metabase-mcp-agents (nchgn/metabase-mcp-agents) is an MCP server listed on the M8ven Trust Index. M8ven has not graded it: we have no way to read this server ourselves. No publisher has claimed this listing.
MCP server for Metabase that gives AI agents full access to query, explore, and manage content in your Metabase instance.
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.

METABASE_API_KEY"": "mb_...",METABASE_DATABASE_IDNo Default database ID for queries (default: 2)METABASE_ENV_FILE"": "/path/to/.env"METABASE_URL"": "https://your-metabase.example.com",Tool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
16/16 tools missing one or more hints — query (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); export (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); run_card (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +13 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.
Tool inputs are validated
12/16 tool handlers declare input schemas (75%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 0/16 tool handlers wrap calls in try/catch (0%)
Wrap each tool handler body in try/catch and return a structured error response.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tests exist
No test files found
Add tests that exercise each declared tool.
Secrets stay with their owner
2 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.
