## Introduction

This guide walks you through connecting Esignatures io to the OpenAI Agents SDK using the Composio tool router. By the end, you'll have a working Esignatures io agent that can send a contract to a new client for signature, list all available contract templates, withdraw a contract that hasn't been signed through natural language commands.
This guide will help you understand how to give your OpenAI Agents SDK agent real control over a Esignatures io account through Composio's Esignatures io MCP server.
Before we dive in, let's take a quick look at the key ideas and tools involved.

## TL;DR

Here's what you'll learn:
- Get and set up your OpenAI and Composio API keys
- Install the necessary dependencies
- Initialize Composio and create a Tool Router session for Esignatures io
- Configure an AI agent that can use Esignatures io as a tool
- Run a live chat session where you can ask the agent to perform Esignatures io operations

## What is OpenAI Agents SDK?

The OpenAI Agents SDK is a lightweight framework for building AI agents that can use tools and maintain conversation state. It provides a simple interface for creating agents with hosted MCP tool support.
Key features include:
- Hosted MCP Tools: Connect to external services through hosted MCP endpoints
- SQLite Sessions: Persist conversation history across interactions
- Simple API: Clean interface with Agent, Runner, and tool configuration
- Streaming Support: Real-time response streaming for interactive applications

## What is the Esignatures io MCP server, and what's possible with it?

The Esignatures io MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Esignatures io account. It provides structured and secure access to your contract management tools, so your agent can create contracts, manage templates, handle signer profiles, and control contract workflows seamlessly on your behalf.
- Automated contract creation and sending: Instantly generate and send new contracts for signature using pre-built templates and custom signer details.
- Template management and organization: Allow your agent to create, retrieve, list, and delete contract templates for easy document standardization and reuse.
- Signer profile creation: Effortlessly add new signers to your account, making it simple to initiate or update signature requests as needed.
- Contract withdrawal and workflow control: Instantly withdraw contracts that should no longer be signed, preventing further action on outdated or incorrect documents.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `ESIGNATURES_IO_ADD_TEMPLATE_COLLABORATOR` | Add Template Collaborator | Tool to grant editing access to a template with optional email invitation. Use when you need to add a collaborator who can edit the template. |
| `ESIGNATURES_IO_COPY_TEMPLATE` | Copy Template | Tool to duplicate an existing template with optional customization. Use when you need to create a new template based on an existing one. |
| `ESIGNATURES_IO_CREATE_CONTRACT` | Create Contract | Tool to create a new contract using a specified template and signer details. Use after selecting a template when you need to send a contract for signature. |
| `ESIGNATURES_IO_CREATE_SIGNER` | Create Signer | Add a signer to an existing contract/signature request. This action queues the addition of a new signer to a contract that has already been created. The signer will be added asynchronously and will receive their signing invitation via email. Use this when you need to add additional signers to a contract after it has been created, or when you want to add signers incrementally rather than all at once during contract creation. Note: The API returns a queued status, indicating the operation has been accepted for processing. Adding a new signer does not automatically send an email notification unless the contract settings are configured to do so. |
| `ESIGNATURES_IO_CREATE_TEMPLATE` | Create Template | Tool to create a new template. Use when you want to register a reusable contract template after defining document elements. |
| `ESIGNATURES_IO_DELETE_SIGNER` | Delete Signer | Tool to remove a signer from a contract. Use when you need to revoke a signer's access to sign a contract. |
| `ESIGNATURES_IO_DELETE_TEMPLATE` | Delete Template | Tool to delete a specific template by its ID. Use when you need to remove an unused or outdated template after confirming its ID. |
| `ESIGNATURES_IO_GENERATE_CONTRACT_PDF_PREVIEW` | Generate Contract PDF Preview | Tool to generate a PDF preview of a contract and receive a webhook notification with a download URL. Use when you need to preview the contract document before or after signing. |
| `ESIGNATURES_IO_GET_CONTRACT` | Get Contract | Tool to retrieve details of a specific contract by its ID. Returns contract status, signer information, and values entered by signers. Use when you need to check contract status or download signed PDF. |
| `ESIGNATURES_IO_GET_TEMPLATE` | Get Template | Tool to retrieve details of a specific template by its ID. Use when you need to fetch a template’s metadata after selecting its ID. |
| `ESIGNATURES_IO_LIST_TEMPLATE_COLLABORATORS` | List Template Collaborators | Tool to retrieve all collaborators with editing access to a template. Returns collaborator IDs, names, emails, and editor URLs. |
| `ESIGNATURES_IO_LIST_TEMPLATES` | List Templates | Tool to retrieve a list of all templates. Use when you need to browse available templates before selecting one. |
| `ESIGNATURES_IO_REMOVE_TEMPLATE_COLLABORATOR` | Remove Template Collaborator | Tool to revoke a collaborator's template editing permissions. Use when you need to remove access for a specific collaborator from a template. |
| `ESIGNATURES_IO_SEND_CONTRACT_TO_SIGNER` | Send Contract to Signer | Tool to send or resend a contract signature request to a specific signer via their configured communication channel. Use when you need to deliver a contract to a signer for their signature. |
| `ESIGNATURES_IO_UPDATE_SIGNER` | Update Signer | Tool to update contact details of an existing signer on a contract. Use when you need to change a signer's name, email, or mobile number. Note: The contract is not automatically emailed when the signer's information is updated. |
| `ESIGNATURES_IO_UPDATE_TEMPLATE` | Update Template | Tool to update an existing template's content, title, or labels. Use when you need to modify a template's configuration without creating a new one. |
| `ESIGNATURES_IO_WITHDRAW_CONTRACT` | Withdraw Contract | Tool to withdraw a contract by its ID. Use when you need to prevent further signing of a contract that hasn't been fully signed. |

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

The Esignatures io MCP server is an implementation of the Model Context Protocol that connects your AI agent to Esignatures io. It provides structured and secure access so your agent can perform Esignatures io operations on your behalf through a secure, permission-based interface.
With Composio's managed implementation, you don't have to create your own developer app. For production, if you're building an end product, we recommend using your own credentials. The managed server helps you prototype fast and go from 0-1 faster.

