This guide uses Atomic Agent's built-in Composio integration. You need Atomic Agent v0.5.6 or later, your own Composio API key, and a Signwell account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions. ## Also integrate Signwell with - [OpenAI Agents SDK](https://composio.dev/toolkits/signwell/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/signwell/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/signwell/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/signwell/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/signwell/framework/codex) - [OpenClaw](https://composio.dev/toolkits/signwell/framework/openclaw) - [Hermes](https://composio.dev/toolkits/signwell/framework/hermes-agent) - [Google ADK](https://composio.dev/toolkits/signwell/framework/google-adk) - [LangChain](https://composio.dev/toolkits/signwell/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/signwell/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/signwell/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/signwell/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/signwell/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/signwell/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/signwell/framework/autogen) ## TL;DR ### How Atomic Agent connects to Signwell Atomic Agent connects to Composio's Tool Router over Streamable HTTP MCP. It discovers the tools needed for your request, and Composio handles account authentication. Execution and account-connection tools follow Atomic Agent's configured approval policy. Review any approval prompt before allowing an action on your connected account. ## Connect Signwell to Atomic Agent ### Connect Signwell to Atomic Agent - Sign up or sign in to the [Composio dashboard](https://dashboard.composio.dev/?cta_placement=atomic-agent-api-key). Copy your API key. - In Atomic Agent, open the Integrations tab and select Composio. Select API key, press e, paste the key, and press Enter. The tools become available immediately, without a restart. - Ask Atomic Agent to do something in Signwell. It searches Composio for the right tool. - On first use, open the sign-in link returned in the chat. Connect your Signwell account, then return to Atomic Agent to continue. ### Headless setup Add the following line to ~/.atomic-agent/.env, replacing YOUR_COMPOSIO_API_KEY with your key. Start Atomic Agent after saving the file. ```bash COMPOSIO_API_KEY=YOUR_COMPOSIO_API_KEY ``` ## What is the Signwell MCP server, and what's possible with it? The Signwell MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Signwell account. It provides structured and secure access to your document signing workflow, so your agent can perform actions like sending signature requests, managing documents, handling webhooks, and retrieving account info on your behalf. - Automated document creation and sending: Have your agent generate new documents and instantly send them out for e-signature—no manual uploads or email juggling required. - Real-time document status retrieval: Let your agent fetch the latest status and details of any document, so you always know who has signed and what’s still pending. - Bulk send management: Effortlessly list and track large batches of signature requests, helping you stay organized when sending documents to multiple recipients. - Webhook automation and monitoring: Register or remove webhooks so your agent can monitor document events and respond instantly to completed, signed, or cancelled documents. - Credential and account validation: Quickly check and verify your Signwell account details and API credentials directly through your agent. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `SIGNWELL_CREATE_DOCUMENT` | Create Document | Tool to create and optionally send a new document for signing. Use when you have files and recipients defined and want to programmatically submit a signature request in one call. | | `SIGNWELL_CREATE_DOCUMENT_FROM_TEMPLATE` | Create Document from Template | Tool to create and optionally send a new document for signing from a template. Use when you need to generate a document using a pre-configured template with placeholders. If draft is set to true the document will not be sent. | | `SIGNWELL_CREATE_WEBHOOK` | Create Webhook | Tool to register a webhook callback URL. Use when you need to receive document event notifications. | | `SIGNWELL_DELETE_DOCUMENT` | Delete Document | Tool to delete a document (and cancel signing if in progress). Use when you need to remove a document by ID after confirming it. | | `SIGNWELL_DELETE_WEBHOOK` | Delete Webhook | Deletes a registered webhook by its ID. Use this to remove webhooks that are no longer needed. Returns no content on success. | | `SIGNWELL_GET_CREDENTIALS` | Get Credentials | Retrieve account information for the authenticated API key. Returns comprehensive details including user profile, account settings, workspace configuration, and contact information. Use this to validate API credentials, check account capabilities (like template creation limits), or get user/account IDs for other API calls. | | `SIGNWELL_GET_DOCUMENT` | Get Document | Tool to return a document and all associated document data. Use when you need to fetch document details by ID. | | `SIGNWELL_LIST_BULK_SENDS` | List Bulk Sends | Tool to list all Bulk Sends. Use after setting up API credentials to retrieve paginated records. | | `SIGNWELL_LIST_WEBHOOKS` | List Webhooks | Tool to list all registered webhooks. Use when you need to retrieve the active webhooks for your SignWell account after setup. | | `SIGNWELL_SEND_REMINDER` | Send Reminder | Tool to send a reminder email to recipients that have not signed yet. Use when you need to prompt unsigned recipients to complete their signature. | | `SIGNWELL_UPDATE_AND_SEND_DOCUMENT` | Update and Send Document | Tool to update a draft document and send it to recipients for signing. Use when you need to modify document settings and initiate the signing process. | | `SIGNWELL_UPDATE_TEMPLATE` | Update Template | Tool to update an existing template in SignWell. Use when you need to modify template properties such as name, subject, message, reminders, expiration, or other settings. | ## Supported Triggers None listed. ## Troubleshooting ### Why is my API key rejected? Copy the key directly from the Composio dashboard. Atomic Agent requires ASCII characters because it sends the key in an HTTP header. Remove any extra characters introduced when copying. ### Why are Composio tools unavailable after saving a key? Check that you use Atomic Agent v0.5.6 or later and that Composio is enabled in your configuration. A "composio": { "enabled": false } setting disables the integration while keeping the saved key on disk. ### Does Composio have a free plan? The Hobby plan includes 100,000 tool calls per month. Composio-managed OAuth apps have a lower included allowance. See [Composio pricing](/pricing) for the current limits that apply to your connection. ## Complete Code None listed. ## Conclusion ### Use Signwell from Atomic Agent With your account connected, ask Atomic Agent to work with Signwell in natural language. You can connect more apps through the same Composio integration as you need them.

With a standalone Signwell MCP server, the agents and LLMs can only access a fixed set of Signwell tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Signwell and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with Atomic Agent? Yes, you can. Atomic Agent 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 Signwell tools. ### Can I manage the permissions and scopes for Signwell while using Tool Router? Yes, absolutely. You can configure which Signwell 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 Signwell data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
