"Google's email service" matching MCP servers:

Enables enterprise-managed authorization for MCP on Azure App Service, with deployable Entra OAuth and a local EMA ID-JAG lab exposing whoami and authorization_model tools.

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.

An MCP server that enables interaction with Xero's Identity Service API, providing OAuth 2 authentication and identity management capabilities through natural language commands.

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

Agent trust & data safety MCP: PII/secret redaction, email validation, sanctions screening, and OSV vulnerability checks for AI agents.

Provides redacted access to a private local knowledgebase for coding agents, allowing them to inspect files while hiding sensitive names and identifiers.

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.

A thin MCP server that wraps provenance-receipts and quality-gate services as tools, enabling AI agents to certify content origin and score quality via Ed25519-signed receipts.

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.

Self-hosted, multi-account Gmail MCP server for Claude and Codex over Streamable HTTP, with explicit account aliases, owner-only OAuth, and encrypted credential storage. Supports searching and reading email, creating drafts, and optional sending and label changes.

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.

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.

Human-in-the-loop approval: a person approves the exact AI action with a passkey, and any service can check the signed approval offline.

Compare service-grant changes, tool alias origins, and saved MCP tool definitions with Gooo rules. Reports preserve incomplete-capture uncertainty and source bindings. No grants are applied and no compared tools are invoked.

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