88 dependencies, 1 flagged: @playwright/test
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
7/7 tools missing one or more hints — view_location (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); fly_to_corridor (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); radar_scan (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +4 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
6/7 tool handlers declare input schemas (86%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 1/7 tool handlers wrap calls in try/catch (14%)
Wrap each tool handler body in try/catch and return a structured error response.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
No hardcoded API keys
1 live-looking API key in source: 1 Google API key
Move secrets to environment variables (process.env.X) or your secret manager.
Tool test coverage
Only 0/7 tools referenced in tests (0%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
4 child_process calls — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Secrets stay with their owner
3 secret/sensitive values flow into network calls (FIRMS_MAP_KEY → dynamic, IOM_DTM_API_KEY → dynamic) (2 other flows matched canonical API hosts)
Audit where credentials are sent. A NOTION_TOKEN should only reach api.notion.com — never a third-party host.
Secrets not logged
2 secret values sent to console.log
Redact or omit secret values from log output.
Production dependencies are patched
2 critical, 11 high severity in production deps — next@15.1.0 (critical), next@15.1.0 (critical)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
3 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.

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.
