"How to send an email" matching MCP servers:

An MCP server that sends plain-text Gmail messages only to a predefined allowlist, using generated recipient IDs instead of email addresses to enforce security.

MCP server that gives an AI assistant simultaneous access to multiple Gmail accounts with per-account read-only, draft, or send tiers, two-phase write confirmation, and safeguards for handling untrusted email content.

Email validation MCP server using MailboxValidator API to determine validity of an email address.

Enables an MCP client to read, draft, organize, send, and delete email across multiple Gmail and Exchange Online/Outlook.com accounts, with per-account capability policies, recipient allowlists, confirmations, minimum OAuth scopes, and local audit logging.

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.

A local MCP server for Gmail with strict alias whitelisting, allowing AI clients to search, read, reply to, and send emails only from explicitly whitelisted alias addresses while keeping all other mailbox content unreachable.

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.

Routes web requests from AI tools through Tor for anonymized fetching, with selective per-URL routing to bypass Tor-blocking sites.

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.

An MCP front-end for AnB. The tool surface is "use-don't-reveal": no tool returns a plaintext secret. Reveal paths require a TTY the server doesn't have, so the no-reveal guarantee is structural, not prompt-based — it holds even against a prompt-injected agent. Runs as a dedicated, narrowly-scoped AnB identity; exec is default-deny (only allowlist rules tagged scope=mcp run); command output

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 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.

Connects MCP-compatible AI agents to the AGLedger API for change control, recording every change with signed, hash-chained records. Provides API pass-through tools and an offline audit verifier.
