StackOne's MCP turns Jira bug triage into one prompt

|StackOne
When I first connected Jira I had a question about which projects the agent could see, and someone at StackOne answered it straight away. After that it was easy. My agent reads new bug reports in Jira, checks for duplicates, pulls test results from Google Sheets and posts a summary in Slack. It acts as me, so it only touches the projects I have access to.

Automated key business processes seamlessly

|StackOne
LinkLayer gives our AI agent live context across SAP S/4HANA and NCR Voyix, so store managers can ask about stock, sales and supplier orders in one place. We used it to reconcile till sales against SAP inventory overnight, which previously took a finance analyst most of Monday morning. Prompt injection checks screen what comes back from each system before the agent acts, and anything suspicious is flagged on the dashboard. Every request is tied to the individual user, not a shared service account, which got our auditors on side quickly.

Time-saver for a Managing consultant, built for when the team grows

|StackOne
Getting started was straightforward, and I got all the help I needed along the way. I'm setting StackOne up for myself for now, but I love that it's also future-proofing for my first hires: the connectors will already be there, so they'll just need to link their own accounts. I can already get real work done straight from Claude, like creating invoices in FreeAgent, checking what bank transactions still need approving, or pulling up emails, which is a real time-saver. Even better, every time I look at a new tool to bring in, StackOne already covers it, so I can manage everything in one place. Less time on admin, more time on client work!

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.
