It takes action across your apps and files, stays with a project for hours, and turns a goal into finished materials like sheets, slides, and docs - not just answers. In this guide, I will explain the easiest and most secure way to connect your Braintrust account to ChatGPT Work via Composio Connect, so it can compare failed evaluations across recent experiments, create dataset from production failure logs, summarize latency spikes in braintrust traces through natural language commands without ever putting your account credentials at risk. ## Also integrate Braintrust with - [Claude Cowork](https://composio.dev/toolkits/braintrust/framework/claude-cowork) - [Hermes](https://composio.dev/toolkits/braintrust/framework/hermes-agent) ## TL;DR ### Why use Composio over default connectors? - Apps with read and write access. Default connectors mostly can read your data. Composio's Braintrust integration lets ChatGPT Work take actions like creating drafts, sending updates, labeling records, and more. - 1,000+ SaaS toolkits out of the box. Composio gives you instant access to a vast catalog of pre-built connectors, from Gmail and Slack to Notion, Linear, and Salesforce. - One MCP server for every app. Connect any of your applications on demand through a single endpoint, rather than juggling a separate server for each app. - Smart, context-aware tool loading. Unlike traditional MCP servers that dump every available tool into the LLM context window, Composio searches for and loads only the tools relevant to the task at hand. - Cross-app automation. Chain actions across multiple apps in a single run - fetch a thread, summarize it in Notion, and post highlights to Slack without leaving the conversation. ## Connect Braintrust to ChatGPT Work ### Prerequisites - A ChatGPT account with access to ChatGPT Work (rolling out across Pro, Enterprise, Edu, Plus, and Business plans). We will use the [ChatGPT desktop app](https://openai.com/chatgpt/download/), which is available on every plan. - Access to the Braintrust workspace you want to connect. - [Composio MCP](https://dashboard.composio.dev/login?utm_source=toolkits&utm_medium=framework_template&utm_campaign=chatgpt&utm_content=composio_connect&next=%2F~%2Forg%2Fconnect%2Fclients%2Fchatgpt). Note: Composio connects through OAuth. You will be asked to sign in and approve specific permissions. Review the permission screen carefully if you are using a work account. ### Step-by-step: Connect Braintrust to ChatGPT Work ### 1. Open the MCP settings In ChatGPT Work, go to Settings and open the Plugins section. Inside the Plugins page, click the MCP tab. ### 2. Add the server Click Add server. In the Name field enter Composio, for Type select Streamable HTTP, and in the URL field paste the Composio MCP server URL: ```bash https://connect.composio.dev/mcp ``` ## What is the Braintrust MCP server, and what's possible with it? The Braintrust MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Braintrust account. It provides structured and secure access so your agent can perform Braintrust operations on your behalf. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `BRAINTRUST_CREATE_DATASET` | Create Dataset | Create a named dataset under a Braintrust project, or return the existing dataset unchanged when its name already exists in that project. | | `BRAINTRUST_CREATE_EXPERIMENT` | Create Experiment | Create an experiment under a Braintrust project. When its name already exists, Braintrust returns the existing experiment unchanged unless ensure_new is true, which creates an experiment with a unique name. | | `BRAINTRUST_CREATE_PROJECT` | Create Project | Create a Braintrust project, or return the existing project unchanged when its name already exists. | | `BRAINTRUST_CREATE_PROMPT` | Create Prompt | Upsert a versioned prompt configuration under a Braintrust project without invoking it.

New or omitted IDs insert events; an existing supplied ID replaces that event's current values. | | `BRAINTRUST_LIST_RESOURCES` | List Braintrust Resources | List and filter one page of projects, experiments, datasets, prompts, or functions visible to the connected Braintrust API key. | | `BRAINTRUST_QUERY_DATA` | Query Braintrust Data | Run one bounded synchronous read-only BTQL query over Braintrust project logs, an experiment, or a dataset. The first-page query must end with a positive LIMIT; continue later pages by passing the returned next_cursor unchanged. | | `BRAINTRUST_SUMMARIZE_RESOURCE` | Summarize Experiment or Dataset | Return metadata and optional aggregate summaries for one Braintrust experiment or dataset. | | `BRAINTRUST_UPDATE_DATASET` | Update Dataset | Update the name, description, tags, or metadata of a Braintrust dataset. At least one non-null mutable field is required. | | `BRAINTRUST_UPDATE_EXPERIMENT` | Update Experiment | Update selected metadata and linkage fields on a Braintrust experiment. At least one non-null mutable field is required. | | `BRAINTRUST_UPDATE_PROJECT` | Update Project | Update selected fields of a Braintrust project. At least one non-null mutable field is required: name, description, or settings. | | `BRAINTRUST_UPDATE_PROMPT` | Update Prompt | Update a Braintrust prompt's metadata or configuration without invoking it. At least one non-null mutable field is required. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK Once connected, ChatGPT Work can access the Braintrust MCP server via Composio to run actions that you authorize, directly in your workspace. ## Complete Code None listed. ## How to build Braintrust MCP Agent with another framework - [Claude Cowork](https://composio.dev/toolkits/braintrust/framework/claude-cowork) - [Hermes](https://composio.dev/toolkits/braintrust/framework/hermes-agent) ## Related Toolkits - [Composio](https://composio.dev/toolkits/composio) - Composio is an integration platform that connects AI agents with hundreds of business tools.

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