MintMCP
MCP ServerFree** - MCP servers for Google Calendar, Gmail, Outlook Calendar, and Outlook.
Capabilities5 decomposed
google calendar event synchronization and management via mcp
Medium confidenceExposes Google Calendar operations through the Model Context Protocol, enabling LLM agents to read, create, update, and delete calendar events by translating natural language intents into authenticated Google Calendar API calls. Uses OAuth 2.0 token-based authentication to establish secure, user-scoped access to calendar data without storing credentials, and implements MCP's tool-calling schema to expose calendar operations as callable functions with structured input/output contracts.
Implements MCP as the integration layer rather than direct REST API exposure, allowing LLM agents to treat calendar operations as native tool calls with automatic schema validation and error handling through the MCP protocol, rather than requiring custom HTTP client logic
Provides tighter LLM integration than raw Google Calendar API SDKs by leveraging MCP's standardized tool-calling interface, reducing boilerplate and enabling multi-provider calendar workflows through a single abstraction
gmail message retrieval and composition via mcp
Medium confidenceExposes Gmail operations through MCP, enabling LLM agents to read, search, and compose emails by translating natural language intents into authenticated Gmail API calls. Implements OAuth 2.0 authentication for secure, user-scoped mailbox access and structures email operations (fetch, search, send, draft) as callable MCP tools with schema-validated inputs for sender, recipient, subject, and body content.
Wraps Gmail API operations in MCP's standardized tool interface, allowing LLM agents to treat email operations as first-class callable functions with automatic schema validation, rather than requiring custom Gmail API client implementations and error handling
Simpler integration path than building custom Gmail API clients; MCP abstraction eliminates boilerplate and enables agents to compose email operations with other tools in a unified execution model
outlook calendar event synchronization and management via mcp
Medium confidenceExposes Microsoft Outlook Calendar operations through MCP, enabling LLM agents to read, create, update, and delete calendar events by translating natural language intents into authenticated Microsoft Graph API calls. Uses OAuth 2.0 with Microsoft identity platform for secure, user-scoped access to Outlook calendars and implements MCP tool-calling schema to expose calendar operations with structured input/output contracts compatible with Microsoft's calendar data model.
Implements MCP integration with Microsoft Graph API rather than legacy Exchange Web Services, providing access to modern Outlook calendar features and multi-tenant support while maintaining compatibility with Azure AD authentication flows
Enables enterprise teams to use Outlook calendars with LLM agents through MCP's standardized interface, avoiding custom Microsoft Graph client implementations and providing better integration with existing Microsoft 365 infrastructure than generic calendar APIs
outlook email message retrieval and composition via mcp
Medium confidenceExposes Microsoft Outlook email operations through MCP, enabling LLM agents to read, search, and compose emails by translating natural language intents into authenticated Microsoft Graph API calls. Implements OAuth 2.0 with Microsoft identity platform for secure, user-scoped mailbox access and structures email operations (fetch, search, send, draft) as callable MCP tools with schema-validated inputs compatible with Outlook's message model.
Integrates with Microsoft Graph API's modern mail endpoints rather than legacy Exchange Web Services, providing access to Outlook's full message model including categories, flags, and advanced search capabilities through MCP's standardized tool interface
Enables enterprise teams to use Outlook email with LLM agents through MCP, avoiding custom Microsoft Graph implementations and providing better integration with Microsoft 365 infrastructure than generic email APIs
multi-provider calendar and email tool orchestration via mcp
Medium confidenceProvides a unified MCP server abstraction that allows LLM agents to interact with multiple calendar and email providers (Google Calendar, Gmail, Outlook Calendar, Outlook Mail) through a single tool interface. Implements provider-agnostic MCP tool schemas that abstract away provider-specific API differences, enabling agents to compose operations across different providers without requiring provider-specific logic or conditional branching.
Implements provider abstraction at the MCP tool level rather than in agent logic, allowing a single set of MCP tools to dispatch to different backends based on provider context, reducing agent complexity and enabling runtime provider selection
Simpler than building provider-specific agents or conditional logic in agent code; MCP abstraction enables teams to support multiple providers with a single tool definition and provider-agnostic agent logic

Known Limitations
- ⚠Requires valid Google OAuth 2.0 credentials and refresh tokens — cannot operate without user authentication
- ⚠Subject to Google Calendar API rate limits (typically 1,000 requests per 100 seconds per user)
- ⚠No built-in conflict detection or intelligent scheduling — returns raw availability data requiring downstream logic
- ⚠Timezone handling depends on calendar configuration; ambiguous timezone specifications may cause scheduling errors
- ⚠Requires Gmail API credentials and OAuth 2.0 user authorization — cannot access mailboxes without explicit user consent
- ⚠Subject to Gmail API rate limits (typically 250 requests per second per user)
