@sharedanchor/professional-mcp

Read-only MCP (Model Context Protocol) connector that lets a family-law attorney query their client's SharedAnchor co-parenting records inside Claude Desktop, using a scoped access key issued by the client.

The connector exposes three read-only tools (list_expenses, list_payments, list_custody_events) backed by the SharedAnchor production API. The client controls the key and can revoke it at any time from SharedAnchor Settings.

What this is for

If a SharedAnchor client has sent you a "Professional Access" invitation email, this package is the local connector that wires up Claude Desktop so you can ask things like:

"List approved expenses over $100 last quarter." "Show payments my client made in March." "Pull custody days for the last 90 days."

Install

npm install -g @sharedanchor/professional-mcp

Or run on demand without a global install:

npx -y @sharedanchor/professional-mcp

Node.js 18 or later is required.

Configure Claude Desktop

Open Claude Desktop's claude_desktop_config.json file and add the sharedanchor entry inside mcpServers:

{
  "mcpServers": {
    "sharedanchor": {
      "command": "npx",
      "args": ["-y", "@sharedanchor/professional-mcp"],
      "env": {
        "SHAREDANCHOR_API_KEY": "paste-your-access-code-here"
        // "API_BASE_URL": "https://api.sharedanchor.com"  // optional; defaults to production
      }
    }
  }
}

Config file location:

• Mac: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

Replace paste-your-access-code-here with the access code from your invitation email (it starts with pro_). Save, then fully quit and reopen Claude Desktop.

Environment variables

| Variable | Required | Default | Description | |----------|----------|---------|-------------| | SHAREDANCHOR_API_KEY | yes | — | Your scoped attorney access code (starts with pro_). | | API_BASE_URL | no | https://api.sharedanchor.com | Override only if SharedAnchor support directs you to. |

The key is stored only in Claude Desktop's config file. It is sent to api.sharedanchor.com with each query, but never to any other party.

Troubleshooting

• Claude shows no SharedAnchor option. Fully quit Claude Desktop (Cmd+Q on Mac, right-click the tray icon and choose Quit on Windows). Closing the window is not enough.
• command not found: npx. Node.js is not installed or the installer needs a system restart. Install it from nodejs.org, then restart your computer.
• "API key is invalid". Double-check that you copied the full access code (including the pro_ prefix) and that the surrounding double-quotes in the config file are intact.
