"MCP servers that can be triggered by uvx or npx" matching MCP servers:

Enables AI agents to analyze whether they should send an email, evaluating passive aggression and regret probability with a recommendation heavily weighted toward no.

Give AI agents their own email inboxes. Create, send, receive, and manage email entirely via MCP tools.

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.

An email MCP server that lets Claude or any MCP client search, read and draft mail via IMAP, treating every message as untrusted input. It prioritizes safety with plain-text-only bodies, disabled sending until an allowlist is set, and no bcc support.

Diagnoses a domain's email authentication — SPF, DMARC, DKIM, MX, blacklists and domain or SSL expiry - and returns copy-paste fix records generated by a validating engine, never a language model. The MCP server is hosted remotely; this repository carries the plugin manifest, connector config and bundled skill.

Gives an AI assistant read- and draft-only access to a single personal Microsoft mailbox, letting it search, list and read mail, browse folders, save attachments to a jailed directory, and create new or reply drafts. It requests no send scope, so mail can never be sent, deleted, moved or marked, and calendar, contacts and files are untouched.

A read-only MCP server for Gmail and Drive with only 5 tools, designed to be friendly to small local LLMs by minimizing context usage and simplifying inputs.

A Gmail MCP server that enables Claude to send, search, and read emails using either Gmail API or SMTP/IMAP backend.

MCP server that gives an AI agent a throwaway test identity — a real disposable email address and a real UK phone number — so it can sign up for something it's testing and read back the verification email/SMS itself, without a human in the loop.

Enables AI agents to publish static sites and build folders as live websites, push updates, provision and manage custom domains with DNS, and send transactional email. Ships as a local pip/uvx server that reads build folders directly, or as a hosted HTTP endpoint for Claude Code, Claude Desktop, and other MCP clients.

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.

Enables email address verification through a single MCP tool, returning whether an address is valid, invalid, or risky.

MCP server that enables AI agents to search and read locally-archived emails via the Bichon email archiver API, without exposing Gmail or IMAP credentials.

Connects an MCP client to an existing classic Outlook session on Windows so agents can browse stores and folders, list recent messages, run literal text and metadata searches, and read plain-text bodies with attachment metadata. All access is strictly read-only, with no sending, deleting, moving, or network connections of its own.

A native MCP server for real-time B2B contact finding and SMTP email validation, scraping company websites, Discord, and Telegram to deliver live, verified contacts that AI agents like Claude and Cursor can query directly.

Give Claude (or any MCP client) a real email inbox and SMS. Your AI agent can read and send email, manage inboxes, track delivery, and handle SMS.

A secure email gateway MCP server that protects AI agents from prompt injection attacks by scanning emails for malicious instructions before they reach the agent.

A local MCP server that lets Claude read macOS Mail.app via JXA, with tools for listing accounts/mailboxes, searching and reading messages. Read-only by default, with optional opt-in write tools for compose drafts and Apple Calendar events.

Enables MCP clients to read and search Proton Mail and create draft-only emails with attachments through the local Proton Mail Bridge, while requiring out-of-band human approval before a draft can be committed.

MCP server that enables email management (send, read, search, delete, etc.) via IMAP/SMTP, compatible with Gmail, Outlook, Yahoo, iCloud, and other standard mail servers.
