About DrillFlow
DrillFlow is an MCP server for turning Mermaid flowcharts into navigable hierarchical diagrams and publishing them as read-only links. It is intended for agents that create, share, or retrieve DrillFlow diagrams.
Key features
- 01Publish DrillFlow documents
- 02Convert and publish Mermaid flowcharts
- 03Turn subgraphs into navigable subflows
- 04Read published diagrams
Use cases
- 01Publish a Mermaid flowchart as a hierarchical diagram
- 02Share a read-only diagram link
- 03Retrieve an existing DrillFlow diagram
MCP support
It exposes tools for publishing DrillFlow documents, converting and publishing Mermaid diagrams, and reading published diagrams to MCP clients. Publishing requires host confirmation and creates a public read-only link.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
npx -y drillflow-mcpDRILLFLOW_TOKENSecretA 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_URLOverride the API origin. Defaults to https://api.drillflow.de; only useful against staging.Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

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 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.
