Outflow MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 34 installs a week from npm. Last commit 17 Jul 2026.
MCP server exposing an Outflow workspace's live architecture graph as context for AI coding agents
Nothing serious here today
Today is the operative word: we check Outflow MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

}Put your own values in place of
<OUTFLOW_API_KEY> (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> (ID of the workspace to expose. Found in the workspace URL (.../workspace/<id>/...) or workspace settings).
The author’s registry entry marks them as required.
Optional settings from the registry entry, left out of the block above:
OUTFLOW_BASE_URL (Base URL of your running Outflow instance. Defaults to http://localhost:3000 if omitted).
