SQL Explorer is built around a small set of plugin types. Providers add databases, tools run operations, MCP servers open data to AI, and extensions stand up whole subsystems. Each loads at runtime, in isolation.
Everything below is first-party — shipped and supported by the SQL Explorer team, not third parties. Third-party plugins install exactly the same way, and anyone can build and distribute their own with the SDK.
Drop a folder into plugins/ next to the app with a plugin.json manifest and an entry assembly built against SqlExplorer.Sdk. The host discovers it on start.
{ "schemaVersion": 1, "id": "my-engine", "type": "provider", // provider | tool | mcp | extension "name": "My Engine", "version": "1.0.0", "hostApiVersion": 26, "entryAssembly": "MyEngine.Provider.dll" }
Install SQL Explorer and start with the bundled providers — add more whenever you need.
