And MCP makes the experience even better. With Tomba MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer. ## Also integrate Tomba with - [OpenAI Agents SDK](https://composio.dev/toolkits/tomba/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/tomba/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/tomba/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/tomba/framework/claude-cowork) - [OpenClaw](https://composio.dev/toolkits/tomba/framework/openclaw) - [Hermes](https://composio.dev/toolkits/tomba/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/tomba/framework/cli) - [Google ADK](https://composio.dev/toolkits/tomba/framework/google-adk) - [LangChain](https://composio.dev/toolkits/tomba/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/tomba/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/tomba/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/tomba/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/tomba/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 Tomba to Codex ### How to install Tomba 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 Tomba MCP server, and what's possible with it? The Tomba MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Tomba account. It provides structured and secure access to your B2B email finding, lead management, and account configuration tools, so your agent can perform actions like discovering leads, managing lists, validating domains, and monitoring account usage on your behalf. - Lead discovery and enrichment: Ask your agent to list available lead attributes or add new leads directly into your Tomba account for streamlined outreach. - Lead list management: Effortlessly retrieve, update, or delete lead lists, helping you stay organized and keep your data current. - Domain validation and status checks: Have your agent check if a domain is webmail or disposable to ensure better deliverability and lead quality. - API key and account management: Direct your agent to list, create, or revoke API keys, and review usage statistics to keep your Tomba integration secure and efficient. - Usage monitoring and reporting: Let your agent fetch up-to-date API usage statistics, keeping you informed about your plan limits and consumption. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `TOMBA_ATTRIBUTES_LIST` | List Lead Attributes | Retrieves all custom lead attributes defined in your Tomba account. Use this action to discover the available attributes that can be used when creating or updating leads. Returns attribute metadata including name, identifier, type, and timestamps.

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