Flowgraf MCP server (stdio proxy) — create & edit architecture diagrams from your AI agent; returns an SVG + a link to a live, editable canvas. No API key.
Overview
From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.
Create and edit clean, editable architecture diagrams from your AI agent — in plain English.

Flowgraf turns a description of a system into a clean, auto-laid-out architecture diagram — then hands back a link to a live canvas you can keep editing, by chat or by hand. This package is the stdio proxy for MCP clients that speak stdio: it forwards to Flowgraf's hosted MCP endpoint. No API key, no LLM cost to you — your agent authors the diagram, Flowgraf lays it out and renders it.
npx -y flowgraf-mcp
Why
Drawing architecture diagrams by hand is slow and rots the moment the system changes. With Flowgraf, you describe the system once and get a diagram you can edit semantically — "add a Redis cache between the API and the database" — and the edges re-route themselves.
Before: hand-drawn, manual layout After: describe it, get a laid-out diagram
Tools
The proxy forwards Flowgraf's tool list verbatim, so it always mirrors what the server exposes. Today that's three tools:

Questions
What is the flowgraf MCP server?
Flowgraf MCP server (stdio proxy) — create & edit architecture diagrams from your AI agent; returns an SVG + a link to a live, editable canvas. No API key.
What tools does flowgraf expose?
3 in total: 1 read-only, 2 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.
Is flowgraf safe to connect to an agent?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.
What credentials does flowgraf need?
No credential environment variables were found in its source, so it appears to need none.
How does flowgraf run?
It speaks stdio and streamable-http, so it runs as a local process your client starts. It is published on npm as flowgraf-mcp at 0.1.2.
How current is this page?
The grade is for one exact copy of the source (b57f7a140c36), read on 2026-10-13. The repository is watched and re-audited when it changes.
