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.

M8ven verifies MCPs across every public registry — install directly from whichever one you prefer.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
Better Auth: OAuth refresh-token replay via missing client authentication on oidc-provider and mcp plugins
When Vitest UI server is listening, arbitrary file can be read and executed
Better Auth: OAuth refresh-token rotation forks the token family on concurrent redemption
@better-auth/oauth-provider's OAuth authorization-code grant allows concurrent redemption when two token requests race the find-then-delete primitive
Better Auth has stored XSS in the auth-server origin via javascript: redirect_uri in oidc-provider and mcp

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
23/23 tools missing one or more hints — analytics_overview (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); comments_delete (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); comments_list (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +20 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 0/23 tools referenced in tests (0%)
Write tests that reference each tool by name so every tool has at least one test.
Production dependencies are patched
1 critical, 11 high severity in production deps — better-auth@1.5.5 (critical), better-auth@1.5.5 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
5 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
Dependency freshness
1/62 production deps stale: gray-matter@2023-07-12 (3.1y)

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.
