drillflow-mcp

Generated. Do not edit here. Every file in this repository is copied from the DrillFlow source repository on each release; changes made here are overwritten by the next sync. Please open issues rather than pull requests.

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:

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

Claude Code:

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.

Licence

MIT — see LICENSE. This covers the MCP server in this repository, not the DrillFlow application.

Issues

Bug reports are welcome in this repository's issue tracker, or by mail to support@drillflow.de.

This server cannot be deployed

One endpoint for every MCP toolRayrun runs every MCP server behind one URL and holds the credentials. Each call is decided per client, tool, and argument, then recorded.ray.runAd
