MCP-NATIVE · INSTALL

A first-class MCP server. One click from Claude or Codex.

LetSign is built MCP-first, from the ground up, from an agent perspective. Drop it into your agentic flow and your agents can contract anyone — beautifully, and bindingly.

BUILT FOR AGENTS, NOT BOLTED ON

MCP-first, from the ground up.

Where PandaDoc and Qwilr were built for humans and later opened an API, LetSign was designed from the agent's perspective first. Every capability is a clean MCP tool your agent composes.

FREQUENTLY ASKED
What does MCP-native mean for LetSign?
It means every LetSign capability is a first-class Model Context Protocol tool. Your agent calls them directly — no bolted-on API, no integration project — so contracting is part of the agentic flow itself.
How do I install LetSign?
Install the LetSign MCP server in one click from Claude or Codex. It drops straight into your existing agentic workflow.
How is this different from PandaDoc or Qwilr?
Those tools were built for humans and later exposed APIs. LetSign is designed from the ground up from an agent's perspective — matching their flexibility and feature set while staying simple enough for agents to contract anyone autonomously.
Does LetSign work with Claude?
Yes. If Claude generates you a proposal, LetSign can attach a style-matched, binding contract in the same flow — one-click install, fully MCP-native.
