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.
list_tablesList all user tables in the public schema
describe_tableShow column names, data types, nullability and defaults for a table
select_rowsSELECT rows from a table with an optional WHERE clause and row limit
insert_rowINSERT a single row into a table and return the inserted record
update_rowsUPDATE rows matching a WHERE clause and return affected records
delete_rowsDELETE rows matching a WHERE clause and return the deleted records
audit_account_wasteAudit the entire ad account for wasted spend. Scans all entities (keywords, audiences, creatives, ad groups) across all campaigns over the last N days. Flags any entity whose spend exceeds a threshold while generating zero (or near-zero) conversions, or whose CPA is far above the account average. …
get_waste_detailGet a detailed daily breakdown for a single ad entity (keyword, audience, creative, ad group). Use after audit_account_waste to drill into why a specific entity was flagged — shows day-by-day spend, clicks, impressions and conversions, plus the parent campaign info. Args: - entity_id (number): T…
simulate_reallocationSimulate the budget impact of pausing one or more entities, WITHOUT making any changes. Calculates how much daily/monthly spend would be freed up if the given entities were paused, based on their average daily spend over the last N days. Use this BEFORE calling pause_entity to show the projected im…
pause_entityPause a specific ad entity (keyword, audience, creative, or ad group). ⚠️ ACTION TOOL: this changes the status of the entity to 'paused'. Always run simulate_reallocation first and confirm with the user before calling this, unless the user has explicitly asked you to proceed. A reason is required …
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default
DATABASE_URLTool 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_tables (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); describe_table (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); select_rows (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.
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, 3 high severity in production deps — @modelcontextprotocol/sdk@1.10.0 (high), @modelcontextprotocol/sdk@1.10.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
