Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (5)

check_transactionCheck one crypto transaction for scams, address mistakes, and other risk signals.
check_transactions_batchCheck up to 1,000 crypto transactions in one request. Returns a compact summary by default so large batches do not overwhelm an AI agent's context. Set detail_level='full' when individual results are needed.
get_usage_statusCheck your current PathGuard plan, monthly scan quota, and usage.
preflight_transactionRun PathGuard's full transaction checks and return an ALLOW, REVIEW, or BLOCK decision.
report_scam_addressReport a suspected scam address to PathGuard's community reporting system.

Schemas: list_tools.
