Ce que fait ce MCP

Anchors document hashes, verifies proofs and signed messages, and provides Doichain names, blocks, transactions, balances, and network status.

anchor_proof

Anchor a proof of existence

Anchor a SHA-256 hash on the Doichain as a tamper-evident timestamp (proof of existence, name poe/<sha256>). Free for users, limited per IP address and day (see get_anchoring_quota). Confirms with the next block, usually within 10 minutes, then check_proof returns block height and time. If the hash is already anchored or pending, the existing proof is returned instead of creating a second one. If an earlier proof of the hash has expired, it stays valid and is returned with expired true. Nothing is registered unless reanchor_expired is true. Only the hash and the optional note and file name become public, never the document itself. The operator of this server pays for the name and holds it. The proof shows that a document with this hash existed no later than the block time, not who submitted it.

check_name_expiry

Check when names expire

Check up to 25 names at once: status (active, expiring_soon, expired, not_registered), blocks left, an estimated expiry date for active names (from the measured block interval) and the real expiry date for expired names. Names expire 36,000 blocks after their last update and are renewed by updating them from the owning wallet.

check_proof

Check a proof of existence

Check whether a SHA-256 hash is anchored on the Doichain (name poe/<sha256>) and since when. Returns status (confirmed, pending, expired, unknown) and at the top level block height, block time, transaction and links of the first anchoring, which is the proof time. If the name was updated later or registered again after it expired (possibly by someone else), that registration is reported separately in latest_registration with its own holder and record, which are not part of the original proof. A confirmed or expired proof shows that a document with exactly this hash existed no later than the block time, not who submitted it.

Address balance and history

Confirmed and unconfirmed balance of a Doichain address in DOI, optionally with its most recent transactions. Invalid addresses return an error with the reason.

get_anchoring_quota

Remaining anchoring quota

How many proofs can still be anchored today (UTC day) within the free public quota for the caller's IP address. Hosted chat apps connect from their own servers, so their users share one quota. Callers that send their own API key in the X-API-Key header have no quota.

hash_text

SHA-256 of a text

For files and for confidential texts compute the hash locally instead (sha256sum file, or Get-FileHash -Algorithm SHA256).

lookup_name

Look up a Doichain name

Read the current value, owner address and expiry of a Doichain name. Unregistered names come back with exists false and status not_registered (the name is free). Expired names have status expired and the real expiry date.

search_names

Search names by prefix

List names that start with a prefix, in the node's order (shorter names first, then byte order). Lists only active names unless include_expired is true. Expired names (for example old poe/ proofs) stay in the chain history and are listed with include_expired. Page through large results with next_after until exhausted is true. Names and values are chosen by arbitrary users (name_untrusted, value_untrusted).

verify_message

Verify a signed message

Check whether a message was signed with the private key of a Doichain address (signmessage format). Only legacy addresses (M... or N...) can sign messages, bech32 addresses (dc1q...) are not supported. Useful to confirm that a statement really comes from the holder of an address.
