How to install Flowsimp in Claude DesktopDesktop app (MCP config)

Open your MCP config
macOS: ~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

Add this server

json

{
  "mcpServers": {
    "flowsimp": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://flowsimp.com/mcp"
      ]
    }
  }
}

Why the wrapper?
This is a remote (HTTP) server and Claude Desktop only launches local processes, so mcp-remote proxies the connection. It will open a browser window if the server needs OAuth.
Restart Claude Desktop
The tools appear under the 🔌 menu once the app reloads.

How to install Flowsimp in CursorAI-first code editor

Create / edit .cursor/mcp.json in your project

How to install Flowsimp in Codex CLIOpenAI coding agent

Add to ~/.codex/config.toml

toml

[mcp_servers.flowsimp]
command = "npx"
args = ["-y", "mcp-remote", "https://flowsimp.com/mcp"]

Why the wrapper?
Codex runs MCP servers as local processes, so mcp-remote bridges this HTTP endpoint to stdio.
Run Codex
Codex loads MCP servers from config.toml on startup and exposes their tools to the agent.

What tools does Flowsimp expose? (2)

Read from the live server. Click any tool for its input schema.

create_flowchartTurn Mermaid flowchart or graph syntax, or an indented outline, into FlowSimp links. Use it when the steps already exist as text and someone needs a diagram they can view or edit. Returns JSON with shareUrl (a read-only /view# link), editUrl (opens the editor at /?board=), nodeCount, and connectionCount. An optional title is echoed in that JSON; it is not drawn on a shape. The diagram is compresse
list_templatesList every built-in FlowSimp template. Use it when a starter diagram is a better fit than generating one from text. Takes no arguments. Returns JSON with a templates array of id, label, and editUrl. The ids are swimlane, decision-tree, user-flow, org-chart, flowchart, process, network, mind-map, data-flow, algorithm, bpmn, onboarding, and approval. Each editUrl opens that template in the editor.

What the code can do

This is a remote server — nothing is installed or run on your machine, so there is no local code to analyze. What it can reach is described above: your requests go to the provider's host.

Documentation

Full README

Flowsimp MCP Server

Create flowcharts from chat. Flowsimp's hosted Model Context Protocol server turns Mermaid flowchart syntax or a plain indented outline into a shareable diagram link and an editable board in the Flowsimp editor.

Endpoint: https://flowsimp.com/mcp
Transport: Streamable HTTP (remote)
Auth: none, no API key or account needed
Price: completely free to use
Registry name: com.flowsimp/flowsimp in the official MCP Registry
Docs: https://flowsimp.com/mcp

The server is stateless. It does not store your diagrams, because each diagram is encoded in the link it returns. Open the editable link to rearrange shapes, edit text, and export PNG or SVG.

This repository holds the public documentation and the registry metadata (server.json, .mcp.json) for the hosted server.

Tools

| Tool | What it does | | --- | --- | | create_flowchart | Builds a flowchart from Mermaid flowchart syntax or an indented outline (up to 16,000 characters). Optional title, and optional mode: flowchart (default) or network. Returns a read-only shareUrl, an editable editUrl, and the node and connection counts. | | list_templates | Lists the built-in templates (flowchart, process, swimlane, decision tree, user flow, org chart, network, mind map) with a link that opens each one in the editor. |

Example create_flowchart input:

json

{
  "text": "flowchart TD\n  A[Start] --> B{Approved?}\n  B -->|Yes| C[Ship it]\n  B -->|No| D[Revise]",
  "title": "Release check"
}

Example result (links shortened):

json

{
  "shareUrl": "https://flowsimp.com/view#…",
  "editUrl": "https://flowsimp.com/?board=…",
  "nodeCount": 4,
  "connectionCount": 3,
  "title": "Release check"
}

An indented outline works too:
