Qué hace este MCP

Anchors hashes and web captures on Bitcoin SV, retrieves and verifies Merkle proofs, and produces portable evidence and timestamp proof bundles.

9 herramientas
archive_url
Archive a web page with an on-chain timestamp
Capture a web page as it looks right now — screenshot and text — and anchor a hash of that capture on-chain. Use this before relying on a page you cite, so a later edit or deletion cannot be denied. Free.
Esquema de entrada 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['url'], 'properties': {'url': {'type': 'string', 'format': 'uri', 'description': 'the page to capture'}, 'thorough': {'type': 'boolean', 'description': 'wait for lazy-loaded content; slower but better for long or image-heavy pages'}}}
batch_timestamp
Timestamp many hashes in one transaction
Anchor a Merkle root over many sha256 digests in a single transaction — far cheaper per item than notarizing each one. Each hash gets an inclusion proof. Priced per call (pay over HTTP with an x402 payment — see /pay).
Esquema de entrada 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['hashes'], 'properties': {'hashes': {'type': 'array', 'items': {'type': 'string', 'pattern': '^[0-9a-fA-F]{64}$'}, 'maxItems': 5000, 'minItems': 1, 'description': 'sha256 hex digests to timestamp together'}}}
get_archive
Retrieve an archived page capture
Fetch the manifest for a previous archive_url capture: when it was taken, and its proof. Free.
Esquema de entrada 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['hash'], 'properties': {'hash': {'type': 'string', 'pattern': '^[0-9a-fA-F]{64}$', 'description': 'the capture hash returned by archive_url'}}}
notarize_hash
Timestamp a hash on-chain
Anchor a sha256 digest in a Bitcoin SV transaction, proving the content existed at this time. Send ONLY the hash — the content never leaves your machine, and bsv.cx cannot see what was hashed. Free. Idempotent: the same hash returns the same record.
Esquema de entrada 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['sha256'], 'properties': {'label': {'type': 'string', 'maxLength': 200, 'description': 'optional public note stored with the proof'}, 'sha256': {'type': 'string', 'pattern': '^[0-9a-fA-F]{64}$', 'description': 'sha256 hex digest of the exact bytes you want to timestamp'}}}
proofpack
Get a portable, pre-verified proof bundle for a transaction
For any CONFIRMED BSV transaction id, get a freshly SPV-verified bundle: BEEF (BRC-62) and BUMP (BRC-74) plus bsv.cx's own self-synced header-tip attestation. bsv.cx fetches the Merkle proof and folds it against block headers it syncs over the BSV P2P network BEFORE serving, so you receive a bundle that already confirms — verifiable by any @bsv/sdk client with no bsv.cx-specific code. Verification itself is free at /spv/verify; this does the fetch + fold + package for you and is priced per call (pay over HTTP with an x402 payment — see /pay).
Esquema de entrada 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['txid'], 'properties': {'txid': {'type': 'string', 'pattern': '^[0-9a-fA-F]{64}$', 'description': 'the confirmed transaction id to package a proof bundle for'}}}
service_status
Check bsv.cx availability
Report whether anchoring is currently working. Call this if a tool reports something stored but not anchored.
Esquema de entrada 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {}}
spv_verify
Verify any Bitcoin proof against bsv.cx's own headers
Verify ANY Bitcoin (BSV) Merkle inclusion proof — a BEEF envelope (BRC-62), a BUMP (BRC-74), or a raw TSC proof — against block headers bsv.cx syncs itself over the BSV P2P network, NOT an explorer. Returns confirmed / rejected / inconclusive. This is the trustless core: you send only the proof (never the root), we fold the root ourselves and check it against a header we hold — so you never have to trust bsv.cx. Works for ANY txid's proof, not just bsv.cx's own anchors. Free.

{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {'beef': {'type': 'string', 'description': 'a BEEF envelope (BRC-62) as hex — easiest input; carries the tx and its merkle path'}, 'bump': {'type': 'string', 'description': 'a BUMP (BRC-74) merkle path as hex; must be paired with txid'}, 'txid': {'type': 'string', 'description': '64-hex txid; required with bump, or with a raw TSC proof'}, 'index': {'type': 'integer', 'maximum': 9007199254740991, 'minimum': 0, 'description': "the transaction's index in the block (raw TSC proof only)"}, 'nodes': {'type': 'array', 'items': {'type': 'string'}, 'description': 'TSC merkle branch nodes as hex, or "*" for a duplicated node (raw TSC proof only)'}, 'height': {'type': 'integer', 'maximum': 9007199254740991, 'minimum': 0, 'description': 'block height (raw TSC proof only)'}}}
verifiable_fetch
Fetch a page with a proof of what was returned
Fetch a URL as readable text AND get a receipt anchoring a hash of the exact bytes returned, so you can later prove what the page said when you read it. Priced per call (pay over HTTP with an x402 payment — see /pay).
Esquema de entrada 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['url'], 'properties': {'url': {'type': 'string', 'format': 'uri', 'description': 'the page to fetch'}, 'thorough': {'type': 'boolean', 'description': 'wait for lazy-loaded content'}}}
verify_hash
Check an existing proof (any protocol)
Look up a sha256 across EVERY bsv.cx protocol — notary timestamps, verifiable-fetch receipts, notarized captures, web-page archives, Merkle batch roots and attestations — and return when it was anchored and the transaction that proves it. A hash anchored by any of these counts as found. Free, and never rate-limited into unavailability.
