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.
load_csvLoad a CSV file into DuckDB for analysis
query_csvExecute SQL query on loaded CSV data
describe_tableGet schema information for a loaded table
list_tablesList all loaded tables
analyze_csvPerform basic statistical analysis on CSV data
load_multiple_csvsLoad multiple CSV files using glob patterns or file lists into DuckDB for analysis
discover_csv_filesDiscover CSV files matching a glob pattern
optimize_expensesAnalyze credit card spending data to identify expense optimization opportunities with actionable recommendations and savings estimates
detect_anomaliesDetect anomalies and irregularities in dataset using statistical analysis and business logic rules
load_excelLoad an Excel (.xlsx) file into DuckDB for analysis
load_multiple_excelsLoad multiple Excel files using glob patterns or file lists into DuckDB for analysis
discover_excel_filesDiscover Excel files matching a glob pattern
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
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
12/12 tools missing one or more hints — load_csv (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); query_csv (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); describe_table (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +9 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
4/12 tools referenced in tests (33%)
Write tests that reference each tool by name so every tool has at least one test.
Production dependencies are patched
0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.17.2 (high), @modelcontextprotocol/sdk@1.17.2 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
