"Using mcp-proxy to bridge a remote SSE server to a stdio server" matching MCP servers:

Sends document files (EPUB, PDF, DOCX, etc.) to your Kindle via email using Amazon's Send to Kindle feature.

One-pass agentic inbox triage as an MCP server: fetch unread Gmail → classify (action_needed/fyi/newsletter/noise) → summarize → extract tasks → draft replies as Gmail DRAFTS (never sends) → flag calendar → write a triage report. Four stdio tools (fetch_emails, save_gmail_draft, append_tasks, write_report); the host is the LLM, so it runs keyless in Claude Code. Gmail scopes: readonly + compose

A Model Context Protocol (MCP) server that allows Claude Desktop to send documents directly to your Kindle e-reader.

Enables pushing enriched leads into Instantly or Smartlead campaigns with ICP score gating, deduplication, and dry-run previews via an Apify actor.

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.

An MCP server that enables AI agents to manage Smartlead campaigns, including creating campaigns, updating schedules, managing email sequences, and adding leads, all over SSE.

Provides email sending and receiving via SMTP/IMAP/POP3, supporting major email providers and dynamic authentication for AI assistant integration.

Enables sending correctly threaded email replies through Proton Mail Bridge using SMTP with proper In-Reply-To and References headers, avoiding IMAP draft pitfalls.

A remote MCP server that proxies tool calls to the caller's own Composio account, using their own API key for each request to access services like Gmail, Slack, and Google Sheets.

Enables sending documents (Markdown, PDF, EPUB) directly to a Kindle via Amazon Send-to-Kindle email, with Markdown converted to EPUB using pandoc.

Enables AI apps to securely read, search, organize, draft, attach files to, and send email across up to five self-hosted IMAP/SMTP mailboxes, with sending only after explicit user approval.

Enables AI assistants to read and search Proton Mail inbox through Proton Mail Bridge, providing tools to list mailboxes, list messages, search messages, and fetch full message bodies. Read-only, with secure certificate pinning.

Professional Proton Mail management with 20+ tools, advanced analytics, and seamless Proton Bridge integration.

Enables AI assistants to read, organize, and send Proton Mail through the local Proton Bridge, with careful gating for sending and attachment access.

MCP server for reading and searching Proton Mail via Proton Mail Bridge, providing tools to list mailboxes, list/search messages, and get message details with TLS certificate pinning.

Enables an AI agent to discover and call bounded Microsoft 365 tools for reading calendar, mail, Teams channels, SharePoint, and Power Platform metadata through MCP, with synthetic fixtures by default and optional Microsoft Entra/Graph tenant integration.

Official MCP server for Shipmail, enabling agents to manage domains, mailboxes, messages, threads, webhooks, and suppressions via natural language.

Enables AI assistants to interact with Microsoft 365 and Office services through the Microsoft Graph API, providing tools for email, calendar, files, Teams, SharePoint, and more with configurable permissions and output formats.

Enables AI agents to manage Listmonk email campaigns, subscribers, lists, and analytics through typed MCP tools with production safety features.

Enables Claude mobile and claude.ai to access your Spark Desktop mailbox by exposing the official Spark MCP server over authenticated Streamable HTTP, with safety gates for read-only and send permissions.

Enables AI clients to interact with Google services (Gmail, Calendar, Drive, Tasks, YouTube, Contacts) via OAuth-authenticated Cloudflare Workers, allowing actions like sending emails, managing events, and searching files.

Enables AI agents to read a Proton Mail mailbox over IMAP through the official Proton Mail Bridge without any write path, exposing tools to list mailboxes, search messages (umlaut-safe), read threads and emails, and fetch attachments as base64, extracted PDF/OCR text, or rendered images. Also lets agents save attachments into a shared drop folder without the bytes passing through the model.

Enables AI assistants to search, read, label, move, and organize mail and folders through a local Bridge connection, create and manage drafts, and respond to calendar invitations. Ordinary messages are never sent.

Publishes the official kSuite stdio servers as one remote Streamable HTTP endpoint behind an OAuth 2.1 flow that claude.ai custom connectors can complete. Lets each signed-in user enrol their own scoped API token so they can read and act on their mail, calendar, contacts, kChat and kDrive accounts through merged tools.

Enables AI agents to send emails, create drafts in Gmail, and append content to Google Docs via standardized MCP tools.

Enables an LLM client to read and manage email over IMAP/SMTP with read-only mailbox operations and safe, idempotent send/reply, without mutating messages or risking duplicate sends.

Lets Claude Cowork and other remote MCP clients list, search, read, and follow threads in a Tuta Mail account, read-only by default. Opt-in tool groups add moving, trashing, marking, labeling, folder management, and allowlisted plain-text sending, all with server-side caps and an audit log.

Bridges your claude.ai authorized connectors (Slack, Atlassian, Gmail, Google Calendar) to any MCP client, enabling use of those tools without credential setup.

Enables supervised reading, drafting, and sending of email across labeled Gmail, Google Workspace, and Purelymail accounts without a default sender, using explicit delivery authorizations and secure local credential storage.

Exposes news search and top headlines via GNews API, plus simulated email tools for sending and retrieving emails.
