Compatible with every major AI agent and IDE
What is the iCal Calendar Parser MCP Server?
Claude has no access to your local calendar. When you ask 'Do I have any free time tomorrow afternoon?', it simply cannot answer. But if you export your calendar as an .ics file (which every major calendar app supports), this MCP bridges the gap.
This engine uses a robust iCal parser to extract every event with its title, start/end times, location, and attendees into a clean JSON timeline. Sorted chronologically, the AI can instantly find conflicts, identify free slots, and generate weekly summaries of your schedule.
The Superpowers
- Universal Calendar Support: Works with Google Calendar, Apple Calendar, Outlook, and any standard .ics file.
- Chronological Sorting: Events are automatically sorted by start date for timeline clarity.
- Token-Safe: Caps at 200 events to prevent context overflow.
- 100% Air-Gapped Privacy: Your personal schedule stays on your machine.
Built-in capabilities (1)
ics). Provide the absolute file path. Parse a local .ics calendar export (Google Calendar, Apple Calendar, Outlook) into structured JSON events offline

Frequently asked questions
How do I export my Google Calendar?
Go to calendar.google.com > Settings > Import & Export > Export. It downloads a .zip containing .ics files for each calendar.
Can it detect scheduling conflicts?
Yes! Because events are sorted chronologically with start/end times, the AI can easily spot overlapping events and alert you.
Does it include recurring events?
Yes, the parser expands recurring events according to the iCal RRULE specification, so each individual occurrence appears as its own entry.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
