And MCP makes the experience even better. With Respond io MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer. ## Also integrate Respond io with - [OpenAI Agents SDK](https://composio.dev/toolkits/respond_io/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/respond_io/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/respond_io/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/respond_io/framework/claude-cowork) - [OpenClaw](https://composio.dev/toolkits/respond_io/framework/openclaw) - [Hermes](https://composio.dev/toolkits/respond_io/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/respond_io/framework/cli) - [Google ADK](https://composio.dev/toolkits/respond_io/framework/google-adk) - [LangChain](https://composio.dev/toolkits/respond_io/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/respond_io/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/respond_io/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/respond_io/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/respond_io/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 Respond io to Codex ### How to install Respond io 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 Respond io MCP server, and what's possible with it? The Respond io MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Respond io account. It provides structured and secure access to your customer conversation management platform, so your agent can perform actions like managing contacts, adding internal comments, creating and updating tags, and retrieving messages on your behalf. - Create and manage contacts: Easily have your agent add new customer contacts to your workspace, ensuring your CRM is always up to date. - Add internal comments to conversations: Let your agent insert internal notes into customer conversations, keeping your team informed and collaborating seamlessly. - Retrieve and organize channels: Direct your agent to list all messaging channels connected to your workspace, making it simple to audit or assign channels for support. - Tag and categorize conversations: Enable your agent to create new tags or update existing ones, helping you organize contacts and conversations for efficient follow-up. - Fetch specific messages: Ask your agent to pull up particular messages for review or context, streamlining support and follow-up actions. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `RESPOND_IO_CREATE_COMMENT` | Add internal comment to conversation | Tool to add a comment (internal note) to a contact's conversation. Use after verifying the contact identifier. | | `RESPOND_IO_CREATE_CONTACT` | Create Contact | Creates a new contact in the respond.io workspace with the specified details. The contact is identified by email, phone number, or contact ID. Supports adding profile information, language preferences, and custom fields that have been pre-configured in the workspace. | | `RESPOND_IO_CREATE_SPACE_TAG` | Create Space Tag | Creates a new tag in the Respond.io workspace for organizing and categorizing contacts and conversations. Tags help with segmentation, filtering, and workflow automation. Each tag must have a unique name within the workspace. | | `RESPOND_IO_GET_MESSAGE` | Get Message | Tool to retrieve a specific message. Use when you need the details of a message sent to or received from a contact. | | `RESPOND_IO_LIST_CHANNELS` | List channels | Tool to retrieve a list of channels connected to the workspace. Use when you need to enumerate all messaging channels with pagination support. | | `RESPOND_IO_LIST_USERS` | List users | Tool to retrieve a list of users in the workspace. Use when you need to fetch all workspace users for auditing or assignment. | | `RESPOND_IO_UPDATE_SPACE_TAG` | Update Space Tag | Updates an existing workspace tag by its current name. You can modify the tag's name, description, or emoji. Note: Color codes are not currently supported by the API and will be rejected if provided. At least one field besides currentName must be provided to update. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The Respond io MCP server provides comprehensive access to Respond io operations through Composio. Once connected, you can perform all major Respond io actions directly from Codex using natural language commands. ## Complete Code None listed. ## Conclusion ### Conclusion You've successfully integrated Respond io with Codex using Composio's MCP server.

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