AI Toolkit
AI Agents
Everything you need to build, integrate, and operate AI agents with SignatureAPI.
SignatureAPI is built to work alongside AI. Whether you are connecting an off-the-shelf agent through MCP, feeding our documentation into an LLM at build time, or designing an end-to-end agentic signing experience, this section is your starting point.
Connect an agent through MCP
Our hosted Model Context Protocol server lets any MCP-compatible client send envelopes, manage signing, and look up documentation on behalf of an account. Sign in once through OAuth and the agent is ready to act.
MCP server overview
What the server is, the endpoint, transport, and when to use it instead of the REST API.
Connecting clients
Configure Claude Desktop, Claude.ai, ChatGPT, Cursor, Claude Code, and more.
Authorization
OAuth 2.1 with Dynamic Client Registration, discovery endpoints, and the per-tenant pattern for service providers.
Tools and resources
Browse the tools available to agents, including the upload flow and the envelope resource.
Managing connections
Review, rename, and revoke connected applications from the dashboard.
Develop with agents
When you are the developer writing code against SignatureAPI, feed the documentation to your AI coding assistant so it generates accurate integration code.
Use cases
See what becomes possible when an agent drives the entire signing flow.
