StackQL MCP Server
官方使用SQL將雲端供應商的控制平面和資料平面暴露給代理，作為自我描述、可查詢且可變的資料來源，從而最小化工具表面和令牌使用量。
你可以用 StackQL MCP 做什麼？
- 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.
文件
These are the tools exposed by the StackQL MCP server. Availability of mutation and lifecycle tools depends on the server mode (
