Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Nibgate MCP server: verified content discovery, unlock/payment/tip/nibshare ledger (funded held tips appear as pending entries; refunds appear as negative entries; nibshare entries are privacy-safe: no share links), platform stats, reputation leaderboards, and Nibshare link resolution (resolve_share). Tools return JSON matching the public API. All data is public and read-only. Settlements on this server are Arc (chain ID 5042). To check pending tips for any domain, including external sites, GET https://api.nibgate.xyz/hub/tips/held?domain={domain}; this API host checks only its own network. To unlock paid content after discovery, pay over x402: GET https://api.nibgate.xyz/ns/{slug} (or the content access URL) returns 402 with a PAYMENT-REQUIRED header; pay with the Circle Agent Stack CLI (`circle services pay <url> --address <wallet> --chain ARC`) or any x402 client, then retry the same request to receive the content. To tip a page, POST https://api.nibgate.xyz/hub/tips/challenge, pay the returned requirement, then POST the proof to /hub/tips/verify (a successful response confirms the resolved tip) or /hub/tips/hold (unresolved/external creator is held in a per-domain contract with no EOA key; the factory owner/keeper relays release/refund after Hub authorization checks, and the contract trusts recipient arguments. It is claimable by the verified creator and refundable by the payer until claimed; payer control accepts EOA personal_sign or deployed ERC-1271 wallets with a fresh domain/payer-bound message). Completed matching proofs return their original receipt without a second Tip row or Gateway settlement. Preserve the exact proof and request fields when retrying. HTTP 409 payment-proof-already-used rejects a conflicting or unverifiable binding; payment-verification-pending requires reconciliation of an incomplete durable reservation. Never send a fresh payment to recover an ambiguous settlement. Applies to mainnet and testnet; held-tip claim/refund behavior is unchanged. Full guide: https://nibgate.xyz/discovery.md

get_ledger
Advertised by the server during the last successful anonymous check.

Get the public Nibgate activity ledger: recent views, unlocks, payments, tips (including funded pending holds marked status=held), onchain ratings, and privacy-safe nibshare views/unlocks (titles, wallets, amounts, tx — never the private share link) across verified sites. Held tips are pending and do not count toward completed-tip totals; refunds appear as negative tip entries. Use GET /hub/tips/held?domain={domain} to check pending tips for any exact domain, including external sites. Includes wallet addresses, tx hashes, and receipts where available.
