## Introduction

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

## Also integrate Fillout forms with

## 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 Fillout forms to Codex

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

The Fillout forms MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Fillout account. It provides structured and secure access to your forms and form management tools, so your agent can fetch form data, list all your forms, manage authorization, and help automate form workflows on your behalf.
- Comprehensive form listing: Instantly retrieve and display a list of all forms in your Fillout account, making it easy to review and manage your surveys and data collection tools.
- Seamless authorization management: Let your agent handle the OAuth authorization flow for securely connecting third-party applications to your Fillout account—no manual steps required.
- Token revocation and security: Instruct your agent to programmatically invalidate or revoke access tokens, ensuring that only trusted applications and users have access to your Fillout data.
- Automated workflow integration: Use your agent to connect Fillout forms with other apps or workflows, streamlining data collection and processing without manual intervention.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `FILLOUT_FORMS_AUTHORIZE_O_AUTH` | Authorize OAuth | Tool to initiate the oauth authorization process for third-party applications. use when you need to generate the url to redirect your users to the fillout consent page. |
| `FILLOUT_FORMS_GET_FORMS` | Get forms | Tool to retrieve a list of all forms in your account. use when you need to list your forms after authenticating with fillout. |
| `FILLOUT_FORMS_INVALIDATE_ACCESS_TOKEN` | Invalidate Access Token | Tool to revoke an existing oauth access token. use when the user logs out or you need to programmatically invalidate a token after deauthorization. example: "invalidate token abcdefg123456". this endpoint does not return a json body. successful calls return http 200 or 204. |

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Fillout forms MCP?

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

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

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