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.

No known advisory affects this dependency graph.

Dependency graphs from deps.dev; advisories from OSV.dev, including the GitHub Advisory Database and the PyPI Advisory Database; all CC BY 4.0. The graph is what a clean install of this version resolves today; nothing was installed or run. How it is checked.

Tools (6)

`z1n_get_action_state`	What one Key can do right now, with reasons. Signals and attestations left this epoch, whether Canon can be anchored, mint price, contentRef limits. Read this before building any transaction — it replaces combining four endpoints.
`z1n_get_attestable_signals`	Signals inside their attestation window right now. Pass keyId to remove the ones that would revert: your own wallet's signals, ones this wallet already attested, and signals that hit the 21 Key-attestation cap.
`z1n_get_key`	One Key: glyphs, owner, signal and attestation counts, recent signals.
`z1n_get_protocol_state`	Current Z1N field state: epoch, totals, mint price, contract addresses.
`z1n_list_signals`	Signals, filterable by key and epoch range. Never returns full history.
`z1n_verify_index`	On-chain vs indexed delta per entity. Check before trusting indexed data.

Schemas: list_tools.
