Every change Wellknown observed on this MCP server, newest first, with what it was before and what it became. Tool-surface changes carry the definition diff. Nothing here is edited after the fact.
Added "dns_lookup", "dns_release", "dns_renew" and 3 more (38 tools before, 44 now)
Read a rented name (free) — FREE: what we serve for a name under 448c.net -- its records, its owner and when it expires. No signature and no account: the zone is public, so reading it is too. Complaints, questions, quote requests, or a service you wish we had: POST /feedback on this host -- free, no account. Every report is read and analysed daily; there is no individual reply.
Give up a name you own (free) — FREE: release a name you own before it expires. It stops resolving at once. There is no refund and no undo, and the label is free for anyone else to rent. Ownership is proved by the paying wallet, with no account: send any placeholder signature once and the refusal returns details.expected -- the exact message to sign, in both forms (EIP-191 for a 0x wallet, ed25519 as 'solana:<base58 pubkey>:<base58 sig>'). Complaints, questions, quote requests, or a service you wish we had: POST /feedback on this host -- free, no account. Every report is read and analysed daily; there is no individual reply.
Extend a rented name (paid, x402) — PAID: push a name you own further out by another year. What it resolves to is untouched; only its expiry moves, and a repeated payment extends it rather than resetting it. The payer must be the owner. Returns the new and previous expiry. Call it once without payment to receive the price as an x402 PaymentRequired (Base USDC, and Solana USDC where offered); call it again with a signed payment in _meta['x402/payment'] to complete it. The receipt comes back in _meta['x402/payment-response']. No account, no API key. Complaints, questions, quote requests, or a service you wish we had: POST /feedba…
Rent a name under 448c.net (paid, x402) — PAID: rent <label>.448c.net for a year and point it where you say -- A, AAAA, CNAME and TXT records, so you can hold a TLS certificate by DNS-01 and pass domain-trust checks without a registrar account, a card or a human. The paying wallet owns the name. Returns the name, its owner and when it expires; repoint it with dns_set_records, extend it with dns_renew. Call it once without payment to receive the price as an x402 PaymentRequired (Base USDC, and Solana USDC where offered); call it again with a signed payment in _meta['x402/payment'] to complete it. The receipt comes back in _meta['x402/…
Take one free name for 24 hours (free) — FREE: one 24-hour name per wallet, so you can try the zone before paying -- the same label rules and records as dns_rent. Rent a year with dns_rent when it works. The message you sign commits to the literal subject `free`, not to the label. Ownership is proved by the paying wallet, with no account: send any placeholder signature once and the refusal returns details.expected -- the exact message to sign, in both forms (EIP-191 for a 0x wallet, ed25519 as 'solana:<base58 pubkey>:<base58 sig>'). Complaints, questions, quote requests, or a service you wish we had: POST /feedback on this host -- f…
Repoint a name you own (free) — FREE: replace the whole record set of a name you own -- never merged. The rental window is untouched: repointing a name you already paid for costs nothing. Ownership is proved by the paying wallet, with no account: send any placeholder signature once and the refusal returns details.expected -- the exact message to sign, in both forms (EIP-191 for a 0x wallet, ed25519 as 'solana:<base58 pubkey>:<base58 sig>'). Complaints, questions, quote requests, or a service you wish we had: POST /feedback on this host -- free, no account. Every report is read and analysed daily; there is no individual repl…
Added "create_inbox", "free_inbox", "inbox_status" and 2 more (33 tools before, 38 now)
Get a disposable email address (paid, x402) — PAID: get a throwaway email address on a domain we own, live for 24 hours, to receive the verification mail a signup demands. RECEIVE ONLY -- nothing is ever sent from it, ever. Returns the address, the inbox id and when it expires; read what arrives with read_inbox, which is free and never charges again for a code you already paid for. Pay again passing the same id to extend that same address from its current expiry, with no cap -- a repeated payment is never refused and never resets. Call it once without payment to receive the price as an x402 PaymentRequired (Base USDC, and Solana USDC whe…
Take the one free inbox your wallet may hold (free) — FREE: one live inbox per wallet for one hour, identity by your signature alone, so you can receive one code before paying for the 24 h tier. A sibling of create_inbox, not a discount on it: one address, one hour, and the next one has to be bought. Ownership is proved by the paying wallet, with no account: send any placeholder signature once and the refusal returns details.expected -- the exact message to sign, in both forms (EIP-191 for a 0x wallet, ed25519 as 'solana:<base58 pubkey>:<base58 sig>'). Complaints, questions, quote requests, or a service you wish we had: POST /feedback on this ho…
Check an inbox (free) — FREE: the address, when it expires and how much mail is waiting in an inbox you own. Signed under its own domain, separate from the one read_inbox uses. Ownership is proved by the paying wallet, with no account: send any placeholder signature once and the refusal returns details.expected -- the exact message to sign, in both forms (EIP-191 for a 0x wallet, ed25519 as 'solana:<base58 pubkey>:<base58 sig>'). Complaints, questions, quote requests, or a service you wish we had: POST /feedback on this host -- free, no account. Every report is read and analysed daily; there is no individual reply.
