Agents asked to integrate with an e-signature product invent endpoints — confidently, with plausible names — and every one of those is a Not Found somebody finds by hand later. This site runs a Model Context Protocol server so that an agent writing your integration can search these docs, and read any page in full, including every page of the API reference, instead.
Any client that speaks MCP over HTTP can use the same URL: https://docs.vumasign.com/mcp. It needs no key. It reads documentation, and the only thing it can send is a report to our docs team that a page is wrong or unclear. It holds no credential and cannot send an envelope, read your account, revoke a key or mint a signing URL — a signing URL is a bearer credential for a legal act, and a model will put it in a transcript. For anything that touches real data, call the API with your own key. For a tool that reads plain text rather than MCP, the same pages are indexed at https://docs.vumasign.com/llms.txt, and served in full at https://docs.vumasign.com/llms-full.txt.
