lookup_lightning_channels_per_node
Lookup all Lightning Network channels for a given node by public key.
get_recommended_lightning_peers
Get recommended Lightning Network peers for a given node. Returns nodes that are NOT currently peered with the specified node but would improve its centrality score if connected.
search_lightning_nodes_by_alias
Search for Lightning Network nodes by partial alias match. Returns nodes whose aliases contain the search term (case-insensitive).
domain_rdap
Queries the authoritative RDAP registry for a domain. Returns availability status (HTTP 404 = available), and for registered domains: registrar name, registration/expiration dates, nameservers, DNSSEC status, and domain status flags. Uses IANA bootstrap to find the correct RDAP server per TLD. Cover
parse_hostname
Parse a hostname into its constituent parts using the Mozilla Public Suffix List (9700+ entries). Returns eTLD (effective TLD), registered domain, subdomain, labels, and depth. Handles multi-level eTLDs (co.uk, co.jp, com.au) and platform suffixes (github.io, herokuapp.com).
is_subdomain
Check whether a hostname is a subdomain (has labels beyond the registered domain). Uses the Mozilla Public Suffix List for accurate eTLD detection.
registered_domain
Extract the registered domain (eTLD+1) from a hostname. For example, www.mail.example.co.uk returns example.co.uk.
tld_info
Get information about a top-level domain or effective TLD. Returns whether it is in the Public Suffix List, how many sub-suffixes exist, and classification (ccTLD, gTLD, or infrastructure).
reverse_lookup_cname
Find hostnames that have a CNAME record pointing to the specified target. Useful for CDN and load balancer investigations.
historic_reverse_lookup_cname
Find hostnames that previously had a CNAME record pointing to the specified target but no longer do. Tracks CDN and infrastructure migrations.
ip_geolocation
Get geographic location data for an IP address: country, city, region, latitude, longitude, timezone.
ip_network
Get the containing network (BGP route), AS number, AS name, and route description for an IP address.
ip_to_asn
Lightweight lookup: get just the AS number and netblock for an IP address. Fastest way to map IP to ASN.
ip_blocklist_check
Check an IP address against IPsum, FireHOL, Tor exit node lists, C2 indicators, Roskomnadzor (Russia), and other threat intelligence feeds. Returns which lists the IP appears on and threat scores.
ip_threat_intel
Combined threat intelligence: DNSBL listings, IPsum score, FireHOL lists, bad ASN flag, Tor exit status. Comprehensive threat assessment for an IP address.
as_info
Get the name, organization, country, and description for an Autonomous System number. Lightweight version of as_whois.
as_prefixes
Get all IPv4 and IPv6 network prefixes (netblocks) announced by an Autonomous System. Returns BGP-visible routes.
Get domain popularity rankings from five independent sources: Majestic Million (backlinks), Tranco top 1M (aggregated traffic), Cloudflare Radar (1.1.1.1 DNS query popularity), Cisco Umbrella (OpenDNS query popularity), and Chrome UX Report (real Chrome user traffic).
domain_blocklist_check
Check a domain against HaGeZi DNS blocklists, Steven Black unified hosts, Blackbook malware list, phishing databases, Roskomnadzor (Russia), and Citizen Lab censorship lists. Returns which lists the domain appears on.
dns_differential
Resolve a domain through filtered public DNS resolvers and their unfiltered controls to detect provider threat-feed blocks.
domain_shared_ip
Find other domains hosted on the same IP address(es) as the target domain. Resolves the domain's A records, then performs reverse IP lookups for each.
domain_shared_ns
Find other domains using the same nameserver(s) as the target domain. Resolves the domain's NS records, then performs reverse NS lookups for each.
domain_shared_mx
Find other domains using the same mail server(s) as the target domain. Resolves the domain's MX records, then performs reverse MX lookups for each.
check_email
Verify an email address by connecting to its mail server via SMTP. Checks MX records, tests if the address is accepted (RCPT TO), detects catch-all domains, and reports TLS support. Results are RAM-cached for 1 hour.
ping
Check if the API is responding. Returns status and server timestamp.
lookup_bitcoin_transaction
Returns full transaction details: inputs with addresses and values, outputs with spent status, fee, size/weight, SegWit flag, and Lightning Network channel correlation. Supports both confirmed and mempool transactions.
lookup_bitcoin_address
Returns address balance, total received/sent, transaction counts, address type (P2PKH, P2SH, P2WPKH, P2TR), first/last seen block, and ransomware/abuse flags. Supports all Bitcoin address formats.

Returns block header (hash, timestamp, version, merkle root, difficulty, nonce), transaction count, and list of transaction IDs. Supports lookup by block height.
bitcoin_address_transactions
Returns a paginated list of transactions involving a Bitcoin address. Filter by direction: received (incoming funds), sent (outgoing funds), or all. Returns up to 100 transactions per call, sorted by block height descending (most recent first).
bitcoin_transaction_spends
For a given transaction, returns which subsequent transactions consumed its outputs. Useful for UTXO tracking and chain analysis. Shows the spending txid for each output.
What this means. This server responded to the MCP handshake and listed its tools without authentication. The schema fingerprint lets us flag if tool signatures silently change (schema drift) between checks.
