Connect n8n or your own code over MCP
In n8n, add an MCP Client node, choose HTTP Streamable transport and the URL https://mcp.xgenplus.com/mcp, and use header auth with name Authorization and value Bearer <TOKEN>. In your own code, connect with any MCP SDK's Streamable HTTP client and send the same header. Give automations narrow permissions, because nobody watches each step.
How to connect an automation
- Create an agent password with only the permissions the automation needs, and make your token.
- In n8n: add an MCP Client node, set the transport to HTTP Streamable and the URL to
https://mcp.xgenplus.com/mcp. - Set authentication to header auth, with name
Authorizationand valueBearer <TOKEN>, saved as an n8n credential. - In your own code: connect with the MCP SDK's Streamable HTTP client and the same header.
When to use it
Rohit builds an n8n workflow that runs every evening, lists the day's unread supplier mail and posts a summary to his team. Its agent password has only List folders, Search email and Read email.
Python example
import asyncio, os
from mcp import ClientSession
from mcp.client.streamable_http import streamablehttp_client
async def main():
headers = {"Authorization": "Bearer " + os.environ["XGENPLUS_TOKEN"]}
async with streamablehttp_client("https://mcp.xgenplus.com/mcp", headers=headers) as (read, write, _):
async with ClientSession(read, write) as session:
await session.initialize()
result = await session.call_tool("get_inbox_summary", {})
print(result.content)
asyncio.run(main())
Good to know
- Mail content is untrusted. Automations act without a person watching. Never let mail content decide where mail is sent.
- Keep the token in your automation tool's credential store or an environment variable, never in code.
- Respect the limits. A
RATE_LIMITEDerror says when to retry. - Pass the same
idempotency_keywhen you retry a send, so it is not sent twice.
Common questions
Can an automation send mail on its own?
Only if you turn on Send email for its agent password. Risky sends, such as to a first-time external recipient, are still held as drafts for review.
