JustDocs Developers

Appearance

Developer docsCreate it. Send it. Sign it. Done. Now for your software and agents.

Templates, documents, signing requests and intake links, through a REST API, an MCP server and signed webhooks. Agents can prepare a document and ask to send it. A person approves it first.

Quick start
Connect an agent
REST API reference

MCP server

Fourteen tools at tryjustdocs.com/mcp over Streamable HTTP. Listed in the official MCP Registry as com.tryjustdocs/justdocs.

The MCP server

REST API

The same commands at /api/v1, with idempotent retries, cursors and an OpenAPI description.

The REST API

Webhooks

Signed events for sends, views, signatures, completions, intake answers and approvals, retried for about 20 hours.

Webhooks

A person approves first

When an agent asks to send something, an owner or admin approves it first. No key can sign for anyone or read a signing link.

The safety model

Connect in a minute ​

Add https://tryjustdocs.com/mcp to a client that signs in with OAuth (Claude, ChatGPT, Muse): it asks you to sign in and choose what it may do. See Sign in with OAuth. Or make an agent key on your workspace's API & agents page, on any plan, then add the server to your client:

bash
claude mcp add --transport http justdocs https://tryjustdocs.com/mcp \
  --header "Authorization: Bearer $JUSTDOCS_AGENT_KEY"
json
{
  "mcpServers": {
    "justdocs": {
      "url": "https://tryjustdocs.com/mcp",
      "headers": { "Authorization": "Bearer ${env:JUSTDOCS_AGENT_KEY}" }
    }
  }
}
bash
curl https://tryjustdocs.com/api/v1/templates \
  -H "Authorization: Bearer $JUSTDOCS_API_KEY"

Then ask your agent to "draft a mutual NDA for Acme from our template and send it to Ada". It prepares the document and asks to send it. You approve it under Approvals, and only then is the email sent. Every client →

Where to start ​

Built for agents ​

  • One set of commands. Each MCP tool is a REST operation with the same name, inputs and checks, so what you test with curl is what your agent gets.
  • Least privilege. Keys carry permissions (read, documents, send), recipient domains, a daily send limit and an expiry. You can revoke a key at any time.
  • Human approval. An agent can't send a document to anyone until an owner or admin approves. An approval expires after seven days.
  • No signing by machines. Recipients sign from the private link JustDocs emails them. No tool or endpoint returns that link or signs for anyone.
  • Readable by assistants. Every page is also available as Markdown, and the whole site is in llms.txt.
