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

2/2 tools missing one or more hints — mcp_server_tool_call (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); listmcptoolsrestapiresponseobject (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint). 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 handlers catch errors

Only 0/1 tool handlers wrap calls in try/catch (0%)

Wrap each tool handler body in try/catch and return a structured error response.

Tests exist

No test files found

Add tests that exercise each declared tool.

No access to sensitive paths

Reads sensitive paths: /.dockerenv

Remove reads of sensitive system paths. If you genuinely need them, document why in the README.

No eval / new Function

5 eval() or new Function() calls — dynamic code execution

Replace eval / Function with explicit parsing or safer alternatives.

Shell command execution

29 child_process calls — runs shell commands

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

Readable source code

2 files appear obfuscated

Ship unminified, readable source.

Secrets stay with their owner

1 secret/sensitive value flow into network calls (LOG_TOKENS → dynamic)

Audit where credentials are sent. A NOTION_TOKEN should only reach api.notion.com — never a third-party host.

Secrets never reach shell commands

2 secret values passed to shell commands — possible command injection

Never pass secrets through shell commands. Use library APIs that accept credentials as arguments.

Secrets not written to files

1 secret value written to files

Avoid persisting secrets to disk. Keep them in memory or your secret manager.
