// key findings
⚠️
Known vulnerabilities in dependencies: 3 high
Affects packages this MCP installs at runtime. Upgrade or remove the affected dependency.
✅
No credential exfiltration, no sensitive file access, no obfuscation
Static analysis found nothing flowing your secrets to unexpected places.
✅
Open source with a license and README
Anyone can audit the code, the license is declared, and the publisher documents what it does.
🔐
You'll be asked for 3 credentials: BOOTSTRAP_ADMIN_PASSWORD, SECRET_ENCRYPTION_KEY, VAULT_TOKEN
These are read from process.env at runtime. Make sure you trust where they’ll be sent.
// tools this server exposes17 tools

These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.

sys_list_clients
sys_get_client

Get full detail for one registered client, including its tools and health.

sys_list_tools

List every (client, tool) pair across every registered client, live or not.

sys_list_bundles

List admin-curated MCP bundles (cross-client tool + composite selections served at /mcp-custom/:bundleName).

sys_list_keys

List managed MCP API keys (metadata only — raw key values are never retrievable after creation).

sys_metrics

Snapshot of gateway metrics: uptime, active sessions, tool-call counts, average latency.

sys_audit_tail

Tail the admin audit log (most recent entries first).

sys_diagnose
sys_set_client_enabled

Enable or disable a registered client (all its tools become unreachable while disabled).

sys_set_tool_enabled

Enable or disable a single tool on a registered client.

sys_set_guard
sys_reset_circuit_breaker

Force a live client's circuit breaker back to closed.

sys_register_client
sys_delete_client
sys_create_bundle
sys_mint_key
sys_revoke_key

Revoke a managed MCP API key by id. Destructive: pass {"__confirm": true} or use an elevated credential.

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

17/17 tools missing one or more hints — sys_list_clients (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); sys_get_client (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); sys_list_tools (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +14 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.

Production dependencies are patched

0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.12.0 (high), @modelcontextprotocol/sdk@1.12.0 (high)

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

Dependency freshness

2/10 production deps stale: ajv-formats@2024-03-30 (2.5y), swagger-ui-express@2024-05-31 (2.3y)

// 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 3 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
