"Proton Calendar" matching MCP servers:

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

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.

Enables AI assistants to read, create, update, move, and delete calendar events, list calendars, and query free/busy across multiple independent Google accounts through a single interface, with each account routed explicitly and gated by role-based access control. It also includes a built-in personal time-management assistant and stores each account's OAuth tokens in a local encrypted vault.

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 secure enterprise AI agents to access internal tools like GitHub, Gmail, Calendar, file systems, databases, and knowledge bases through the Model Context Protocol, with built-in security, audit, and observability.

Permission gateway that hands an AI agent a scoped MCP endpoint instead of an OAuth token: connect 27 services (Gmail, Google Calendar/Drive/Ads/Search Console, Slack, Notion, GitHub, Jira, Salesforce, HubSpot, Stripe, LinkedIn, X, Meta Ads and more), grant per-action permissions finer than native OAuth scopes, audit every call and revoke a key in one click. Self-hostable, MIT.

Enables AI clients to interact with ProtonMail accounts through the Proton Bridge using SMTP and IMAP protocols. Provides email management capabilities via secure local bridge connections.

Enables MCP-aware AI clients to call AgentDraft's per-agent inbox, conflict-free calendar booking, and tamper-evident audit trail as tools.

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.

Enables MCP clients to authenticate with Google OAuth and securely access Google Calendar's official MCP server without exposing the Google client secret.

Self-hosted MCP server that filters sensitive data from email and calendar before it reaches AI assistants, masking or withholding confidential content based on user policy.

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.

Demonstrates OAuth 2.0 Dynamic Client Registration with Duo SSO, providing three MCP servers for calendar events, document management, and analytics dashboards.

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.

Enables invited ChatGPT accounts to reach the Sense family calendar and reminder service through an OAuth-protected AWS gateway without exposing the underlying Sense API key. It exposes six read tools plus six optional write tools for events and reminders, with all destructive and administrative actions blocked.
