This guide explains the easiest and most robust way to connect your Brex 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 Brex with - [OpenAI Agents SDK](https://composio.dev/toolkits/brex/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/brex/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/brex/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/brex/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/brex/framework/codex) - [OpenClaw](https://composio.dev/toolkits/brex/framework/openclaw) - [CLI](https://composio.dev/toolkits/brex/framework/cli) - [Google ADK](https://composio.dev/toolkits/brex/framework/google-adk) - [LangChain](https://composio.dev/toolkits/brex/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/brex/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/brex/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/brex/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/brex/framework/crew-ai) ## TL;DR ### What is Composio Connect? Composio Connect is a consumer offering that lets anyone plug 1,000+ applications directly into their agent harness โ€” 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 Brex to Hermes ### Integrating Brex 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 Brex MCP server, and what's possible with it? The Brex MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Brex account. It provides structured and secure access to your company's financial tools, so your agent can perform actions like managing cards, tracking expenses, creating budgets, and retrieving account details on your behalf. - Card creation and management: Instantly issue new cards, assign them to users or vendors, and control spending limits via your agent. - Automated expense tracking: Let your agent create and log expenses, helping you keep company finances organized and up to date. - Budget and department setup: Quickly create budgets for teams or projects and set up new departments without manual effort. - Account and statement retrieval: Fetch detailed account information and download statements whenever you need financial insights or records. - User and location management: Add new users or locations to your Brex account, making it easy to scale as your business grows. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `BREX_CREATE_BUDGET` | Create Budget | Create a new budget for departments or projects. | | `BREX_CREATE_CARD` | Create Card | Create a new card and assign it to a user. | | `BREX_CREATE_DEPARTMENT` | Create Department | Create a new department. | | `BREX_CREATE_EXPENSE` | Create Expense | Create a new expense. | | `BREX_CREATE_LOCATION` | Create Location | Create a new location. | | `BREX_CREATE_TITLE` | Create Job Title | Create a new job title. | | `BREX_CREATE_USER` | Create User | Create a new user in the brex account. | | `BREX_CREATE_VENDOR_CARD` | Create Vendor Card | Create a new vendor card. | | `BREX_GET_ACCOUNT_DETAILS` | Get Account Details | Get details about the current brex account. | | `BREX_GET_ACCOUNT_STATEMENTS` | Get Account Statements | Get account statements. | | `BREX_GET_BUDGET_DETAILS` | Get Budget Details | Get detailed information about a specific budget. | | `BREX_GET_BUDGET_TRANSACTIONS` | Get Budget Transactions | Get transactions for a specific budget. | | `BREX_GET_CARD_DETAILS` | Get Card Details | Get detailed information about a specific card. | | `BREX_GET_CARD_TRANSACTIONS` | Get Card Transactions | Get card transactions for a date range. | | `BREX_GET_COMPANY_CASH_ACCOUNTS` | Get Company Cash Accounts | Get company cash accounts. | | `BREX_GET_EXPENSE_DETAILS` | Get Expense Details | Get details of a specific expense. | | `BREX_GET_EXPENSES` | Get Expenses | Get expenses for a date range. | | `BREX_GET_SPEND_LIMITS` | Get Spend Limits | Get spend limits configuration. | | `BREX_GET_TRANSACTION_BY_ID` | Get Transaction by ID | Get details of a specific transaction by id. | | `BREX_GET_TRANSACTIONS` | Get Transactions | Get transactions for a date range. | | `BREX_GET_TRANSACTIONS_BY_AMOUNT_RANGE` | Get Transactions by Amount Range | Get transactions filtered by amount range. | | `BREX_GET_TRANSACTIONS_BY_DESCRIPTION` | Get Transactions by Description | Get transactions filtered by description text. | | `BREX_GET_USER_PROFILE` | Get User Profile | Get user profile information for current or specified user. | | `BREX_LIST_BUDGETS` | List Budgets | List all budgets and show available amounts across all cards. | | `BREX_LIST_CARDS` | List Cards | List all cards associated with the account. | | `BREX_LIST_DEPARTMENTS` | List Departments | List all departments in the organization. | | `BREX_LIST_LOCATIONS` | List Locations | List all locations in the organization. | | `BREX_LIST_TITLES` | List Job Titles | List all job titles in the organization. | | `BREX_LIST_USERS` | List Users | List all users in the brex account. | | `BREX_LIST_VENDORS` | List Vendors | List all vendors. | | `BREX_TRANSFER_CARD` | Transfer Card | Transfer a card to a different user. | | `BREX_UPDATE_BUDGET` | Update Budget | Update budget details. | | `BREX_UPDATE_CARD_LIMITS` | Update Card Limits | Update spending limits and controls for a card. | | `BREX_UPDATE_CARD_STATUS` | Update Card Status | Update the status of a card (activate/deactivate/terminate). | | `BREX_UPDATE_USER` | Update User | Update user details. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The Brex MCP server provides comprehensive access to Brex operations through Composio. Once connected, Hermes can perform all major Brex actions on your behalf using natural language commands. ## Complete Code None listed. ## Conclusion ### Way Forward With Brex 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 โ€” 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 Brex MCP server, the agents and LLMs can only access a fixed set of Brex tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Brex 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 Brex tools. ### Can I manage the permissions and scopes for Brex while using Tool Router? Yes, absolutely. You can configure which Brex 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 Brex 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)
