Overview

AI-generated overview

Remote MCP server that looks up a company's parent chain and subsidiaries using GLEIF LEI data, paid per call.

What you can do
  • Look up a company's corporate ownership structure from GLEIF LEI data
  • Trace the parent chain upward from a given company
  • List subsidiaries below a given company
  • No individual tools are documented; the description only names these two lookup capabilities
When to use it
Useful when you need to check who owns a company or which entities sit beneath it, for example during due diligence, supplier or counterparty checks, or corporate structure research.
Requirements
A remote streamable HTTP endpoint; no local install, package, account, API key or environment variable is declared. Calls are billed at $0.02 each through x402, so a payment-capable client is needed.
Before you install
Each call costs $0.02 via x402, so automated or repeated queries spend real money. The service is a third-party hosted endpoint, and the company names you query are sent to it. Results depend on GLEIF LEI coverage and may be incomplete for entities without an LEI.

Installation

In SourceWeft

  1. Open Corporate Ownership Tree (GLEIF) 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.github.pcp183%2Flei-ownership/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.

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.
