// key findings

🚨

Known vulnerabilities in dependencies: 3 critical, 12 high

Affects packages this MCP installs at runtime. Upgrade or remove the affected dependency.

🔐

You'll be asked for 3 credentials: BETTER_AUTH_SECRET, BOOTSTRAP_USER_PASSWORD, OIDC_CLIENT_SECRET

These are read from process.env at runtime. Make sure you trust where they’ll be sent.

// known CVEs in dependencies3 critical12 high2 low

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

Tool 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

42/42 tools missing one or more hints — metamcp_list_mcp_servers (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); metamcp_get_mcp_server (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); metamcp_create_mcp_server (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +39 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.

README present

No README found

Add a README.md describing the server and its tools.

License file

No license file

Add a LICENSE file (MIT, Apache-2.0, etc.).

Tool test coverage

Only 0/42 tools referenced in tests (0%)

Write tests that reference each tool by name so every tool has at least one test.

Shell command execution

1 child_process/subprocess call in production code — runs shell commands (src/lib/stdio-transport/process-managed-transport.ts:152)

Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.

Production dependencies are patched

2 critical, 12 high severity in production deps — better-auth@1.4.18 (critical), shell-quote@1.8.3 (critical)

Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

Dev dependencies

1 critical/high in dev-only deps (does not ship to users)

Upgrade dev dependencies when convenient.

// full audit trail

The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.

// improvement guidance — verified publishers only

We have 8 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
