How to Use the Codacy MCP in LangChain

Q: How do I add the Codacy MCP Server to my LangChain agent?

Install langchain-mcp-adapters and use the MultiServerMCPClient pointing to the Vinkius endpoint. Pass the tools directly to your agent executor to start analyzing repositories.

Q: Can a LangChain agent automatically flag Codacy issues in a repository?

Yes. The agent runs searchrepositoryissues to find flaws, then passes that data to the next chain step to notify developers.

Q: Does LangChain support tracing for Codacy MCP Server tool calls?

Yes, every call to getrepositoryqualityanalysis or other tools shows up in LangSmith. You get full visibility into latency and token usage for each run.

Q: Can I query multiple organizations at once?

You can. The agent calls listcodacyorganizations first, loops through each organization, and gathers repository lists in a single run.

Run LangChain pipelines with this MCP server to pull live Codacy quality metrics and trigger reviews without leaving your prompt.

Automate quality gates in LangChain

Feed the output of `get_repository_quality_analysis` directly into your chain to stop manually checking pull requests for style violations. Your agent blocks merges when grade thresholds drop based on actual code health. Configure the chain to run `search_repository_issues` right after a run. If new issues pop up, the agent routes them to the right team members using `list_organization_members` in a single execution flow.

Trace Codacy MCP Server runs in LangSmith

Track every execution when your agent calls `list_organization_repositories` or `list_supported_languages` in LangSmith. You see the exact latency and token cost for every single repository audit. This deep visibility means you debug failing tool calls instantly. When a team adds a new project, you trace how the agent resolves repository settings without guessing what went wrong in the background.

Audit team access on the fly

Call `list_codacy_organizations` to map out your teams, then pull membership lists with `list_organization_members` in one run. You combine different data sources without writing custom scripts. The output flows directly into your database or alerting tools. Your LangChain agent handles the transition between these API calls natively.

Setup guide

Set up Codacy 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 Codacy 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({
    "codacy-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 Codacy transactions"
    })
    print(result["messages"][-1].content)
