The Apps tab on the Connectors page connects tools your team already uses. Unlike the Data tab, connecting an app doesn’t create datasets. It lets Addison call that app directly while you chat.
The Apps tab of the Connectors page, selected alongside a Data tab, with an Add custom app button top-right and a search field. Available apps are grouped by category: AI with Exa ('Search and extract structured content from across the internet with Exa.'), and Analytics with Domo ('Connect to Domo analytics, datasets, dashboards, and business intelligence workflows.'), PostHog ('Analyze PostHog events, product analytics, feature flags, experiments, and sessions.'), and Tableau ('Access Tableau sites, projects, workbooks, views, and analytics assets.'). Each card has an icon, a description, and a + button to connect.

Available apps, by category

​
Available apps

Apps are grouped by category on the tab. What’s listed today: GitHub appears here as its own entry, separate from the GitHub connector on the Data tab: this one lets Addison work with issues and pull requests in a chat, while the Data tab one brings a repository in as a dataset. New apps are added regularly. If the one you need isn’t listed, see Custom apps below.

​

Review and connect

A dialog explains what access you’re granting. Select Connect. Most apps hand off to that provider’s own sign-in to authorize access.
A connect dialog for Shopify headed 'Give Summation access to your Shopify connector', listing three points: 'Use Shopify in Addison — Manage Shopify products, orders, customers, inventory, and commerce workflows', 'Your data stays yours — Summation does not train models on your connector content. Addison uses this connection only to answer your requests', and 'You control access — Disconnect anytime from MCP settings'. A note reads 'Third-party connectors are not built or maintained by Summation. Review the permissions before connecting. Usage is subject to the Summation Privacy Policy.' above a Connect button.

Turn it on for a chat

Connecting an app isn’t enough on its own. In the chat composer, open the + menu, then App connectors, and toggle the app on for that conversation. Only connectors with Active status are listed.
The chat composer's + menu open, showing Upload Files, Add files from project, and App connectors (highlighted, with a submenu arrow). Its submenu lists Gmail with an enabled toggle switch, and an Add new connector option below it.

Enabling a connected app from the composer

Once an app is enabled, ask Addison to read from it and turn what it finds into lasting context: “Summarize our latest Gmail thread with Acme Corp into a guide,” or “Read our Shopify orders and define gross margin as a metric.”

​
Custom apps

If the app you need isn’t in the catalog:
  • Request an app tells us what to add.
  • Add custom app (top-right of the Apps tab) connects any app that exposes its own MCP server directly.
An 'Add custom app' dialog reading 'Connect an HTTPS Streamable HTTP MCP server. We will detect sign-in requirements and verify the tools Addison can use.' with a Name field ('Shown in the connectors list') and a Remote MCP server URL field ('The HTTPS address where the server accepts MCP requests, for example https://mcp.example.com/mcp. Sign-in is detected automatically. Most servers do not need any additional setup.'), a collapsed 'Advanced OAuth settings' section, a warning 'Only use connectors from developers you trust. Summation doesn't control or verify third-party connectors. They may not work as intended, and they can change without notice.', and Cancel / Connect buttons.

Adding a custom app by its MCP server URL

Sign-in is detected automatically for most servers. Summation figures out whether the server needs OAuth and walks you through it. Only add servers from developers you trust: Summation doesn’t build, control, or verify third-party MCP servers, so they may not work as intended and can change without notice.

​
Manage connected apps

Connected apps move to a Connected section at the top of the Apps tab, where you can View Connector Details or Disconnect.
Third-party apps aren’t built or maintained by Summation, so review the permissions before connecting. Summation doesn’t train models on your connector content, and you can disconnect at any time.

Common problems

Apps are a different feature from Applications (also called SumApps), the purpose-built tools listed under Applications in the left nav. Apps connect third-party tools into a chat; Applications are standalone tools built for your workspace.
