StackQL MCP Server
公式クラウドプロバイダーのコントロールプレーンとデータプレーンを、SQLを使用して自己記述的でクエリ可能かつ変更可能なデータソースとしてエージェントに公開し、ツールの表面積とトークン使用量を最小化します。
StackQL MCPで何ができますか？
- Explore provider catalogs — List cached providers, their services, resources, and access methods to find what can be queried.
- Inspect method contracts — Describe a single access method's inputs and output fields before writing a query.
- Manage the registry — List available providers and versions in the registry, then pull a provider into the local cache.
- Find and render query templates — Search the query library by intent, provider, service, or tags, then validate parameters to render SQL without executing it.
- Validate and run SELECTs — Parse and plan a SELECT without executing it, or run it against a provider.
- Run mutations and lifecycle operations — Execute INSERT, UPDATE, REPLACE, or DELETE, or an EXEC lifecycle operation, subject to the server mode.
