@actalumen/mcp-server

MCP server for ActaLumen — verify documents for compliance from Claude Desktop, Cursor, and Claude Code.

What it does

Exposes ActaLumen's verification, chat, and document tooling to any MCP-compatible AI agent. Your agent can upload a contract, run it against a compliance template (SOC2, GDPR, custom), and chat with the document — all grounded in citations.

PII is redacted server-side before storage. Agents never see un-redacted content, even when explicitly asked.

Install

Easiest: MCPB bundle (Claude Desktop one-click)

Download actalumen-<version>.mcpb from the latest release and double-click it. Claude Desktop will prompt for your API key and upload directory, then install. No Node, no JSON editing.

Or via npm (Cursor, Claude Code, custom MCP clients)

Prerequisites

1. An ActaLumen API key with read, write, and verify scopes. Create one at app.actalumen.com → Settings → API Keys.

2. Node.js 18.17 or newer.

3. A directory the agent is allowed to upload from. Default: ~/actalumen-inbox (create it: mkdir ~/actalumen-inbox).

Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "actalumen": {
      "command": "npx",
      "args": ["-y", "@actalumen/mcp-server"],
      "env": {
        "ACTALUMEN_API_KEY": "ak_live_..."
      }
    }
  }
}

Restart Claude Desktop. You should see the ActaLumen tools in the tools menu.

Cursor

Add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "actalumen": {
      "command": "npx",
      "args": ["-y", "@actalumen/mcp-server"],
      "env": { "ACTALUMEN_API_KEY": "ak_live_..." }
    }
  }
}

Claude Code

claude mcp add actalumen -- npx -y @actalumen/mcp-server
# then set the key in your shell or settings:
export ACTALUMEN_API_KEY=ak_live_...

Configuration

Tools

Example agent flow

"Check whether ~/actalumen-inbox/acme-msa.pdf meets our SOC2 vendor requirements and summarize the gaps."

The agent will:

1. list_templates → find the SOC2 template.

2. upload_document → get a document ID, wait for READY via get_document.

3. start_verification → get a jobId.

4. get_verification (polling) → receive the full report.

5. Summarize the failed criteria back to you with page citations.

Verify your install

ACTALUMEN_API_KEY=ak_live_... npx -y @actalumen/mcp-server --health
# → ok — https://api.actalumen.com — org Acme Inc — upload dir /Users/.../actalumen-inbox
