Overview

AI-generated overview

Loupe checks every citation in a US legal filing — cases, statutes, quotations and links — so an assistant can verify them before you sign.

What you can do
  • Check citations in a US legal filing, covering cases, statutes, quotations and links.
  • Verify cited authorities and quoted text before a filing is signed.
  • No individual tools are documented in the supplied listing, so the exact operations are not described.
When to use it
Use it when preparing or reviewing a US legal filing and you want an assistant to check that its citations, quotations and links are correct before signing.
Requirements
A remote MCP endpoint at loupe.legal over streamable HTTP, with OAuth sign-in required. No packages, environment variables or headers are declared.
Before you install
Filing content you submit is sent to a third-party service, and access is tied to an OAuth account. The listing does not describe what the server stores or changes, so confirm that before relying on it.

Installation

In SourceWeft

  1. Open Loupe: citation checker for US legal filings in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. 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/legal.loupe%2Fcitation-checker/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

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.

83% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
