## Introduction

This guide walks you through connecting Eversign to the Claude Agent SDK using the Composio tool router. By the end, you'll have a working Eversign agent that can list all documents awaiting your signature, create a reusable nda template for hr, get the audit log for contract abc123 through natural language commands.
This guide will help you understand how to give your Claude Agent SDK agent real control over a Eversign account through Composio's Eversign 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 Claude/Anthropic and Composio API keys
- Install the necessary dependencies
- Initialize Composio and create a Tool Router session for Eversign
- Configure an AI agent that can use Eversign as a tool
- Run a live chat session where you can ask the agent to perform Eversign operations

## What is Claude Agent SDK?

The Claude Agent SDK is Anthropic's official framework for building AI agents powered by Claude. It provides a streamlined interface for creating agents with MCP tool support and conversation management.
Key features include:
- Native MCP Support: Built-in support for Model Context Protocol servers
- Permission Modes: Control tool execution permissions
- Streaming Responses: Real-time response streaming for interactive applications
- Context Manager: Clean async context management for sessions

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

The Eversign MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Eversign (Xodo Sign) account. It provides structured and secure access to your digital signature workflows, so your agent can create documents for signing, manage templates, reassign signers, and track document status—all automatically on your behalf.
- Automated document creation and sending: Let your agent generate new documents, set up signers, and send out signature requests in just a few steps.
- Template management and reuse: Effortlessly create, list, and manage reusable document templates to streamline repetitive signing tasks.
- Audit log and compliance tracking: Retrieve detailed audit logs for any document to review its full event history and maintain compliance records.
- Bulk job and business management: List all businesses tied to your account or view and paginate through bulk signature jobs with ease.
- Signer reassignment and workflow updates: Reassign signers on documents if someone leaves or needs to be swapped, keeping your signature flows moving smoothly.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `EVERSIGN_AUDIT_LOG` | Get Document Audit Log | Retrieves the complete audit trail for a document, showing all events from creation through completion. Use this after obtaining a document_hash from list_documents or create_document to track document lifecycle events, signer actions, and status changes. |
| `EVERSIGN_CREATE_DOCUMENT` | Create Document | Creates a new Eversign document for electronic signature collection from one or more signers. You can create documents either: 1. From a template (use EVERSIGN_LIST_TEMPLATES to find available templates, then specify template_id) 2. From uploaded files (provide file URLs, base64 content, or file IDs in the files array) Documents can be sent immediately to signers or saved as drafts. Use sandbox mode for testing. Returns the document_hash which can be used to track and manage the document. |
| `EVERSIGN_CREATE_TEMPLATE` | Create Template | Tool to create a new template. Use when you need to programmatically set up reusable document templates after confirming your business settings. |
| `EVERSIGN_DELETE_DOCUMENT_OR_TEMPLATE` | Delete Document or Template | Tool to delete, cancel, or trash a document or template by its hash. Usage: - To cancel a pending/in-process document: Set cancel=True - To trash a document (safer, reversible): Set trash=True - To permanently delete a draft or cancelled document: Use without cancel or trash flags Note: Draft and completed documents must be trashed before permanent deletion. Pending documents must be cancelled before deletion. |
| `EVERSIGN_GET_BULK_JOBS_LIST` | Get Bulk Jobs List | Tool to retrieve a list of bulk jobs for a business. Use when you need to view or paginate existing bulk jobs. |
| `EVERSIGN_GET_BULK_JOB_STATUS` | Get Bulk Job Status | Tool to retrieve the status of a bulk job. Use when you need to check the progress of a bulk sending job, including counts of completed, cancelled, and in-progress documents. |
| `EVERSIGN_LIST_BUSINESSES` | List Businesses | Retrieves all businesses associated with your Eversign account, or filters to a specific business if business_id is provided. This is a read-only operation that returns business details including ID, name, status, and whether it's the primary business. Use this action when you need to discover available businesses before performing operations that require a business context, or to verify business access permissions. |
| `EVERSIGN_LIST_DOCUMENTS` | List Documents | Retrieves a paginated list of documents from your Eversign business account. This tool returns comprehensive document details including signers, status, timestamps, and metadata. Use filters to narrow results by status type, date range, search terms, or signer email. Perfect for monitoring document workflows, tracking signing progress, and building document dashboards. |
| `EVERSIGN_LIST_TEMPLATES` | List Templates | Tool to list templates for a business with optional pagination. Use when you need to retrieve a paginated list of templates. |
| `EVERSIGN_REASSIGN_SIGNER` | Reassign Signer | Tool to reassign a signer to a new person. Use when you need to replace an existing signer on a document before signing is complete. Example: "Reassign the signer alice@example.com on document abc123 to bob@example.com". |

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

The Eversign MCP server is an implementation of the Model Context Protocol that connects your AI agent to Eversign. It provides structured and secure access so your agent can perform Eversign 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 Claude/Anthropic API Key
- Primary know-how of Claude Agents SDK
- A Eversign account
- Some knowledge of Python

### 1. Getting API Keys for Claude/Anthropic and Composio

Claude/Anthropic API Key
- Go to the [Anthropic Console](https://console.anthropic.com/settings/organization/api-keys) and create an API key. You'll need credits to use the models.
- 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).
- Navigate to your API settings and generate a new API key.
- Store this key securely as you'll need it for authentication.

### 2. Install dependencies

## Frequently Asked Questions

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

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

### Can I use Tool Router MCP with Claude Agent SDK?

Yes, you can. Claude Agent 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 Eversign tools.

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

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