Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "outflow": {
      "command": "npx",
      "args": [
        "-y",
        "outflow-mcp"
      ],
      "env": {
        "OUTFLOW_BASE_URL": "your-value",
        "OUTFLOW_API_KEY": "your-value",
        "OUTFLOW_WORKSPACE_ID": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add outflow --env OUTFLOW_BASE_URL=your-value --env OUTFLOW_API_KEY=your-value --env OUTFLOW_WORKSPACE_ID=your-value -- npx -y outflow-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "outflow": {
      "command": "npx",
      "args": [
        "-y",
        "outflow-mcp"
      ],
      "env": {
        "OUTFLOW_BASE_URL": "your-value",
        "OUTFLOW_API_KEY": "your-value",
        "OUTFLOW_WORKSPACE_ID": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "outflow": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "outflow-mcp"
      ],
      "env": {
        "OUTFLOW_BASE_URL": "your-value",
        "OUTFLOW_API_KEY": "your-value",
        "OUTFLOW_WORKSPACE_ID": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

OUTFLOW_BASE_URL env
Base URL of your running Outflow instance. Defaults to http://localhost:3000 if omitted.
OUTFLOW_API_KEY secret required env
API key for the workspace to expose. Create one from workspace settings in Outflow (Settings → API Keys) — the raw key (ofk_...) is shown once.
OUTFLOW_WORKSPACE_ID required env
ID of the workspace to expose. Found in the workspace URL (.../workspace/ /...) or workspace settings.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Outflow MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: OUTFLOW_API_KEY, OUTFLOW_WORKSPACE_ID

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.1) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

outflow-mcp

An MCP (Model Context Protocol) server that exposes a live Outflow architecture graph as context for AI coding agents — Claude Code, Claude Desktop, or any other MCP-compatible client. Lets an agent ask "what does this file depend on", "what breaks if I change this", or "did my last batch of edits introduce a circular dependency" against your workspace's real, currently-live graph.

It's a thin client over Outflow's existing /api/v1 REST API and the workspace graph routes — no graph logic is duplicated here.

This package is developed inside the main Outflow monorepo but published

from a standalone public mirror: https://github.com/laurells/outflow-mcp

— that's the repo MCP registries/crawlers point at, and where npm publish

runs from. Changes here get synced there before each release.

Setup

Create an API key for the workspace you want to expose. In Outflow, go to workspace settings → API Keys → create one. The raw key (ofk_...) is shown once — copy it.
Find your workspace ID — it's in the workspace URL (.../workspace/ /...) or workspace settings.
Build the server:

   cd packages/mcp-server

npm install npm run build

4. **Add it to your MCP client config.** For Claude Code, add to your MCP

settings (claude mcp add or the equivalent config file):

"mcpServers": { "outflow": { "command": "node", "args": ["/absolute/path/to/outflow/packages/mcp-server/dist/index.js"], "env": { "OUTFLOW_BASE_URL": "https://your-outflow-domain.com", "OUTFLOW_API_KEY": "ofk_...", "OUTFLOW_WORKSPACE_ID": "your-workspace-id" } } } }

   For local development, `OUTFLOW_BASE_URL` defaults to `http://localhost:3000`

if omitted.

Tools

Tool	Use it to ask
`find_node`	Is this file tracked? What's its ID?
`list_nodes`	What's deprecated / low health / a given type?
`get_dependencies`	What does this file rely on?
`get_impact`	What breaks if I change this file? (blast radius)
`find_path`	How are these two files connected?
`get_architecture_health`	What's the overall health grade and at-risk nodes?
`find_architecture_smells`	Any circular deps, god nodes, or dead code right now?
`get_architecture_graph`	Give me the whole graph at a zoom level.
`get_last_session_recap`	What happened in my last coding session?

All tools that take a path accept a partial match (e.g. "ApiClient" will match src/ApiClient.ts) — you never need to know Outflow's internal file::/method:: ID format. An ambiguous partial match returns an error listing the candidates instead of guessing.

Notes

This package is standalone — it is never bundled into server/ or web/, and has no build-time dependency on them. It only talks to a running Outflow instance over HTTP using an API key, so it works equally well pointed at localhost or a deployed instance.
get_dependencies/get_impact and find_architecture_smells/find_path call workspace graph routes that (as of this package's introduction) were extended to accept Authorization: Bearer ofk_... alongside the existing cookie-session auth — see server/src/graph/pathRouter.ts and smellsRouter.ts.
