What can you do with StackQL MCP?

  • Discover cloud resources — Ask which providers, services, and resources are available in the local StackQL cache via list_providers, list_services, and list_resources.
  • Inspect API contracts — Get the full input/output schema for any resource method using describe_method before writing queries.
  • Validate and run queries — Check a SELECT statement without executing it via validate_select_query, then run it with run_select_query.
  • Manage providers — See available registry versions and install a provider into the local cache using list_registry and pull_provider.
  • Execute mutations — Run INSERT, UPDATE, REPLACE, or DELETE operations against a provider with run_mutation_query.
  • Trigger lifecycle ops — Execute StackQL EXEC lifecycle operations (e.g., start/stop instances) via run_lifecycle_operation.
