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

81/81 tools missing one or more hints — a2b_discover (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); bap_friend (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); bap_generate (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +78 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 31/81 tool handlers declare input schemas (38%)

Declare an inputSchema with zod/joi/yup on every tool definition.

Tool handlers catch errors

78/81 tool handlers wrap calls in try/catch (96%)

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

Tool test coverage

Only 1/81 tools referenced in tests (1%)

Write tests that reference each tool by name so every tool has at least one test.

Shell command execution

1 child_process call — runs shell commands

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

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

11 critical/high in dev-only deps (does not ship to users)

Upgrade dev dependencies when convenient.
