Universal Database (anarkh-lee/universal-db-mcp) 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.
Provides unified database connectivity across PostgreSQL, MySQL, Oracle, Redis, and 13 additional databases with standardized operations for structured queries and key-value storage.
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.

Install from
M8ven verifies MCPs across every public registry — install directly from whichever one you prefer.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

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
9/9 tools missing one or more hints — execute_query (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_schema (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_table_info (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +6 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 test coverage
Only 0/9 tools referenced in tests (0%)
Write tests that reference each tool by name so every tool has at least one test.
Production dependencies are patched
0 critical, 2 high severity in production deps — fastify@4.29.1 (high), nanoid@5.1.6 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
1 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
