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

49/49 tools missing one or more hints — aha_generate_embeddings (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); aha_embedding_status (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); aha_pause_embeddings (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +46 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

43/49 tool handlers declare input schemas (88%)

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

Tool handlers catch errors

47/49 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 2/49 tools referenced in tests (4%)

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

Shell command execution

7 child_process calls — runs shell commands

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

Secrets not logged

1 secret value sent to console.log

Redact or omit secret values from log output.

No arbitrary install scripts

Has postinstall/preinstall script — runs arbitrary code on npm install

Remove postinstall/preinstall hooks unless they’re essential.

Production dependencies are patched

0 critical, 12 high severity in production deps — axios@1.12.2 (high), axios@1.12.2 (high)

Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

Dependency freshness

1/9 production deps stale: sqlite@2023-11-01 (2.6y)
