Think of it as Claude Code for everything else. It works autonomously with your computer, local files, and applications to accomplish complex tasks. This guide walks you through the easiest and most secure way to connect your Esignatures io account to Cowork via Composio Connect, enabling it to send a contract to a new client for signature, list all available contract templates, withdraw a contract that hasn't been signed, and more such actions on your behalf without compromising your account security. ## Also integrate Esignatures io with - [OpenAI Agents SDK](https://composio.dev/toolkits/esignatures_io/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/esignatures_io/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/esignatures_io/framework/claude-code) - [Codex](https://composio.dev/toolkits/esignatures_io/framework/codex) - [OpenClaw](https://composio.dev/toolkits/esignatures_io/framework/openclaw) - [Hermes](https://composio.dev/toolkits/esignatures_io/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/esignatures_io/framework/cli) - [Google ADK](https://composio.dev/toolkits/esignatures_io/framework/google-adk) - [LangChain](https://composio.dev/toolkits/esignatures_io/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/esignatures_io/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/esignatures_io/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/esignatures_io/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/esignatures_io/framework/crew-ai) ## Connect Esignatures io to Claude Cowork ### Connecting Esignatures io to Claude Cowork 1. Open Customize In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top. 2. Add the Composio MCP server Click Add custom connector and paste in the Composio MCP server URL: ```bash https://connect.composio.dev/mcp ``` ## What is Claude Cowork? Claude Cowork is Anthropic's agent for general knowledge work. It can use your computer, files, and connected applications to complete longer-running tasks across your work tools. With Composio Connect, Cowork can securely access apps like Esignatures io through MCP without you sharing account credentials directly with the agent. ## 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.

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 Claude Cowork? Yes, you can. Claude Cowork 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. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
