39 tools. 19 can modify or destroy data without limits.
11 destructive tools with no built-in limits. Policy required.
Last updated:
Destructive tools (bulk_delete_by_criteria, delete_datastore, delete_image_set) permanently delete resources. There is no undo. An agent calling these in a retry loop causes irreversible damage.
Write operations (bulk_update_patient_metadata, copy_image_set, create_datastore) modify state. Without rate limits, an agent can make hundreds of changes in seconds — faster than any human can review or revert.
Execute tools (start_dicom_export_job, start_dicom_import_job) trigger processes with side effects. Builds, notifications, workflows — all fired without throttling.
bulk_delete_by_criteria:
rules:
- action: deny Destructive tools should never be available to autonomous agents without human approval.
bulk_update_patient_metadata:
rules:
- rate_limit: 30/hour Prevents bulk unintended modifications from agents caught in loops.
get_datastore:
rules:
- rate_limit: 60/minute Controls API costs and prevents retry loops from exhausting upstream rate limits.
Yes. The AWS HealthImaging MCP Server server exposes 11 destructive tools including bulk_delete_by_criteria, delete_datastore, delete_image_set. These permanently remove resources with no undo. Intercept blocks destructive tools by default so they never reach the upstream server.
The AWS HealthImaging MCP Server server has 6 write tools including bulk_update_patient_metadata, copy_image_set, create_datastore. Set rate limits in your policy file -- for example, rate_limit: 10/hour prevents an agent from making more than 10 modifications per hour. Intercept enforces this at the transport layer.
39 tools across 4 categories: Destructive, Execute, Read, Write. 20 are read-only. 19 can modify, create, or delete data.
One line change. Instead of running the AWS HealthImaging MCP Server server directly, prefix it with Intercept: intercept -c aws-healthimaging-mcp-server.yaml -- npx -y @awslabs.healthimaging-mcp-server. Download a pre-built policy from policylayer.com/policies/aws-healthimaging-mcp-server and adjust the limits to match your use case.
Starter policies available for each. Same risk classification, same one-command setup.
