Centralized AI Connections and Visibility Across Engineering Tools

|StackOne
What I like is that it takes some of the admin out of using AI across our engineering tools. I don't want every new connection to turn into another bit of glue code we have to look after. Having the connections and permissions in one place makes that side of things easier. The visibility is useful too. I can see which person an action belongs to and which tools are getting used. That gives me a clearer picture of how the team is using AI as we open it up to more people, and helps me work out where it's actually useful.

StackOne's MCP Allows Our ChatGPT To Automate Our Weekly Marketing Round Up

|StackOne
I'm an early user of StackOne. Currently, every Monday I pull together what campaigns we sent, what's coming up and what press we picked up. I added StackOne into ChatGPT, and it can now read the plans in Google Drive, checks the team's updates in Slack and drafts the round-up as a Google Slides deck. I tidy it and share it. Setting up each connection took a couple of minutes. This is all stuff ChatGPT can do, but I like having it managed in one place, where I can track the success of each tool call. I find the dashboard very intuitive to use, which allows me to develop my connectors further

What is StackOne?

StackOne is the Tool Gateway for successful AI rollouts across teams and systems. It manages the tool layer between AI agents and business applications, giving organizations shared, governed and secured access to business systems without every team building and maintaining separate integrations. StackOne provides managed connectors for business applications and pre-built actions via an MCP gateway, A2A, AI SDKs and APIs, plus an AI Connector Builder to extend connectors or connect custom and legacy systems. Tool discovery and token optimization surface only relevant tools, keeping context lean. Managed authentication and granular permissions govern access for every user, agent and action; prompt-injection defense and reliable, secure execution protect against unsafe or malicious tool responses; and end-to-end observability captures tool calls, actions, failures and audit trails. StackOne has raised $24 million and is backed by GV (Google Ventures) and Workday Ventures.
