# StackOne: products, MCP servers and connect URLs, one vendor page > StackOne (stackone.com): 1 product in The GTM MCP Directory, 1 with an official MCP server, 0 answering a live handshake, 0 tools catalogued.

It is liveness and nothing more: nobody has run its tools. A tool being catalogued means a server names it, by answering tools/list, in its own source, or in the vendor's documentation. None of them has been called. A tool count of 0 means not measured, never zero tools. **Products, 1** ### [StackOne](../tools/stackone.md) A unified-API vendor that publishes a stated 518 managed MCP servers exposing 31,928 tools across HR, CRM, IT and finance applications, reachable through one endpoint with per-account routing, plus dynamic tool discovery so an agent loads only the tools a...

The gate is the api_gate field on each product entry, established by hand on the last_checked date shown above. It records whether a solo operator can get API access without a contract. Money is not tracked. **Jobs the vendor says its products do** No job tag on any product of this vendor. An empty list means nobody has tagged these entries, not that the tools do nothing. **Connect URLs** No product of this vendor records an MCP endpoint or docs URL that the probe could classify. **Command line** ### [StackOne](../tools/stackone.md) stackone official CLI ``` npm install -g @stackone/cli ``` quoted from [https://www.npmjs.com/package/@stackone/cli](https://www.npmjs.com/package/@stackone/cli) on 2026-09-27, via npm harvested 2026-09-27, all on the [tool page](../tools/stackone.md). A CLI being listed means the harvest found an install command or a package on a stated date. Nobody has run it. Every command is quoted verbatim from the URL beneath it. **On GitHub** [github.com/StackOneHQ](https://github.com/StackOneHQ) tied to the vendor by rule 3, account website https://stackone.com has the vendor's domain, confidence strong - **Public repositories**: 34, forks excluded, as read on 2026-09-08 - **Mention MCP**: 4 of them - **Look like CLIs**: 2 of them - **Latest push**: 2026-09-08 The five most recently pushed, on 2026-09-08: | Repository | Kind | Description | Stars | Pushed | Latest release | |---|---|---|---|---|---| | [stack-nudge](https://github.com/StackOneHQ/stack-nudge) | other | | 24 | 2026-09-08 | v1.32.0 | | [stackvox](https://github.com/StackOneHQ/stackvox) | CLI | Offline Kokoro-82M text-to-speech for Python - library, CLI, and a unix-socket daemon for ~13ms speech from shell... | 3 | 2026-09-08 | v0.12.0 | | [defender](https://github.com/StackOneHQ/defender) | CLI | Open source prompt injection protection for Agents calling tools (via MCP, CLI or direct function calling).

A repository count is activity, not a verdict. Read 2026-09-08. **What this page does not claim** A job tag is a vendor claim: it means the vendor says the product does this, and it is not a test result. A listed tool has not been run: the catalogue says what an agent could try, not what works. 1 of 1,252 directory entries are bench tested, meaning somebody personally ran the tool on a stated date, and 0 of this vendor's 1 product are among them. There is no verdict here on whether this vendor is better than another. Vendor pages group the directory's canonical product entries by vendor_domain. The vendor name is the product display name that matches the domain when several products share it; nothing on this page is typed by hand. Data baked 2026-09-27 by build_directory.py (phase 1).
