And MCP makes the experience even better. With Finmei MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer. ## Also integrate Finmei with - [OpenAI Agents SDK](https://composio.dev/toolkits/finmei/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/finmei/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/finmei/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/finmei/framework/claude-cowork) - [OpenClaw](https://composio.dev/toolkits/finmei/framework/openclaw) - [Hermes](https://composio.dev/toolkits/finmei/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/finmei/framework/cli) - [Google ADK](https://composio.dev/toolkits/finmei/framework/google-adk) - [LangChain](https://composio.dev/toolkits/finmei/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/finmei/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/finmei/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/finmei/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/finmei/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 870+ other Apps for cross-app workflows. It loads the tools you need, so GPTs aren't overwhelmed by tools you don't need. ## Connect Finmei to Codex ### How to install Finmei 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 Finmei MCP server, and what's possible with it? The Finmei MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Finmei account. It provides structured and secure access to your invoicing and expense data, so your agent can perform actions like creating invoices, managing customers, tracking payments, and handling products on your behalf. - Smart invoice creation and management: Ask your agent to generate new invoices, list all existing invoices, or delete outdated ones—helping you stay on top of billing effortlessly. - Customer record management: Let your agent list all your customers, search for specific records, or delete customers no longer in your system, streamlining client data administration. - Payment tracking and retrieval: Retrieve payment details, verify payment statuses, or remove obsolete payments to keep your financial records accurate and up to date. - Product catalog maintenance: Easily fetch detailed product information or remove products from your catalog as your offerings evolve, all via agent commands. - Multi-currency support: Ask your agent to list all available currencies before creating invoices, ensuring transactions are processed in the correct denomination for your business needs. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `FINMEI_CREATE_INVOICE` | Create Invoice | Tool to create a new invoice.

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