[Watch on YouTube](https://www.youtube.com/watch?v=0WAOtNaKjws) · Microsoft Dynamics 365 Business Central (YouTube) · 2026-04-01 · 18:02 · tier official · reviewed (checked by Opus) ## Overview The session covers what changed in the Business Central MCP server in 2026 release wave 1. It starts with configuration validation, which warns when APIs or queries in an MCP configuration are removed, for example when an app is uninstalled, and offers recommended actions. It then covers exporting a configuration to JSON and importing it into another environment. It also covers connecting other MCP hosts, a connection string under advanced settings, telemetry and audit logging of configuration changes, and MCP resources. Embedded resources let the server return large data as file references instead of text, so the host can pass them to a code execution tool. Demos show the connection string and embedded resources. ## Key points - Configuration validation checks whether an MCP configuration is still valid after APIs or queries are added or removed, warns when parent APIs are missing (for example api sales header for api sales line), and offers automatic recommended actions. - A configuration can be exported to JSON in one environment and imported into another, which supports moving it across test, pre-production and production. - Microsoft Copilot Studio is the fully supported MCP host. Other hosts such as VS Code are in public preview. VS Code is pre-authorized, and other hosts may need extra setup such as an application registration. - A connection string under advanced settings gives the exact configuration needed to connect MCP clients such as VS Code to Business Central. - MCP configuration changes are logged as auditable events in Microsoft audit logs. Telemetry covers successful and failed MCP calls. MCP host type logging may be limited where HTTP headers cannot be fully trusted. - With embedded resources, list tools that return a lot of data return an embedded file reference instead of a text content block. Code execution runs on the MCP host side and needs the code interpreter enabled. - Resources are optional, and existing MCP implementations continue to work without changes. ## Chapters - [0:00](https://www.youtube.com/watch?v=0WAOtNaKjws&t=0s) Introduction to MCP Server - [1:03](https://www.youtube.com/watch?v=0WAOtNaKjws&t=63s) MCP Configuration Validations - [2:44](https://www.youtube.com/watch?v=0WAOtNaKjws&t=164s) Import Export and Multiple MCP Hosts - [4:00](https://www.youtube.com/watch?v=0WAOtNaKjws&t=240s) Connection String Demo - [5:07](https://www.youtube.com/watch?v=0WAOtNaKjws&t=307s) Telemetry and Auditing - [7:11](https://www.youtube.com/watch?v=0WAOtNaKjws&t=431s) MCP Resources Support - [9:49](https://www.youtube.com/watch?v=0WAOtNaKjws&t=589s) Embedded Resources Demo - [11:42](https://www.youtube.com/watch?v=0WAOtNaKjws&t=702s) Documentation and Related Sessions - [13:33](https://www.youtube.com/watch?v=0WAOtNaKjws&t=813s) General Business Central Resources ## Features | Feature | Status | At | Evidence | |---|---|---|---| | MCP Configuration Validations | status not stated | [1:15](https://www.youtube.com/watch?v=0WAOtNaKjws&t=75s) | | | Configuration Import Export | status not stated | [2:44](https://www.youtube.com/watch?v=0WAOtNaKjws&t=164s) | | | Support for Multiple MCP Hosts | preview, demoed | [3:22](https://www.youtube.com/watch?v=0WAOtNaKjws&t=202s) | "Other hosts would be in public preview and not kind of fully supported" ([3:22](https://www.youtube.com/watch?v=0WAOtNaKjws&t=202s)) | | Connection String Setup | status not stated, demoed | [4:29](https://www.youtube.com/watch?v=0WAOtNaKjws&t=269s) | | | MCP Configuration Telemetry | status not stated | [5:22](https://www.youtube.com/watch?v=0WAOtNaKjws&t=322s) | | | MCP Resources Support | status not stated, demoed | [7:23](https://www.youtube.com/watch?v=0WAOtNaKjws&t=443s) | | | Embedded Resources | status not stated, demoed | [7:57](https://www.youtube.com/watch?v=0WAOtNaKjws&t=477s) | | ## AL objects mentioned As heard in the captions.
