Flowgraf is an MCP server with 3 tools an agent can call, among them create_diagram, edit_diagram, get_diagram. It answers at https://flowgraf.in/api/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 10 September 2026; the last check, on 19 October 2026, succeeded.
Create and edit architecture diagrams from your AI agent; get an SVG and a live editable canvas.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
create_diagram | Create a NEW architecture diagram from a graph that YOU author, and get back a shareable, editable canvas URL plus a rendered SVG and Mermaid. You produce only the SEMANTICS — nodes, the groups (VPC/cluster/...) they live in, and the direct Inputs: title, graph, domain |
edit_diagram | Apply a list of operations to an EXISTING diagram. The ops re-use this tool's op vocabulary; you author them, we validate + apply + re-layout + re-render. ALWAYS call get_diagram(diagramId) first: it returns the current ids and the `version |
get_diagram | Fetch a diagram's raw IR (nodes, groups, edges with their real ids) and its current `version`. Call this before edit_diagram so your ops reference ids that actually exist and you pass the correct baseVersion. Returns { diagram, version }. Inputs: diagramId |

Yes. It is published by flowgraf.in and served from flowgraf.in, the vendor's own domain: https://flowgraf.in/api/mcp.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://flowgraf.in/api/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: in.flowgraf. Endpoint host: flowgraf.in. ARD identifier: urn:air:in.flowgraf:mcp:flowgraf.
First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
