (Cursor, Claude Code, Windsurf, claude.ai, etc.).

No API keys required for documentation tools. Project management tools require a Symbols account (login or API key).

Tools

Documentation & Generation

Tool	Description
get_project_rules	Returns mandatory Symbols.app rules. Call this first before any code generation task.
search_symbols_docs	Keyword search across all bundled Symbols documentation files.
generate_component	Generate a DOMQL v3 component from a natural language description.
generate_page	Generate a full page with routing integration.
convert_react	Convert React/JSX code to Symbols DOMQL v3.
convert_html	Convert raw HTML/CSS to Symbols DOMQL v3 components.
convert_to_json	Convert DOMQL v3 JS source code to platform JSON (mirrors frank's toJSON pipeline).
audit_component	Audit component code for v3 compliance — returns violations, warnings, and a score.
detect_environment	Detect whether the project is local, CDN, JSON runtime, or remote server.
get_cli_reference	Returns the complete Symbols CLI (@symbo.ls/cli) command reference.
get_sdk_reference	Returns the complete Symbols SDK (@symbo.ls/sdk) API reference.

Project Management & Publishing

Tool	Description
login	Log in to Symbols platform — returns a JWT token.
list_projects	List the user's projects (names, keys, IDs) to choose from.
create_project	Create a new Symbols project on the platform.
get_project	Get a project's current data (components, pages, design system, state).
save_to_project	Save components/pages/data to a project — creates a new version with change tuples, granular changes, orders, and auto-generated schema entries.
publish	Publish a version (make it live).
push	Deploy a project to an environment (production, staging, dev).

End-to-End Flow (from claude.ai or any MCP client)

1. generate_component  → JS source code
2. convert_to_json     → platform JSON
3. login               → get token
4. create_project      → (if new project needed)
   list_projects       → (or pick existing)
5. save_to_project     → push JSON to platform (creates version)
6. publish             → make version live
7. push                → deploy to environment
