Category & Scope

Tools & Capabilities Breakdown

Proximo Tools (7)

audit_entries

READ-ONLY: WHO changed WHAT and WHEN — guest configuration changes and every other audited action, read back from the PROVE ledger. Newest first. This is how you answer "who changed this guest" or "what has this caller done". `matched` counts entries passing your filters, `total` counts the whole ledger, and `truncated` says so when `limit` cut rows. An entry with no principal returns null plus a note: the ledger not capturing an identity is a fact about the log, never a claim that nobody was responsible. This READS the chain; `audit_verify` PROVES it is intact.

audit_verify

Verify the tamper-evident audit ledger's hash chain — PROVE the log is intact. Pass `expected_head` (the head() value you pinned off-box) to also catch tail truncation, a forged tail-append, or a full file replacement — a forward walk alone can't see those. Falls back to PROXIMO_AUDIT_EXPECTED_HEAD when omitted.

proximo_call

Call any Proximo tool by exact name, including ones not in this server's listed tools. Get the argument shape from proximo_tool_schema first. Same gates as calling it directly: dry-run PLAN, ledger entry, token ACL. A smaller doorway, not a looser one.

proximo_recall
