// key findings
⚠️
Known vulnerabilities in dependencies: 3 high
Affects packages this MCP installs at runtime. Upgrade or remove the affected dependency.
✅
No credential exfiltration, no sensitive file access, no obfuscation
Static analysis found nothing flowing your secrets to unexpected places.
✅
Open source with a license and README
Anyone can audit the code, the license is declared, and the publisher documents what it does.
// tools this server exposes13 tools

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.

list_databases

List configured database aliases. Use the returned names in the "database" parameter of other tools.

list_schemas

List all schemas in the database.

list_objects

List tables, views, sequences, or extensions in a schema.

get_object_details

Get columns, constraints, and indexes for a table or view.

execute_sql

Execute any SQL statement (unrestricted mode — development only).

explain_query

Get the query execution plan. Supports hypothetical index simulation (requires hypopg extension).

get_top_queries

Report the slowest or most resource-intensive queries using pg_stat_statements.

analyze_db_health

Run comprehensive database health checks across multiple dimensions.

analyze_workload_indexes

Analyze query workload from pg_stat_statements and recommend missing indexes.

analyze_query_indexes

Analyze specific SQL queries and identify missing indexes. Maximum 10 queries.

detect_index_misses

Detect tables likely suffering from missing indexes: seq-scan dominance, FK columns without indexes, under-indexed hot tables.

analyze_locks

Detect lock contention: blocking chains, long-running queries, idle-in-transaction sessions.

analyze_table_bloat

Detect table and index bloat from dead tuples. Returns vacuum recommendations.

// known CVEs in dependencies3 high

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

14/14 tools missing one or more hints — list_databases (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_schemas (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_objects (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +11 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

9/14 tool handlers declare input schemas (64%)

Declare an inputSchema with zod/joi/yup on every tool definition.

Tool handlers catch errors

13/14 tool handlers wrap calls in try/catch (93%)

Wrap each tool handler body in try/catch and return a structured error response.

Tests exist

No test files found

Add tests that exercise each declared tool.

Production dependencies are patched

0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.12.0 (high), @modelcontextprotocol/sdk@1.12.0 (high)

Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 6 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
