On 2026-11-03 the server answered initialize and tools/list without a sign-in. First answer in 326 ms.

• Its tools do every use case we checked: check whether an IP address has attacked servers; report SSH brute-force sources from fail2ban; download a blocklist for firewall rules.
• Checked on 1 of the 7 days it takes to judge reliability.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

• Every tool passes all six checks.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• check_ip

  Reputation of one IPv4 or IPv6 address: abuse confidence score (0-100, 75+ is on the blocklist), number of reports and distinct reporters, attack categories, country, network owner (ASN), Tor exit status and a link to its page. Set…

• get_reports

  The individual abuse reports filed against one address, newest first, with time, categories, comment (usually log lines) and reporter. Paginated.

• check_network

  Every reported address inside a CIDR block (IPv4 up to /16, IPv6 up to /48), with score, report count and last report time, plus the network's owner. Use it to judge a whole hosting range or subnet.

• report_ip

  File an abuse report against an address that attacked a system you run. Needs an API key. Use category codes from list_categories (e.g. ssh,brute-force) and put the evidence (log lines, never personal data) in the comment. Each reporter…

• get_blocklist

  The highest-confidence abusive addresses right now, best first, with score, country and categories. Needs an API key and counts as one blocklist download. For a firewall-ready file, point the firewall at the blocklist URL instead (see the…

• list_categories

  All attack categories with their code, numeric ID, group and when to use them. Use the codes with report_ip.

• get_statistics

  What the database sees right now: reports in the last 24 hours, addresses on the blocklist, and over the last 30 days the top attack categories, countries, networks and highest-scoring addresses.

• get_country_report

• get_network_report

  Abuse reported against one autonomous system in the last 30 days: number of reported and blocklisted addresses, the worst addresses, attack categories and countries. Useful to judge a hosting provider or ISP.
