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.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
fast-xml-parser has an entity encoding bypass via regex injection in DOCTYPE entity names
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default
fast-xml-parser has RangeError DoS Numeric Entities Bug
fast-xml-parser affected by numeric entity expansion bypassing all entity expansion limits (incomplete fix for CVE-2026-26278)
fast-xml-parser affected by DoS through entity expansion in DOCTYPE (no expansion limit)

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 — odata_config (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); odata_list_entities (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); odata_metadata (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.
Tool test coverage
Only 2/9 tools referenced in tests (22%)
Write tests that reference each tool by name so every tool has at least one test.
Production dependencies are patched
1 critical, 4 high severity in production deps — fast-xml-parser@5.2.5 (critical), @modelcontextprotocol/sdk@1.0.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

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.
