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.
Better Auth: OAuth refresh-token replay via missing client authentication on oidc-provider and mcp plugins
@hono/node-server has authorization bypass for protected static paths via encoded slashes in Serve Static Middleware
@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
Better Auth has insecure cryptographic defaults in oidcProvider: alg=none advertised and plain PKCE accepted by default
DATABASE_URLPORTTool annotations
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
5/5 tools missing one or more hints — ping (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_notes (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); create_note (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +2 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
3/5 tool handlers declare input schemas (60%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Production dependencies are patched
1 critical, 11 high severity in production deps — better-auth@1.6.9 (critical), @hono/node-server@1.13.8 (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.
