Build smarter reasoning chains with LangChain and Cohere (AI Platform)

Exposing `chat_generation` and `generate_text` as tools, this MCP integration lets your LangChain agents decide when to run conversational transformations on the fly. Instead of hardcoding your LLM calls, you let the agent evaluate the current chain state and hit the correct generation endpoint when needed. Every tool call is fully observable. You can track latency and token usage in LangSmith while your agent runs `list_models` to check available models before routing the prompt payload to the best fit.

Reorder and classify documents in active pipelines

Exposing `rerank_documents` and `classify_inputs` as tools, this server lets you clean up your context window by reordering search results inside your LangChain chains. You can strip out noisy data before sending the final context to the model, saving money and improving accuracy. Using this MCP Server, your agent can also tag incoming user messages. This keeps your routing logic clean without writing custom classification code.

Tokenize and embed text inside your LangChain agents

By exposing `tokenize_text` and `generate_embeddings`, this server lets your LangChain agents manage token budgets and generate vectors programmatically. The agent checks the exact size of a text block before sending it, avoiding unexpected rate limit errors during execution. When your pipeline requires vector representations, the agent triggers the embedding tool. This gives your chains native access to Cohere's vector space without leaving the execution loop.

Setup guide

Set up Cohere (AI Platform) 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 Cohere (AI Platform) 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({
    "cohere-ai-platform-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 Cohere (AI Platform) transactions"
    })
    print(result["messages"][-1].content)

Common questions about Cohere (AI Platform) MCP in LangChain

Install the langchain-mcp-adapters package and initialize the MultiServerMCPClient. Call get_tools to grab the toolset, then pass that list directly to your LangChain agent constructor.

Yes, every tool call is automatically tracked. LangSmith captures the exact inputs, outputs, and latency for tools like chat_generation or rerank_documents so you can debug your chain performance in real time.

The connection is stateless by default to keep your chains lightweight. If you need to maintain persistent context across multiple steps, call client.session to spin up a dedicated session for your agent.

This server lets your agent dynamically discover and invoke tools on demand. Instead of hardcoding API calls, your LangChain agent decides which tool to run based on the current chain state.

Yes, Vinkius runs the server in an isolated, zero-trust environment. Your Cohere API key and prompt text are never stored on disk, and all communication travels over secure, ephemeral channels.
