And MCP makes the experience even better. With Instantly MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer. ## Also integrate Instantly with - [OpenAI Agents SDK](https://composio.dev/toolkits/instantly/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/instantly/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/instantly/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/instantly/framework/claude-cowork) - [OpenClaw](https://composio.dev/toolkits/instantly/framework/openclaw) - [Hermes](https://composio.dev/toolkits/instantly/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/instantly/framework/cli) - [Google ADK](https://composio.dev/toolkits/instantly/framework/google-adk) - [LangChain](https://composio.dev/toolkits/instantly/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/instantly/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/instantly/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/instantly/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/instantly/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 Instantly to Codex ### How to install Instantly 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 Instantly MCP server, and what's possible with it? The Instantly MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Instantly account. It provides structured and secure access to your campaigns, leads, and outreach tools, so your agent can perform actions like launching new campaigns, managing leads, tracking inbox statistics, and handling API credentials on your behalf. - Automated campaign creation and management: Ask your agent to launch new cold email campaigns or update existing ones, streamlining your outreach workflow without manual setup. - Lead and lead list management: Let your agent add new leads, organize them into lists, or enrich them with AI-driven insights to maximize your campaign effectiveness. - Email verification and deliverability tracking: Direct your agent to check the verification status of email addresses or run inbox placement tests to monitor and improve deliverability across providers. - Inbox activity monitoring: Fetch unread email counts or campaign engagement metrics, helping you stay on top of your outreach performance in real time. - API key and webhook automation: Have your agent create or delete API keys for secure integrations, or set up webhooks to receive instant notifications about important Instantly events. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `INSTANTLY_CHECK_EMAIL_VERIFICATION_STATUS` | Check Email Verification Status | Tool to check status of an email verification job.

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