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.
The fastest way to connect a coding agent is to let it do the work. Paste this into Claude Code, Codex, Cursor, or any agent that can read a URL:
Set up SignatureAPI for me. Read https://signatureapi.com/docs/ai-toolkit/mcp/connecting-clients.md
and follow the section for the agent you are running in. If I am working on a codebase, install the
SignatureAPI plugin (skills plus MCP server) rather than the MCP server alone. Ask me before opening
a browser for sign-in, and never print tokens or keys. When you are done, prove it works by listing
my 5 most recent test-mode envelopes, then tell me what you changed and how to undo it.Prefer to do it yourself? Connecting clients has a one-command installer, one-click buttons for Cursor and VS Code, and manual steps for every supported app.
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, Codex, 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.
Agent skills and plugin
Two skills that build and diagnose e-signature integrations, installable alone or as a plugin with the MCP server.
llms.txt
Discoverable indexes of the SignatureAPI documentation, designed to be consumed by LLMs at build or prompt time.
Context7
Pull up-to-date SignatureAPI documentation into Cursor, Claude Code, and other MCP-aware editors via Context7.
