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
236/236 tools missing one or more hints — set_board_size (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); set_board_origin (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_board_origin (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +233 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
193/221 tool handlers declare input schemas (87%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 3/221 tool handlers wrap calls in try/catch (1%)
Wrap each tool handler body in try/catch and return a structured error response.
Tool test coverage
182/236 tools referenced in tests (77%)
Write tests that reference each tool by name so every tool has at least one test.
No access to sensitive paths
Reads sensitive paths: ~/.config/Claude/logs, ~/.config/Claude/logs
Remove reads of sensitive system paths. If you genuinely need them, document why in the README.
Shell command execution
5 child_process/subprocess calls in production code — runs shell commands (src/server.ts:198, src/server.ts:375, src/server.ts:430)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Production dependencies are patched
0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.21.0 (high), @modelcontextprotocol/sdk@1.21.0 (high)
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.

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.
