Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

Tool list from our last check. Connect live to refresh it.

check_blacklist

Check whether an IP address or a domain is listed on public DNS blocklists (DNSBLs). A domain is checked on domain blocklists only; to check a mail server, give its IP address.

targetstring, required

One IPv4 or IPv6 address, or one domain name.

Tools (7)

check_blacklist

Check whether an IP address or a domain is listed on public DNS blocklists (DNSBLs). A domain is checked on domain blocklists only; to check a mail server, give its IP address.

read-only

Argument	Type	Description
target*	string	One IPv4 or IPv6 address, or one domain name.

Input schema (JSON)

{
  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",
  "required": [
    "target"
  ],
  "properties": {
    "target": {
      "type": "string",
      "maxLength": 512,
      "description": "One IPv4 or IPv6 address, or one domain name."
    }
  }
}

check_dkim

Check a domain's DKIM public keys in DNS. With a selector (the s= tag of a DKIM-Signature header), checks that selector's key; without one, probes common selector names. Finding no key on common names does not prove DKIM is missing: selectors cannot be listed from DNS.

read-only

Argument	Type	Description
domain*	string	Domain name, for example example.com.
selector	string	DKIM selector, for example google or selector1. Leave out to probe common selectors.

Input schema (JSON)

{
  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",
  "required": [
    "domain"
  ],
  "properties": {
    "domain": {
      "type": "string",

    "selector": {

      "maxLength": 253,
      "description": "DKIM selector, for example google or selector1. Leave out to probe common selectors."
    }
  }
}

check_dmarc

Check a domain's DMARC record: whether it exists and is valid, its policy (none, quarantine or reject), alignment, and where reports are sent.

read-only

Argument	Type	Description
domain*	string	Domain name, for example example.com.

Input schema (JSON)

{
  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",

      "description": "Domain name, for example example.com."
    }
  }
}

check_email_domain

Check everything about a domain's email setup in one call: SPF, DMARC, MX, DKIM on common selectors, domain blocklists, MTA-STS, TLS-RPT and BIMI. Use it for a general question such as "is email set up correctly for example.com".

read-only

Argument	Type	Description
domain*	string	Domain name, for example example.com.

Input schema (JSON)

{
  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",

      "maxLength": 512,
      "description": "Domain name, for example example.com."
    }
  }
}

check_spf

Check a domain's SPF record: whether it exists and is valid, how many of the 10 allowed DNS lookups it uses, and how its all mechanism treats mail from servers that are not listed.

read-only

Argument	Type	Description
domain*	string	Domain name, for example example.com.

Input schema (JSON)

{
  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",

      "maxLength": 512,
      "description": "Domain name, for example example.com."
    }
  }
}

dns_lookup

Look up DNS records of a name. Type ALL (the default) queries A, AAAA, CNAME, MX, NS, TXT, SOA and CAA; any single type can be asked for. An IP address gives its reverse DNS (PTR) lookup.

read-only

Argument	Type	Description
name*	string	Domain name or IP address, for example example.com or _dmarc.example.com.
type	string	Record type; ALL when left out.
