The Isa Hub is the view inside Isa that connects to the Community Hub. It’s where you browse, download, and remove Agents, Scribe Agents, and MCP Servers — everything other clinicians have built and published. The Isa Hub catalog filters by type — every item, only what you’ve already installed, only Agents, only MCP Servers, only Scribe Agents. Search runs against the type you’ve picked, so narrow the filter first if you want to limit the scope. Open a row to see the full details and the action you can take on it.

​
Download an Agent

An Agent’s detail view shows the model it runs on (e.g. mlx-community/Qwen3-1.7B-4bit), the Slash Commands the author bundled, and the Environments the Agent is available in — Patient, Workspace, or both. Download it from here and Isa pulls the Agent’s metadata and its on-device model files. Downloading a community-built Agent first shows a disclaimer: Isaree doesn’t review or validate its clinical accuracy, and by continuing you accept responsibility for reviewing its outputs before use.
Model files are large, so a download can take a while. It keeps running when you switch apps or lock your device, and the progress bar tracks the bytes actually transferred. On iPhone, a Live Activity on the Lock Screen and in the Dynamic Island shows the progress and lets you stop the download without opening Isa. Pausing keeps the files already downloaded — resuming continues instead of starting over. Isa notifies you when a download that finished in the background is ready to use.
Once downloaded, the Agent appears under the Installed filter and shows up in the pickers that match its Environments — @ in Patient Chat for the Patient Environment, Pick an agent in Workspace for the Workspace Environment.

​
Install an MCP Server

An MCP Server’s detail view shows its category, the Configuration fields it needs, and the Available Tools it exposes. Configuration fields marked with a red asterisk are required — typically an API key or bearer token. Fill them in before you install; the Primary Agent calls the server’s tools using the credentials you provide here. Local MCP Servers — packages that run on your own machine — install on the Mac only, and the runtime their config calls (Node for npx, Python for uvx) has to be installed there. See MCP servers.
Only the Primary Agent calls MCP Servers today. Agents invoked with @ can’t (yet).

​
Download a Scribe Agent

A Scribe Agent’s detail view shows the Templates it ships (each with the number of structured output fields it produces) and the Models it uses for transcription. Download it from here and its templates show up in Select Template when you start a Scribe session from a Patient Chat.

​
Remove something you’ve installed

The detail view for an item you’ve already installed replaces the download action with a remove action — same view, different button. Removing an Agent doesn’t delete patient data; only the Agent and its model files leave the device.

​
Understand what stays on your device

Everything you download from the Isa Hub — Agents, Scribe Agents, MCP Server registrations, model files — lives on the device you downloaded it on. Nothing syncs to your other devices. Deleting Isa removes all of it. What each downloaded item sends off-device when you use it is a separate question — a cloud Scribe Agent sends audio to ElevenLabs, an MCP Server sends whatever the Primary Agent passes it. See Data and privacy.