Added "pay_receipt", "pay_requirements" and "pay_send" (30 tools before, 33 now)
Read a delivery receipt back (free) — FREE and unauthenticated: read a pay_send receipt back by id -- what the seller answered, when, and what the chain says became of your authorization. Deliberately NOT wallet-scoped: the point is that the seller you are arguing with can fetch it without holding your wallet. Complaints, questions, quote requests, or a service you wish we had: POST /feedback on this host -- free, no account. Every report is read and analysed daily; there is no individual reply.
Read a seller's x402 price card (free) — FREE: ask a seller, unpaid, what it charges, and get back the accepts[] of its own 402 -- the exact PaymentRequirements you have to sign before pay_send can deliver anything. No payment is sent to the seller and none is taken from you. Every seller outcome answers: a 402 returns accepts[], a seller that wants no payment returns accepts null, and a seller that never answered says so. Complaints, questions, quote requests, or a service you wish we had: POST /feedback on this host -- free, no account. Every report is read and analysed daily; there is no individual reply.
Deliver an x402 authorization you signed, and check the chain (paid, x402) — PAID: deliver an x402 authorization YOU signed to a seller exactly once, then read the chain for what actually became of it, and get back an immutable receipt of what the seller answered. Read the price to sign with pay_requirements first; we never sign on your behalf. A seller 402, 4xx, 5xx or refused connection is a delivered, billable answer -- what you buy is the truth about what the seller did with your authorization. The receipt is free to re-read with pay_receipt, so a seller who says they were never paid can be shown it. Call it once without payment to receive the price as an x402 Pay…
Added "check_address" and "check_url" (28 tools before, 30 now)
Check an EVM address against public risk feeds (paid, x402) — PAID: check an EVM address against public risk feeds (OFAC, community darklists, on-chain age) and get back a verdict, score and reasons in the same response the payment settles -- there is no separate read-back call. Charged only on success: if every risk feed is unreachable the request is refused for free (CHECK_SOURCES_UNAVAILABLE) rather than answered with an unsourced verdict. Call it once without payment to receive the price as an x402 PaymentRequired (Base USDC, and Solana USDC where offered); call it again with a signed payment in _meta['x402/payment'] to complete it. The receipt come…
Check a URL against public risk feeds (paid, x402) — PAID: check a URL against public risk feeds (phishing lists, domain age, lexical signals) and get back a verdict, score and reasons in the same response the payment settles -- there is no separate read-back call. Charged only on success: if every risk feed is unreachable the request is refused for free (CHECK_SOURCES_UNAVAILABLE) rather than answered with an unsourced verdict. Call it once without payment to receive the price as an x402 PaymentRequired (Base USDC, and Solana USDC where offered); call it again with a signed payment in _meta['x402/payment'] to complete it. The receipt comes bac…

Read the mail an inbox received (free) — FREE: the mail your inbox received, newest first, with any verification code and link already picked out -- from, to, subject, receivedAt, the plain text, codes[] and links[]. This is how what you bought with create_inbox comes back to you. Poll it with since to see only what arrived after a timestamp; reading never costs, however many times you poll. Ownership is proved by the paying wallet, with no account: send any placeholder signature once and the refusal returns details.expected -- the exact message to sign, in both forms (EIP-191 for a 0x wallet, ed25519 as 'solana:<base58 pubkey>:<bas…
Release an inbox now (free) — FREE: give up an inbox you own before it expires. Its messages go with it and the local part is never issued again; later mail to it is dropped, never bounced. There is no refund and no undo. Signed under its OWN domain, not the one the reads use. Ownership is proved by the paying wallet, with no account: send any placeholder signature once and the refusal returns details.expected -- the exact message to sign, in both forms (EIP-191 for a 0x wallet, ed25519 as 'solana:<base58 pubkey>:<base58 sig>').
