Perplexity

Knowledge-augmented scheduling

Transform static .ics files into a searchable knowledge base. Use `parse_ical_calendar` to extract events and index them directly into your vector store. Your LlamaIndex agent can now answer questions about your history. Ask it when you last met a specific person or how many hours you spent in meetings last month.

Semantic calendar querying

Combine raw API data with your existing documents. `parse_ical_calendar` provides the structured output needed to ground your agent in reality. Stop guessing your availability. The agent queries the index to find gaps based on actual event data rather than relying on stale summaries.

Unified data access

Include calendar data in your RAG pipeline without complex ETL jobs. The MCP server acts as a bridge between your local calendar files and the LlamaIndex query engine. It treats your calendar like any other document. You get a single, unified view of your professional and personal information.

Convert to LlamaIndex tools
Call mcp_tool_spec.to_tool_list_async() to convert all iCal Calendar Parser MCP tools into native FunctionTool objects that any LlamaIndex agent can use.
4

Run with any LLM
Create a FunctionAgent with the tools and your preferred LLM. Swap OpenAI for Anthropic, Gemini, or any LlamaIndex-supported provider.

agent.py

from llama_index.tools.mcp import BasicMCPClient, McpToolSpec
from llama_index.core.agent.workflow import FunctionAgent
from llama_index.llms.openai import OpenAI

# Connect to the MCP
mcp_client = BasicMCPClient(
    "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)
mcp_tool_spec = McpToolSpec(client=mcp_client)

# Convert MCP tools to LlamaIndex tools
tools = await mcp_tool_spec.to_tool_list_async()

# Create and run the agent
agent = FunctionAgent(
    tools=tools,
    llm=OpenAI(model="gpt-4o"),
    system_prompt="You have access to iCal Calendar Parser tools.",
)
response = await agent.run("List recent iCal Calendar Parser data")

Common questions about iCal Calendar Parser MCP in LlamaIndex

Use the `McpToolSpec` class to wrap the server tools. Once registered, you can pass them to your agent and start indexing your calendar events.

Yes, you can index multiple files sequentially. LlamaIndex merges the data into a single vector space for cross-calendar analysis.

It is designed for exactly that. The tool output is formatted to be ingested by your indexer, making your schedule searchable via natural language.

The parser handles standard calendar exports comfortably. Performance remains high as long as your system memory can hold the JSON representation.

The server operates entirely offline on your local machine. No calendar metadata ever leaves your infrastructure during the indexing process.
