"calendar" matching MCP servers:

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.

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

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

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.

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.

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

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.
