# Muse from Meta on Mac: Monitor Its Network Access with FireAI > Muse is described by Meta as a personal AI agent. What is verifiable about it, and how to watch its network connections on a Mac with FireAI and flag a new destination. FireAI Security & Research Team (HisnLabs) · Published 2026-10-04 Canonical: https://hisnlabs.com/en/blog/monitor-muse-meta-network-mac-fireai Muse is the name Meta uses for a personal AI agent and a family of models. This article is intentionally limited to what Meta's own page states and to what FireAI documents, because the Meta pages fetched for this article gave little technical detail about how the Mac app works. ## What Meta says Muse is Meta's AI page describes Muse as "your personal AI agent" and as "The World's First Personal AI Agent Built for Everyone". It names several models: Muse Spark 1.3, which "delivers improved performance across agentic and coding tasks"; Muse Spark 1.2, which brings "a terminal coding agent, Muse Code"; and Muse Image, an image generation model ([ai.meta.com](https://ai.meta.com/)). > **Note:** Unverified for this article: how the Muse app for Mac is distributed beyond what FireAI documents, its permission model, its data retention terms and any list of domains. The Meta AI site (meta.ai) returned an access error to the tools used. Check Meta's documentation and privacy policy directly. ## What follows from an agent that acts for you Meta describes an agent rather than a chat window, and describes a terminal coding agent among the models. Software that acts on your behalf can contact services on your behalf. Whether it does so only to Meta's servers or also to others is exactly the kind of question that a record of destinations answers on your own machine. ## Watching Muse from Meta with FireAI FireAI is a firewall for macOS that runs on your Mac. Its [Agent profile](https://hisnlabs.com/en/docs/agent-profile) feature recognises 19 AI agents, Muse from Meta among them, and identifies Muse from Meta by its App Store identifier. FireAI then learns where that app normally connects. For every recognised agent it works the same way, using only metadata (host names and byte counts); FireAI never reads the payload of a connection. 1. For the first 3 days FireAI learns the destinations Muse from Meta normally contacts, grouped by domain: api.anthropic.com becomes anthropic.com. Nothing is flagged during this learning period. 2. After that, a destination outside the learned baseline is flagged for review in Suggestions, in the AI agents card and in Quick Review. Swipe left to block, or right for "It's fine". 3. An upload spike is flagged too: an hour in which the agent uploaded at least 4 times its busiest hour so far, and never less than 25 MB. ## Set up monitoring for Muse from Meta, step by step 1. Install and open FireAI, then use Muse from Meta as you normally would for a few days so the 3-day learning period has real traffic to learn from. 2. Open Suggestions and look for the AI agents card. Flags from agents also appear in Quick Review, the card stack you swipe through. 3. To keep the agent to the places it already uses, choose Agent profile in the security mode menu, next to Home, Coffee shop, Paranoid and Under attack. Once the agent has finished learning, a connection to a destination outside its baseline is blocked instead of being flagged. Your own allow rules still win, and DNS and your local network are never blocked. 4. When something is blocked, the AI agents card offers Allow and Keep blocked. Allow adds the destination to the baseline; Keep blocked creates a block rule, so the destination stays blocked in every mode. 5. For a precise rule, open Rules and click Add rule: choose the app, then Allow or block, then a website, a domain with its subdomains, an IP address or a range, and how long it lasts. 6. To understand a single connection, open Threats and use Investigate, or choose Investigate from a line on the World map. The page shows a risk score, the reasons behind it and what FireAI saw. > **Note:** The Agent profile mode needs FireAI 1.0.3 or later, and the 19-agent list needs 1.0.4. Version 1.0.2 flags new destinations but does not block them. ## Limits - FireAI cannot see prompts, the contents of tools, file access such as ~/.ssh, or skills. TLS hides the payload, and FireAI is not inside Muse. - FireAI does not stop prompt injection. It limits the damage by flagging, and letting you block, the path data would take out of your Mac. - During the 3-day learning period nothing is flagged, and in the Agent profile mode nothing is blocked while an agent is still learning. Upload spikes are flagged, never blocked. - Agents matched by app, path or script name are labelled, not verified: only Claude Code, Claude and Cursor are checked against their developer's signature. - Child processes that exit very quickly may be missed, and they are matched by path, not by signature. - A Muse feature that runs inside a different program, such as a terminal tool, is only attributed to Muse if FireAI recognises that program; otherwise it falls back to connection prompts and per-app rules. The full feature description is on the [Agent profile documentation page](https://hisnlabs.com/en/docs/agent-profile). > Muse acts on your behalf. FireAI tells you when it reaches somewhere it has never been.

FireAI is HisnLabs’ own product: an on-device AI firewall for Mac. It shows every connection your apps make, in plain language, and lets you decide what leaves your Mac — its AI runs locally, so your traffic is never sent to us or anyone else. HisnLabs’ security research team is the group that keeps that decision-making accurate: cataloguing which domains are ordinary telemetry versus a real product, tracking the country and network behind a connection, and training the on-device model (its FireAI Pilot feature) on real traffic patterns, all without any of it leaving your Mac. You can read the technical decisions behind it, or try FireAI for 17 days, at [FireAI, by HisnLabs](https://hisnlabs.com/en/download). ## Sources - [Meta AI: ai.meta.com](https://ai.meta.com/) - [FireAI docs: Agent profile](https://hisnlabs.com/en/docs/agent-profile) - [FireAI docs: Rules](https://hisnlabs.com/en/docs/per-app-rules) - [FireAI docs: Security modes](https://hisnlabs.com/en/docs/security-modes) - [FireAI docs: Answer your first connection prompt](https://hisnlabs.com/en/docs/answer-your-first-connection-prompt) - [FireAI docs: Investigate a connection](https://hisnlabs.com/en/docs/investigate-a-connection)
