And MCP makes the experience even better. With RudderStack Transformation MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer. ## Also integrate RudderStack Transformation with - [OpenAI Agents SDK](https://composio.dev/toolkits/rudderstack_transformation/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/rudderstack_transformation/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/rudderstack_transformation/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/rudderstack_transformation/framework/claude-cowork) - [OpenClaw](https://composio.dev/toolkits/rudderstack_transformation/framework/openclaw) - [Hermes](https://composio.dev/toolkits/rudderstack_transformation/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/rudderstack_transformation/framework/cli) - [Google ADK](https://composio.dev/toolkits/rudderstack_transformation/framework/google-adk) - [LangChain](https://composio.dev/toolkits/rudderstack_transformation/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/rudderstack_transformation/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/rudderstack_transformation/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/rudderstack_transformation/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/rudderstack_transformation/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 RudderStack Transformation to Codex ### How to install RudderStack Transformation 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 RudderStack Transformation MCP server, and what's possible with it? The RudderStack Transformation MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your RudderStack Transformation account. It provides structured and secure access so your agent can perform RudderStack Transformation operations on your behalf. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `RUDDERSTACK_TRANSFORMATION_CREATE_LIBRARY` | Create Library | Tool to create a library in RudderStack Transformation. Use when you need to create reusable JavaScript or Python code that can be imported in transformations. Libraries enable code reusability and version maintenance. | | `RUDDERSTACK_TRANSFORMATION_CREATE_TRANSFORMATION` | Create Transformation | Tool to create a RudderStack transformation. When publish=false (default), creates an unpublished transformation not available to event traffic. When publish=true, publishes the transformation making it live for incoming events and connectable to destinations. | | `RUDDERSTACK_TRANSFORMATION_DELETE_TRANSFORMATION` | Delete Transformation | Delete a published transformation by ID. Note that RudderStack never deletes a transformation revision. Use this when you need to remove a transformation from the system. | | `RUDDERSTACK_TRANSFORMATION_GET_LIBRARY` | Get library by ID | Retrieves a single published library by its unique identifier. Use when you need to fetch details of a specific library. | | `RUDDERSTACK_TRANSFORMATION_GET_LIBRARY_VERSION` | Get Library Version | Tool to retrieve a single library version by library ID and version ID. Use when you need to fetch details of a specific library revision in RudderStack transformations. | | `RUDDERSTACK_TRANSFORMATION_GET_TRANSFORMATION` | Get Transformation | Tool to retrieve a published transformation by its ID from RudderStack. Use when you need to fetch details about a specific transformation including its code, version, and associated destinations. | | `RUDDERSTACK_TRANSFORMATION_GET_TRANSFORMATION_VERSION` | Get Transformation Version | Retrieve a single transformation revision by transformation ID and version ID. Use when you need to get details about a specific version of a RudderStack transformation. | | `RUDDERSTACK_TRANSFORMATION_LIST_ALL_LIBRARIES` | List All Libraries | Tool to retrieve all published libraries for a workspace. Use when you need to list available libraries for transformations. | | `RUDDERSTACK_TRANSFORMATION_LIST_LIBRARY_VERSIONS` | List Library Versions | Tool to get all library revisions for a library ID. Use when you need to retrieve all versions of a specific library in RudderStack Transformation. | | `RUDDERSTACK_TRANSFORMATION_LIST_ALL_TRANSFORMATIONS` | List All Transformations | Tool to retrieve all published transformations for a workspace. Use when you need to list available transformations or find a specific transformation by name. | | `RUDDERSTACK_TRANSFORMATION_LIST_TRANSFORMATION_VERSIONS` | List Transformation Versions | Tool to list all transformation versions (revisions) for a given transformation ID. Use when you need to retrieve the version history of a specific transformation. | | `RUDDERSTACK_TRANSFORMATION_UPDATE_TRANSFORMATION` | Update Transformation | Tool to update and optionally publish a RudderStack transformation. Use when you need to modify a transformation's name, description, or code. Updating creates a new revision and sets it as published if the publish flag is true. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The RudderStack Transformation MCP server provides comprehensive access to RudderStack Transformation operations through Composio.

With a standalone RudderStack Transformation MCP server, the agents and LLMs can only access a fixed set of RudderStack Transformation tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from RudderStack Transformation 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 RudderStack Transformation tools. ### Can I manage the permissions and scopes for RudderStack Transformation while using Tool Router? Yes, absolutely. You can configure which RudderStack Transformation 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 RudderStack Transformation data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) ยท [Composio docs](https://docs.composio.dev/llms.txt)
