Toolkit Reference

Choose a toolkit

Select a provider by capability coverage, account model, and operational constraints.

Start with the capability, then compare only the providers that implement the required canonical actions.

Then check:

  1. Does the generated tool table contain every action in your workflow?
  2. Can your deployment provide the listed auth type and scopes?
  3. Do you need a declared x_provider extension?
  4. Is the tool read-only, mutating, destructive, or async?
  5. Does the mock cover the success and failure cases you will ship?
