Microsoft 365 Copilot connectors library
Synced Graph connectors and federated MCP connectors from the Microsoft Learn gallery tables, labeled by how each one connects.
There is no public searchable catalog of Copilot connectors. The public sources are Microsoft Learn gallery tables, and the in-product gallery requires Microsoft 365 admin sign-in. This page lists 118 named entries from those tables, researched October 29, 2026, each labeled synced or federated. It is not a census: table rows include variants of the same system, and counts from different universes must not be mixed.

01 - How connections work
The label on each entry below comes from this list.
Content is crawled and indexed into Microsoft Graph, with semantic indexing, so Copilot, Copilot Search, and Microsoft Search can ground answers in it. The connector runs under a service account identity and is tenant-wide unless external-item security restricts it. Synced connectors read and search. They are built with the connector APIs, the connector SDK, or the Microsoft 365 Agents Toolkit, with Entra app registration and admin consent.
Queries run in real time over MCP at prompt time. Nothing is indexed into Microsoft 365 and data stays at the source. Copilot acts under the user’s own identity and permissions, so it only sees what the user may see. Federated connectors read, and create, update, and delete where the connector provides the tools, with user approval. The Researcher agent is read-only. Write-action support was reported as rolling out in October 2026, and is not presented here as uniformly available.
Open the Microsoft 365 admin center and go to Copilot, then Connectors, then the Gallery tab. That gallery needs admin sign-in and could not be verified live for this page. The public Microsoft Learn gallery tables are documentation, not the live gallery: entries may be in preview, retired, or region-gated without the page saying so. A user sees a federated connector only when five conditions all hold: the publisher type is allowed or the connector is individually enabled, the connector is enabled, the user is in the User access population, the user is in the staged rollout, and the user holds a Microsoft 365 Copilot licence.
Public sources for the tables behind this page: the Microsoft-built gallery, the partner-built gallery, and the federated connectors overview on Microsoft Learn.
02 - The library
118 of 118 connectors. Statuses: Synced means content is indexed into Microsoft Graph, Federated means real-time over MCP with no indexing, Synced + Federated means both variants are listed, Partner built means a partner publisher variant in the partner gallery.
About these links: each name links to the company behind the connector, usually its main website. Cask & Hound does not control those sites, and a listing here is not an endorsement or a guarantee the connector is available in your tenant. Three entries carry no link: two are generic connector types with no vendor, and one names a vendor whose company site could not be confirmed. Links were last checked October 29, 2026.

03 - Beyond the gallery tables
What to know before mixing counts that belong to different universes.
Power Platform connectors are prebuilt wrappers around APIs for Power Apps, Power Automate, Logic Apps, and Copilot Studio, with standard and premium tiers. Microsoft Learn training states more than 1,800 prebuilt connectors, and the certification overview states over 1,200 connectors launched to date. Those counts describe the Power Platform catalogue, not Copilot connectors. The overlap is only the subset usable as Copilot Studio tools or knowledge, or certified as Copilot plugins. Never add the counts together.
Copilot Studio agents use knowledge sources, tools and actions, and triggers. Knowledge sources include SharePoint, OneDrive, documents, public websites, Graph connectors, and, in preview, Power Platform connectors as real-time knowledge. Teams app packages can carry declarative agents, API plugins, and message extensions. API plugins work only as actions within declarative agents, not in Microsoft 365 Copilot itself. Publishing for ISVs goes through the Microsoft 365 and Copilot program in Partner Center.
Federated connectors can be Microsoft-published or submitted by partners to Microsoft for approval and publication in the Connectors Gallery, using a single connector manifest and a single publishing pipeline. No step-by-step public submission checklist, fee, or SLA was found in the Learn pages read. Teams and 365 apps go through Partner Center with validation guidelines. Power Platform connectors go through certification: the ConnectorPackageValidator script, automated validation, then manual review and testing by Microsoft engineers. Certification is free. In-tenant custom connectors need no Microsoft review: the tenant admin vets and publishes.
Counts, kept apart: Microsoft Learn claims more than 100 prebuilt connectors, the only official total. The researcher’s own counts of the Learn tables were about 255 Microsoft-built rows and about 150 partner-built rows, and about 178 names in the federated overview table. Rows are not unique systems: the same system appears more than once, as synced and federated variants, cloud and server editions, or from multiple publishers. Only three partner-built entries are flagged Certified for Microsoft 365 Copilot. Federated general availability on September 23, 2026, is reported from a secondary source citing Roadmap 501120; the Learn overview page itself carries no GA date. Write actions for federated connectors are described in Learn as possible where tools provide them, with user approval, but a secondary October roundup described write support as still rolling out, so write support is not presented here as uniformly available. No general regional restriction list was found in the Learn connector pages read. The Researcher agent is read-only. Windows and Edge Copilot surfaces share the federated and MCP pattern only loosely and are not the admin-center connector system, so they are out of scope for this page.
04 - Questions
Straight answers on the catalog that does not exist, the licence, and what certified means.
No, not as a public storefront. What exists publicly are Microsoft Learn documentation tables: a Microsoft-built gallery, a partner-built gallery, and a federated overview. The in-product gallery lives in the Microsoft 365 admin center behind admin sign-in, and could not be verified live. This page is curated from the Learn tables, not exhaustive.
Synced connectors copy content into Microsoft Graph by crawling and indexing it, under a service-account identity, for search and grounding. Federated connectors query the source live over MCP at prompt time, index nothing, and act under the user’s own identity and permissions. Federated connectors can also write where their tools provide it, with user approval, except in the Researcher agent, which is read-only.
Yes. End users need a Microsoft 365 Copilot licence, which is an add-on requiring a qualifying Microsoft 365 or Office 365 base plan. Configuring and deploying needs the AI administrator role in the admin center, plus admin access to the external service. Each connector also needs the user’s own account and permissions in the source system.
Only three partner-built entries in the partner gallery are flagged Certified for Microsoft 365 Copilot: Box, CB Insights, and getAbstract. Microsoft-built gallery entries are supported by Microsoft, which is a different statement. Do not call every gallery entry certified.
No. Power Platform connectors are a separate universe: prebuilt wrappers around APIs for Power Apps, Power Automate, Logic Apps, and Copilot Studio. Microsoft Learn training states more than 1,800 prebuilt connectors, and the certification overview states over 1,200 connectors launched to date. Those counts describe the Power Platform catalogue, not Copilot connectors. The overlap is only the subset usable as Copilot Studio tools or knowledge, or certified as Copilot plugins.
Yes. We build the MCP server or Graph connector surface, prepare Partner Center certification or gallery submission, and test it end to end. Start with a conversation about what your users would ask Copilot to do with your product.
We connect teams to the services above, and we build MCP servers, Graph connectors, and certification submissions for products that should be reachable from an agent. First call is about your goals and whether we are a fit.
