## Introduction

Codex is one of the most popular coding harnesses out there. And MCP makes the experience even better. With Leverly MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer.

## 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 Leverly to Codex

### How to install Leverly 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 Leverly MCP server, and what's possible with it?

The Leverly MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Leverly account. It provides structured and secure access to your Leverly workflows, so your agent can perform actions like listing reattempt histories, stopping ongoing reattempts, and streamlining automation management on your behalf.
- View reattempt history: Quickly ask your agent to retrieve a complete list of all ingestion reattempts for easy review and troubleshooting.
- Stop ongoing reattempts: Direct your agent to halt any ongoing reattempts for specific leads by providing the relevant reattempt ID.
- Monitor workflow automation: Let your agent inspect and keep tabs on the status of automated processes, ensuring nothing falls through the cracks.
- Accelerate process interventions: Empower your agent to step in and manage exceptions or stuck workflows by stopping unnecessary retries as needed.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `LEVERLY_LIST_REATTEMPTS` | List Reattempts | Tool to list all reattempts in leverly. use when you need to inspect the history of ingestion reattempts before taking further action. |
| `LEVERLY_STOP_REATTEMPTS` | Stop Leverly Reattempts | Tool to stop ongoing reattempts for a lead in leverly. use when you need to halt retries for a given reattempt id. |

## Supported Triggers

## Creating MCP Server - Stand-alone vs Composio SDK

The Leverly MCP server provides comprehensive access to Leverly operations through Composio. Once connected, you can perform all major Leverly actions directly from Codex using natural language commands.

## Complete Code

None listed.

## Conclusion

### Conclusion
You've successfully integrated Leverly with Codex using Composio's MCP server. Now you can interact with Leverly directly from your terminal, VS Code, or the Codex App using natural language commands.
Key benefits of this setup:
- Seamless integration across CLI, VS Code, and standalone app
- Natural language commands for Leverly operations
- Managed authentication through Composio
- Access to 20,000+ tools across 870+ apps for cross-app workflows
- CodeAct workbench for complex tool chaining
Next steps:
- Try asking Codex to perform various Leverly operations
- Explore cross-app workflows by connecting more toolkits
- Build automation scripts that leverage Codex's AI capabilities

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Leverly MCP?

With a standalone Leverly MCP server, the agents and LLMs can only access a fixed set of Leverly tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Leverly 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 Leverly tools.

### Can I manage the permissions and scopes for Leverly while using Tool Router?

Yes, absolutely. You can configure which Leverly 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 Leverly data and credentials are handled as safely as possible.
