9/17 tools have annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
14/17 tools missing one or more hints — eth_generate_contract (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); eth_compile_contract (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); eth_deploy_contract (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +11 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 handlers catch errors
15/17 tool handlers wrap calls in try/catch (88%)
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.
Production dependencies are patched
1 medium severity in production deps
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
