"Proton Mail" matching MCP servers:

Enables interaction with Proton Pass via CLI operations, including vault and item management, secret injection, and password generation.

A read-only MCP server that lets ChatGPT search and read a Proton Mail account through Proton Mail Bridge. It provides mailbox listing, mail search, and single-message retrieval without the ability to send, modify, or delete email.

A lightweight MCP server providing AI agents a scoped, read-and-draft-only view into Proton Mail via Proton Bridge, with code-enforced restrictions preventing external access or sending.

A security-first MCP server that provides AI agents with a scoped, read-and-draft-only view into Proton Mail via Proton Bridge, ensuring no emails can be sent and access is restricted to configured workspaces.

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.

Enables auditing any domain's email deliverability and DNS health, including SPF, DKIM, DMARC, MX, mail provider, DNS blacklist status, catch-all, domain age, and a deliverability score.

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.

An MCP server that gives AI agents permission-gated, audit-logged access to private email providers (Proton Mail via Bridge and plain IMAP), running locally with OAuth-based authentication and human-controlled escalation for destructive operations.

Local-first Gmail MCP server using PKCE + loopback OAuth flow that stores refresh tokens in the OS keychain, enabling secure read/write Gmail access via MCP tools without tokens leaving the device.

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.

A Model Context Protocol (MCP) server for Proton Pass. It wraps the official pass-cli binary and exposes 14 tools so any MCP-compatible AI assistant (Claude Desktop, Claude Code, etc.) can manage your vaults, credentials, and secrets.

Enables AI assistants to perform detailed DNS reconnaissance through natural language requests. Retrieves comprehensive DNS record information including subdomains, mail servers, and DNS infrastructure details using the DNSDumpster API.

Enables agentic administration of Infomaniak accounts via Claude, offering 169 tools for web hosting, mail, domains, DNS, and more, with a strict two-phase commit for safe mutations.

Adds a responsible-AI safety layer to any agent by exposing RAIL Score's evaluation, agent-guardrail, and compliance capabilities as MCP tools, enabling content scoring, injection detection, tool call evaluation, and DPDP compliance checks.

Gives MCP clients access to a Mail.ru mailbox for reading, searching, and filtering messages, creating folders, moving, archiving, and deleting mail, and preparing or sending replies, with mass operations preceded by dry runs and deletions kept reversible. It also handles Mail.ru-specific quirks such as modified UTF-7 folder names and dropped long IMAP sessions, and restricts sending to an allowlist of recipients.

A privacy-focused MCP server that grants Claude read-only access to Gmail using strict, user-defined filters to control which emails are exposed. It enables searching and fetching email metadata while ensuring data security through OAuth and localized filter enforcement.

An open-source MCP server that provides AI agents with secure access to read, search, and manage emails via Microsoft 365 and Gmail. It features security-first defaults like recipient allowlists and markdown content conversion to facilitate safe agent interaction with mailboxes.

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.

Enables Windows-native malware analysis and reverse engineering inside Flare-VM by exposing 50 tools for static and dynamic analysis, memory injection scanning, debugging, network simulation, and automated triage playbooks without requiring a Kali Linux host, WinRM, or SMB shares.

Enables AI agents to read, send, and reply to GPG-encrypted email over IMAP/SMTP, manage a contact book with key provenance, and archive and search everything read. Key material and message bodies are kept out of the model's context window, with encryption enforced by default.
