DrillFlow

Official registry AI and agents

Publish drill-down diagrams from an agent; every Mermaid subgraph becomes a level you enter.

Source code Website Documentation

Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

NPM package drillflow-mcp
Claude Code 
claude mcp add drillflow -e 'DRILLFLOW_TOKEN=<your drillflow_token>' -e 'DRILLFLOW_API_URL=<DRILLFLOW_API_URL>' -- npx -y drillflow-mcp@1.0.94
JSON configuration (Claude Desktop, Cursor, VS Code) 
{
    "mcpServers": {
        "drillflow": {
            "command": "npx",
            "args": [
                "-y",
                "drillflow-mcp@1.0.94"
            ],
            "env": {
                "DRILLFLOW_TOKEN": "<your drillflow_token>",
                "DRILLFLOW_API_URL": "<DRILLFLOW_API_URL>"
            }
        }
    }
}

Environment variables

  • DRILLFLOW_TOKEN secret A DrillFlow API token (Pro). Without it the server still publishes, but anonymously: the link is unowned, unlistable and expires after 72 hours, and every result says when.
  • DRILLFLOW_API_URL Override the API origin. Defaults to https://api.drillflow.de; only useful against staging.

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

ToolWhat it does
publish_diagramPublishes a DrillFlow document, returns the share URL.
publish_mermaidConverts a Mermaid flowchart (subgraphs → subflows) and publishes it.
read_diagramReads 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

VariableMeaning
DRILLFLOW_TOKENAn API token from Your account → API tokens at app.drillflow.de. Optional.
DRILLFLOW_API_URLDefaults 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 72 hours (the result names the exact time). 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.

Frequently asked questions

What is DrillFlow?

Publish drill-down diagrams from an agent; every Mermaid subgraph becomes a level you enter.

How do I install DrillFlow?

It runs on your machine. In Claude Code: claude mcp add drillflow -e 'DRILLFLOW_TOKEN=<your drillflow_token>' -e 'DRILLFLOW_API_URL=<DRILLFLOW_API_URL>' -- npx -y drillflow-mcp@1.0.94. For other clients, paste the JSON configuration from this page into their MCP settings.

Does DrillFlow need an API key?

Yes. It expects DRILLFLOW_TOKEN, which you set in its configuration.

Is DrillFlow open source?

Yes. Its code is on GitHub under the MIT license.

Who maintains DrillFlow?

It is published by capydev42. AI.tn lists it but does not maintain or endorse it.

From the official MCP Registry. Listing is not an endorsement: review a server's code and permissions before giving it access to your data.
