And MCP makes the experience even better. With Refiner MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer. ## Also integrate Refiner with - [OpenAI Agents SDK](https://composio.dev/toolkits/refiner/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/refiner/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/refiner/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/refiner/framework/claude-cowork) - [OpenClaw](https://composio.dev/toolkits/refiner/framework/openclaw) - [Hermes](https://composio.dev/toolkits/refiner/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/refiner/framework/cli) - [Google ADK](https://composio.dev/toolkits/refiner/framework/google-adk) - [LangChain](https://composio.dev/toolkits/refiner/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/refiner/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/refiner/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/refiner/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/refiner/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 Refiner to Codex ### How to install Refiner 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 Refiner MCP server, and what's possible with it? The Refiner MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Refiner account. It provides structured and secure access to your customer feedback and survey data, so your agent can perform actions like fetching contacts, analyzing survey responses, managing user segments, updating user data, and generating reports on your behalf. - Contact management and updates: Effortlessly retrieve, update, or delete contact records, allowing your agent to keep user data clean and up-to-date. - Survey and form discovery: Instantly list all surveys or forms in your Refiner account, filter by state, and access their configurations for deeper analysis or reporting. - Survey response retrieval and analytics: Pull in all survey responses, filter results, and generate detailed analytics or reporting to uncover actionable insights from your customer feedback. - User segmentation and targeting: Fetch and browse user segments, enabling your agent to target specific groups for outreach or further analysis based on collected data. - Event tracking and behavioral logging: Automatically record user events, associate them with contacts, and enrich feedback data for advanced behavioral analytics. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `REFINER_DELETE_CONTACT` | Delete Contact | Tool to delete a specific contact by its identifier. Provide either the user ID or email address to identify and delete the contact. | | `REFINER_GET_ACCOUNT_INFO` | Get Account Info | Retrieves Refiner account information including subscription plan, usage limits, and environment statistics. This action provides: - Current subscription plan and usage limits (MTU, MTE, MPV, MSR) - Usage counters for monthly tracked users, events, page views, and survey responses - Per-environment breakdown of usage statistics - Last updated timestamps for all usage metrics Use this when you need to check account status, monitor usage against limits, or audit environment statistics. | | `REFINER_GET_CONTACT` | Get Contact | Retrieve detailed information about a specific contact using their ID, email, or UUID. Returns all stored attributes, segments, and account information. | | `REFINER_GET_CONTACTS` | Get Contacts | Tool to retrieve a list of contacts from your Refiner account. Use when you need to filter or paginate through contacts. | | `REFINER_GET_FORMS` | Get Forms | Tool to retrieve a list of forms (surveys) from your Refiner account with optional filtering and pagination. Use when you need to list surveys by state, page, or include extra info/config. | | `REFINER_GET_REPORTING` | Get Reporting | Tool to retrieve aggregated reporting data for surveys including metrics and analytics. Use when you need survey analytics over a time range filtered by type, question identifiers, tags, forms, or segments. | | `REFINER_GET_RESPONSES` | Get Survey Responses | Tool to retrieve all survey responses from your Refiner account with optional filtering and pagination. Use after confirming survey creation to pull response data. | | `REFINER_GET_SEGMENTS` | Get Segments | Tool to retrieve a list of user segments from your Refiner account. Use when you need to view or paginate segments. | | `REFINER_TRACK_EVENT` | Track Event | Tool to record a user event by name for a user identified via user ID or email. Use after confirming the identifier and event name. | | `REFINER_UPDATE_CONTACT` | Update Contact | Tool to create or update a contact's attributes or account. Identifies a contact by `id` or `email` and updates their traits or account grouping. If the contact doesn't exist, it will be created automatically. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The Refiner MCP server provides comprehensive access to Refiner operations through Composio.

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