MCP Servers
for Notion AI Agents
Let your Notion AI Agent act across 270+ enterprise SaaS — without leaving Notion. 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 Notion AI Agent through one URL.

Frequently Asked Questions
Notion AI Agents act across enterprise SaaS through StackOne's MCP gateway. Setup takes a few clicks: open Settings → Notion AI → AI connectors, enable Custom MCP servers, click Add connection → Custom MCP server, paste the StackOne gateway URL with your account ID and token, and save. Available immediately to every AI Agent in your workspace and 270+ pre-built SaaS connectors are reachable through that single connection. Full walkthrough in the Notion AI Agents docs. Requires a Notion Business or Enterprise workspace.
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.
Notion can access enterprise SaaS like Salesforce, Workday, HubSpot, Greenhouse, Zendesk, NetSuite, ServiceNow, Stripe, and Notion through the StackOne MCP gateway — 270+ pre-built connectors in total. New connectors ship continuously, and you can build custom ones with AI Integration Builder. See all connectors.
Notion AI Agents ship with a handful of first-party MCP partners (Linear, Attio, Stripe, HubSpot, Intercom, Ramp, GitHub, Amplitude, Sentry). StackOne adds the other 270+ — every app reachable through one Custom MCP connection instead of N separate ones, auth managed once in the dashboard, and tool definitions loaded only when relevant to the prompt.
Credentials sit at three layers: your StackOne API token (embedded in the gateway URL stored in your Notion workspace settings, controlled by workspace 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:
- Notion's first-party MCP partners (Linear, Attio, Stripe, HubSpot, Intercom, Ramp, GitHub, Amplitude, Sentry) 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
