And MCP makes the experience even better. With Kaleido MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer. ## 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) - [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) - [LangChain](https://composio.dev/toolkits/kaleido/framework/langchain) - [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 ### Why use Composio? Apart from a managed and hosted MCP server, you will get: - CodeAct: A dedicated workbench that allows GPT to write its code to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling. - Large tool responses: Handle them to minimise context rot. - Dynamic just-in-time access to 20,000 tools across 1000+ other Apps for cross-app workflows. It loads the tools you need, so GPTs aren't overwhelmed by tools you don't need. ## Connect Kaleido to Codex ### How to install Kaleido MCP in Codex ### Run the setup command Run this command in your terminal to add the Composio MCP server to Codex. ```bash codex mcp add composio --url https://connect.composio.dev/mcp ``` ## 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. Use this to register a certificate chain that links an organization's off-chain PKI identity to their blockchain accounts. The certificate will be in 'pending' state until verified. | | `KALEIDO_CREATE_API_KEY` | Create API Key | Creates a new API key for the specified Kaleido organization. The returned apikey secret should be stored securely as it cannot be retrieved again. Use KALEIDO_GET_ORGANIZATIONS to obtain a valid org_id first. Note: Organizations have a limit on active API keys (e.g., 5 for starter plans). | | `KALEIDO_DELETE_API_KEY` | Delete API Key | Permanently deletes an API key by its ID. First use 'Get API Keys' to retrieve the list of API keys and their IDs. The deletion is irreversible. | | `KALEIDO_DELETE_ORGANIZATION_IDENTITY_PROOF` | Delete Organization Identity Proof | Remove an x509 identity proof from a Kaleido organization. This permanently deletes the identity proof. The deletion is irreversible. | | `KALEIDO_GET_API_KEY` | Get API Key | Tool to retrieve details of a specific API key by its ID. Use when you need to get information about a particular API key after obtaining its ID from the Get API Keys action. | | `KALEIDO_GET_API_KEYS` | Get API Keys | Tool to retrieve all API keys associated with the organization.

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 Codex? Yes, you can. Codex 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)
