"Developing a Bulk Email System" matching MCP servers:

Enables AI assistants to search, retrieve, and send email across multiple ordinary IMAP, POP3, and SMTP mailboxes, with per-account permissions and safe sending checks.

Audits email deliverability configuration for a domain, checking SPF, DKIM, DMARC, and MX records, returning a score and recommendations.

Comprehensive email validation MCP server that checks syntax, MX records, disposable domains, role-based accounts, SPF/DKIM, typo suggestions, and risk scoring.

Provides email verification as a tool, performing syntax validation, domain verification, and disposable-domain risk detection.

An MCP server that provides email verification, bulk list cleaning, and signup risk assessment tools. It exposes three typed tools for agents: verify_email, clean_email_list, and assess_signup_risk, with real DNS MX checks and disposable domain detection.

A Model Context Protocol server that provides LLM Agents with a comprehensive toolset for IP geolocation, network diagnostics, system monitoring, cryptographic operations, and QR code generation.

MCP server that enables AI agents to check if email addresses or domains are disposable using the isitdisposable.com API. It provides tools like check_email, check_domain, and check_batch for real-time validation.

Provides email validation and domain configuration auditing tools for AI assistants, enabling single address checks, bulk list cleaning, SPF verification, and full mail setup grading (A-F) with actionable fixes.

An MCP server that reads a file's embedded C2PA Content Credential to report whether it declares AI generation or a real-world capture, and checks whether that declaration's signature still verifies against the file's current bytes.

A read-only MCP server that enables Claude to audit Firewalla network security configurations and monitor network activity. It provides tools to inspect devices, rules, alarms, and traffic flows without making any changes to the Firewalla system.

Enables AI agents to read and send email, handle attachments and manage calendar invitations through their own IMAP/SMTP mailboxes, with per-mailbox sender and recipient allow lists and automatic HTML-to-Markdown conversion. It runs as a single self-hosted Docker container, exposing the same tools over MCP and REST.

An MCP server that checks SPF, DKIM, DMARC, and MX records for a domain, returning a health verdict and specific DNS fixes to improve email deliverability.

Enables AI-powered analysis of Rapid7 vulnerability and asset data by exporting via the Bulk Export API and making it queryable through natural language or SQL in MCP-compatible tools.

Enables AI agents to perform passive security scans on domains, checking email spoofing (DMARC/SPF/DKIM), TLS weaknesses, security headers, exposed files, and subdomain-takeover risk without needing an API key.

Enables agents to verify postal addresses, email addresses, and phone numbers against Melissa's Global Verification APIs before acting on the data, including batch verification and a per-session call budget to prevent runaway costs.

Enables AI assistants to read identification verdicts, search history, summarize entities, explain risk scores, and verify webhook signatures through read-only tools over stdio or streamable HTTP.

▎ Check an email before an AI agent sends it: send / ask a human / block — with machine reason codes and prompt-injection detection.

Email-deliverability tools for AI agents — 12 MCP tools across email verification, DNSBL across 50 zones, SPF/DKIM/DMARC analysis, spam-trap scoring, domain intelligence, and email finder. Free tier with no credit card.

Exports vulnerability and asset data from Rapid7 Command Platform via the Bulk Export API into a local DuckDB database, enabling AI assistants to run natural language queries and SQL analysis with sandboxed security.

Gives AI agents verifiable, tamper-evident receipts for their actions — attest_action signs a cryptographic receipt for what the agent did (email sent, payment made, form filed), verify_receipt checks it offline, get_identity returns the agent's did:key. Sign locally, verify anywhere, zero backend.
