Manage Case Lifecycle

You need to log a new customer issue? Use `zoho_create_case` to open a record with required details like subject, priority, and origin channel. If the case status changes—say, it's resolved—you can update it using `zoho_update_case`, ensuring the proper process flow is recorded. This capability lets your agent build a full customer journey chain: search for an existing issue with `zoho_search_cases`, then escalate or close it by calling `zoho_update_case`. It keeps the entire support workflow visible in one sequence.

Build Knowledge Base Pipelines

Need to document a new solution? Start by creating an article using `zoho_create_solution`, providing title, question, and answer. Later, if you want your agent to check existing documentation before generating anything, it can call `zoho_search_solutions`. This allows you to chain together knowledge retrieval and content creation. An initial query hits `zoho_search_solutions`; if nothing matches, the agent proceeds to use `zoho_create_solution`.

Audit Support Records

Check on open support issues or review documentation status using the MCP Server. You can list all current cases via `zoho_list_cases`, giving you a quick overview of owner and priority. Alternatively, if your agent needs to verify what's published, it can use `zoho_list_solutions` to pull down the title and publish status of existing knowledge base articles. It makes auditing simple.

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

Pass the discovered tools to create_react_agent() from LangGraph. The agent automatically routes Zoho CRM Service 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.
