How to Use the Pinterest Ads MCP in LangChain

Q: Can I pass Pinterest Ads analytics data directly into a LangChain prompt?

Yes, you can. The getpinterestanalytics tool returns raw JSON data that your LangChain runnables can format directly into prompt templates. This allows your agent to write performance summaries based on real-time ad spend.

Q: Can a LangChain agent compare different Pinterest Ads audiences?

Absolutely. Your agent can call listpinterestaudiences and parse the target sizes to recommend which segment should receive more budget.

Get real-time Pinterest Ads data directly into your LangChain multi-step reasoning chains using this dedicated MCP server.

Map Pinterest Ads Campaigns in LangChain Chains

The `list_pinterest_campaigns` tool pulls active campaign metrics directly into your LangChain decision loops. Your agent can inspect budget limits and run logic to determine if a campaign needs adjustment based on live performance data. By combining this with other tools in a multi-step chain, your agent checks the campaign status before making any downstream API calls. This MCP integration prevents your pipeline from executing actions on paused or misconfigured ad sets, saving API tokens and execution time.

Run Multi-Step Ad Group Audits via MCP Server

The `list_pinterest_ad_groups` and `list_pinterest_keywords` tools let your LangChain agent audit targeting setups in a single execution pass. The agent fetches the ad groups, extracts the associated keywords, and analyzes them against your target performance metrics. Because LangChain supports observational tracing, you can monitor every step of this analysis in LangSmith. You see exactly how the agent parses the keyword lists and which criteria it uses to flag low-performing targeting blocks.

Automate Creative Analysis in Agent Pipelines

The `list_pinterest_pins` and `get_pinterest_analytics` tools feed raw creative performance data directly into your LangChain LLM prompts. Your agent analyzes which visual assets drive the lowest cost-per-click without requiring manual export steps. This setup feeds performance data from past pins directly into your next content generation prompt. The agent uses actual Pinterest engagement metrics to suggest what creative elements to use in your next campaign cycle.

Setup guide

Set up Pinterest Ads 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 Pinterest Ads 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({
    "pinterest-ads-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 Pinterest Ads transactions"
    })
    print(result["messages"][-1].content)

Common questions about Pinterest Ads MCP in LangChain

LangChain executes tool calls sequentially within your chains, meaning it respects standard API thresholds. If you run large loops over `list_pinterest_campaigns`, you should implement a brief delay between chain steps to prevent hitting Pinterest's rate limits.

Yes, you can. The `get_pinterest_analytics` tool returns raw JSON data that your LangChain runnables can format directly into prompt templates. This allows your agent to write performance summaries based on real-time ad spend.

No, this MCP server is stateless by default. Each tool call like `list_pinterest_ad_groups` runs independently, but you can use LangChain's memory components to keep campaign contexts alive across a conversation.

Absolutely. Your agent can call `list_pinterest_audiences` and parse the target sizes to recommend which segment should receive more budget.

The MCP server runs in an isolated Vinkius sandbox, ensuring your product catalog IDs and pricing data from `list_pinterest_catalogs` never leak. Your developer token is injected at the platform level, so LangChain never exposes your raw credentials in transit.
