FlowZap MCP Server

Create workflow, sequence, and architecture diagrams using AI assistants like Claude, Cursor, Windsurf, and 8 other MCP-compatible tools.

FlowZap is a visual workflow diagramming tool with a text-based DSL called FlowZap Code. This MCP server lets AI assistants create diagrams for you.

What is FlowZap?

FlowZap turns text prompts into triple-view diagrams (Workflow, Sequence & Architecture) using FlowZap Code DSL. It is NOT Mermaid, NOT PlantUML - it is a unique domain-specific language designed for simplicity and AI generation.

Key Facts:

• Only 4 shapes: circle, rectangle, diamond, taskbox
• Node attributes use colon: label:"Text"
• Edge labels use equals: [label="Text"]
• Handles required: n1.handle(right) -> n2.handle(left)
• Lane display label must be on the same line as the opening brace: laneName { # Label
• Sequence diagram quality: every cross-lane request needs a matching response edge before the next major request; define edges in chronological order; keep a strict request → response → next request rhythm; no orphaned nodes

Installation

The FlowZap MCP Server works with any tool that supports the Model Context Protocol (MCP):

All Compatible Coding Tools

Not Compatible: Replit and Lovable.dev only support remote MCP servers via URL. Use the Public API instead.

JSON Configuration

All tools use the same JSON configuration format:

{
  "mcpServers": {
    "flowzap": {
      "command": "npx",
      "args": ["-y", "flowzap-mcp"]
    }
  }
}

Windows Users: If tools don't appear, use the absolute path:

"command": "C:\\Program Files\\nodejs\\npx.cmd"

Find your npx path with: where.exe npx

Usage Examples

Basic Diagram Creation

Ask your AI assistant:

• "Generate a Sequence diagram of the current Sign In flow implemented in this App"
• "Create a workflow diagram for an order processing system"
• "Create an architecture diagram for a microservices API gateway"
• "Make a flowchart showing user registration flow"
• "Diagram a CI/CD pipeline with build, test, and deploy stages"

Agent-Focused Workflows

Parse HTTP Logs into Diagrams:

"Here are my nginx access logs. Create a sequence diagram showing the request flow."

The agent uses flowzap_artifact_to_diagram with artifactType: "http_logs".

Analyze Diagram Structure:

"Which steps in this workflow touch the database?"

The agent uses flowzap_export_graph to get a JSON graph, then queries it.

Show What Changed:

"I updated the workflow. What's different from the previous version?"

The agent uses flowzap_diff to compare old and new code.

Safe Incremental Updates:

"Add a logging step after the API call in this diagram."

The agent uses flowzap_apply_change with a structured patch instead of regenerating.

Compliance Audit:

"Check my data flow diagram for SOC2, GDPR, and PIPL compliance."

The agent uses flowzap_compliance_check to run an automated audit and returns a shareable result page.

Mind Map Creation:

"Create a mind map about AI agent architecture"

The agent uses flowzap_mindmap_template to generate a skeleton, then validates and creates a playground with ?view=mindmap.

The assistant will:

1. Generate FlowZap Code based on your description
2. Validate the code
3. Create a playground URL with the appropriate view (workflow, sequence, or architecture) to view and share

FlowZap Code Example

sales { # Sales Team
  n1: circle label:"Order Received"
  n2: rectangle label:"Submit Order"
  n5: rectangle label:"Receive decision"
  n1.handle(right) -> n2.handle(left)
  n2.handle(bottom) -> fulfillment.n3.handle(top) [label="Submit"]
}

fulfillment { # Fulfillment
  n3: rectangle label:"Review Order"
  n4: rectangle label:"Return decision"
  n3.handle(right) -> n4.handle(left)
  n4.handle(top) -> sales.n5.handle(bottom) [label="Approved"]
}

Public API Endpoints

These endpoints are available for external integrations (no authentication required):

Security

• No authentication required - Uses only public FlowZap APIs
• No user data access - Cannot read your diagrams or account
• Runs locally - The MCP server runs on your machine
• SSRF protected - Only connects to flowzap.xyz
• Rate limited - 30 requests/minute client-side
• Input validation - 50KB max code size
