16 tools. 9 can modify or destroy data without limits.
1 destructive tool with no built-in limits. Policy required.
Last updated:
Destructive tools (delete_dashboard) permanently delete resources. There is no undo. An agent calling these in a retry loop causes irreversible damage.
Write operations (add_card_to_dashboard, create_card, create_collection) modify state. Without rate limits, an agent can make hundreds of changes in seconds — faster than any human can review or revert.
Execute tools (execute_card, execute_query) trigger processes with side effects. Builds, notifications, workflows — all fired without throttling.
Intercept sits between your agent and Metabase Analytics Integration Server. Every tool call checked against your policy before it executes — so your agent can do its job without breaking things.
npx -y @policylayer/intercept scan -- npx -y @ryanmaule/metabase-mcp delete_dashboard:
rules:
- action: deny Destructive tools should never be available to autonomous agents without human approval.
add_card_to_dashboard:
rules:
- rate_limit: 30/hour Prevents bulk unintended modifications from agents caught in loops.
get_dashboard_cards:
rules:
- rate_limit: 60/minute Controls API costs and prevents retry loops from exhausting upstream rate limits.
Yes. The Metabase Analytics Integration Server server exposes 1 destructive tools including delete_dashboard. These permanently remove resources with no undo. Intercept blocks destructive tools by default so they never reach the upstream server.
The Metabase Analytics Integration Server server has 6 write tools including add_card_to_dashboard, create_card, create_collection. 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.
16 tools across 4 categories: Destructive, Execute, Read, Write. 7 are read-only. 9 can modify, create, or delete data.
One line change. Instead of running the Metabase Analytics Integration Server server directly, prefix it with Intercept: intercept -c ryanmaule-metabase-mcp.yaml -- npx -y @ryanmaule/metabase-mcp. Download a pre-built policy from policylayer.com/policies/ryanmaule-metabase-mcp and adjust the limits to match your use case.
Starter policies available for each. Same risk classification, same one-command setup.
