Who it is for
A customer checking what is on the menu, what is on offer, and which branch is closest before heading out.
Menu browsing, offers, and restaurant locations
Overview
The official Firehouse Subs app covers three things: locating a nearby restaurant in the chain, reading the menu, and seeing current offers. It comes from the restaurant group behind the sandwich chain.
Menu browsing includes item descriptions and newer additions alongside the standing lineup, so a particular sandwich can be looked up by name. Deals in circulation are listed in the same place. The example prompts point at a named sandwich, the current offers, and the menu for the nearest store.
Ordering ahead is available at most locations rather than all of them, so whether that step is possible depends on which restaurant is selected.

Ordering ahead is stated as available in most locations rather than everywhere, so the flow can stop at browsing.
Availability
Firehouse Subs is listed in the ChatGPT apps directory only. Firehouse Restaurant Group, Inc. has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.

This is an independent catalogue entry compiled by Node8 from Firehouse Subs's public marketplace listing as it stood in August 2026. Listing facts come from the marketplaces; the comparisons against the rest of the directory and any live-endpoint measurements are Node8's. Node8 is not affiliated with Firehouse Restaurant Group, Inc., and inclusion here is not an endorsement.
Node8 builds MCP servers end to end: deciding which tools are worth exposing, the authentication and permission model, the review submissions, and the onboarding that gets them used. One server serves ChatGPT, Claude, and Microsoft Copilot.
