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
85/85 tools missing one or more hints — utils_installAgentMaster (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); utils_convertData (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); wallet_a2bPublishMcp (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +82 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 30/85 tool handlers declare input schemas (35%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool test coverage
Only 4/85 tools referenced in tests (5%)
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 (utils/passphrasePrompt.ts:143)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Secrets stay with their owner
1 secret/sensitive value flow into network calls (OAUTH_ISSUER → dynamic)
Audit where credentials are sent. A NOTION_TOKEN should only reach api.notion.com — never a third-party host.
Secrets not logged
1 secret value sent to console.log
Redact or omit secret values from log output.
Production dependencies are patched
0 critical, 1 high severity in production deps — mcp-handler@1.0.7 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
13 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
Dependency freshness
1/20 production deps stale: @gorillapool/js-junglebus@2024-05-06 (2.3y)

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.
