Robtex MCP server

Robtex is a remote MCP server that gives an AI agent 46 tools, among them as_info, as_prefixes, bitcoin_address_transactions. It answers at https://mcp.robtex.com/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 5 September 2026; the last check, on 18 October 2026, succeeded.

DNS, IP, AS, domain reputation, and Lightning Network intelligence (44 tools)

Description as the publisher wrote it.

The 46 tools Robtex offers

Tool	What it does
`as_info`	Get the name, organization, country, and description for an Autonomous System number. Lightweight version of as_whois. Inputs: asn
`as_prefixes`	Get all IPv4 and IPv6 network prefixes (netblocks) announced by an Autonomous System. Returns BGP-visible routes. Inputs: asn
`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 fir Inputs: address, direction
`bitcoin_blockchain_stats`	Returns cumulative blockchain metrics over a configurable block range. Available metrics include: txs, fees, segwittx, inputs, outputs, insats, outsats, btcusd, volusd, unspentoutputs, fullyspent, unspentsats, addresses, satoshiblocks, clno Inputs: metric, startBlock, endBlock, samples
`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. Inputs: txid
`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. Inputs: email
`dns_differential`	Resolve a domain through filtered public DNS resolvers and their unfiltered controls to detect provider threat-feed blocks. Inputs: domain
`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. Inputs: hostname
`domain_ranking`	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 Inputs: hostname
`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 I Inputs: domain
`domain_reputation`	Get comprehensive domain reputation: Majestic rank, Tranco rank, HaGeZi blocklist status, Blackbook malware status, phishing database status, HSTS preload status, and disposable email detection. Inputs: hostname
`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. Inputs: hostname, limit
`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. Inputs: hostname, limit
`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. Inputs: hostname, limit
`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. Inputs: pubkey, limit, offset
`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. Inputs: target, limit, offset
`historic_reverse_lookup_ip`	Find hostnames that previously pointed to a specific IP address but no longer do. Tracks hosting migrations and past IP relationships. Searches both A and AAAA records. Inputs: ip, limit, offset
`historic_reverse_lookup_mx`	Find hostnames that previously used a specific mail server but no longer do. Tracks email provider migrations and past MX relationships. Inputs: mx_server, limit, offset

`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. Inputs: ip
`ip_geolocation`	Get geographic location data for an IP address: country, city, region, latitude, longitude, timezone. Inputs: ip
`ip_network`	Get the containing network (BGP route), AS number, AS name, and route description for an IP address. Inputs: ip
`ip_reputation`	Check an IP address reputation against 100+ real-time blocklists (DNSBLs). Returns listing status, threat categories, AS info, and blocklist details. Inputs: ip
`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. Inputs: ip
`ip_to_asn`	Lightweight lookup: get just the AS number and netblock for an IP address. Fastest way to map IP to ASN. Inputs: ip
`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. Inputs: hostname
`latest_lightning_channels`	Returns the most recently opened Lightning Network channels, sorted by open time descending. Inputs: count

`lookup_bitcoin_block`	Returns block header (hash, timestamp, version, merkle root, difficulty, nonce), transaction count, and list of transaction IDs. Supports lookup by block height. Inputs: height
`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. Inputs: txid
`lookup_dns`	Lookup DNS records (A, AAAA, MX, NS, TXT, CNAME, SOA) for a given hostname. Also returns domain reputation info (Majestic, Tranco rankings, blocklist status). Inputs: hostname
`lookup_lightning_channel`	Lookup a Lightning channel by channel ID. Supports numeric, block x txn x vout, or block:txn:vout formats. Inputs: channel_id
`lookup_lightning_channels_per_node`	Lookup all Lightning Network channels for a given node by public key. Inputs: node, limit, offset
`lookup_lightning_node`	Lookup a Lightning Network node by public key. Returns node alias, peer count, channel count, and centrality ranking. Inputs: pubkey
`lookup_mac`	Look up the manufacturer/vendor of a network device by its MAC address. Uses the official IEEE OUI (Organizationally Unique Identifier) database with ~30K entries. Inputs: mac_address
`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 s Inputs: hostname
`ping`	Check if the API is responding. Returns status and server timestamp.
`registered_domain`	Extract the registered domain (eTLD+1) from a hostname. For example, www.mail.example.co.uk returns example.co.uk. Inputs: hostname
`reverse_lookup_cname`	Find hostnames that have a CNAME record pointing to the specified target. Useful for CDN and load balancer investigations. Inputs: target, limit, offset

46, as returned by the server's own tools/list on 31 August 2026: as_info, as_prefixes, bitcoin_address_transactions, bitcoin_blockchain_stats, bitcoin_transaction_spends, check_email, dns_differential, domain_blocklist_check, and 38 more.

Is Robtex down?

It answered our last check on 18 October 2026 in 175 ms. Over 10 checks since 5 September 2026 it answered 10.

How do I add Robtex to Cursor?

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mcp.robtex.com/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.

Does Robtex need an API key?

It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

Where this comes from

Publisher: com.robtex. Endpoint host: mcp.robtex.com. ARD identifier: urn:air:com.robtex:mcp:mcp. First indexed 31 August 2026. The tools are exactly what the server returned; nothing on this page is inferred from its name. Ranking in Neuronto search is never for sale.
