Flowzap

What is Flowzap?

Flowzap turns text prompts into triple-view diagrams (Workflow, Sequence & Architecture) using FlowZap Code DSL, a unique domain-specific language designed for simplicity and AI generation. It is an MCP server that lets AI assistants like Claude, Cursor, and Windsurf create visual diagrams directly from natural language descriptions.

How to use Flowzap?

Install by adding the JSON configuration {"mcpServers":{"flowzap":{"command":"npx","args":["-y","flowzap-mcp"]}}} to any MCP-compatible tool's settings, or run claude mcp add --transport stdio flowzap -- npx -y flowzap-mcp for Claude Code. Once configured, ask your AI assistant to generate, validate, and share diagrams via a playground URL.

FAQ from Flowzap

What makes FlowZap Code different from Mermaid or PlantUML?

FlowZap uses its own unique DSL with only 4 shapes, attribute syntax with colons (label:"Text"), edge labels with equals ([label="Text"]), and required handles for connections — it is not Mermaid and not PlantUML.

Which coding tools are compatible with Flowzap?

Flowzap works with any MCP-compatible tool including Claude Desktop, Claude Code, Cursor, Windsurf IDE, OpenAI Codex, Warp Terminal, Zed Editor, Cline, Roo Code, Continue.dev, Sourcegraph Cody, and others. Replit and Lovable.dev are not compatible.

What security measures does Flowzap have?

The server runs locally, requires no authentication, cannot read your diagrams or account, is SSRF protected (only connects to flowzap.xyz), rate-limited to 30 requests/minute, and enforces a 50KB max code size.

How do I install Flowzap on Windows?

Use the absolute path to npx.cmd, e.g., "C:\\Program Files\\nodejs\\npx.cmd". Find your npx path by running where.exe npx in the command prompt.
