Perplexity

Semantic Search Over Matter Correspondence

The `get_matter_correspondence` tool extracts emails, appointments, and files to feed them directly into your LlamaIndex vector index. This turns your active case history into a searchable knowledge base. Instead of keyword searches, your agent performs semantic queries across all past communication. You get grounded answers based on actual legal facts rather than model hallucinations.

Real-Time Contact Indexing

The `list_cards` tool retrieves your entire firm directory and client list for local indexing. LlamaIndex uses these documents to resolve entity relationships during complex queries. When a client calls, the agent runs `get_card_details` to verify address records and active matters instantly. Keeping this data in your index saves hours of manual searching.

LlamaIndex MCP Server Case Context Synthesis

The `get_matter_details` tool provides the core administrative facts for any active case file. Your LlamaIndex pipeline uses this metadata to filter search results by jurisdiction or matter type. Combining this with `get_matter_linked_cards` lets the agent map out every attorney, witness, and opposing counsel associated with the matter. It builds a complete graph of the case without manual data entry.

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(
