Use n8n with AI via MCP
Not every system ships an MCP server of its own – n8n fills exactly that gap. Through the MCP Server Trigger, a workflow on your own n8n instance becomes a tool for AI agents. That puts n8n's more than 2,000 existing integrations within reach even where no vendor endpoint exists yet.
What is n8n?
n8n is an automation platform for connecting processes across system boundaries: a trigger starts a workflow, which calls services in sequence, processes data and writes results back. More than 2,000 integrations are available out of the box, plus generic HTTP and database building blocks for everything else. n8n can be self-hosted – a key reason for its adoption in organizations with firm requirements around data residency and operations.
For AI agents, n8n matters for two reasons. First as a bridge: systems without their own MCP server become reachable through a workflow. Second as a control point – the workflow defines exactly which action runs with which parameters, instead of granting an agent broad permissions in a third-party system.

How to Connect n8n to CompanyGPT
Since version 1.88 (April 2025), n8n ships an MCP Server Trigger node. It turns a workflow itself into an MCP server: it runs on your own n8n instance and exposes the defined actions as tools. SSE and streamable HTTP are supported, and access is secured through bearer or header authentication.
The decisive point is control over scope: every tool corresponds to a workflow you designed. An agent cannot do more than the workflow permits – “create a leave request” rather than general write access to the HR system. That makes approvals easier and keeps activity traceable in the n8n execution history.
innFactory sets up n8n as a service in its own right and, on request, operates the instance for you on an ongoing basis – from provisioning in your cloud environment through workflow development to day-to-day operation. The MCP endpoint is then registered in CompanyGPT and assigned to the relevant teams via roles and groups.
Typical Use Cases
How AI agents in CompanyGPT work with n8n
Connect systems without an MCP server
A line-of-business system with no vendor endpoint becomes reachable through an n8n workflow and is available to the assistant as a clearly bounded tool.
Trigger multi-step processes
The agent starts an approval process that the workflow drives across several systems in sequence – from validation through to notification.
Encapsulate recurring tasks
Frequent operations such as creating a ticket with standardized fields are exposed as a tool instead of being carried out by hand every time.
Frequently Asked Questions
n8n and AI – the most important answers
Is there a cloud-hosted n8n MCP server?
The MCP Server Trigger is a node that runs on your own n8n instance. The endpoint therefore belongs to your environment and is not operated by a third party.
How is access secured?
Through bearer or header authentication. In addition, the workflow itself determines which actions are possible at all – an agent can only run what you modeled.
Do we need our own n8n installation?
Yes, the trigger requires an n8n instance. innFactory sets up n8n as a service in its own right and can also take over ongoing operation including workflow development.
When is n8n the better choice than a vendor MCP server?
Whenever a system offers no MCP server of its own, or when the scope should be kept deliberately narrow. If an official endpoint with suitable permission handling exists, that one is normally used directly.
Does the data stay in our environment?
CompanyGPT and your n8n instance run in your own cloud environment. Traffic between them never leaves it; only what a workflow deliberately hands to a third-party system goes outside.
