Write-enabled MCP server for Metabase with 28 tools covering read, write, and AI-driven insights operations.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

30/30 tools missing one or more hints — batch_execute (missing: readOnlyHint, destructiveHint, idempotentHint); ask_data (missing: destructiveHint, idempotentHint); generate_insights (missing: destructiveHint, idempotentHint), +27 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Secrets stay with their owner
3 secret/sensitive values flow into network calls (METABASE_API_KEY → dynamic, METABASE_API_KEY → dynamic)
Audit where credentials are sent. A NOTION_TOKEN should only reach api.notion.com — never a third-party host.
Secrets not logged
6 secret values sent to console.log
Redact or omit secret values from log output.
