SignatureAPI for AI Agents

Enable your AI agents to send and manage signed document with SignatureAPI.

Model Context Protocol (MCP) is an open protocol to standardize how applications provide context to LLMs. SignatureAPI provides an MCP server to enable AI agents to send and manage signed documents.

This page describes the tools available in SignatureAPI’s MCP server, which allows AI agents to interact with the SignatureAPI platform.

Our MCP server is currently in private beta. If you’re interested in early access, please get in touch with us.

Currently available tools

Tools are individual operations exposed by the SignatureAPI MCP server. Each tool corresponds to a specific API capability, such as creating an envelope, retrieving a recipient, or uploading a file. These tools are grouped by resource type and can be invoked by LLM agents through the MCP protocol.
