Documenso MCP server

Ask Claude about your contracts in plain words: which ones are still waiting, who hasn't signed (and who hasn't even opened them), what happened to one document. Send reminders and drafts from the same chat, with a confirmation step before any email goes out. There is no tool that signs on anyone's behalf.

Built by Mojood Connect as a working demo for Documenso. It runs against any Documenso through its v2 public API. This repository includes a local Documenso with SAMPLE contracts for a made-up company, Harbor Trading, and a local mail catcher, so you can try it without sending a single real email.

Tools

How sending is made safe. A call to send_reminder or send_draft without a confirmation sends nothing: it returns a plain summary ("Email a reminder to sign "Distribution agreement: Gulf Build Contracting" to Rashid Al-Mutairi (rashid@gulf-build.example), sent 8.0 days ago.") and a one-time code. The email goes only when the same request comes back with that code, within 10 minutes. A code works once, and only for the request it was issued for. The server's instructions tell the model to show the summary and wait for the user's yes. Documenso's own audit log records every reminder and send.

The server acts for the team that owns the API token.

Try it locally

Needs Docker (with Compose), uv, Python 3.13 and OpenSSL.

scripts/reset.sh                         # local Documenso on http://localhost:3020, filled with the SAMPLE contracts
uv run --env-file .env documenso-mcp     # MCP server on http://127.0.0.1:8007/mcp (Streamable HTTP)

Every email Documenso sends lands in Mailpit at http://localhost:8026 and goes nowhere else. docker/compose.yml follows Documenso's own docker/production/compose.yml (v2.21.1), pinned, on 127.0.0.1 only. scripts/up.sh makes a self-signed signing certificate, signs the demo user up through Documenso's own sign-up endpoint and creates its API token the way Documenso stores them (the SHA-512 of the token); every secret stays in the git-ignored files docker/.env, docker/cert.p12 and .env, and nothing is printed.

Claude Desktop: add this to claude_desktop_config.json (Settings › Developer), with the path to this folder:

{
  "mcpServers": {
    "documenso": {
      "command": "uv",
      "args": ["run", "--directory", "/path/to/documenso-mcp", "--env-file", "/path/to/documenso-mcp/.env", "documenso-mcp", "--stdio"]
    }
  }
}

Then ask: "Which contracts are still waiting on signatures, and who hasn't signed?", "Where are we with the Gulf Build agreement?", "Remind Rashid to sign it."

Your own Documenso: set DOCUMENSO_URL, DOCUMENSO_TOKEN (an API token from your team's settings) and DOCUMENSO_SAMPLE=0.

The SAMPLE contracts

Eight one-page SAMPLE documents for Harbor Trading: a supply agreement waiting on our own countersignature, an NDA opened but not signed, a distribution agreement the customer hasn't opened in eight days, an offer letter, two completed contracts, an NDA rejected for the wrong legal entity name, and a draft. Times are set relative to the moment it is seeded. Everyone and everything in it is made up.

Tests

uv run --env-file .env pytest            # unit tests (a fake Documenso API), plus live tests when the local Documenso runs

What a production version adds

This demo uses one team's API token. A production server for Documenso customers would add sign-in with each person's own Documenso account, so Claude sees exactly their teams; hosting with an audit log of every tool call; and more of the API (templates and "use template", envelopes with several files, fields, webhooks). That is what Mojood Connect builds.
