Overview

Description from the maker (original English)

Create workflow, sequence, architecture, and mind map diagrams via AI assistants.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

You need

  • Runs in the cloudNothing to install; it connects over the internet
  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Common questions

Is Flowzap safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (2.1.0) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

FlowZap MCP Server

Create workflow, sequence, architecture, and mind map 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 quad-view diagrams (Workflow, Sequence, Architecture & Mind Map) 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):

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:

`json

"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.

Repair Invalid Code:

"My FlowZap Code fails validation. Fix the mechanical errors for me."

The agent uses flowzap_fix to deterministically repair numbering, inferred handles, label syntax, lane labels, emoji and control characters, then validates the repaired code. Anything the repairer cannot fix is reported as-is — it never invents content.

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):
