The MCP Gateway
for Glean agents
Let your Glean agent act across 270+ enterprise SaaS — without leaving Glean. No auth hassle. Token-efficient by design. Security and governance built-in.
What is an MCP gateway?
MCP gateways are real-time integration infrastructure connecting AI
agents to the SaaS apps they need to use. They expose one MCP server
instead of many to the AI agent. They are built on the open Model Context Protocol (opens in new tab), and
are also called MCP aggregators.
MCP gateways use whatever communication protocol each MCP server requires
(stdio, SSE, streamable HTTP), maximize the action coverage agents can
call, and handle authentication, agent action scoping, tool-call
optimization, agent security, and tool-call observability.
StackOne's MCP gateway — SOC2, HIPAA, CCPA, and GDPR compliant — brings this infrastructure to 270+ pre-built SaaS integrations exposing 18,000+ actions, reachable from your Glean agent through one URL.

Frequently Asked Questions
Glean Agents act across enterprise SaaS through StackOne's MCP gateway. Setup happens in the Glean Admin Console: open Platform → Actions → Add → Import tools from MCP server, paste the StackOne gateway URL with OAuth, and import. Available immediately to every Glean Agent in your workspace, and 270+ pre-built SaaS connectors are reachable through that single connection. Full walkthrough in the Connect remote MCP servers to Glean docs. Available on Glean Enterprise; agent runs consume FlexCredits.
An MCP gateway is real-time integration infrastructure connecting AI agents to the SaaS apps they need to use. It exposes one MCP server instead of many to the AI agent, and handles authentication, agent action scoping, tool-call optimization, agent security, and tool-call observability. Also called an MCP aggregator.
Glean Agents can access enterprise SaaS like Salesforce, Workday, Stripe, Datadog, NetSuite, ServiceNow, Greenhouse, SAP SuccessFactors, and BambooHR through the StackOne MCP gateway — categories that complement Glean's 17 first-party MCP partners. 270+ pre-built connectors total. New connectors ship continuously, and you can build custom ones with AI Integration Builder. See all connectors.
Glean ships 17 first-party MCP partners (Amplitude, Asana, Atlassian Rovo, Box, Canva, ClickUp, GitHub, HubSpot, Intercom, Linear, Lucid, Monday, Notion, PagerDuty, ThoughtSpot, Udemy, WisdomAI). StackOne adds the other 270+ — every app reachable through one MCP server import instead of 17+ separate ones, auth managed once in the dashboard, and tool definitions loaded only when relevant to the prompt.
Credentials sit at three layers: the StackOne MCP server record (OAuth in Glean Admin Console → Platform → Actions, controlled by Glean platform admins), SaaS connector credentials (server-side in your StackOne dashboard), and per-user OAuth or session tokens (server-side, scoped per user). StackOne stores OAuth tokens and API keys, refreshes them automatically, and only exposes the actions you've authorized to the agent.
Skip the StackOne MCP gateway when any of these is true:
- Glean's 17 first-party MCP partners (Amplitude, Asana, Atlassian Rovo, Box, Canva, ClickUp, GitHub, HubSpot, Intercom, Linear, Lucid, Monday, Notion, PagerDuty, ThoughtSpot, Udemy, WisdomAI) already cover your apps
- You only use a handful of actions across a few apps
- You don't need multi-tenancy, per-user permissions, or per-action scoping
- Indirect prompt injection isn't a concern
- Your MCP provider already does tool discovery and server-side execution to keep the agent context lean
