Overview

AI-generated overview

Remote MCP server for Lawcus legal practice management: read contacts, matters, leads, tasks and billing reports, and create contacts and tasks.

What you can do
  • Look up the signed-in user, firm details and team members, and run a global search across contacts, matters and leads
  • List, filter and fetch contacts, matters, leads, lead sources, workflows and pipeline stages
  • List tasks and create new tasks, optionally on a matter and assigned to team members
  • Review time entries, expenses, billing items and logged client interactions
  • Run admin reports on accounts receivable, matter balances, attorney revenue, time summaries, payments collected, invoice history and client trust balances
  • Check usage, request a feature, upgrade or cancel the subscription
When to use it
Useful when a firm runs Lawcus and wants an assistant to answer questions about open matters, trust balances, receivables, leads or time and billing without opening the app, or to log a contact or task from a conversation.
Requirements
Remote streamable HTTP endpoint; add only the URL, since sign-in is via OAuth. On first connect you paste a Lawcus API long-life token (from Settings, API Tokens) and choose the US or EU hosting region. Admin role is needed for the report tools. A plan is required beyond the free tier.
Before you install
The Lawcus API token is a long-lived credential granting access to firm data, including client and financial records; treat it as a secret. Two tools write data (creating contacts and tasks) and should be confirmed first. Meta tools can start a paid Stripe subscription or cancel it, and the free tier is capped at 50 calls per month. Report tools expose confidential client and trust-account figures.

Installation

In SourceWeft

  1. Open Lawcus MCP by usefulapi in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.usefulapi%2Flawcus/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

README

Lawcus MCP by usefulapi

Read Lawcus contacts, matters, leads, time and billing reports; create contacts and tasks.

Live endpoint: https://lawcus.usefulapi.io/mcp · Homepage: https://usefulapi.io/lawcus

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://lawcus.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http lawcus https://lawcus.usefulapi.io/mcp, then run /mcp to log in.
  • VS Code: Add to VS Code.
  • Cursor and other clients: add the URL as a remote MCP server:
json
{  "mcpServers": {    "lawcus": {      "url": "https://lawcus.usefulapi.io/mcp"    }  }}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Lawcus credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/lawcus/

On first connect you'll paste a Lawcus API long-life token (Settings → API Tokens) and pick where your firm is hosted (US or EU).
