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.
@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

12/12 tools missing one or more hints — person_companies (missing: destructiveHint, idempotentHint); get_owners (missing: destructiveHint, idempotentHint); get_dd_report (missing: destructiveHint, idempotentHint), +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
Only 3/12 tools referenced in tests (25%)
Write tests that reference each tool by name so every tool has at least one test.
Secrets stay with their owner
1 secret sent to a request target we could not resolve (MCP_AUDIT_KEY → dynamic) — often a configured endpoint, not necessarily third-party
Audit where credentials are sent. A NOTION_TOKEN should only reach api.notion.com — never a third-party host.
Secrets not logged
1 secret value sent to error
Redact or omit secret values from log output.
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.
Domain consistency
npm scope @czagents doesn't match GitHub owner martinhavel
Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.
