This guide explains the easiest and most robust way to connect your Braintrust account to Hermes. You can do this through either Composio Connect CLI or Composio Connect MCP. For personal use we recommend the CLI, but you won't go wrong with MCP either. ## Also integrate Braintrust with - [ChatGPT Work](https://composio.dev/toolkits/braintrust/framework/chatgpt) - [Claude Cowork](https://composio.dev/toolkits/braintrust/framework/claude-cowork) ## TL;DR ### What is Composio Connect? Composio Connect is a consumer offering that lets anyone plug 1,000+ applications directly into their agent harness — including Hermes. It can: - Search and load tools from relevant toolkits on-demand, reducing context usage. - Chain multiple tools to accomplish complex workflows via a remote workbench, without excessive back-and-forth with the LLM. - Manage app authentication end-to-end with zero manual overhead. ## Connect Braintrust to Hermes ### Integrating Braintrust with Hermes ### Using Composio Connect CLI 1. Install the Composio CLI Run the install script directly, or paste https://composio.dev/hermes into your Hermes chat box to have it installed for you. ```bash curl -fsSL https://composio.dev/install | bash ``` ## 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. The same project and slug reuse the prompt ID but create a new version that replaces the stored prompt configuration with the submitted configuration. MCP attachments and tool-function bindings are unsupported. | | `BRAINTRUST_DELETE_PROJECT` | Delete Project | Soft-delete a Braintrust project and return its deletion state. | | `BRAINTRUST_DELETE_RESOURCE` | Delete Experiment, Dataset, or Prompt | Delete one Braintrust experiment, dataset, or prompt by UUID for explicit lifecycle cleanup. | | `BRAINTRUST_FETCH_EVENTS` | Fetch Events | Fetch one newest-to-oldest page of project log, experiment, or dataset events. | | `BRAINTRUST_GET_RESOURCE` | Get Braintrust Resource | Get one project, experiment, dataset, prompt, or function by UUID. | | `BRAINTRUST_INSERT_DATASET_EVENTS` | Insert Dataset Events | Upsert a batch of examples into an existing Braintrust dataset. New or omitted IDs insert events; an existing supplied ID replaces that event's current values. | | `BRAINTRUST_INSERT_EXPERIMENT_EVENTS` | Insert Experiment Events | Upsert a batch of result events into an existing Braintrust experiment. 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 The Braintrust MCP server provides comprehensive access to Braintrust operations through Composio. Once connected, Hermes can perform all major Braintrust actions on your behalf using natural language commands. ## Complete Code None listed. ## Conclusion ### Way Forward With Braintrust connected, Hermes can now act on your behalf whenever it detects a relevant task or you ask it to. From here, you can extend Hermes further: - Connect more apps: Calendar, Slack, Notion, Linear, and hundreds of others are available through the same Composio Connect setup. Each new integration compounds what Hermes can do for you. - Build workflows across tools: Once multiple apps are connected, Hermes can chain actions together — turn an email into a calendar invite, a Slack message into a Linear ticket, or a meeting note into a follow-up draft. - Let it learn your patterns: The more you use Hermes, the better it gets at anticipating how you'd handle recurring tasks. Give it feedback on drafts and decisions, and it will adapt.

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 Hermes? Yes, you can. Hermes 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)
