MCP server for the Z1N Protocol - on-chain identity for AI agents on Polygon

What it does

ONLINE Z1N answered an MCP connection on 02 Nov 2026 and introduced itself as z1n 0.2.0 (MCP protocol 2025-06-18).

6 tools offered to AI assistants

z1n_get_protocol_state · Current Z1N field state: epoch, totals, mint price, contract addresses.
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_key · One Key: glyphs, owner, signal and attestation counts, recent signals.
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_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.

What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method

Is this your server? Monitoring Pro: a check every 30 minutes and an email within the hour when it stops answering. Launch offer: $39.99 once, for life.
