## Introduction

Codex is one of the most popular coding harnesses out there. And MCP makes the experience even better. With Fullenrich 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 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 Fullenrich to Codex

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

The Fullenrich MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Fullenrich account. It provides structured and secure access to powerful B2B contact enrichment features, so your agent can perform actions like preparing contact lists, starting bulk enrichment jobs, retrieving batch results, and monitoring credit usage on your behalf.
- Prepare and validate contact data lists: Guide your agent to create properly formatted lists of lead information for bulk enrichment, ensuring accuracy and readiness for processing.
- Launch bulk enrichment jobs: Let your agent start large-scale enrichment tasks for up to 100 contacts at a time, aggregating verified emails and phone numbers from multiple vendors.
- Retrieve bulk enrichment results: Automatically check on the status of ongoing jobs and fetch enriched contact data as soon as it's ready, streamlining your lead generation workflows.
- Monitor workspace credit balance: Enable your agent to check your current API credit usage so you always know how many enrichment requests you have remaining.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `FULLENRICH_CREATE_CONTACT_DATA_LIST` | Create Contact Data List | Tool to create a list of contact data entries. Use when preparing the 'datas' payload for bulk enrichment; validates each contact's composition and returns a JSON-ready list. |
| `FULLENRICH_GET_CURRENT_CREDIT_BALANCE` | Get current credit balance | Tool to retrieve current workspace credit balance. Use after authenticating your API key. |
| `FULLENRICH_FULLENRICH_GET_ENRICHMENT_RESULT` | Get Bulk Enrichment Result | Tool to retrieve results of a bulk enrichment by enrichment ID. Use after submitting a bulk enrichment job to check its status and get enriched data. |
| `FULLENRICH_GET_REVERSE_EMAIL_RESULT` | Get Reverse Email Result | Tool to retrieve results from a reverse email lookup operation using reverse email ID. Use after submitting a reverse email lookup to check its status and get contact data. |
| `FULLENRICH_REVERSE_EMAIL_LOOKUP` | Reverse Email Lookup | Tool to perform bulk reverse email lookup to retrieve full person and company profile from work or personal email addresses. Use when you have email addresses and need to enrich them with complete contact information. Results are processed asynchronously; use the returned enrichment_id to retrieve actual data. |
| `FULLENRICH_SEARCH_COMPANY` | Search Company | Tool to search for companies based on filters including name, domain, industry, type, headquarters location, headcount, and founded year. Multiple filters within the same field are combined with OR logic. Use when you need to find companies matching specific criteria. |

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

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

## Complete Code

None listed.

## Conclusion

### Conclusion
You've successfully integrated Fullenrich with Codex using Composio's MCP server. Now you can interact with Fullenrich 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 Fullenrich operations
- Managed authentication through Composio
- Access to 20,000+ tools across 1000+ apps for cross-app workflows
- CodeAct workbench for complex tool chaining
Next steps:
- Try asking Codex to perform various Fullenrich 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 Fullenrich MCP?

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

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

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