MCP server for SAP Datasphere that enables AI assistants to perform data discovery, metadata exploration, analytics queries, ETL data extraction, database user management, and data profiling with built-in PII masking.
Emerging. No concerning findings. Grades remain capped until the project builds reputation through adoption. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

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
56/56 tools missing one or more hints — handle_call_tool (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_spaces (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_space_info (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +53 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 1/56 tools referenced in tests (2%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
5 child_process/subprocess calls in production code — runs shell commands (bin/sap-datasphere-mcp.js:17, bin/sap-datasphere-mcp.js:19, bin/sap-datasphere-mcp.js:47)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Secrets not logged
12 secret values sent to console.log
Redact or omit secret values from log output.
No arbitrary install scripts
Has postinstall/preinstall script — runs arbitrary code on npm install
Remove postinstall/preinstall hooks unless they’re essential.
Domain consistency
npm scope @mariodefe doesn't match GitHub owner nicolasventuriniflexso
Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.
