Who it is for
Estimators and preconstruction teams working takeoffs and estimates in STACK.
STACK
Construction takeoffs and estimates queried and updated in words
Overview
What STACK does
STACK is construction takeoff and estimating software, and this connector reaches an account without code or installation.
Reading covers searching projects and takeoffs, opening and reviewing estimates, and looking things up in takeoff libraries. Writing goes further than most: new projects can be started, including directly from an invitation-to-bid email, project details updated, and bulk edits made. That first path is the interesting one, since turning a bid invitation into a project is the step that usually begins by hand. Community tier, documentation published.
Tool surface
Credentials gate the endpoint, so nineteen is the listing's count. Project and takeoff search, estimate review, library lookup, project creation and bulk edits are the groupings described.
Availability
Where STACK is listed
STACK is listed in the Claude connectors directory only. STACK Construction Technologies has no app under the same domain in the ChatGPT directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
The MCP server behind a Claude connector is usually the same server a ChatGPT app would need, so the absence is a distribution decision rather than a technical one.
Claude listing
In the Claude connectors directory
STACK publishes 19 tools to Claude, deeper than 67.2% of the 1,253 Claude-listed connectors.
The median Claude-listed connector filed under Productivity publishes 12, so this one runs 7 tools above its bucket's median and ranks 168th of 462 by tool count.
It falls in the 11-20 tools band, which holds 22.5% of the Claude directory.
STACK publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally.
Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there.

In the publisher's words
How STACK Construction Technologies describes it
STACK is a construction takeoff and estimating platform used by estimators and preconstruction teams. This connector links your AI assistant to your STACK account so you can work with your projects, takeoffs, and estimates just by describing what you want — no code, and nothing to install. Once connected, your assistant can: • Find and review existing work — search projects and takeoffs, open and review estimates, and look things up in your takeoff libraries. • Create, update, and import — start new projects (including straight from an invitation-to-bid email), update project details, make bulk edits to takeoffs, and import from your libraries and company lists. You stay in control. You sign in on STACK's own secure page using standard OAuth 2.0 — your assistant never sees your password. A STACK-branded approval screen lets you choose exactly which capabilities to grant, and you can allow read-only work (finding and reviewing) without allowing changes. Before it creates, updates, or imports anything, your assistant shows you what it's about to do and waits for your approval. Your existing STACK permissions always apply: the connector can only see and change what you already could, and STACK enforces the same company ownership and user permissions it always has.
