What is the Lingyi Wanwu MCP Server?
Connect your AI agents to Lingyi Wanwu (01.AI), the high-performance AI lab founded by Dr. Kai-Fu Lee. This MCP provides 10 tools to automate interactions with the Yi series of large language models, including state-of-the-art chat completions, semantic embeddings, and account usage monitoring.
What you can do
- Yi Model Interaction — Trigger chat completions with Yi-34B, Yi-Large, and other optimized models using persistent context
- Vector Embeddings — Generate high-dimensional semantic embeddings to power advanced RAG and search workflows
- Model Intelligence — List all available models and retrieve granular technical specifications for each version
- Account Management — Monitor your token consumption and balance programmatically to optimize costs
How it works
- Subscribe to this server
- Log in to the Lingyi Wanwu Developer Platform
- Navigate to API Keys and generate a new key
- Identify the model you wish to use (e.g.,
yi-largeoryi-34b-chat-0205) - Insert your API Key into the field below to start managing your Yi model workflows.
Who is this for?
- AI Developers — automate the integration of high-performance bilingual (EN/CN) models into custom apps
- Knowledge Engineers — build RAG pipelines using Lingyi Wanwu's optimized embedding services
- System Integrators — bridge enterprise platforms with the efficient and powerful Yi foundation models

Frequently asked questions
Which Yi model is best for complex reasoning?
For complex reasoning and high-quality outputs, yi-large is recommended. For faster response times and cost efficiency, yi-medium or yi-spark are excellent alternatives.
Can I automatically retrieve my remaining account balance?
Yes! Use the get_balance tool. Your agent will connect to the Lingyi Wanwu billing service and return your current remaining credits.
How do I list all the technical specs for the Yi models?
Use the list_models tool. Your agent will retrieve a list of all models currently available on the platform, along with their IDs and capabilities.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
