How to Use the DatoCMS MCP in LangChain

Q: How do I connect DatoCMS to LangChain?

Use MultiServerMCPClient with your Vinkius MCP endpoint. Pass the resulting tools directly into createagent.

Q: Can LangChain agents query the DatoCMS GraphQL API?

Yes. The executegraphqlcda tool lets your agent write and run raw GraphQL queries against your content tree.

Q: What happens if a LangChain agent deletes a DatoCMS record?

Calling wipecmsrecord permanently drops the node from your active document rows. You cannot undo this action.

Build headless content pipelines in LangChain. Connect DatoCMS to your agents for automated publishing and GraphQL queries.

DatoCMS MCP Server in ReAct Agents

Your LangChain agent needs to pull live content, modify it, and push it back. This server exposes `list_cma_records` so the agent finds outdated posts immediately. The script reviews the text and fires `patch_cms_record` to update the fields without human intervention. You get full observability in LangSmith. Every GraphQL query sent through `execute_graphql_cda` shows up in your traces. You know exactly how many tokens the agent burned while fetching media IDs.

Chain Content Creation Workflows

Stop writing glue code for your CMS. You build a pipeline where a researcher agent drafts text and passes it to a publisher agent. That final step triggers `create_cms_record` to push the JSON payload straight into your headless architecture. Errors get caught in the chain. If the payload fails validation, the agent reads the error, corrects the schema using `list_global_models` for reference, and retries the insertion.

Automated Media Audits

LangChain can iterate through your asset library. You set up a loop that calls `list_media_uploads` to grab everything in your cloud storage. The agent checks file metadata against your internal rules. When it finds orphaned images, it doesn't just flag them. The script executes `wipe_media_upload` to drop the files from disk. Your storage stays clean without manual intervention.

Setup guide

Set up DatoCMS MCP in LangChain

Prerequisites

Python 3.10+ installed
langchain-mcp-adapters + langgraph packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install langchain-mcp-adapters langgraph langchain-openai. The MCP adapters package converts MCP tools into native LangChain BaseTool objects.
2

Connect via HTTP transport
Use MultiServerMCPClient with "transport": "http" pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create a ReAct agent
Pass the discovered tools to create_react_agent() from LangGraph. The agent automatically routes DatoCMS tool calls through the MCP protocol.
4

Run with any LLM
Swap ChatOpenAI for ChatAnthropic, ChatGoogleGenerativeAI, or any LangChain-compatible model. The MCP tools work identically across all providers.

agent.py

from langchain_mcp_adapters.client import MultiServerMCPClient
from langgraph.prebuilt import create_react_agent
from langchain_openai import ChatOpenAI

async with MultiServerMCPClient({
    "datocms-mcp": {
        "transport": "http",
        "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp",
    }
}) as client:
    tools = client.get_tools()

    agent = create_react_agent(
        ChatOpenAI(model="gpt-4o"),
        tools,
    )
    result = await agent.ainvoke({
        "messages": "List recent DatoCMS transactions"
    })
    print(result["messages"][-1].content)
