Hedera Toolbox
Production MCP server giving AI agents metered access to live Hedera blockchain data. Query token prices, screen identities, monitor governance, write tamper-evident HCS compliance records, and analyze smart contracts — all paid in HBAR micropayments per call.

6/33 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
33/33 tools missing one or more hints — get_terms (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); confirm_terms (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); account_info (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +30 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.
Tests exist
No test files found
Add tests that exercise each declared tool.
Production dependencies are patched
0 critical, 10 high severity in production deps — axios@1.13.5 (high), axios@1.13.5 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
