By the end, you'll have a working Kaleido agent that can list all api keys for your organization, create a new api key for our consortium, show all event streams configured in this environment through natural language commands. This guide will help you understand how to give your LangChain agent real control over a Kaleido account through Composio's Kaleido MCP server. Before we dive in, let's take a quick look at the key ideas and tools involved. ## Also integrate Kaleido with - [OpenAI Agents SDK](https://composio.dev/toolkits/kaleido/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/kaleido/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/kaleido/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/kaleido/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/kaleido/framework/codex) - [OpenClaw](https://composio.dev/toolkits/kaleido/framework/openclaw) - [Hermes](https://composio.dev/toolkits/kaleido/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/kaleido/framework/cli) - [Google ADK](https://composio.dev/toolkits/kaleido/framework/google-adk) - [Vercel AI SDK](https://composio.dev/toolkits/kaleido/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/kaleido/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/kaleido/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/kaleido/framework/crew-ai) ## TL;DR Here's what you'll learn: - Get and set up your OpenAI and Composio API keys - Connect your Kaleido project to Composio - Create a Tool Router MCP session for Kaleido - Initialize an MCP client and retrieve Kaleido tools - Build a LangChain agent that can interact with Kaleido - Set up an interactive chat interface for testing ## What is LangChain? LangChain is a framework for developing applications powered by language models. It provides tools and abstractions for building agents that can reason, use tools, and maintain conversation context. Key features include: - Agent Framework: Build agents that can use tools and make decisions - MCP Integration: Connect to external services through Model Context Protocol adapters - Memory Management: Maintain conversation history across interactions - Multi-Provider Support: Works with OpenAI, Anthropic, and other LLM providers ## What is the Kaleido MCP server, and what's possible with it? The Kaleido MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Kaleido account. It provides structured and secure access to your blockchain environment, so your agent can perform actions like managing organizations, handling API keys, retrieving memberships, and monitoring event streams on your behalf. - Organization and consortium management: Let your agent list, retrieve, and manage organizations and consortia that you have access to—making it easy to keep your blockchain networks organized. - API key lifecycle control: Effortlessly create, retrieve, and delete API keys for your organization, so you can handle credential management without manual steps. - Membership and access insights: Quickly fetch details about user memberships and organizational access, helping you stay on top of roles and permissions in your blockchain environment. - Event stream monitoring: Retrieve and review all event streams configured in your environment, making it simple to keep tabs on real-time blockchain activity. - App2App and credential retrieval: Ask your agent to list App2App runtimes and fetch application credentials for specific environments, streamlining application integration and deployment. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `KALEIDO_ADD_IDENTITY_PROOF` | Add Organization Identity Proof | Add an x509 identity proof to a Kaleido organization.

It provides structured and secure access so your agent can perform Kaleido operations on your behalf through a secure, permission-based interface. With Composio's managed implementation, you don't have to create your own developer app. For production, if you're building an end product, we recommend using your own credentials. The managed server helps you prototype fast and go from 0-1 faster. ## Step-by-step Guide ### 1. Prerequisites No description provided. ### 1. Getting API Keys for OpenAI and Composio OpenAI API Key - Go to the [OpenAI dashboard](https://platform.openai.com/settings/organization/api-keys) and create an API key. You'll need credits to use the models, or you can connect to another model provider. - Keep the API key safe. Composio API Key - Log in to the [Composio dashboard](https://dashboard.composio.dev?utm_source=toolkits&utm_medium=framework_docs). - Navigate to your API settings and generate a new API key. - Store this key securely as you'll need it for authentication. ### 2. Install dependencies No description provided. ```python pip install composio-langchain langchain-mcp-adapters langchain python-dotenv ``` ```typescript npm install @composio/langchain @langchain/core @langchain/openai @langchain/mcp-adapters dotenv ``` ### 3. Set up environment variables Create a .env file in your project root. What's happening: - COMPOSIO_API_KEY authenticates your requests to Composio's API - COMPOSIO_USER_ID identifies the user for session management - OPENAI_API_KEY enables access to OpenAI's language models ```bash COMPOSIO_API_KEY=your_composio_api_key_here COMPOSIO_USER_ID=your_composio_user_id_here