Check Usage
Retrieve API usage statistics for DNS and network lookups. Returns current request counts, maximum allowed requests, and any overage errors for both DNS lookups and network operations (HTTP, SMTP, Ping).
MxToolbox provides a suite of network diagnostic and monitoring tools, including DNS lookups, blacklist checks, and email health analysis.
Retrieve API usage statistics for DNS and network lookups. Returns current request counts, maximum allowed requests, and any overage errors for both DNS lookups and network operations (HTTP, SMTP, Ping).
Tool to perform an HTTP test on a domain. Use when you need to assess HTTP connectivity and status for a given domain.
Retrieves BIMI (Brand Indicators for Message Identification) record and diagnostic information for a domain. BIMI allows organizations to display verified logos in email clients. This tool checks: - Whether a BIMI record exists at default._bimi.{domain} - DMARC policy requirements (quarantine or reject needed for BIMI) - DNS resolution details and nameserver information - Related diagnostic checks and recommendations Returns comprehensive lookup data including passed/failed checks, DMARC records, DNS transcript, and related lookups. Use when verifying email branding configuration or troubleshooting BIMI implementation.
Tool to perform a blacklist check on a domain or IP. Use when you need to verify whether a domain or IP is listed in common blacklists.
Runs a DKIM record lookup for a domain and selector to help verify email authentication configuration. The provider requires the lookup argument in domain:selector format; the supplied value is passed through without conversion.
Runs a DMARC record lookup and validation for a domain. Returns record information, passed checks and errors; failed checks and warnings from the lookup are not included in the returned result.
Performs comprehensive DNS health check and retrieves name server records for a domain. Returns detailed diagnostics including: - Name server (NS) records with IP addresses, TTL, and status - DNS configuration health checks (warnings, errors, passed tests) - Query transcripts showing DNS resolution path - Related lookup suggestions (A, MX, SPF records) Use this to diagnose DNS issues, verify name server configurations, or check DNS propagation status.
Tool to lookup MTA-STS record for a domain. Use when validating mail transport security policy.
Retrieves MX records for a domain, including mail server hostnames, priority, TTL and, when available, IP addresses. Missing or unparseable priority and TTL values are returned as zero.
Tool to retrieve SPF records for a specified domain. Use when confirming email sender authorization policies.
Retrieves current statuses for all monitors in the authenticated MxToolbox account, including failing checks and warnings. No parameters are required; monitor queries require a paid API key.
Performs a ping test to check network connectivity and measure round-trip time to a domain or IP address. Returns detailed ping statistics including response time, TTL (Time-To-Live), packet size, and ASN (Autonomous System Number) information. Useful for diagnosing network connectivity issues, measuring latency, and verifying host availability.
Tool to perform an SMTP connectivity test on a domain. Returns diagnostic results including connection status, DNS checks, TLS support, and other email deliverability indicators. Use when verifying SMTP server configuration or troubleshooting email delivery issues for a domain.
The MXToolbox integration connects your Dench AI CRM directly to MXToolbox, so agents can read and act on your MXToolbox data as part of everyday work — answering questions in chat, keeping your CRM in sync, and running automations without anyone copying data between tools.
13 actions are available for agents to invoke on your behalf. Every call runs through MXToolbox's own authorization, scoped to the account you connect.
Sign in to your Dench workspace and open Integrations.
Find MXToolbox and click Connect — you'll authorize access through MXToolbox's own sign-in flow. No API keys or code required.
Ask an agent to use MXToolbox in chat, or call it from an automation.
Manage or disconnect the connection any time from workspace settings.
The Dench MXToolbox integration connects your AI CRM to MXToolbox, so AI agents can work with your MXToolbox data as part of chats, automations, and CRM workflows. You connect your account once, and every agent in your workspace can use it — governed by your workspace permissions.
The MXToolbox integration currently exposes 13 actions, including Check Usage, HTTP Lookup, Lookup BIMI Record, Lookup Blacklist, Lookup DKIM Record, and Lookup DMARC Record. Agents invoke them on your behalf from chat or from automations.
No. You connect MXToolbox from your Dench workspace using MXToolbox's own sign-in and authorization flow — no API keys to copy, no glue code to maintain.
Connections are authorized through MXToolbox's own authentication flow, and Dench stores only the authorization needed to act on your behalf. You can review and disconnect the MXToolbox connection from your workspace settings at any time.