## Step-by-step Guide

### 1. Prerequisites

Before starting, make sure you have:
- Composio API Key and OpenAI API Key
- Primary know-how of OpenAI Agents SDK
- A live Esignatures io project
- Some knowledge of Python or Typescript

### 1. Getting API Keys for OpenAI and Composio

OpenAI API Key
- Go to the [OpenAI dashboard](https://platform.openai.com/settings/organization/api-keys) and create an API key. You'll need credits to use the models, or you can connect to another model provider.
- Keep the API key safe.
Composio API Key
- Log in to the [Composio dashboard](https://dashboard.composio.dev?utm_source=toolkits&utm_medium=framework_docs).
- Go to Settings and copy your API key.

### 2. Install dependencies

Install the Composio SDK and the OpenAI Agents SDK.
```python
pip install composio_openai_agents openai-agents python-dotenv
```

```typescript
npm install @composio/openai-agents @openai/agents dotenv
```

### 3. Set up environment variables

Create a .env file and add your OpenAI and Composio API keys.
```bash
OPENAI_API_KEY=sk-...your-api-key
COMPOSIO_API_KEY=your-api-key
USER_ID=composio_user@gmail.com
```

### 4. Import dependencies

What's happening:
- You're importing all necessary libraries.
- The Composio and OpenAIAgentsProvider classes are imported to connect your OpenAI agent to Composio tools like Esignatures io.
```python
import asyncio
import os
from dotenv import load_dotenv

from composio import Composio
from composio_openai_agents import OpenAIAgentsProvider
from agents import Agent, Runner, HostedMCPTool, SQLiteSession
```

```typescript
import 'dotenv/config';
import { Composio } from '@composio/core';
import { OpenAIAgentsProvider } from '@composio/openai-agents';
import { Agent, hostedMcpTool, run, OpenAIConversationsSession } from '@openai/agents';
import * as readline from 'readline';
```

### 5. Set up the Composio instance

No description provided.
```python
load_dotenv()

api_key = os.getenv("COMPOSIO_API_KEY")
user_id = os.getenv("USER_ID")

if not api_key:
    raise RuntimeError("COMPOSIO_API_KEY is not set. Create a .env file with COMPOSIO_API_KEY=your_key")

# Initialize Composio
composio = Composio(api_key=api_key, provider=OpenAIAgentsProvider())
```

```typescript
dotenv.config();

const composioApiKey = process.env.COMPOSIO_API_KEY;
const userId = process.env.USER_ID;

if (!composioApiKey) {
  throw new Error('COMPOSIO_API_KEY is not set. Create a .env file with COMPOSIO_API_KEY=your_key');
}
if (!userId) {
  throw new Error('USER_ID is not set');
}

// Initialize Composio
const composio = new Composio({
  apiKey: composioApiKey,
  provider: new OpenAIAgentsProvider(),
});
```

### 6. Create a Tool Router session

What is happening:
- You give the Tool Router the user id and the toolkits you want available. Here, it is only esignatures_io.
- The router checks the user's Esignatures io connection and prepares the MCP endpoint.
- The returned session.mcp.url is the MCP URL that your agent will use to access Esignatures io.
- This approach keeps things lightweight and lets the agent request Esignatures io tools only when needed during the conversation.
```python
# Create a Esignatures io Tool Router session
session = composio.create(
    user_id=user_id,
    toolkits=["esignatures_io"]
)

mcp_url = session.mcp.url
```

```typescript
// Create Tool Router session for Esignatures io
const session = await composio.create(userId as string, {
  toolkits: ['esignatures_io'],
});
const mcpUrl = session.mcp.url;
```

### 7. Configure the agent

No description provided.
```python
# Configure agent with MCP tool
agent = Agent(
    name="Assistant",
    model="gpt-5",
    instructions=(
        "You are a helpful assistant that can access Esignatures io. "
        "Help users perform Esignatures io operations through natural language."
    ),
    tools=[
        HostedMCPTool(
            tool_config={
                "type": "mcp",
                "server_label": "tool_router",
                "server_url": mcp_url,
                "headers": {"x-api-key": api_key},
                "require_approval": "never",
            }
        )
    ],
)
```

```typescript
// Configure agent with MCP tool
const agent = new Agent({
  name: 'Assistant',
  model: 'gpt-5',
  instructions:
    'You are a helpful assistant that can access Esignatures io. Help users perform Esignatures io operations through natural language.',
  tools: [
    hostedMcpTool({
      serverLabel: 'tool_router',
      serverUrl: mcpUrl,
      headers: { 'x-api-key': composioApiKey },
      requireApproval: 'never',
    }),
  ],
});
```

## Conclusion

This was a starter code for integrating Esignatures io MCP with OpenAI Agents SDK to build a functional AI agent that can interact with Esignatures io.
Key features:
- Hosted MCP tool integration through Composio's Tool Router
- SQLite session persistence for conversation history
- Simple async chat loop for interactive testing
You can extend this by adding more toolkits, implementing custom business logic, or building a web interface around the agent.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Esignatures io MCP?

With a standalone Esignatures io MCP server, the agents and LLMs can only access a fixed set of Esignatures io tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Esignatures io and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with OpenAI Agents SDK?

Yes, you can. OpenAI Agents SDK 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 Esignatures io tools.

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

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