Control the tools in the client
Review the discovered tool list and disable tools the task does not need. Write annotations and approval prompts help distinguish an inspection from a change, even though the current Clerk grant is not split into custom training scopes.
Check the data shape
A trustworthy connection says whether it exposes raw samples, aggregates or summaries. Bulk Coach excludes Apple Health from its external MCP tool catalogue.
Test revocation
Disconnect the client and confirm that a later request fails. Revocation is part of the feature, not an account-support exception.
