# AI tools

An MCP server and agent skills. Sending, reminding and voiding preview first and act only on a confirmed second call. Every docs page is also served as Markdown.

## What an assistant can do

The MCP server gives an AI assistant tools to list templates, read documents and their audit logs, save signed copies, send a document, send a reminder, void a document and make a template from HTML. It runs on your computer with your own API key.

## Safe by design

Sending, reminding and voiding do nothing on the first call: they return a plain-words preview of who would be emailed, and only a second call with confirm set to true acts. A read-only setting removes every tool that changes anything. No tool returns a signing link, a code or the key.

## Skills for agents

The Docustay plugin for Claude Code bundles the server and five skills: sending for signature, text tags, embedded signing, webhooks and agent safety. The skills are plain Markdown files, so any agent that reads skill files can use them.

## What an assistant can and cannot do

The tools let an assistant send a document from a template, check where it stands and fetch the signed copy, with the permissions of the key you give it. They are not a way around anything: a key with read scope only reads, and every action lands in the same audit log as a person's would.

## Try it with test mode on

Give the assistant a test key first. It can then practise sending and reading documents without a real signer ever receiving anything, and you can see exactly what it did in the document list before you give it a live key.

## Add the server to an assistant

```
{ "mcpServers": { "docustay": { "command": "npx", "args": ["-y", "@docustay/mcp"], "env": { "DOCUSTAY_API_KEY": "dsk_test_..." } } } }
```
