How to Use the AppGallery Connect MCP in LangChain

Q: Does this MCP server support multiple apps in LangChain?

Yes, use listapps to retrieve all your IDs. You then pass the specific ID to other tools to target the correct project.

Automated app submission in LangChain

Your agent handles the full release cycle by chaining `get_submission_status` with `submit_for_review`. It waits for the binary to pass validation before pushing the final build. This workflow removes manual oversight. The agent triggers the next link in your chain only after the previous status check returns a green light.

Review management via LangChain agents

Agents pull recent feedback using `get_comments` to identify common user complaints. It then filters these by language using `get_app_language_info` for targeted analysis. You can feed this data into a summarization chain. Once the agent identifies a trend, it uses `reply_to_comment` to issue a response without you touching the console.

Performance tracking for LangChain workflows

Track your install and download velocity by piping `get_download_stats` and `get_install_stats` into LangSmith. You get exact numbers on how your latest update performs. The MCP server feeds raw data directly into your monitoring chain. You see exactly when a release drops by watching the spikes in your custom dashboard.

Setup guide

Set up AppGallery Connect 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 AppGallery Connect 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({
    "appgallery-connect-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 AppGallery Connect transactions"
    })
    print(result["messages"][-1].content)
