Perplexity

Turn search results into knowledge

Use `search_articles` to pull data and ingest it into your vector index. Your RAG system then queries this information to answer complex questions about research. This turns transient API results into a persistent knowledge base. You stop relying on model training data and start using live, verified publications.

Ground your agent with Europe PMC

Your agent checks the index created from `get_article_fields` before generating responses. This ensures the agent uses the correct terminology and metadata fields. It prevents the agent from making up facts about funding or paper citations. You get answers that actually cite the sources found in the database.

Filter data with MCP controls

Apply filters to your tool list so your agent only accesses what you permit. You can restrict the agent to specific grant types or article categories. This keeps your index clean and focused on your research goals. It prevents the agent from wasting cycles on irrelevant data.

Convert to LlamaIndex tools
Call mcp_tool_spec.to_tool_list_async() to convert all Europe PMC 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 Europe PMC tools.",
)
response = await agent.run("List recent Europe PMC data")
