StackOne
PluginStackOne's official plugin connects its hosted MCP so agents can search and act across hundreds of connected business systems, from HR platforms like Workday and SAP to CRMs and Jira, for example looking up leave requests. Needs a StackOne account (free plan available) with your systems connected.
StackOne plugin
Give AI agents 30,000+ safe, token-optimized actions across Workday, SAP, Oracle + hundreds more.
This plugin connects your agent to StackOne's hosted MCP server. Install it once, sign in with your StackOne account, and the agent can search for and run actions across every connector linked to that account. One repo, one plugin, loads in Grok Build, Cursor, Claude Code, Codex and ChatGPT.
StackOne is the AI Agent Integration Platform. Tool calling is safe and token-optimized: Defender, StackOne's safety model, screens every call in real time; Advanced Tool Search (ranked #1 for tool search accuracy on public benchmarks) and StackOne Query keep token usage and latency low. StackOne handles authentication, rate limiting, and multi-tenancy across every connector.
Install
| Host | How |
|---|---|
| Grok Build | /marketplace → find stackone → i. Or grok plugin install stackone --trust. Then /mcp → stackone → i to sign in. |
| Cursor | Marketplace → StackOne → Install, or /add-plugin stackone. Sign in when Cursor prompts. |
| Grok Bot | Settings → Plugins → Marketplace → StackOne → Add (available once the Cursor Marketplace listing is approved; Grok Bot uses the Cursor plugin catalog). |
| Claude Code | /plugin marketplace add StackOneHQ/stackone-plugin then /plugin install stackone@stackone. |
| Codex / ChatGPT desktop | codex plugin marketplace add StackOneHQ/stackone-plugin then codex plugin add stackone. The Plugins Directory listing follows once OpenAI review completes. |
| Any MCP client | Add https://mcp.stackone.com/mcp as a remote (Streamable HTTP) server. |
You need a StackOne account with at least one connected integration. Create one at app.stackone.com.
What it does
The server exposes four tools:
| Tool | What it does |
|---|---|
stackone_search_actions | Describe a goal in plain language and get the matching actions across every connected integration (30,000+ actions, ranked by Advanced Tool Search). |
stackone_execute_action | Run one of those actions with the arguments it returns. Write and destructive actions follow the host's approval flow. |
stackone_list_accounts | List the accounts (Workday, Salesforce, Notion, Jira, …) linked to your session and their ids. |
stackone_submit_feedback | Report a tool result that was wrong or unhelpful. |
Example prompts once connected:
- "List the accounts I have connected through StackOne."
- "Use StackOne to find my open Workday time-off requests."
- "Create a Jira issue for the bug we just discussed, via StackOne."

https://idp-api.stackone.com/api/auth. On first use your host opens the StackOne sign-in page. No API keys or secrets live in this repo. - Scopes:
mcp,offline_access(refresh tokens so you sign in once). - Network endpoints this plugin calls:
mcp.stackone.com(the MCP server) andidp-api.stackone.com(sign-in). Nothing else. - What runs locally: nothing. No hooks, no scripts, no bundled binaries. The plugin is a manifest and a server URL.
- Data: actions run against the SaaS accounts you have linked in StackOne, under the permissions of that link. Privacy policy: https://www.stackone.com/terms/privacy-policy/. Terms: https://www.stackone.com/terms/saas-terms/.
Repository layout
Each host reads its own manifest file, so the same facts appear a few times. scripts/check-manifests.py (run in CI) keeps them identical.
