How to Use the DatoCMS MCP in LlamaIndex

Q: How do I set up the DatoCMS MCP Server in LlamaIndex?

Install llama-index-tools-mcp and initialize BasicMCPClient. Convert the tools with McpToolSpec and pass them to your FunctionAgent.

Q: Can LlamaIndex update DatoCMS records?

The agent can call patchcmsrecord to mutate fields. You must explicitly allow this tool if you want your RAG app to write data.

Q: How does LlamaIndex handle DatoCMS GraphQL queries?

You expose executegraphqlcda to the agent. It writes the query based on user prompts and returns the JSON payload for indexing.

Q: Can I restrict which tools the agent uses?

Yes. Use the allowedtools filter when configuring your setup. You might only expose getsinglerecord to prevent accidental deletions.

Index your headless CMS data. LlamaIndex connects to DatoCMS to build semantic search over your live content and media.

RAG Pipelines for DatoCMS in LlamaIndex

Building chatbots over your website content requires fresh data. You use `list_cma_records` to dump your articles into a local vector store. The LlamaIndex agent queries this index instead of hallucinating answers about your company blog. When users ask about specific authors, the query engine hits the index first. If the data looks stale, the agent falls back to `execute_graphql_cda` to fetch the exact node details from the live GraphQL tree.

Indexing Content Models

Your agent needs to understand how your CMS is structured. Running `list_global_models` pulls your entire schema into the LlamaIndex knowledge base. The AI learns exactly which fields belong to which item types. This means the agent constructs perfect queries later. It knows exactly what properties to extract when calling `get_single_record` because the structural rules are already embedded in its context window.

Semantic Search for Media

Finding the right image is usually a manual nightmare. Now you pull every asset's metadata using `list_media_uploads` and vectorize the descriptions. Your users search for concepts, not filenames. Once the query engine finds the match, it retrieves the exact structural block via `get_media_upload`. You serve the correct image URL straight to the user interface via this MCP Server.

Setup guide

Set up DatoCMS MCP in LlamaIndex

Prerequisites

Python 3.10+ installed
llama-index-tools-mcp package
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install llama-index-tools-mcp llama-index-llms-openai. The MCP tools package provides BasicMCPClient and McpToolSpec.
2

Connect with BasicMCPClient
Point BasicMCPClient to your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports SSE and Streamable HTTP transports.
3

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