OPENAI_API_KEY=your_openai_api_key_here ``` ### 4. Import dependencies No description provided. ```python from langchain_mcp_adapters.client import MultiServerMCPClient from langchain.agents import create_agent from dotenv import load_dotenv from composio import Composio import asyncio import os load_dotenv() ``` ```typescript import { Composio } from '@composio/core'; import { LangchainProvider } from '@composio/langchain'; import { MultiServerMCPClient } from "@langchain/mcp-adapters"; import { createAgent } from "langchain"; import * as readline from 'readline'; import 'dotenv/config'; dotenv.config(); ``` ### 5. Initialize Composio client What's happening: - We're loading the COMPOSIO_API_KEY from environment variables and validating it exists - Creating a Composio instance that will manage our connection to Kaleido tools - Validating that COMPOSIO_USER_ID is also set before proceeding ```python async def main(): composio = Composio(api_key=os.getenv("COMPOSIO_API_KEY")) if not os.getenv("COMPOSIO_API_KEY"): raise ValueError("COMPOSIO_API_KEY is not set") if not os.getenv("COMPOSIO_USER_ID"): raise ValueError("COMPOSIO_USER_ID is not set") ``` ```typescript const composioApiKey = process.env.COMPOSIO_API_KEY; const userId = process.env.COMPOSIO_USER_ID; if (!composioApiKey) throw new Error('COMPOSIO_API_KEY is not set'); if (!userId) throw new Error('COMPOSIO_USER_ID is not set'); async function main() { const composio = new Composio({ apiKey: composioApiKey as string, provider: new LangchainProvider() }); ``` ### 6. Create a Tool Router session What's happening: - We're creating a Tool Router session that gives your agent access to Kaleido tools - The create method takes the user ID and specifies which toolkits should be available - The returned session.mcp.url is the MCP server URL that your agent will use - This approach allows the agent to dynamically load and use Kaleido tools as needed ```python # Create Tool Router session for Kaleido session = composio.create( user_id=os.getenv("COMPOSIO_USER_ID"), toolkits=['kaleido'] ) url = session.mcp.url ``` ```typescript const session = await composio.create( userId as string, { toolkits: ['kaleido'] } ); const url = session.mcp.url; ``` ### 7. Configure the agent with the MCP URL No description provided. ```python client = MultiServerMCPClient({ "kaleido-agent": { "transport": "streamable_http", "url": session.mcp.url, "headers": { "x-api-key": os.getenv("COMPOSIO_API_KEY") } } }) tools = await client.get_tools() agent = create_agent("gpt-5", tools) ``` ```typescript const client = new MultiServerMCPClient({ "kaleido-agent": { transport: "http", url: url, headers: { "x-api-key": process.env.COMPOSIO_API_KEY } } }); const tools = await client.getTools(); const agent = createAgent({ model: "gpt-5", tools }); ``` ### 8. Set up interactive chat interface No description provided. ```python conversation_history = [] print("Chat started! Type 'exit' or 'quit' to end the conversation.\n") print("Ask any Kaleido related question or task to the agent.\n") while True: user_input = input("You: ").strip() if user_input.lower() in ['exit', 'quit', 'bye']: print("\nGoodbye!") break if not user_input: continue conversation_history.append({"role": "user", "content": user_input}) print("\nAgent is thinking...\n") response = await agent.ainvoke({"messages": conversation_history}) conversation_history = response['messages'] final_response = response['messages'][-1].content print(f"Agent: {final_response}\n") ``` ```typescript let conversationHistory: any[] = []; console.log("Chat started! Type 'exit' or 'quit' to end the conversation.\n"); console.log("Ask any Kaleido related question or task to the agent.\n"); const rl = readline.createInterface({ input: process.stdin, output: process.stdout, prompt: 'You: ' }); rl.prompt(); rl.on('line', async (userInput: string) => { const trimmedInput = userInput.trim(); if (['exit', 'quit', 'bye'].includes(trimmedInput.toLowerCase())) { console.log("\nGoodbye!"); rl.close(); process.exit(0); } if (!trimmedInput) { rl.prompt(); return; } conversationHistory.push({ role: "user", content: trimmedInput }); console.log("\nAgent is thinking...\n"); const response = await agent.invoke({ messages: conversationHistory }); conversationHistory = response.messages; const finalResponse = response.messages[response.messages.length - 1]?.content; console.log(`Agent: ${finalResponse}\n`); rl.prompt(); }); rl.on('close', () => { console.log('\n👋 Session ended.'); process.exit(0); }); ``` ### 9. Run the application No description provided. ```python if __name__ == "__main__": asyncio.run(main()) ``` ```typescript main().catch((err) => { console.error('Fatal error:', err); process.exit(1); }); ``` ## Complete Code ```python from langchain_mcp_adapters.client import MultiServerMCPClient from langchain.agents import create_agent from dotenv import load_dotenv from composio import Composio import asyncio import os load_dotenv() async def main(): composio = Composio(api_key=os.getenv("COMPOSIO_API_KEY")) if not os.getenv("COMPOSIO_API_KEY"): raise ValueError("COMPOSIO_API_KEY is not set") if not os.getenv("COMPOSIO_USER_ID"): raise ValueError("COMPOSIO_USER_ID is not set") session = composio.create( user_id=os.getenv("COMPOSIO_USER_ID"), toolkits=['kaleido'] ) url = session.mcp.url client = MultiServerMCPClient({ "kaleido-agent": { "transport": "streamable_http", "url": url, "headers": { "x-api-key": os.getenv("COMPOSIO_API_KEY") } } }) tools = await client.get_tools() agent = create_agent("gpt-5", tools) conversation_history = [] print("Chat started! Type 'exit' or 'quit' to end the conversation.