Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

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

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
47/47 tools missing one or more hints — get_account_totals_report (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_aged_payables_summary_report (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_aged_receivables_detail_report (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +44 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 inputs are validated
Only 8/47 tool handlers declare input schemas (17%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tests exist
No test files found
Add tests that exercise each declared tool.
Secrets stay with their owner
1 secret sent to a request target we could not resolve (PASSWORD → 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.
Production dependencies are patched
0 critical, 16 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.
Dependency freshness
1/11 production deps stale: bottleneck@2023-02-22 (3.5y)
Domain consistency
npm scope @fluegeldao doesn't match GitHub owner cryptocultcurt
Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.

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.
