An MCP server for DrillFlow — the diagram editor built around drill-down, where a node can own a whole sub-diagram you navigate into.

With this server an agent can turn a Mermaid flowchart into a real hierarchical diagram, publish it to a shareable read-only link, and read published diagrams back. Every subgraph becomes a subflow a reader can actually open, which is what a flat picture cannot do.

Install

Claude Desktop (claude_desktop_config.json) or any MCP host:

json

{
  "mcpServers": {
    "drillflow": {
      "command": "npx",
      "args": ["-y", "drillflow-mcp"],
      "env": { "DRILLFLOW_TOKEN": "dfp_…" }
    }
  }
}

Claude Code:

bash

claude mcp add drillflow --env DRILLFLOW_TOKEN=dfp_… -- npx -y drillflow-mcp

Node 20 or newer.

Tools

Tool	What it does
`publish_diagram`	Publishes a DrillFlow document, returns the share URL.
`publish_mermaid`	Converts a Mermaid flowchart (subgraphs → subflows) and publishes it.
`read_diagram`	Reads a published diagram back as its document — share URL, `@handle/name` address or slug.

Publishing puts the diagram on a public read-only URL that anyone holding the link can open. Nothing is published without the host asking you first.

Configuration

Variable	Meaning
`DRILLFLOW_TOKEN`	An API token from Your account → API tokens at app.drillflow.de. Optional.
`DRILLFLOW_API_URL`	Defaults to `https://api.drillflow.de`.

Without a token the server publishes anonymously, and says so in every result: nobody owns the link, it cannot be listed or revoked, and it stops working after 90 days. With a token the link belongs to your account — listed under My shared links, renameable, revocable, no expiry.

Format

The document format is documented at https://drillflow.de/en/format/, with a JSON Schema at https://drillflow.de/schema/drillflow-document.schema.json. There is also a Claude Skill for generating DrillFlow diagrams: capydev42/drillflow-skill.

Building

This repository holds the server's own sources, which is what the MIT licence below covers. It is not a standalone build: the package bundles a few modules from the (closed-source) DrillFlow editor — the Mermaid importer and the document validator — so the published drillflow-mcp on npm is built from the DrillFlow repository, not from here. Install it with npx; read it here.