\n") print("Ask any Kaleido related question or task to the agent.\n") while True: user_input = input("You: ").strip() if user_input.lower() in ['exit', 'quit', 'bye']: print("\nGoodbye!") break if not user_input: continue conversation_history.append({"role": "user", "content": user_input}) print("\nAgent is thinking...\n") response = await agent.ainvoke({"messages": conversation_history}) conversation_history = response['messages'] final_response = response['messages'][-1].content print(f"Agent: {final_response}\n") if __name__ == "__main__": asyncio.run(main()) ``` ```typescript import { Composio } from '@composio/core'; import { LangchainProvider } from '@composio/langchain'; import { MultiServerMCPClient } from "@langchain/mcp-adapters"; import { createAgent } from "langchain"; import * as readline from 'readline'; import 'dotenv/config'; const composioApiKey = process.env.COMPOSIO_API_KEY; const userId = process.env.COMPOSIO_USER_ID; if (!composioApiKey) throw new Error('COMPOSIO_API_KEY is not set'); if (!userId) throw new Error('COMPOSIO_USER_ID is not set'); async function main() { const composio = new Composio({ apiKey: composioApiKey as string, provider: new LangchainProvider() }); const session = await composio.create( userId as string, { toolkits: ['kaleido'] } ); const url = session.mcp.url; const client = new MultiServerMCPClient({ "kaleido-agent": { transport: "http", url: url, headers: { "x-api-key": process.env.COMPOSIO_API_KEY } } }); const tools = await client.getTools(); const agent = createAgent({ model: "gpt-5", tools }); let conversationHistory: any[] = []; console.log("Chat started! Type 'exit' or 'quit' to end the conversation.\n"); console.log("Ask any Kaleido related question or task to the agent.\n"); const rl = readline.createInterface({ input: process.stdin, output: process.stdout, prompt: 'You: ' }); rl.prompt(); rl.on('line', async (userInput: string) => { const trimmedInput = userInput.trim(); if (['exit', 'quit', 'bye'].includes(trimmedInput.toLowerCase())) { console.log("\nGoodbye!"); rl.close(); process.exit(0); } if (!trimmedInput) { rl.prompt(); return; } conversationHistory.push({ role: "user", content: trimmedInput }); console.log("\nAgent is thinking...\n"); const response = await agent.invoke({ messages: conversationHistory }); conversationHistory = response.messages; const finalResponse = response.messages[response.messages.length - 1]?.content; console.log(`Agent: ${finalResponse}\n`); rl.prompt(); }); rl.on('close', () => { console.log('\nSession ended.'); process.exit(0); }); } main().catch((err) => { console.error('Fatal error:', err); process.exit(1); }); ``` ## Conclusion You've successfully built a LangChain agent that can interact with Kaleido through Composio's Tool Router. Key features of this implementation: - Dynamic tool loading through Composio's Tool Router - Conversation history maintenance for context-aware responses - Async Python provides clean, efficient execution of agent workflows You can extend this further by adding error handling, implementing specific business logic, or integrating additional Composio toolkits to create multi-app workflows. ## How to build Kaleido MCP Agent with another framework - [OpenAI Agents SDK](https://composio.dev/toolkits/kaleido/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/kaleido/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/kaleido/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/kaleido/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/kaleido/framework/codex) - [OpenClaw](https://composio.dev/toolkits/kaleido/framework/openclaw) - [Hermes](https://composio.dev/toolkits/kaleido/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/kaleido/framework/cli) - [Google ADK](https://composio.dev/toolkits/kaleido/framework/google-adk) - [Vercel AI SDK](https://composio.dev/toolkits/kaleido/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/kaleido/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/kaleido/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/kaleido/framework/crew-ai) ## Related Toolkits - [Supabase](https://composio.dev/toolkits/supabase) - Supabase is an open-source backend platform offering scalable Postgres databases, authentication, storage, and real-time APIs.

With a standalone Kaleido MCP server, the agents and LLMs can only access a fixed set of Kaleido tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Kaleido and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with LangChain? Yes, you can. LangChain fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Kaleido tools. ### Can I manage the permissions and scopes for Kaleido while using Tool Router? Yes, absolutely. You can configure which Kaleido scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do. ### How safe is my data with Composio Tool Router? All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Kaleido data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
