You can create and configure custom MCP (Model Context Protocol) servers to extend Notis capabilities with your own tools and integrations inside the portal.
This page is for adding another MCP server to Notis. To add Notis to ChatGPT, Claude, Grok, Notion, or a coding agent, follow Connect an agent.
Custom MCPs are available across the main channels and inside your agents. image.png

​
When to use a custom MCP

Reach for an MCP server when:
  • The tool you need is not part of the Composio integration catalog.
  • You want to expose an internal service, database, or proprietary API to Notis.
  • A vendor publishes an official MCP server you’d like to plug straight in.
If the MCP server needs to run on your own computer — your files, a local CLI, or a service on localhost — use Local MCP instead. This page covers MCPs that Notis reaches over the public internet.

​
Adding an MCP server

  1. Open Integrations in the sidebar (under Customize) and click Add MCP.
  2. Display Name: a name you’ll recognize, such as the service’s name.
  3. Description: a few words on what the server does. It shows on the server’s card.
  4. Server URL: paste the server’s address.
  5. Authentication: choose how the server knows it’s you.
    • None if the server needs no sign-in or key.
    • Headers if the service gives you an access key: usually an Authorization header with the value Bearer followed by your key.
    • OAuth if you sign in with an account and the server supports it: click Connect and sign in on the page that opens. Notis saves the server when you come back.
  6. With None or Headers, click Save. Notis connects the server and loads its tools. If that fails, for example because the key is wrong, nothing is saved and Notis shows why.
Every tool the server offers is then available to Notis in every channel. To load a saved server’s tools again, open it and click Test. Each guide that uses an MCP server lists the exact values to enter for that service. You can also set this up straight from a conversation: tell Notis the server address and the access key it should use, and it saves the connection for you, no need to open the portal. Once added, MCP tools behave like any other Notis integration: ask in chat, voice, or from a coding agent and Notis will pick the right tool for the job.

​
When a server needs attention

If a server’s card shows a problem, click that status. Reconnect opens the sign-in again. Any other problem, such as Couldn’t connect, opens the server’s settings so you can check its address and access details.

​
Not supported yet

Notis shows Not supported yet for a server when:
  • its address does not start with https://,
  • it needs more than one access key,
  • its sign-in page does not let apps like Notis set themselves up. Many of these servers also accept an access key: use that instead.
