The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
listTablesGet a list of all tables in the database along with their column information. Use this first to understand the database structure before querying.
ExecuteSelectQueryTableExecute a SELECT query against the table in the PostgreSQL database.
GetRequiredFieldsTableGet the required fields of a table in the PostgreSQL database.
InsertDataOnTableInsert data on a table in the PostgreSQL database.
UpdateDataOnTableUpdate data on a table in the PostgreSQL database.
RemoveDataOnTableRemove data on a table in the PostgreSQL database.
SaveQueryDatabaseSave SQL query to run later.
ExecuteSavedQueryDatabaseListSavedQueriesDatabaseDisclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

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
9/9 tools missing one or more hints — listTables (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); ExecuteSelectQueryTable (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); GetRequiredFieldsTable (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.
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.
Production dependencies are patched
0 critical, 14 high severity in production deps — @modelcontextprotocol/sdk@1.13.1 (high), @modelcontextprotocol/sdk@1.13.1 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
2 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
Dependency freshness
1/14 production deps stale: just-pick@2023-07-12 (3.1y)

Add it once and ask Claude, ChatGPT, or any MCP client to grade a server, surface CVEs, check the publisher, and suggest safer alternatives — before you install.
