Ground LlamaIndex queries with Claude

Use `send_message` to pull live data and pipe it straight into your vector store. Your index stays current because the agent pulls the latest model responses on demand. This creates a feedback loop where your knowledge base grows as you talk to the model. It moves beyond static documents into dynamic, API-driven intelligence.

Discover models for LlamaIndex indexing

Run `list_models` to see exactly what Claude versions are available for your current task. You can filter by capabilities to ensure your index uses the right model for the job. It removes the guesswork from setting up your RAG pipelines. You get a clean list of IDs ready for immediate assignment in your agent specs.

Manage Claude API costs in LlamaIndex

Check your token usage with `count_tokens` before indexing large chunks of text. It saves you from blowing through your budget on unnecessary API calls. Getting a hard count before you commit to a query helps maintain a efficient, cost-effective search index. It turns vague estimates into exact planning.

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